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…

Roadster Beginnings

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.”

Erik and Z Car Garage

“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.”

Dyno Tuning

 

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!”

Enjoying The Ride

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.

As Monterey Car Week approaches we are reminded of our time spent with the 2023 Nissan Z in June. Thanks to Nissan, we got to enjoy driving the Z on our favorite back roads and dyno test it at our shop. Part of the fun also included test fitting some aftermarket wheels and checking out the weight distribution. Let’s get straight to the numbers!

Power and chassis

In stock form with 91 octane the new Z made 379hp/375tq at the wheels. With a splash of 100 octane we saw gains of almost 10hp at the wheels. Super excited to tune the new Z and unlock more power!

Enjoy this video of the Z on our dyno:

We placed the Z on scales to get curb weight. It was 3455lbs:

Wheels Make the Car

Like previous generations, the new Z is blessed with some of the coolest OEM wheel designs. The aftermarket however makes it exciting to personalize our Z cars with the coolest wheels. We had to test fit some timeless VOLK TE37 Ultra Track Edition 2 and Work Emotion CR2P wheels, both sized in 19″ fitment:

WORK Emotion CR2P:

Big thanks to our  generous clients the Henry and Frank(feature soon) for donating these for the cause! More photos in the gallery below.

The New Z at Monterey Car Week!

Z Car Garage is excited and honored to attend the famous Monterey Car Week with the new 2023 Nissan Z!  Huge thanks to Nissan for giving us yet another opportunity to share this sports car with the world at a very prestigious event. On 8/17 we will be driving the Z to the official kick-off party at the Motorlux (formerly McCall’s Motorworks Revival) event. The Z will join vintage and classic cars to be displayed at the famed Pebble Beach Concours d’Elegance.

Later in the week, we will be showing the new Z at Laguna Seca during the Rolex Monterey Motorsports Reunion on Friday and Saturday. If you are catching the race action be sure to stop by the paddock where Racecraft is to say hello to us and the new Z!

Thanks again Nissan and LONG LIVE THE Z!

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 April.

WE LOVE RACING! On April 1-3, Classic Sports Racing Group (CSRG) hosted the David Love Vintage races at Sonoma Raceway. Z Car Garage had a blast racing and supporting several client’s Datsun 510 race cars running in B-Sedan Group 9 (John Morton Cup). It was a great weekend filled with competition, camaraderie and plenty of Alfas, BMWs and Datsuns sharing the track. Enjoy our report with in-car footage and photos.

Z Car Garage Supports Three Datsun 510s

It is our pleasure to bring more enthusiasts into the world of vintage racing. Our services do include full race support and car-preparation to help make client’s race days seamless and worry-free so they can focus on driving. One of our specialties is dyno tuning. Before a race weekend we confirm that your car is running well and make necessary adjustments while on the chassis dyno.

Video of two Datsun 510 B-Sedans (Rob and Tom), Enjoy the sweet L-series music!

ZCG clients running at the David Love Vintage races included:

#7 Kelvin

 

#71 Ed M

Ed is friends with Kelvin and started joining Z Car Garage last year. He also achieved a personal best lap time at Sonoma.

#7 Rob Fuller

Rob Fuller piloted the Bay Area Datsun Dealers tribute 510. Here is his report from the race weekend with in-car video:

“First CSRG race of the season and our favorite events to go to with a relaxed atmosphere and super cool people. This is one of the oldest vintage racing groups in the US and we love watching the B-sedan group grow. As we continue to report on these events it makes u happy to see more and folks racing and spectating. We want this sport to grow and be alive for the next generation of enthusiasts and drivers!”

 

“We headed to Sonoma Raceway, missing our buddy Tom Dockery in his Ex-Norm Balzer 510. It was involved in an incident on test day preparing for the event and will return soon. It was a superb race weekend for myself, Kelvin and Ed. We were cutting it up with Troy Ermish and Parker McKean (son of Bruce from PNW) in his fast Alfa.”

“Our buddy Josh Moriarty in his 510 had engine failure so Dave Rebello made a guest appearance visiting the track. We installed Rob’s back up engine into Josh’ 510 and he was able to finish the race weekend…that’s the spirit of vintage racing. We are all there to support each other and have a good time. Sure, it’s fun to be competitive but at the end of the day it’s more important to spend time with friends and family. It was a great weekend.”

Enjoy this in-car video from Rob’s 510 chasing Parker and Troy:

You can see more of Rob’s race videos from the CSRG event (and other race) on his YouTube Channel. Give the guy a thumbs up and subscribe while you are there!

A weekend of great racing and good times

 

It was so wonderful to share this experience with our friends and CSRG family. We look forward to another B-sedan event and special shoutout to ZCG crew including Nick F and Josh C. Running all of the cars above would not be possible without them.

  There were cool cars everywhere in the paddock:

  

Big thanks to Meghan for taking photos and video around the paddock. Here is a highlight reel of what it’s like at a vintage race…you should join us next time!

