David O. has been a Z Car Garage client since 2005. Together, we helped achieve his vision of a fully restored S30 with multi-dimensional performance: a daily driver that is equally adept at canyon runs and open track events. 17 years later David is still Enjoying the Ride and recently visited us for track day preparation.
Before we get into the build details dating back to 2005, let’s hear from David on his recent track day experience.
Take it to the Track!
David is an avid motorsports fan and driver. The Z has seen many track days since the restoration and came out of storage so he visited Z Car Garage for a pre-inspection.
We bled the brakes and made sure everything was ready for the event. He had a great time:
“It was my first time back on the track with the 240z in several years. I went out for half a day with Hagerty Insurance and their affiliation with SCCA’s Track Night in America. The people were great and it was a very “docile” track day with mandatory point-by’s even in the advanced group. It was a great way to knock the rust off after a few years off the track.”
“Rob Fuller prepped the car a few days before and she behaved beautifully. I managed a 1:59 lap but I was lifting a bit going up to turn six because I was afraid of breaking the 90dB sound limit. Of course, Z-Car got a lot of love from the other attendees. :-)”
Enjoy this video of David’s Z in action with in-car and chase footage from Laguna Seca and more:
History
We met David and his newly acquired Z in 2005. Long before the days of Facebook and Instagram, our mutual friend and Datsun fanatic Tom Dockery referred David to ZCG:
“I’ve been working with Rob since February of 2005 when I purchased my 240z from a guy in Redding. It was a true barn car. He drove it down and Rob inspected it before I bought it. I didn’t know anything about the car except that I wanted something fun to drive with a manual transmission. I’d always thought the 240z was cool because my 5th and 6th grade teacher had one – and she was very cool.”
“The first weekend I had the car it rained really hard and I found out all the seals were useless. There was about a quarter inch of water in the car and mold had already started growing. I took it to Rob, and once the seats were out, and the carpet was out, and the seals were in, Rob suggested the Recaro seats, the roll bar, and harness. It was just about that time I did my first track day in someone else’s car, and I decided I wanted to track the 240z. And that’s when I started what I call the “accidental restoration.”
Paint/Body
While we do not have in-progress photos of the restoration, there are many shots of David enjoying the finished restoration. Our man William worked his magic to apply the Nissan 112 Paint (Tennis Ball Green). David recalls his vision for the Z:
“My goal when restoring was to have a track-ready, fun to drive machine that did justice to the original car. My car was originally orange, was red when I purchased it, but I wanted something different. That’s when I went with the tennis ball green color, which was one of the original colors. It was manufactured in October of 1971, so she turned 50 just last fall.”
Engine
Full engine bay services included re-plating and powdercoating parts. The L24 was replaced with factory-spec L28 with triple-Mikuni induction. A custom cam was designed by Rob for better top-end performance. The Z put down 167hp/174tq at the wheels on the ZCG dyno:
Interior
There’s very little on the car that was left untouched – David took pride in the interior:
“I pretty much went with Rob’s suggestions (pros and cons) and learned while I went along. The gauges were all me. As much as I liked the originals, the were just too dim and difficult to read at night. I replaced them with white-backed Autometer gauges but kept the green backlighting. I also kept the original turn signals and embedded them in the new gauges. I didn’t keep the clock, and the fuel gauge is the carbon fiber reinforced glove box.”
More details like Recaro seats, Roll bar with 5-point harnesses, updated fuse box and high voltage bypass for the steering column, 260z lighted console panel and Sony bluetooth radio. Outside, Euro tail lights with LEDs:
Z Car Garage Big-Brakes
David’s Z was the first one to receive our Z Car Garage Big-Brakes. This was our initial (2008) setup utilizing Stoptech ST-40 calipers and our own brackets. We had extensive track testing with pro-driver David Ray:
We have Enjoyed the Ride with David at many events over the last 17 years. Most recently I got to catch up with him at our New Nissan Z event. His Z still looks amaZing!
Here are few events from years ago with David…some of you might remember attending these too!
2008 ZONC Blackhawk Museum Car Show
2010 and 2011 Palo Alto Concours d’ Elegance – the crowd loved his Z car!
