Vincent’s 1973 Datsun 240Z

Filed under: 240z,Featured Cars and Projects,Parts,Performance

Vincent S’ 1973 Datsun 240Z has a long history with Z Car Garage having received upgrades like our Z Car Garage Big-BrakesZ Car Garage CV Axles, full suspension refresh and dyno tuning.

 

The Z came back to us in March of 2022 for more power, drivetrain and interior improvements. Before we explore these upgrades, let’s take a look at how Vincent found the Z car of his dreams…

Z Destiny

 

Vincent: “I’m from Le Mans, France and attended the 24 hours race, or Le Mans Classic numerous times. In 2016, I was on the Le Mans racetrack with the car I had then (a Lotus Elise 220), and one of my very best friends, Fabrice. That day, we saw a gorgeous blue, track prepared 240Z that we loved. I took several pics and videos of it.”

 

A few months later, Vincent saw our friend Dave Scholz’ video on Petrolicious and found his Z highly inspirational. In Summer 2019, Vincent’s job offered him the opportunity to move to San Diego for a few years and he decided this is where he would search for his own Z car, and eventually send it back to France. It truly is a small world, and our client Brian P had listed his ’73 S30 on Bring a Trailer in September of 2000. Vincent saw the Z, bid and won the auction!

 

Vincent: “I bought my Z on BaT, from Brian P, who had Z Car Garage restore it. He loved his car and had to sell it, but the modifications he wanted to do included a Rebello stroker with Mikunis, etc…Living in the US for only 3 years, I decided to continue the story with Rob, and the Z is now what I wanted and what Brian wanted (I’m still in touch with him). Knowing that I was going to relocate to FR, I also became a member of the Datsun Club of France. ZCG was highly recommended by the group, and is a worldwide reference for Zs! The posts on zcarblog.com with all the pics, etc….are also great to see how the work is done.”

 

Back for the Z Car Garage Touch

While previous owner Brian P was a little bummed about selling the car, he was stoked that Vince shared his vision and dream to take it the rest of the way. We spoke with Vince and discussed all the upgrades he wanted to do, knowing it had to be completed before his expatriation June 30, 2022. The Z arrived at Z Car Garage from SoCal on March 1, and it was so good to see it again:

 

Drivetrain

 

When Brian was coming to ZCG it was during the “Butters” phenomenon: our clients wanted a similar setup for their own S30s. Our 1971 shop demo Z Mrs. Butters proudly features our Z Car Garage Big-BrakesZ Car Garage CV AxlesZCG Heat Shield, 6-speed transmission, full KW suspension (releasing soon) and 3.2L engine with triple-Mikuni induction. While Vince’s Z had the upgraded brakes, CV axles and suspension, the drivetrain was not touched.


We began drivetrain upgrades by replacing the stock L24 with twin-SUs/4-speed transmission with a Rebello 3L, triple-Mikuni induction and KA24 5-speed transmission. ZCG supplied the ph44 Mikuni carbs (jetted) with velocity stacks, ZCG mesh filters, Harada intake manifold, ZCG fuel rail and all of the things we do on the intake/exhaust side of the engine. Spark is provided by an MSD6AL ignition box. We also installed what every triple-carbed L-series needs: a ZCG Heat Shield!

 

A Moroso competition baffled oil pan prevents oil starvation with high cornering loads:

 

The Fujitsubo exhaust system from exhaust header to muffler was installed. These newer units have better fitment.

 

With the engine out we had our man William repaint the engine bay. ZCG engine bay services followed with freshly plated and plumbed hydraulic lines, hoses and general clean-up:

 

The engine bay turned out great and Vince wanted a red, powdercoated wrinkle valve cover. More photos of the engine bay details in the gallery below!

 

Driveline Upgrades

With the 3L engine in we focused on the transmission and rear axle. To handle the power from the 3L engine we replaced the stock 4-speed with a Nissan KA24 (FS5W71C) transmission. This was a common swap (before the CD009a came to market) performed by modifying a 280Z L-series bell housing. When we upgraded the transmission we also installed a JWT HD clutch with aluminum flywheel:

 

Helping put the power down efficiently is an OS Giken LSD. The R180 houses a 4.11 R&P and the assembly is setup in-house (by Joshua Corwin):

 

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 200 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 
 

Stock half shafts (L) and Vincent’s ZCG units, set #00295. Also visible are the T3 control arms:

  
 
 

Dyno Tuning

 

Rob dyno tuned the Rebello 3L engine making a stout 239hp/211tq to the wheels:

 

Enjoy the L-series music in this extended video of Vincent’s Z including dyno runs, test drive with Rob and drive-bys:

ZCG Big-Brakes

We are proud to have several of our ZCG products on Vincent’s 240z. We installed our Z Car Garage Big-Brakes (for small wheels) which have the been standard on numerous ZCG builds.

