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 AxlesZ 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:

 

 

Khang loves the ZCG Big-Brakes:

“They are a must have and definitely allows the bigger power. Kind of spoiled actually. I’ve recently checked out another 240z and drove it and then hit the brakes and forgot that they were stock and almost ran through a stop sign.”

Engine Bay Services

Khang’s engine bay was painted black so we took this opportunity to paint it body color and perform re-installing the new engine. As usual William worked his magic to apply the white paint while we zinc’d or powdercoated all parts in the engine bay. The before/after is dramatic, no doubt from the new engine discussed below!

 
 
 

New hydraulic lines/plumbing and wiring harness with general cleanup made this engine bay pop:

 

Engine

 

After a year of enjoyment Khang desired more power. We installed a Rebello 3.2L engine with upgraded cam, Harada intake and Jenvey fuel injection. The old SU-fed L-series was removed:

 

We knew the car would be stopping and handling better than before, so we installed a Moroso oil pan and Koyo aluminum radiator to keep temperatures in check. We are using Pacesetter 3 into 2 header ( to clear six-speed) leading to our ZCG exhaust system with stainless resonator and slash-cut tip.

 
 

Jenvey Fuel Injection

We are huge fans of modern fuel injection on the L-series for it ease of operation, excellent hot/cold start behavior, tuning abilities and all-around driver-friendliness. Khang’s 3.2L engine uses an individual throttle-body induction setup from Jenvey. We have used this setup on several builds, including Scott’s 260Z with stellar results.

 

In-progress shots of the throttle body wiring. We mounted the ignition coil on the firewall to minimize clutter. The valve cover was also changed.

 

The fuel injection system is run by a Haltech Elite 750.  The ECU was mounted in the passenger side footwell:

 

Topping the ITBs off are custom, merged mesh air filters. The sound from the Jenvey EFI is intoxicating. More pictures in the photo gallery!

 

We also installed what every L-series needs: a Z Car Garage Heat Shield!

 

Fueling mods to support fuel injection including in-tank fuel pump. The tank was pulled and boiled out/refurbished before adding EFI:

 

Dyno Tuning

Rob dyno tuned the 3.2L via Haltech.  Baseline was 129hp/131tq with the old engine and with Rob’s tuning the 3.2L made 264hp/231tq at the wheels. Watch the dyno run and listen to those Jenvey ITBs scream in the video below!

 

Beyond performance, Khang is very happy with the Jenvey EFI:

“Best thing I can say is I don’t plan to ever go back to a carb setup again. Knowing that it’ll turn on every time and can be on the road for prolong periods of time without feeling like I need a gas mask on. Carbs were tolerable when I was younger but now a days I like the comfort features of EFI.

Driveline Upgrades

We built Khang an R180 rear diff with 4.11 OS Giken LSD, a perfect upgrade for anyone doing spirited driving. All built in-house with new bearings/hardware by our very own Joshua Corwin:

 
  
   
 

The clutch hydraulics were replaced to work with new aluminum flywheel/JWT HD clutch combo:

 

Six Speed Transmission

Next on the update list, we were really excited to install a Nissan 350z 6-speed manual transmission behind the L-series in Khang’s Z. You read that right! S30 owners can now bolt-in this robust, 6-speed manual behind their L-series engine! You might remember our first application of Austin Hoke’s custom 6-speed adapter kit on the OS Giken TC24B1Z-powered 240z, Trevor’s 280Z and Frank’s 240Z:

 
 

Using the 6-speed conversion kit from Hoke Performance we installed a new CD009a transmission from the 2003 -2008 Z33 in Khang’s 240Z:

 
 

Here is the brand-new transmission from Nissan being unboxed:

 

 

The kit necessitated exhaust header changes and after testing a variety of headers we found the Pacesetter 3-2 unit provided enough clearance. Serial 9 provided the shifter relocation assembly and we are really happy with its performance. Also shown is the aluminum driveshaft.

 
 

It fits! More installation pictures in the gallery.

 

It’s a very discreet look from the cockpit…until you feel the amazingly direct and precise feel of the CD009a!

 

Khang is in love with the six-speed, we are as well:

The CD009 Gives the Z such a more modern feel but still plenty of fun at the same time. Retains the rawness but then put it into 6th gear and it cruises like a modern day car. Love the shift knob.”