2008 Motoring J Style…remember we had a superb turnout for the caravan starting at Z Car Garage!
2008 and 2011 Silicon Valley Auto Show at the San Jose Convention Center
Long Live The Z!
Thank you David for your support and friendship all these years. We love that you keep your Z on the road and it makes you smile behind the wheel whether its on the track or or street. Stay tuned as David will be returning to ZCG later this year for 3.1L engine upgrade! More pictures in the gallery below… …[read more]

Dear Zcarblog readers, it’s been a busy year and we are catching up on blog posts, so please enjoy our belated race report from November 2021.
WE LOVE RACING! On November 11-14 we attended the Velocity Invitational at Weathertech Raceway Laguna Seca. Z Car Garage had a blast racing and supporting several client’s IMSA GTU Z cars running in Group 7A (1966-1977 IMSA GT). This vintage racing event was just as fun for spectators with a friendly, immersive vibe. Enjoy our report from the weekend with photos and in-car video of the action.

Z Car Garage IMSA Race Car Support!
If you missed our earlier post, we prepared and supported three IMSA race cars for the Velocity Invitational (VI). Here’s a quick review:
We supported our client Randy Jaffe who recently acquired the Transcendental Racing Datsun 240Z. This famous 1976 IMSA-GTU Championship-winning 240z will be driven by ex-driver Brad Frisselle’s son, Brian Frisselle. Randy recently had the Z re-painted by William with correct graphics and hand-applied livery by the Real Ralph.
#93 Different Drummer Racing Datsun 260Z
Race car driver, restorer and Datsun Historian Glenn Chiou raced his Ex-Greg Sorrentino IMSA 260Z. Glenn built and prepared this race car by himself, ZCG simply dyno-tuned it prior to race week.
Ready for some L-series music from these historic race cars on the dyno? Check out the video below and turn those speakers up!
We also prepared our client Kelvin Tse’s Porsche 911 RSR, because if it’s not the Z-car, it’s the P-car!
Epic Racing With Group 7
Photo by Kristina Cilia
Group 7’s IMSA GT and FIA race cars (1966 and 1977) was dominated by big-power Porsche 911 RSRs with a few BMS CSLs and 4 S30 Datsuns. Speaking of powerful Porsche’s, the organizers did not allow turbocharged cars to run so we thought an NA motor race would make things interesting. Read more about Group 7 here with driver Jeff Francis in Larry Oka’s 1970 Ex-Glemik IMSA Datsun 240Z (#54):
Friday’s qualifying race was eventful. Rob and Brian Frisselle were doing well and putting down some great lap times. Unfortunately, a Porsche oiled down the track between turns 4 and 5 and both Z cars skidded off the track. They recovered under their own power but the Frisselle Z sustained minor body damage from hitting the tire barrier. Good news: Glenn, Jeff and John Murray avoided the mess and Rob Fuller qualified on Pole Position!
Racing in to the Night
Saturday’s Group 7 would start at dusk, a rare exhibition for both drivers and spectators. I zipped up to my favorite vantage point at Turn 6 to catch the sunset. Auxillary lights were placed at each apex and few cars had headlights of their own to navigate the evening’s race. It was magical to watch. Here is Rob Fuller re-capping his sessions from the #49 Joel Anderson IMSA GTU 240Z:
“We had a great first session, made some adjustments to the cars and clicked-off good times. The qualifier was pretty scary as I lost control from a Porsche’s oil spill but I made it out ok. Brian Frisselle is an ex-IMSA professional driver and he safely negotiated the oil slick, avoiding a potentially severe impact with the sitting Porsche and softly hitting the tire barrier. I was surprised to make Pole-Position. Saturday’s evening race was intense. Though I started on Pole, by Turn 2 the Porsche gapped me 3-4 car lengths…
…We were racing our Datsuns with skilled drivers like Ned Bacon, Alan Terpins, and Martin Lauber in their multi-million $ Porsches. I was able to hold on to 2nd place, trying hard to reel Ned in but caution struck again, another Porsche had oiled down the track between Turn 5-6. Now its really dark and I’m trying to stay with Ned then I see these lights coming up hard on me and I know it’s Terpins. Tried to defend but he got around me. Honored to be amongst these guys who never let up. We finished the race in 3rd place.”
