Our client Randy Jaffe is selling his 1972 Datsun 240Z. This is a one owner, low mileage and very original example.
See more photos and video on our FOR SALE page. You can also see it in person this Sunday, June 11 as we drive from San Jose to the ZONC Blackhawk Gathering.
At Z Car Garage we are fortunate to be a part of our client’s sports car journeys. We first met Derek Y in 2014 when we worked on his 2005 Infiniti G35 back. A few years passed by and he visited us with his latest Nissan, this 2015 GT-R:
The R35 had only 11k miles and ZCG installed a host of power upgrades from AMS, EcuTek, SpecialtyZ, Turbosmart and more. You can read about this work from 2019, including the E85 flex-fuel and exhaust upgrades all in this previous blog post.
Derek latest visit was earlier this year for dyno tuning, interior items and AirLift installation. When it arrived at the shop this R35 sported a complete Varis Kamikaze-R Ver. 2 widebody “Super Sonic” kit and Varis Kamikaze-R Ver. 2 Vented Carbon hood. The Air Lift 3H air suspension strut kit was installed with polished 5 gallon tank.
We ran all of the air lines, checked ride height and clearances for the slick Advan R6 Candy Red wheels (20×11 +15 front – 20×12+20 rear) with Toyo R888R tires (305/35/20 Front – 325/30/20 Rear), more installation photos in the gallery below:
We also installed a new, Overtake 100-V Saikou Exhaust:
A few minor items like a new battery, TPMS sensors in the new wheels and a final health check for Derek’s VR30DETT…but first we performed a re-tune with Ecutek for even more power. Our last dyno session yielded 612hp/604tq to the wheels and it left with 640hp/622tq. What’s impressive is that this remains a supercar that’s easy to to drive:
Enjoy these dyno runs:
Derek had several interior items for us to install including: Mines Steering Wheel, Nismo Cluster, Nismo cluster shroud and shiftter paddles:
Derek is happy with the latest upgrades to the R35:
“I have been going to Rob for a while now, he worked on my car october 2019 (bolt on and e85 work done) and again recently with a new tune and air suspension and some interior mods. The work is always great its making more power now and more responsive linear power.”
Here are the SpecialtyZ 3″ intakes and AMS front-mount intercooler being installed:
More engine bay work including the AMS crankcase breather setup, ID 1300cc injectors (plus DW fuel pump upgrade), Turbosmart BOVs and a SpecialtyZ Flex-Fuel kit:
AMS crankcase breather being plumbed:
Stock vs Turbosmart BOV:
On the lift, AMS cat-less downpipes are installed:
At first glance it is difficult to catch all of the power upgrades in the engine bay, Stock (L) vs Modified (R)
Derek also needed new tires so we mounted fresh Michelin Pilot Sport4S sized 245/40/20 and 285/35/ 20.
Back in 2019 , Rob dyno tuned the GT-R using an EcuTek flash and Derek also received a USB dongle for datalogging. Baseline power was 495hp/446tq with final numbers of 612hp/604tq to the wheels on E85:
A few plots showing the tuning session: Baseline to 91 octane tune with gains of 65hp/93tq (Left), and the final E85 tune for even more gains of 52hp/51tq (Right):

Thanks for letting us work on your GT-R Derek and enjoy the boost!
Last week the Brock Racing Enterprises (BRE) Datsun 510 #46 race car arrived at Z Car Garage. Despite being against all odds, our hero John Morton drove this 510 to SCCA Trans-Am series championship victories in 1971 and 1972, putting Nissan on the map and fueling every Datsun enthusiast’s passion. In preparation for this weekend’s Velocity Invitational at Laguna Seca we dyno tested this legendary race car. Turn those speakers up and enjoy the video!
Huge thanks to Nissan and Randy Jaffe for giving us the opportunity to prepare the car. It was surreal to have it in our shop:
We spent hours admiring and pouring over all the details on this historical 510. Note the swirl chamber, BRE exhaust header, oiling system and hydraulics:
The chassis reveals hard-earned battle scars:
Note original Koni shocks, Porsche 911S calipers and oval section of exhaust, more photos in the gallery below:
Z Car Garage is really proud to announce special guests (and our heroes) John Morton and Pete Brock will be at the Velocity Invitational on Friday and Saturday. This is a rare opportunity to get an autograph and chat with these iconic gentlemen.
To celebrate the 50th Anniversary of the Trans Am (under 2.5) racing series, Z Car Garage coordinated with Nissan Corporate to have the original BRE Datsun 510 displayed with the Horst Kwech Alfa Romeo at the Velocity Invitational. See the actual race cars in person, only at the Velocity event!
See you this weekend at Laguna Seca!
We had a great time enjoying the 2023 Nissan Z during Monterey Car Week. Thanks to Nissan, we got to enjoy driving the Z to several special events and dyno test it at our shop. Let’s get straight to the numbers!
This is the Performance model in Two-Tone Ikazuchi Yellow TriCoat / Super Black and 9-speed automatic. In stock form and 91 octane it put down 345hp/362tq to the wheels. The dyno plot below shows dyno results from the Yellow automatic Z and the Passion Red 6-speed manual Z we dyno tested in June. Super excited to tune the new Z and unlock more power!
Enjoy this video of the dyno runs, road testing and exhaust sounds.Volume up!
Note, this automatic model has a different exhaust system than the manual model.
Huge thanks to Nissan for lending us the Z to enjoy during Monterey Car Week. Here is our coverage if you missed it