Enjoy this video of the Z in action with dyno runs, engine and exhaust revs, freeway cruising and acceleration:

Z Car Garage CV Axles

Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. We have over 140 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 
 

Stock half shafts (L) and ZCG units:

 

ZCG CV Axles installed on Khang’s 240Z shown below with more pictures in the gallery:

 
 

Panasport Wheels

We are an authorized Panasport dealer and lover. Khang’s meshies were replaced with 16×7 Panasports and 225/50/16  Yokohama S-drive tires followed by a full alignment:

 

Details

 
 

We sorted out little things for Khang that make a huge improvement in Enjoying The Ride. One item we are particularly proud of is this custom, OEM-like shift knob displaying a 6-speed shift pattern. Khang is one of the first customers (other than the Behemoth and Butters) to receive this cool shift knob that emulates the factory 4-speed shift pattern and font:

 

The speedo and tach are functional with a GPS box and tach adapter:

 

The interior was treated to a new set of Recaro Specialist seats and our ZCG sound deadening program to eliminate that “tinny” sound.

 

More small details like replacing all coolant and fuel hoses, breather, new battery and cables:

 

Driving is Believing

 

When Khang picked up car earlier this year, he was blown away:

“I’ve had several Z’s over the years. I had a green ’75 280z for about 10 years throughout college and had it worked on by Rob at one point. Sold the car and then just missed it too much and literally bought my current 73 240z about 6 months later in May of 26, 2017 as shown in the picture when I went to pick it up. I knew from my previous experience with Z Car Garage that I wanted Rob to build this new one for me.

 Thank you Khang for allowing us to build you a 50 year old supercar.  We are so fortunate to work with owners that appreciate the Z and believe in our ability to make them better! LONG LIVE THE Z!

STOLEN: Z Car Garage Vintage Trailer-please be on the lookout

Filed under: Featured Cars and Projects
by Alvin G @ 11:07 am on October 16, 2021

 

BE ON THE LOOKOUT!!!
Our trailer was stolen last night in San Jose, CA. Please share and contact us immediately if spotted. License plate# 4LA8323 Thank you!
**photo with car for reference: just the trailer was stolen, luckily not the race car**

 

 

UPDATE: Video surveillance shows a black First-gen Cadillac Escalade SUV taking the trailer at 4:11am. It was a single person with a white hat and he broke our trailer lock to hitch his Escalade up. Please spread the word.

 

 






 

To appreciate the 1991 Aztec Red 300ZX Twin Turbo pictured above we must tell you a story of love, heartbreak, persistance and ultimately satisfaction. Z Car Garage client Jas D has been with us since 2014 when we helped build his 1990 Nissan 300ZX Twin Turbo. This Super White, 44k original-mile example was treated with all the ZCG touches that make a Z32TT go from wonderful to extraordinary. We dubbed it the “Z Masterpiece” (see more here) as it embodied the total package: Power. Handling. Braking. Aesthetics:

ZCG 82514 CAM 4 087
CAM 2 103114 203 Cam 3 103114 012
 

Jas totally Enjoyed The Ride in this Z, adding 28k thrilling miles with ZCG maintaining it over the years:

“My brother and I have been ZCG customers for almost a decade. I met Rob when I called about getting a PPI on what became Z Masterpiece. At the time, a Super White manual came up on AutoTrader (I LOVE Super White-OMG). It was a low-mile, one-owner, meticulously-maintained time-capsule. Rob actually said WOW after the PPI, and we worked with ZCG over a couple years on a few iterations until we got Z Masterpiece. That car was perfect!  My dream Z; I loved driving that car EVERYWHERE! It is probably my favorite car of all time!”

ZCG CAM4 71314 033 IMG_1615 
 

Unfortunately, in 2016 the Z was stolen.

“On October 29, 2016, Z Masterpiece was stolen. We cried, we laughed, we got angry, we sulked for a couple months, forgot about it, and then my dad found the car driving into SF on January 25, 2017. The car had clearly been driven like it was stolen. But, believe it or not, all the expensive components were still on there. We sent it to Rob right away, and he helped us turn Z Masterpiece into the Red Devil Z (which I purchased on April 20, 2017 with 66,XXX miles).”

From Z Masterpiece to Red Devil

 

Persistance paid off, and Jas found a really clean Aztec Red ’91 Z32TT with only 66k miles. All of the upgrades from the Super White, Z Masterpiece were transferred over:

“Rob pulled the motor from the Super White, re-did all the seals/gaskets, and then put the driveline back together into the red Z32TT.  Coincidentally, both cars and engines had 66,XXX miles when this was done in summer 2017.”

 

 

Let’s take a look at the modifications that turn the already stellar Nissan 300ZX Twin Turbo into a superb, balanced sports car.

Engine

 

Though bone-stock with an amazing 44k miles on the clock it needed some attention. We went through the hydraulics and performed full 60k-mile services.