    
We removed the stock brakes and installed our ZCG Big-Brake kit.  We also installed a full coil-over (Koni) suspension from Techno Toy Tuning. T3 finishes the suspension in our signature color and we really appreciate Gabriel and his staff. They make some of the best suspension parts out there for Z cars.

 
 

ZCG Big-brakes and T3 coil-overs replacing stock setup:

 
   
 At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. New OEM Nissan master cylinder and Factory handbrake functionality IS retained!

 
 

Panasport Wheels

Complementing the new coilover suspension on Vincent’s Z are 16×7 Panasports and Hankook R-S3 tires in 225/50/16. We wanted the look and feel of Mrs. Butters Z so we obsessed over ride height until we got it exactly where he wanted it. The Z looks fabulous from any angle:

 
 

Recaro Seats

The stock seats were replaced with Euro-spec RECARO Pole Position in leather:

 

Driving is Believing

Vincent visited Z Car Garage for the first time when he picked up his Z on 6/22. Here is Rob showing Vincent the engine bay and going on a test drive:

 
 

Vincent:  “Rob and team ended up working 24/7 in the last few days so that this could happen. I picked it up on the 22 of June, early morning, when I believe I also met Alvin. It was amazing to meet you, Rob, and ZCG ! I then drove down the Pacific Coast Highway, to drop the auto in LA, where the logistics/freight company is. They finally put it on a boat 3 months later (and I now live in FR).”

 

Vincent was impressed with the upgrades from Z Car Garage:

Vincent:“What’s it like to drive??! Brian already had the brakes and axles done, so all good there. With the engine, gearbox, clutch, exhaust done + Recaros, it’s a complete different car to drive. Much more lively, direct, raw…the Recaros filter less than the original seats, but are now on par with the global performance and grip of the Z. I feel much more connected to the road.”

 

We are happy to report that the Z is now in France! Vincent picked it up in Le Havre (north of FR) and drove it all the way to Lyon (South east, where he resides). The engine started right away, and trip was a pleasure. He sent us some great photos (above):

Vincent:“Hey Alvin, I believe only 750 240Zs were ever sold in France back in the day…so you can imagine the looks I got! Some people thought it was a Ferrari 275 or a Type E…So grateful to Rob and the awesome job he’s done on the auto, and Brian, to whom I bought it, can be reassured…The Z’s being taken care of!”

 

Since owning the Z Vincent found out that the Blue Z he saw in Le Mans belongs to another member of the Datsun club of France, David Donne. Vincent also has been in touch with Dave Scholz, via Instagram who has been super friendly and helpful.


We enjoyed working with Vincent:

Rob: “All in all Brian would be super proud. Car was scheduled to be put on a container to go back to France and we made it with 1 day to spare. Huge thanks to Brian and Vincent. Super excited about this car and my only regret is that he doesn’t live local so we could enjoy it together.”

Thank you for entrusting us with your S30 Vincent and LONG LIVE THE Z!

Dyno tuning The 1971 Datsun BRE 510

Filed under: 510,Automotive History,Events,Racing
by Alvin G @ 5:10 pm on October 12, 2022

 

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:

 

Living Legends at the Velocity Invitational

 

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!

TUNING: Erik’s 1970 Datsun Roadster

Filed under: Featured Cars and Projects,g35,Performance
by Alvin G @ 3:11 pm on August 29, 2022

 

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

 

Erik heard about Z Car Garage through 311s.org, the definitive resource for all things Datsun Roadster. He purchased a G35 coupe and called Rob to talk about performance upgrades and the Infiniti was turned into a supercharged beast making 560whp.
JC1110213 043

“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!”

Enjoy this video of the roadster being dyno tuned and road tested, volume up!

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.