Enjoy this video we made highlighting the Group 7 races with in-car, Turn 6 and Goodwood livestream footage mixed in. Volume up!
You can see full, in-car footage from Rob in the#49 Joel Anderson IMSA 240Z over on his YouTube Channel, check out the Qualifying and Saturday Evening sessions. Here is Rob recapping the Sunday race from Group 7:
“Final race was midday with plenty of sunshine. Frisselle started 4th. Three lead Porsches took off, while Brian and I battled for P4. He then got around me and we both enjoyed the magic of driving our IMSA cars. Drivers around me were in expensive machines giving it 100%. Really happy to see 4 Datsuns in top 10 places. Honorable mention to John Murray (narrow body 260Z), Glenn Chiou did a really good job (Greg Sorrentino IMSA 260Z) and Jeff Francis (Ex-Glenn Klemik IMSA Z).“
Joel Would Be Proud
You might recall the story behind this special, 1972 IMSA GTU 240z as it was owned, built and raced in the 70’s by none other than Joel Anderson. ZCG restored #49 back to its former glory and it debuted at RMMR 2014. John Morton would drive #49 at RMMR 2015. Rob Fuller would drive #49 for the first time at the RMMR 2018. Joel was present at all of those events but sadly passed away March 2021 and we miss him dearly.
“This was unbelievable…driving the Z without Joel around was so emotional. Thinking about the fact that all of the vintage race support and seat time we have is all because we met Joel. He taught us how to be racers. His memory was shared by us all at the race.”
Privateer Spirit

Our friend and Datsun Historian Glenn Chiou raced his Ex-Greg Sorrentino IMSA 260Z. It’s worth noting that not unlike privateers of the period, Glenn builds his Z cars, maintains and manages his racing efforts himself. Not an easy task so we applaud his work ethic.
A Fan-Friendly Race Event
Photo by Kevin Ehrlich
Formerly known as the Sonoma Speed Festival (2019), the Velocity Invitational re-imagined the vintage race experience with a Goodwood-inspired vibe. One of the best experiences for spectators is the paddock and organizers made access to drivers and their machines seamless. Fans could get up close and personal with race cars without the typical ropes or 45-foot RVs in the way. It was a dream come true for me to share vintage racing with my family, they loved it!
The hot pit area where all run groups stage before heading out to the track is an amazing place to be. Typically, access is only granted to pit crews and media. At the Velocity Invitational however, organizers staged a “false grid” where any spectator could walk amongst the race cars. Our family loved the artificial turf and hay bale seating lining the grid:
Though the fresh format was immediately enjoyable for spectators, it did come as a surprise to drivers and race teams. Rob’s initial reaction was met with eventual praise:
“Upon arrival to ‘Seca we knew this was going to be a different kind of event. All race cars were displayed together under white tents in the paddock for a Goodwood-like experience. It allowed spectators to see all cars within each race group but it was challenging for the team as our tools and support vehicles are usually near us. Initially we were intimidated but got the hang of it with just our essentials. The layout encouraged interaction and it was super fun to meet other racers, new folks and see old friends. Kudos to the organizers for doing something new and absolutely knocking it out of the park!”
Enjoy this video we made showcasing the sights and sounds of the Velocity Invitational. Rob Fuller gets interviewed by the Goodwood Livestream just before the evening race, and I included the lineup from my favorite vintage race group (other than IMSA), the Trans Am cars!
If you want to see action from the event in its entirety, check out Goodwood’s live streaming coverage Day one and Day Two.
Paddock Finds
At each corner there was something special in the paddock to see like exotics, Muscle Cars, personal sports cars and even Ragtime racers. The paddock never disappoints. Here’s a few of my favorites, more in the gallery! Where else can you see a brace of McLaren Speedtails, Lamborghini Mirua, Mercedes Benz 300 SLR and Lotus Cortina in one place!
Exotics abound with Bugatti and McLaren hypercars:
Really excited to spot this Datsun 240Z in the car corral…it is Z Car Garage client Matt K. Full report soon on this pretty Z car that features our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles!
We have more photos in the gallery below.