ZCG CAM4 71314 048 ZCG CAM4 71314 043 ZCG CAM4 71314 052
 

Jas wanted to improve power and handling and we happily obliged with a comprehensive list of upgrades this year.  Starting with the drivetrain, the original transmission was replaced with a brand new(!) unit from Nissan:

ZCG CAM4 71314 100 ZCG CAM4 71314 104 ZCG CAM4 71314 102
 

The clutch had seen better days so we replaced it with a JWT unit including their heavy duty aluminum flywheel:

ZCG CAM4 71314 061 ZCG CAM4 71314 099 ZCG CAM4 71314 098
 

A JWT ecu w/boost jets manages uprated NISMO 740cc injectors and the Selin dual MAF. Improved breathing comes from Ash-SPEC inlet piping and dual JWT pop chargers:

Cam 3 103114 007  
ZCG 82514 CAM 4 037 ZCG 82514 CAM 4 047 ZCG 82514 CAM 4 051
 

On the exhaust side, restrictive original downpipes were replaced with these beautiful Specialty Z 3″ downpipes. Note the divorced wastegate piping:

ZCG CAM4 71314 070 ZCG CAM4 71314 091
ZCG CAM4 71314 064 ZCG CAM4 71314 094
 

Following the new downpipes are more parts from SPZ including 3″ mid-pipes and a cat-back exhaust system to replace the OEM setup:

ZCG 82514 CAM 4 009 ZCG 82514 CAM 4 005 - Copy
 

OEM vs SPZ:

ZCG CAM4 71314 055 ZCG CAM4 71314 056
ZCG 82514 CAM 4 007 - Copy ZCG 82514 CAM 4 014
 

More upgrades. We installed 4.08 Leader gears, Ash-SPEC Massive SMICs, 2.5 IC tubing, and  SPZ Hi-5 upgraded clutch. The BDE low-profile Z32 motor mounts are a smart alternative to OEM that allows more clearance larger for intakes:

CAM 2 103114 141 CAM 2 103114 142 
Cam 3 103114 006 ZCG CAM4 71314 079 ZCG CAM4 71314 087
 

Rob recently dyno-tuned the red Z, making 353hp/353tq to the wheels on 91 octane:

 

Stoptech Big-Brakes

 

With all of the speed parts installed next we tackled chassis improvements. Let’s begin with brakes followed by suspension:

ZCG 82514 CAM 4 061

We love Stoptech’s products and use them on our own vehicles.  Z32s are relatively heavy and with higher hp the stock caliper/rotors can be taxed quite easily. Jas took it up a notch and ordered a Stoptech 4-wheel Big-Brake Kit for his beloved Z.  Shown above is the ST40 caliper (front) squeezing 332 mm rotors and at the rear are ST22s on 328mm rotors.

The installation:

ZCG 82514 CAM 4 060 ZCG 82514 CAM 4 080
ZCG 82514 CAM 4 071 ZCG 82514 CAM 4 092
 

Yes, they are pretty but also very functional. Speaking of aesthetics (that are functional, too), the new calipers are nicely framed between the spokes of these sweet VOLK TE37SL wheels, finished in bronze and sized 18×9.5/10.5 in high-pad offset with center caps.  We like your taste, Jas.  The lightweight TE’s were wrapped in Yokohama tires:

 

Suspension

The suspension was gone through completely with all new parts. KW V3s are our favorite coil-over setup, replacing the Stance coil-overs that the Super White Z had. Stillen sway bars are also shown:

 

Stock vs KW V3s installed front:

 
 

Rear:

 
 

Every little nook and cranny of the suspension was handled. New SPL tension rods, upper front control arms, new rear wheel bearings and HICAS removal/eliminator:

 
 

T/C rods, Stillen sway bar, we also replaced the rack bushings:

 

The Z looks great!

 
 

The interior is in great condition as well:

 
 

Jas and his brother love the Z. Thanks for letting us be a part of your journey!

“The Red Devil Z is vicious and so fun to drive. It is the quintessential 1990s Japanese sports car  – red – gold wheels – TTs – exhaust.  It goes fast. It stops fast. It turns fast. Z32TTs are the BEST! We love and respect Rob and the team at ZCG. Rob is a total big brother. He and the team have been with us through the passion and pain.”

**This Red Z32TT is for sale on Bring a Trailer!**

 

The quest for the perfect Z is almost complete as Jas just found one of the cleanest Super White z32s on Earth. That means the red car is for sale! Jas is listing it on Bring a Trailer. We will update this post and social media when the auction goes live so you don’t miss out! For now, enjoy the extensive photo gallery below, and LONG LIVE THE Z!

HISTORY: 1970 Datsun 240Z Salt Flat Racer Lives!

Filed under: 240z,Automotive History,Events,Racing
by Alvin G @ 5:10 pm on October 1, 2021

 

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.

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!