We have the pleasure of continually developing Dirk’s 1973 Datsun 240z to help achieve his vision of a Z car that is adept on the street and track. Improving the driving experience are our Z Car Garage Big-BrakesZ Car Garage CV Axles, Silvia 6-speed transmission and a host of chassis and driveline upgrades.

 

Dirk shares his experience working with us:

“Collaborating closely with Rob and ZCG has elevated the optimization process. Rob will frequently talk me out of a bad idea, or into a good one (like the OS Giken LSD). Sometimes I talk him into a bad idea and it turns out to work really well, like the S15 gearbox. The most fun is when we brainstorm stuff together like turning the catch can setup into an improvised simple PCV system, eliminating all hints of oil fumes from the car while running.”

Datsun 510, 620 and Z car love

Since our last iteration, Dirk as been back to Z Car Garage for a few major projects. Let’s take a look at his Datsun story first. Dirk bought his first Datsun in 2014, a 1970 510, to learn how to work on cars himself. After learning more about the history of Datsun, and the significance of both the 510 and the 240Z in establishing Japanese cars in the American market, he knew he had to own a Z as well.

 
 

A year later, the right Z showed up on eBay in Texas, a 1973 in silver gray. After pouring over the photos and talking to the seller, Dirk bought the car sight unseen. The idea was to have a nice Z to enjoy and drive, while continuing to work on the (sometimes not) rolling restoration of his 510. The car was lovingly restored by a dad and his children and in mostly stock condition. Dirk also has Datsun 620 work truck complete with dual-Mikuni’s:

  
After many more tweaks, different induction setups, spring rate changes, rebuilt stock brakes, and 24K miles of driving including a few track days, Dirk’s Z was inching closer and closer to his vision.

“After installing a Datsun Spirit STR-3 engine with a set of Nismo Mikuni PHH44 carburetors, the biggest weak spots left were the rest of the drivetrain (especially the stock 4-speed transmission, but the Subaru diff had also developed some bearing issues), the stock brakes, and of course the loose nut behind the wheel – but sadly that last component typically takes too much money and time to modify thoroughly.”

 
 

After comparing the Z to his Subaru BRZ on the track, it was clear the Z was better at everything except for shifting gears. Since his engine made a healthy amount of torque, but not enough to warrant a CD009 (350z) transmission, Dirk kept looking for alternatives. He also wanted something with slightly closer gear ratios to better suit the engine’s power band. An S15 Silvia 6-speed seemed like the perfect fit and we installed it back in 2019.

S15 6-speed transmission

 
 

The first S15 box had some weak synchros, so Dirk sourced another one that was installed with OE trans fluid, as well as a set of fresh OE motor and trans mounts to help with shifter feel and reduce vibrations in the car.

“The S15 transmission fit surprisingly well. ZCG built a custom crossmember to locate it, and the shifter lined up almost perfectly. No transmission tunnel mods were necessary. The modern shifter looked out of place, so ZCG built a custom unit that would look stock, and work with the Datsun competition shift knob. A small 6-speed shift pattern sticker modeled after the one used in the Silvia is the only clue there’s something different going on under this car. And of course the driving experience.”

Making the S15 shifter look factory, we are happy with the result and Dirk’s subtle shift pattern sticker:

 
 
 

The Datsun Comp shift knob complements the steering wheel:

 

Chassis and Driveline Upgrades

First, there was work to upgrade the steering geometry and suspension. With the car being lowered quite a bit, despite having 1″ RCAs installed, it had a ton of bump steer. Rob installed DP racing adjustable tie rods, removed the front springs, and completely eliminated the bump steer on the alignment rack while moving the suspension through its full range of motion.

New DP Racing tie-rods and in-house alignment:

 

We also refurbished Dirk’s steering rack with fresh parts from our stash:

 

With the Z back in the shop for bodywork we took the opportunity to make more suspension changes. New Koni Race shocks from T3 were installed, which were a much better match for the 300# and 350# spring rates than the Koni Sport shocks they replaced (as Dirk initially ordered the coil overs with lower spring rates, he never replaced the shocks after adjusting the spring rates, and the car always felt underdamped, particularly on the not-adjustable compression stroke):

 

ZCG Big-Brakes and CV Axles

    
Dirk visited ZCG and drove “Mrs. Butters”, our 1970 Series 1 240z shop demo car and he was sold on our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles! Butters has a way of doing this to our customers 🙂 As fellow S30 owner/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 M/C change or additional proportioning valve/adjustments. All fitting behind a 15″ Watanabe or Panasport wheel 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:

  
 

We removed Dirk’s stock brakes and installed our ZCG Big-Brake kit.