Happy New Year! Today we kicked off 2022 the right way with a New Year’s drive on a beautiful California day. Our friend Geoff assembled a group of cars and we were pleasantly surprised to see several Z Car Garage clients and friends in attendance! Thank you to everyone that braved the chilly morning temperatures and truly showed that Datsuns Are Driven! Enjoy photos and video from the cruise below.
I drove my 1967.5 Datsun Roadster and it was a cool 36F at 8:30am as I hit the freeway for the meeting point in San Jose. It was so good to see familiar faces and cool cars. Geoff briefed the group and we rolled out 16 cars strong heading up HWY 17 to Bear Creek Rd. Let’s take a look at the group:
Glenn Chiou drove his RHD Fairlady Z sporting our Z Car Garage Big-Brakes (for small wheels). He is an avid vintage race car driver/restorer and found our brake kit offers incredible brake feel and performance all fitting behind his favorite 15×8 zero offset Watanabe wheel:
Jose M was happy to join us in his Z. After 8 years, Rob and Jose re-connected at our 2023 Nissan Z Viewing.
Felix’ 1996 Nissan 300ZX Twin Turbo
Felix joined is in his 1996 Z32TT. This 300 will also get an updated feature on zcarblog.com.
Pall’s Nissan Skyline GT-R
Pall’s R32 recently visited ZCG for Haltech ECU and dyno tuning.
Datsun 510s
We had three Datsun 510s in Wagon, 2-door and 4-door models!
Mark’s 1972 Datsun 510
We upgraded Mark’s 510 with our Z Car Garage CV Axles. These CV axles help transmit power to the ground and ensure smoother operation compared to standard half shafts, while eliminating the need for aluminum adapters. Mark got ZCG VV Axle set #320 and he loves them:
Nick’s Datsun 510 Wagon
Z Car Garage’s very own Nick F drove his L-Series powered 510 wagon with SSR mesh wheels.
Dustin’s Datsun 510 4-door
We’ve known Dustin and Courtney for many years. Dustin’s 510 4-door runs a KA24DE and sweet Longchamp XR-4 wheels. Hagerty produced a video featuring the local Bay Area Datsun couple you can see it HERE. Dustin also installed our Z Car Garage CV Axles himself on his 510!
Our fearless leader Geoff in his Lotus 7 and my Datsun Roadster. Also joing us was William in his (964) 911:
Enjoying The Ride
Bear Creek Rd. up to HWY 9 to the look out was surprisingly traffic-free. At the lookout we could see clear across the Santa Cruz mountains to the coast. A few late-model Porsche’s stopped by.
Enjoy this video of the drive and all cars particiapting:
From the lookout we drove up Skyline (35) and down Alpine Rd. Recent rains have made lush forests:
After a short re-group we took 84 up to Alice’s Restaurant and chatted for a bit. It is always busy here and the eye-candy endless. My J-Tin radar was treated to Mark 3 and 4 Supras, S14 240SX, R35 GT-R, MR2 and DC2 Integra:
This Model A had a hot-rodded 4-cylinder Flathead. It’s a small world and through Geoff we were introduced to the owner, John B. John races a Jaguar Special with CSRG!
Thanks to everyone that came out. We hope you get to the Enjoy The Ride this year, let’s make 2021 amazing. DO IT IN A DATSUN!
Z Car Garage is proud to bring this record-setting 1970 Datsun 240Z Bonneville Salt Flat car back to life for our client Randy Jaffe. In 1976, a team of Nissan employees set out to break the land speed record for the stock body F/GT class. They built this Z in their spare time, setting a new record at Bonneville of 166.037 mph which stood for almost a decade. A monumental achievement considering they had no factory parts support.
Join us as we revive this historically-significant Z from its slumber with chassis and engine work. We will also look at the story behind the Salt Flat program, with an exclusive account from Bonneville crew member and former Nissan Parts Manager Tom O’Connor.
History and Acquisition
This Datsun 240z set the F/GT class record of 166.037 mph at Bonneville with Nissan USA field engineer Bob Stockman behind the wheel. The old record of 153 mph was held by a Mercedes 300SL. Datsun actually set several records at Bonneville prior to ’76, starting in 1974 with a B-210 Hatchback (121.8mph, driver Mike Jones) and twice in 1975 with a 280Z 2+2 (164.3 mph, driver Milan Micka) and 164.6 mph with Nissan Competition Department head Tom O’Connor.
