Khang D is from Modesto and we first met him in 2012 when he visited Z Car Garage with a green 1975 Datsun 280z. We serviced the car, fixed several items and he enjoyed it for a few years before selling. In 2017, Khang purchased this white 1973 240z from our client Brent B, and returned to ZCG for full suspension upgrades including Z Car Garage Big-Brakes, new OEM mirrors, Panasport wheels and a complete tuneup.

 

It wasn’t long before Khang came back to ZCG with a request for more power to match the excellent chassis improvements. Let’s take a closer look at this fantastic daily driver+canyon carver showcasing our  Z Car Garage CV Axles, Z Car Garage Heat Shield, Jenvey ITB fuel injection, CD009 Six-speed transmission and more.

Suspension

 

In September 2017 we overhauled the suspension. The Z received coil-overs from Techno Toy Tuning including T/C rods and rear control arms. The entire front suspension was re-done with new bushings, wheel bearings, rack bushings, steering coupler, etc.

Struts, OEM T/C rods replaced with coil-overs:

ZCG Big-Brakes

“WOW, what a difference. The feel, modulation, power, sharpness was amazing. Hands down the best brakes I had ever driven on a Z car” -Glenn

As fellow racer Glenn C mentioned in his review, on top of braking performance, pedal feel is extremely important and our Big-Brakes deliver. This is a direct result of working with Stoptech to create a totally bolt-in solution requiring no master cylinder change or additional proportioning valve/adjustments, etc. All fitting behind a 15″ Watanabe or Panasport wheel (and some 14″ wheels) and retaining factory emergency brake lever! A few details below:

  

Calipers: Stoptech ST42 4-piston front & rear race calipers (Alum 6061 mil-spec Type III anodized)

Rotors: 280mm x 20.6 with Alum 7075 hats

Pads: Stoptech 309 sport street pads

Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE.

A few closer detail shots of the calipers, rotors and hardware:

  

Khang’s S30 got the full 4-wheel brake kit with new OEM Master Cylinder:

 

We also installed the fully functioning parking brake that works with factory linkage/handle:

Bring your friends, family and please spread the word. 

 

ZCG will also have several vintage Z cars on display to celebrate the lineage. A representative from Nissan will be present to answer your questions and this is a perfect opportunity for photography of the new Z. Big thanks to Larry Chen for sharing these photos with us.

 

We know this is a busy time of the year so mark your calendars for 10/23 to spend some time with the new Z! More details to follow (like parking suggestions) with updates on our social media outlets including Instagram, Facebook and here on zcarblog.com.

 

Huge thanks to  Nissan for making Z Car Garage the premier venue for sharing the new Z. It really gives us some 2008 vibes when our shop was chosen to host the first stop on the “Follow The Z” Tour of the then-new 2009 Nissan 370Z:

 

Long Live The Z!

 

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.

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.”

 

“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!

Jay M purchased a set of Panasport Wheels from Z Car Garage and recently shared his Z story with us. We are an authorized Panasport dealer and have limited sets available for fitment on your S30 Z car. Before we show you how a set of these 16×7 wheels look on almost every Z color imaginable, let’s hear about Jay’s 240Z…

“The car was from California and made its way to Gainesville FL and was put in storage.I had been looking for a good 240 and this one was taken by the owner to a shop owned by a friend of a friend.The guy wanted to get it running and sell it.  That triggered a phone call to me while on a anniversary trip with my wife to Italy, we were living in St Augustine Florida at the time.  My buddy sent me some pics and a quick video and he grabbed the car for me.  It was all there and very little rust. I had not really considered a Blue one, much less one with white interior.”

The car was restored by Jay and 3 friends minus paint and the head work in his 2 car garage over 3 years. Jay has met so many people in the Z community and learned much about Z cars:

 

Beautiful engine bay with new engine:

Check out the before/after on the interior…great work Jay and friends!

  

Jay recalls how he found ZCG and eventually purchased a set of Panasports from us:

“I found the on Z Car Garage videos on YouTube very early on which led me to your website.  I went to Daytona to see Randy Jaffe’s #46 BRE 240z car run and left just before John rolled it. I met Rob at the Amelia Concours earlier this year and bought a set of Panasports from the shop. I also have become friends and an Insurance client of Jim Frederick in Lutz Florida who I believe has the finest collection of low VIN original Z’s in the World!  Jim has also helped me with parts and advice on this build.  I am hoping Larry Chen will make it down to film Jim’s collection.”