 

Always happy to see friends and newcomers at these events. New client Gabe and our buddy Geoff with his Dad:

We love to see owners installing our Z Car Garage CV Axles in their vintage Nissans and Datsuns. This 1971 Datsun 510 is owned by Jay W and he replaced his old CV Axle kit with our ZCG CV Axles.

Z Car Garage is proud to offer a CV axle conversion kit for your Datsun S30 and 510. We have sold over 200 sets of axles globally, with customers installing and enjoying them on everything from street cars to full-blown IMSA racers. These CV axles will help transmit power to the ground and ensure smoother operation compared to your standard half shafts.

  

For years we have used aftermarket CV axles that utilize an aluminum adapter prone to loosening up over time. Despite efforts to keep things tight (Loctite, hardware changes) we had to keep an eye on them. We developed a better solution that eliminates the need for aluminum adapters and remains 100% bolt-in like a factory half-shaft. These are the beefiest CV axles on the market. They have been tested on the track by our vintage racing customers and also in high hp* street cars. Each axle has a serial # for peace of mind and the kit comes with everything you need to install on your car.

Jay was looking for CV Axles to run on his 1971 Datsun 510 with Subaru R160 diff and stock 510 bolt-in stub axles:

“I’ve followed ZCG since you launched the Z Car blog years ago. When I first saw the axles on the blog I wanted to purchase them, but I already had the WCR CVs with adapters. I got tired of checking the adapters and safety wiring the bolts. The ZCG axles appealed to me due to their overall design and race proven duties. Talking to Rob about them earlier this year made the decision easy.”

Like many enthusiasts Jay wanted to install them himself as he enjoys working on his Datsun. He kindly sent us a few installation pictures of the ZCG CV Axles (set #0403) replacing the old CVs.

We were pleased to hear Jay’s installation went smoothly:

“I work in Mountain View, so I picked them up in person. Rob walked me through the process and pre-greased the CVs so installation was very simple. I had to adjust my exhaust a bit to clear the axles, but that was pretty easy. The build quality of these is top notch, I really like the details: The hole alignment marker and clearance for a box wrench. “

More install photos can be seen in the gallery below:

Datsun 510 Dreams

We actually know Jay from the days of the All-Datsun Meet at Mt. Shasta many years ago. Let’s hear how he got into his Dimes:

“I purchased my 510 wagon in Oakland in 2005. The seller had this green sedan in his garage he purchased new in 1971. He was performing an engine compartment refresh and swap. I offered to purchase the sedan too and a year later he called me back. The car was rolling, but all the parts were in various boxes or missing. Besides a clean body the car came with a DL Potter engine and Nissan competition transmission which had zero miles on them. I fell victim to project delays and scope creep due to work, family and moving.”

“I didn’t get the car on the road until May 2020. I also enjoy doing as much work as possible myself which definitely slows down progress. The goal with this car is to build a dependable well-handling driver which is period correct in appearance but can still be comfortable for my family. Much like the BTW 510 from Car and Driver. I plan to use the cars in some driving rally’s and the occasional autox- and track days.”

 

The car has changed a lot over the last two years and will continue to evolve as a driving project. As of today the car has this configuration:

Engine: L18, dual 40mm Mikuni carbs, custom roadster air filter, Fujitsubo exhaust

Drivetrain: Nissan comp transmission, Kameari flywheel, 4.11 R160 LSD

Suspension and brakes: 280ZX front struts and brakes, 240Z rear drums, Koni struts and shocks, 225 lb/in F and 900 lb/in R Swift springs, DPR bushings, 25mm F and 20mm R sway bars

Body: Resprayed body in early 80s, but close to factory color.

Interior

  

FloFit front seats, full carpet with extra sound deadening. Jay added some footwell lights which turn on with the dome light. Makes night access a lot nicer.

Enjoying the Ride

 

Jay has been driving his 510 everywhere, most recently on last weekend’s Breakfast Club Rally in Petaluma, CA:

 

Jay is stoked with the ZCG CV Axle performance and had a blast running the 510 through the Sierras on the DWA Rally in June:

“Rally was amazing, so much fun with a great group of people and cars. The 510 drove perfect and the prep paid off. Car is definitely underpowered at >8000ft above sea level. Still very fun.”

 

We love Jay’s attention to detail and it shows in his rally prep! Check out the skid plate his CAD designed:

 

Enjoy this video of Jay’s 510 in action:

 

 

Jay even made it out to Laguna Seca with his family in the 510 to watch the SVRA B-Sedan races (full report soon)! See more of Jay’s 510 on his Instagram.

 

Thank you Jay for your support and keep Enjoying the Ride! More photos in the gallery below:

“Just following up regarding the CV axle kit. I installed the kit right after picking it up from you in the beginning of March. Thank you for pre-greasing the CVs, and making the install pretty quick. Thanks again for making these parts, now I’m just waiting for the 510 brakes you’ll make. Also, congratulations on 18 years, that’s very impressive!”