A team of six Nissan USA employees, working in the Nissan Technical Center, Competition Department and Service Departments built the F/GT 240Z. From left to right: Frank Honsowitz, Matt Bornyasz, Milan Micka, Tom O’Connor, Bob Whitehead and Bob Stockman. O’Connor was responsible for building the engine, Micka worked on the suspension and created the paint scheme and graphics. Bob Whitehead, National Service Manager, was the man who originated the Bonneville idea at Nissan USA in 1974. Check out the period, Nissan Employee Newsletter chronicling the Bonneville efforts (PDF) by clicking on this link.
Bonneville-As Remembered by Tom O’Connor
How did they do it? We reached out to Bonneville crew member and driver Tom O’Connor to gain insight. The team volunteered time after-hours to build the cars and successfully run them. Tom was a Nissan Parts Manager and also built all of the Bonneville racing engines…their success depended on his skills/knowledge and we thank Tom for this exclusive, first-hand account of the F/GT record-setting effort.
Bonneville 1974, 1975, 1976 – As remembered by Tom O’Connor
“The story of the record breaking 240Z in the F/GT class at Bonneville in 1976 really began in 1974. Bob Whitehead the VP of the Technical Engineering and Service Support, a hot rodder and Bonneville fan, approached the employees in his department with the idea of running a Datsun B210 at Bonneville. Several of the employees including myself were currently SCCA club racers and we were all ecstatic about building and racing cars without having to spend our own money. We would have to work on the project after hours but the Datsun Technical Center facility was at our disposal and somehow Bob hid our expenses in his budget. The B210 went 121.8 MPH capturing the I Production class record.”
“After this first trip to Bonneville the team realized that it was harder to go fast at Bonneville than we thought. It’s over four thousand feet elevation, the salt and skinny Bonneville tires makes it difficult to get traction, and you only have two miles to get up to speed before entering the timed third mile. If you can go over 200 MPH on the three mile “short course” you can then use the five mile course for your record run. After considering all of this and looking at what classes the Datsun cars could fit into, we came up with the ambitious plan to return the following year with a 280Z 2+2 that was allowed to run as a production car, not a GT car. The plan was to build two different engines, one that would fit into the G Production class and one that would fit into the F Production class. What made this plan so ambitious was that to make a record run you must qualify one day by running the course in one direction and break the existing record for the class. You then come back the next morning to make the official record breaking attempt. This time you run in both directions, the two runs are averaged thus eliminating any advantage or disadvantage a wind would give a one way run.”
“Our problem was the number of days available to make two record attempts. Luck was on our side and the weather was perfect, the car passed technical inspection and we went to work changing the engine so we could be back the following day to make our qualifying run for the second record attempt. I was fortunate enough to be the driver for the F Production record. The car was so stable and you are so far from any objects that the sensation of speed is not there, but I became a big believer in aerodynamics when I turned off the engine at 165 MPH and the car slows to 90 MPH in what seems like a second. I really realized how much power it takes to push the air. The 280Z 2+2 broke both the F and G Production records. 164.6 and 164.3 MPH”
As soon as they came home, the team started looking at what they would do in 1976. They realized the 240Z that Datsun had loaned to famous cam grinder Racer Brown in 1972 to break the F/GT class record was sitting in a warehouse. The red paint can still be seen under the current livery.
Tom recalls preparing the 1970 “Racer Brown” Z for the F/GT class:
“The engine we had built for the G Production class was also the correct displacement for the F/GT class. We installed a “G” nose, added a few tricks we had learned, put the distinctive stars paint job on the car and went back to Bonneville to claim our fourth record in three years. It was great fun and really showcased how much talent was in the Datsun Technical Center in the mid seventies. Some evenings we could have as many as ten guys working on different systems that required their particular talent. I think that it is telling that three of us on the team went on to careers in motorsports. Frank Honsowetz would became the Nissan Motorsports Manager, Max Jones would spend much of his career at Rousch Racing and then become the Competition Director at Ganassi Racing and yours truly would finish out his career as a Competition Manager at TRD. Bob Whitehead would move on to Subaru where he used the same model of using enthusiast employees to build cars that broke records. It was also great, back in the day, to have many old Bonneville racers be so open and generous with their encouragement and suggestions to a group of 20 year olds entering their world.”