Stay tuned for more exciting news about the new Nissan Z and Z Car Garage. LONG LIVE THE Z!
Z Car Garage specializes in dyno tuning vintage cars. Our in-house dyno and expertise in carb tuning can help your engine reach its potential whether it is a street car or full race car. We love Datsun roadsters and recently dyno tuned Erik’s 1970 1600 with great results. Let’s take a look at how he got into Datsuns…
Affectionately named “Audrey”, Erik bought this 1970 Datsun Sports 1600 in 1995 and drove her every day while living in San Jose and Santa Monica, CA. He had lots of adventures in those days, including driving on Highway 1, Route 66, and even blowing a head gasket in the desert outside Needles, CA.
“In 1998 he got a job in Thailand and Audrey was put in storage. Stored outside for years, she suffered the indignity of being broken into and vandalized. (I’m still apologizing to her for that.)In 2000, I moved back to the USA, but had no garage for Audrey, so she remained outside, staying with friends and family. By 2003 she had finally moved inside, but a busy life and no shop space meant that she sat in the corner, patiently awaiting resurrection.”
“Fast forward to 2019: now having a great garage space and some free time, it was time to get Audrey back on the road. On the outside, she still wears most of what’s left of her original 52 year old paint, but inside and underneath it’s a different story: Her factory 96 horsepower has been doubled using the original engine, and her 4 speed transmission has been swapped for a 5 speed. The body was removed from the frame, all suspension, steering, and brakes were redone/upgraded, all electrical wiring replaced, every nut and bolt was either re-plated or replaced, and the interior restoration has begun, slowly changing from black to red.”
“Since then, Rob has been super helpful while I’ve been restoring my 1970 Datsun 1600 from connecting me with the engine and transmission rebuilders, to helping with parts restoration, zinc plating, advice, and moral support. Once I had the car assembled and the new engine broken in, I knew I wanted to get it tuned on the ZCG dyno.”
Erik’s roadster is a “1600” model, originally sporting 1.6L (R16) with dual-SU induction and 4-speed drivetrain. His restoration included stroking the original motor to a larger 2150cc displacement with twin-Mikuni induction and 5-speed (u20) transmission. You can learn more about Erik’s restoration efforts and the Rebello stroker R16 drivetrain all on 311s.org HERE.
Our initial dyno tuning session was with Phh40 Mikuni carbs. While it made great power Rob had always suggested running a larger Phh44 carbs to take advantage of the stout Rebello cam. Erik returned for another dyno session. With the carb switch, A/F ratio and timing optimized the roadster put down an impressive 157hp/151tq to the wheels with improved driveability throughout the entire rev range:
Erik was stoked with the tuning results:
“After finding some compatibility issues with my carburetors, Rob helped me build and install bigger carbs (the ones Rob had told me to use all along!). Came back for another tuning session and wow – what a difference. More power everywhere, better idle and driveability, and top end power is phenomenal. Many thanks to Rob and the whole Z Car Garage crew for taking my car from good to amazing!”

Datsuns Are Driven! In true roadster fashion, Erik has been Enjoying the Ride in his revived “Audrey”. We got the roadster prepped for a 600+ mile road trip to the Annual Datsun Roadster Meet at Mt. Shasta back in June. The car ran flawlessly:
Erik has been attending local car shows and rallys including VALT Car show in Berkeley, CA and Breakfast Club Rally.
We had fun tuning Erik’s roadster and getting it dialed in with the new drivetrain. Eventually it will be time for bodywork and paint, but he’s too busy having fun on the road! Thanks for letting us be a part of your Datsun journey Erik, you’ve done the roadster justice! If you have a vintage car (it doesn’t have to be a Datsun) feel free to contact the shop to schedule a dyno tuning session. More photos in the gallery below.