 

The Panasports do look fantastic on this #115 Metallic Blue 240Z. Thank you for your support Jay, glad you are Enjoying The Ride!

 We met Vince M in 2019 when he was looking for a shop to take care of his 1972 Datsun 240Z. Vince’s goal for this Persimmon Red (#110) S30 was to have a reliable weekend driver and replace the cracked dashboard he grew tired of looking at. We installed a new dash from Vintage Dashes, sorted all ducting and installed new Z Therapy SU carbs.

 

Z Car Garage specializes in restoring and maintaining the S30 Z car. We love stock examples like Vince’s just as much as modified cars. Vince contacted us and patiently waited in the queue to get his Z at the shop:

“Searching online for someone that I could trust to repair my Z, I came upon rave reviews from other owners of Rob at Z Car Garage and reached out to him. Rob asked that I email him pictures of my car, particularly the engine compartment, to determine if he could help me, and within 5 minutes, Rob called me back. I immediately recognized that I found someone who not only supremely understands Datsuns, but also shared my enthusiasm and passion for keeping my Z on the road.”

 

Z History

Vince’s Z Journey began when he first started driving in 1974:

“Our High School P.E. teacher doubled as our driving instructor, and while we were learning to drive Dodge Monaco Sedans, his daily driver was a 112 Yellow (Lime) ‘73 240z. I asked him what he thought of his car, and he responded: “It’s the best car I have ever owned.” That’s all I needed to hear, and soon found myself at the local Datsun dealership in Millbrae California. There on the lot was a ‘72 240z, 4-speed, white on red, with only 33,000 miles on the clock. The dealer reluctantly took me out for a test drive and this 15-year-old was forever hooked. Great styling, smooth power delivery, a flawless gearbox and only two seats, which thankfully guaranteed that my car would NOT be chosen to endlessly cruise with my buddies on Friday’s and Saturday’s, usually ending with an interior filled with spilled drinks and food.”

 

Vince has since owned 300 different cars, but there has always been a Z in his life. His current Z is a ‘72 240z, 4-speed, 110 Persimmon Red, white interior, acquired 5 years ago, with a California only history. The car had a cracked dash with a glued-on cover, a clock that did not work  and original carburetors that badly bogged down while accelerating. It was time to get Vince back on the road.

New Dashboard

 

We removed the old dash assembly and performed clean-up work in preparation for the new Vintage Dashes unit. More pictures of the process in the photo gallery!

   

The heater box was refurbished with new heat/defrost vents, gaskets and all HVAC cable controls were lubed:

 

Ducting and completed heater going back in:

 

Since the dash was out we had access to the heater core which got pressure tested and serviced. All coolant hoses under the dash and in engine bay were replaced:

 

 

Every single bolt was replaced in the dash and the gauges refreshed. The clock was replaced and functions perfectly.

 

The completed Vintage Dashes dashboard and assembly ready to go back into Vince’s Z:

Dash install complete:

Vince is really happy with the new dash installation:

“As for my dash, I had several options but settled on a newly manufactured replacement dash from Vintage Dashes, minimizing downtime, and allowing me to keep my old dash in case I wanted to restore it. I trusted ZCG to take apart my entire dash and EVERYTHING connected to it. The result is a dash that looks like new (because it is) and everything connected to it working properly, including the clock, which by the way keeps excellent time.”

 

Engine Bay

 

A new set of SU carbs from Z-Therapy were installed along with all new fuel hoses and fuel filter:

 

Enjoy the Ride!

Vince is a great guy and a great Z car owner. He made this video showing his Z after the work ZCG performed, enjoy!

We love making our clients happy:

“My goal for this car was quite simple, I wanted a 1970’s time machine that I can use as a weekend driver, with the operative word being “use”, because in my humble opinion, Z’s are meant to be driven. Except for the carbs, the car was mechanically sound, but I wanted it to run like it should. I was also tired of looking at the dash cap, and wanted to have everything in working order, like it did in the 70’s, including the clock…”

“…In fact, everything works and runs so flawlessly, my car with 92,000 miles runs better than the 3-year- old Z I drove off the dealer lot back in 1974, a testament to Rob and ZCG. It feels good to be back in the 70’s, even if only on weekends. Thanks Rob, and long live the Z.”

Thank you for your support Vince, and yes, LONG LIVE THE Z!