Out of the numerous trophies that Tom and the Bonneville team of Nissan employees earned, this one stands out:
“Alvin, this is it!! The trophy from ’76 hung in my shop for years, I don’t even remember how I ended up with it. The plaque was given to each member of the team by Mr. Katayama. I have given these to Randy so they will stay with the car.”
Tom is doing well, and we even saw him at the 2021 Amelia Concours (details below). Here is Tom with his ’72 240 that he got as a Christmas gift from his wife. He is excited about Z Car Garage reviving the F/GT Datsun 240Z:
“Fast forward forty five years and I get a call from Randy Jaffe telling me he has acquired the F/GT Datsun 240Z and that he is going to restore it and add to his collection! What great news to have a guy like Randy decide that the car and its story is worth preserving.”
Acquiring a Legend
Randy Jaffe has built a few notable cars with Z Car Garage including the Rocketbunny Series1 240Z and #46 BRE Datsun 240Z driven by John Morton. We were stoked to hear that he was able to add the Salt Flat Z to his collection. Here is how it all happened:
“The record setting Z sat in the Nissan Heritage Museum from circa 1977 thru 2020 in a non running state. Of course all Z cars catch my eye – but this super low mileage (2329 miles) Series 1 car with a Nissan Comp G-Nose on it with records set in both 1972 and 1976 – well I drooled over it after visiting the Nissan facility in Nashville several times. The guys who run the Heritage Museum and I have a relationship so we were discussing several cars in their collection and they mentioned they may want to see that Z in my hands.”
Indeed, big thanks are in order for the great people running the Nissan Heritage Museum including Jonathan Buhler (Sr. Specialist Corporate Communications at Nissan) and industry veteran Dan Passe (Director, Corporate Communications). Both gentlemen are hardcore automotive enthusiasts (see Jonathan’s personal Datsun 240Z) that proudly wave the flag for Nissan. They also do it on a volunteer basis, much like the F/GT Datsun Bonneville team. Randy’s plans for this historic Z car:
“Of course my immediate plans were to get the car mechanically sound with a new race motor and aesthetically get the car as good as it can be! Not until I got the Z back to my shop did I realize after scrutinizing old photos with placed decals on the car that this was same Z raced at Bonneville by the famous cam grinder RACER BROWN out of Virginia where he set the record of 152+ MPH in an orange paint scheme that was still visible in certain places all of the car. I understand at one point the car was ordered to be crushed by Nissan but the Nissan Parts and Competition Team somehow skirted that issue, added the G-Nose, painted the car and put it back on the Flats in 1976 with the record that held up for 9 years.”
Z Car Garage Revival
Randy shipped the Z from Georgia to our shop in San Jose, CA where we were tasked with bringing it back from its 44-year slumber. We admired the many details throughout the car, all designed and implemented by that famed team of six Nissan employees. This is probably the lowest mileage (not sold to the public) S30 in existence with about 2300 miles on the chassis. Immediately we noticed how preserved and rust-free the chassis and bodywork was for being a Salt Flat racer.
As you may recall, the standard front nose was run in Racer Brown trim: The F/GT team added this prominent “Grande Nose” for improved high-speed aerodynamics:
The “G-nose” was a factory-made, 5-piece kit made for the JDM-only Fairlady ZG (HS30-H). Created for Group 4 racing, it became a dealer option so it was common to see the G-nose on JDM and export market S30s. Check out the stock ducting:
One might expect a full roll cage for a Z car destined to run 166mph…here the stripped interior houses a simple roll bar with integrated headrest. It gets better as the steering wheel and seats are straight from the uber-rare Fairlady Z432R (shown as reference below)!
Keen observers may note that the steering wheel is an “Ura Mach” unit. This leather/aluminum steering wheel was an available option to all S30s from Nissan sports/race, with the stock wheel being wood composite made by Izumi. Though available as optional parts, these seats and steering wheel were removed from a 432R and installed on the F/GT car as delivered from Japan by Nissan!
Chassis
With respect to the ultra-low mileage of this chassis and provenance we performed a “sympathetic” refresh to make it road-worthy. The entire suspension was removed and powdercoated, with all hardware re-plated. Before/after shots below with more in the gallery.
We rebuilt and replaced all factory brake components including new calipers, rear drums/shoes+wheel cylinders, new wheel bearings front and rear:
New drum brake components:
Freshly powdercoated suspension and undercoated chassis:
New tie-rods, rack bushings an engine mounts:
The tubes inside the original wheel/tire setup were replaced. We built another set of wheels with Vredstein Classic tires in stock size with Mooneyes covers for display.
Engine
Randy wanted to proudly display this historic vehicle in his collection, but more importantly (also why we love him), he wanted to drive it so people can see and hear the F/GT in action. The stock L24 wasn’t going to cut it, this Z was getting the Jaffe-treatment with a famous engine to give it some go…
“John Caldwell had just built us a back up race motor for the 46 Z and it was on an engine stand in my shop so I decided that would go in the Salt Flats Z. The original record setting motor was prepared by Tom O’Connor and his team at Nissan but was long gone. The original 1976 raced motor and the Caldwell motor both L28’s were built almost identical with 44mm Mikunis and very high compression so it would be back similar to its 1976 build. A motor was in the car when I got it but it was a 1973 L24 with flat top carbs and it was not plumbed up – just sitting in the engine bay. There was no question that the car would go immediately to Z Car Garage to receive its heart transplant along with an overall inspection to get the Z road worthy and running strong! Rob went thru the brakes, hydraulics and made sure the car was prepared to drive as if it was going back to Bonneville.”
We installed the Caldwell-built backup engine that was prepared for the BRE 240Z from The Mitty. Randy purchased a set of ph44 Mikuni’s from ZCG complete with Harada intake, velocity stacks, linkages and Z Car Garage Heat Shield. We tried to replicate as much as we could in the engine bay from period photos and history told by previous team members:
More drivetrain goodies. The exhaust system includes a ceramic-coated header and side/rear exit all painted white. The engine is backed by a low mileage 280zx close-ratio 5-speed from Rob’s stash of parts with a JWT aluminum flywheel ad HD clutch. Power is sent through an R180 with 4.11 gearset complete with new bearings and hardware:
New radiator hoses and cooling system refurbished. Notice the large hole in the driver’s side radiator support? This chassis was fitted with a Nissan race carb inlet ducting kit! The fuel system got some love as well with all new lines and refurbished fuel tank. More detailed photos in the gallery:
The fuel pump assembly was updated while remaining faithful to original system. Before/After:
We hid the hid the MSD box by building a bracket and running the wiring into the engine bay. Inside the cabin we cleaned up gauges and made everything functional:
A Museum Piece that Moves!
How does the reborn F/GT Salts Flat Z sound and feel to drive!? Randy loves it:
“With a 13.5+ compression L28 race motor and straight pipes – well it’s music to a motorsports guy. The car has such little mileage and had several tricks added by the Nissan team that it drives amazing and is a total visceral experience!”
Photographer and ZCG client Larry Chen visited us and did an in-depth look at the Z on Hoonigan Autofocus. We made this video below complete with a dyno run, driving on the street and a few clips to give you an idea of the Salt Flat Z experience, enjoy!
We asked F/GT team member Tom O’Connor what power the Z made to achieve 160mph+ at Bonneville:
“I don’t remember exactly but it was a little over 300. Frank Honsowetz and I have discussed it and he can’t remember either, but 300 was our goal and I remember we beat it. We also can’t remember what diff ratio we used but I remember spending a lot of time with the gear ratio/tire size speed calculators.”
Rob dyno-tuned the Caldwell-built BRE motor, making 254hp/212tq to the wheels, not far off from the 300hp mark of ’76 while making all the right noises! Don’t forget to watch the dyno run in the video above!
Salt Flat Z wins at Amelia Concours!
Z Car Garage finished reviving the F/GT Salt Flats car and shipped it back to Randy in Georgia, just in time for the Amelia Island Concours. This event, like many Concours gatherings are heavy on Euro/US entries with little Japanese classic representation. Randy mentioned the Z to the guys at Amelia and they accepted it!
“After that first call to Rob I tracked down Tom O’conner in the LA area and he was thrilled to know that the car may run again and was kind enough to take the winning plaques off of his garage wall that were there since 1976 and shipped them to me! I then was talking to guys at Amelia about the Z and they said immediately – we want the car on the grass in 2021. The event is usually in early March but was pushed out until early May because of the Covid restrictions. Tom O’conner and I spoke several times and he said he would like to attend the Concours with his wife Sharon. This was huge to me to reunite the team leader back in the day with this car!”
Indeed, it was great to see Tom reunited with the record-breaking Z he was part of.
Rob Fuller was also present, meeting several iconic racing legends like Trevor Harris and Peter Brock. Icing on the cake…Randy Jaffe won two awards!
What a sight to see (and hear) the Z on the grass of the Concours. Here is a video showing it in action and revving up to accept the award. Randy also talks a bit about the Z:
Thank You!
ZCG thanks Randy for his unwavering support. We love your passion Randy and how you wave the flag for Nissan/Datsun history. The Salt Flat Z is in great hands for the next generation to appreciate. Stay tuned readers as we feature another cool Z from Randy’s collection on zcarblog. LONG LIVE THE Z!
Z Car Garage is excited to collaborate with Datsunworks and develop their brilliant KN20 dual-overhead cam (DOHC) cylinder head designed for the Nissan inline-6 L-Series engine.
Datsunworks founder Derek Minetti is the pioneer behind the KN20 DOHC cylinder head. This is a custom (very limited production), 6-cylinder head derived from Honda’s venerable K-series 4-cylinder engine. The KN20 offers superior head flow rates combined with modern valvetrain components to effectively transform your L-series single-overhead cam into a high-revving, dual-overhead cam engine. The power potential is impressive.
Gary’s Datsun 240Z
There are ten KN20 heads in the wild with only three installed and currently running in cars. Z Car Garage has two KN20 cylinder heads. This KN20 is serial #SN10 and it has been installed into our long-time client Gary’s Datsun 240Z, affectionately named the “Behemoth”. ZCG is always exploring the boundaries of powertrains and Gary’s Z has seen a few engines including an RB30DET, OS Giken TC24 and now the Datsunworks.
Here are few details on the powertrain setup for this Z:
-Rebello 3.1L Engine
-KN20 Cylinder head SN10 (but the performance level goes to 11)
-Induction type: Jenvey ITB EFI with Injector Dynamics injectors
-Engine management: Haltech Elite 750
-Header: Equal-length, custom fabricated by RacecraftNW
Pictures of the initial engine installation, with more in the gallery:

Performance
We are still in the tuning phase so Gary’s car is on a comfortable (conservative) setting. With the Datsunworks head it made 350hp/248tq at the wheels on 91 octane:
Even in a testing stage it is absolutely thrilling to drive. Gary’s car is a full ZCG-style restoration so it has the chassis to harness the power. The sound it makes is a sonorous tone only the K-series derived KN20 head creates…with a gnarly exhaust note to match. The ITB induction also provides a healthy wail…it’s a sensory overload and revs seem to climb endlessly.
To illustrate the Datsunworks experience we captured some video of what it is like to drive around town…the 6-speed and EFI really allow this car to be docile, especially when cruising on the freeway and at part throttle. Drop a gear and its becomes a wild animal. Not going to lie…it gave me goosebumps both as a passenger and spectator.
Watch the video complete with multiple dyno passes, street acceleration and fly-bys. VOLUME UP!
Potential
Z Car Garage is stoked to be a part of the Datsunworks KN20 development. It is a clever design that pushes the envelope for L-Series engines. Sharing this experience is also part of the fun so we anticipate having a KN20 setup in a dedicated shop 240Z for clients to test drive and further evaluate. Although each application is different, we envision offering a bolt-in setup for your six-cylinder L-Series engine. The power potential is tremendous with the KN20…both NA and forced induction. We thank Derek at Datsunworks for giving us the opportunity to work with this innovative product.
Stay tune for more updates and LONG LIVE THE (TWIN CAM) Z!