 
ZCG Big-brakes replacing stock setup up front:

 
 

At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality retained!

  
 
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 70 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 
 

Also visible on Dirk’s Z are the excellent adjustable lower control arms from Techno Toy Tuning.

 
 

3 Liter L-Series Power

Unfortunately, the Datsun Spirit engine developed rod knock which was the impetus for a big drivetrain upgrade. Several other parts of the car where refined as well.

 

The L28 engine was pulled, sent to Rebello, and built into a 3L powerhouse. Dave bored out the 44PHH venturis to a custom 38.5mm, to hit the perfect compromise between peak power and drivability. We also installed a fresh water pump, alternator, new fan blade, OEM fan clutch and fresh air filters. The beautiful DP Racing oil pan remained. More photos in the gallery below:

 
A custom stainless 2.5″ mandrel-bent exhaust mates with a new set of coated Pacesetter headers and Z Story Street muffler (in a search for a reduction in volume while keeping a nice note). Dirk discusses the clutch/flywheel combo below:

 

“The STR-3 already was able to slip the Exedy clutch and we were never fans of the Chromoly steel flywheel. A Jim Wolf Technologies clutch and flywheel combo was installed after first trying a newly developed Kameari single plate street clutch kit, which we both found too loud and racy for this street car. While the JWT pressure plate yielded a different pedal feel that took some getting used too, it was not too heavy and perfectly comfortable to drive in traffic. More importantly, it never slipped under any kind of abuse.”

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

 
 

We installed a ZCG-built 4.11 OS Giken limited-slip differential in the R180 along with a custom aluminum driveshaft:

 
 

Dyno Tuning

 

The previous L28 made 202hp/194tq at the wheels with Rob’s tuning. Now with the fresh 3L it baselined at 245hp/226tq with more area under the curve:

 

Rob tuned the car further on the chassis dyno, setting it up with a very lean idle at Dirk’s request (to minimize gasoline fumes at idle). With A/F optimized and Nismo Mikuni carbs massaged, Rob unlocked another 20hp yielding a stout 265hp/232tq to the wheels:

 
 

With gains of 62hp/37tq at the wheels over the L28, Dirk is very happy with the new 3L:

“While the Datsun Spirit engine had a very peppy mid-range and made more delicious induction noises, there’s no argument that the more powerful Rebello engine elevated the car to the next level of performance and fun. The entire setup worked incredibly well together, and we hit an impressive 265hp at the rear wheels, or 60hp more than the engine made in its previous iteration, putting it in the 100hp/liter ballpark at the crank. Not bad for a dinosaur engine on California pump gas!”

Enjoy the dyno video and L-series music!

 

Sorting

The little things are what we excel at and Dirk had a list for us to knock out. While at ZCG, we replaced the heavily sandblasted OE windshield, and did some rust remediation in the cowl area, as Dirk had started noticing water making it into the interior fan assembly after washing the car. More photos in the gallery below:

 
 

The heater and blower motor assembly was refurbished with new ducting seals and lubed linkage:

 

The headlight switch had also developed some issues where sometimes the lights would turn off completely when switching between low and high beam, and was replaced with a good used example from the ZCG parts stash.

“The headlights now worked reliably, the new engine didn’t consume any significant amount of oil, and the whole drivetrain worked together even better than before with the new clutch and flywheel combo.”

 

Unfortunately, 7 months and many miles later, Dirk was back after a minor nighttime crash that took out the left fender, front bumper and valance, and dented the hood. After bodywork and paint from our man William from William’s Auto Body, we installed a euro front bumper, used turn signal assembly, cleaned up electrical wiring from alternator through firewall and sorted his Speedhut GPS speedo box.

 
 

To improve safety, comfort, and avoid future crashes, Dirk upgraded his headlights to a new set of Holley Retrobrights, and GTR Carbide 2.0 turn signal bulbs front and rear from Headlight Revolution.

“The headlights are a world ahead of the old Maxxima LED units, which themselves outperformed the Sylvania Halogen sealed beams, while staying very under the radar, with their sealed beam-inspired looks. And the turn signals are now highly noticeable, even in the brightest daylight.”

 

Enjoying the Ride

Dirk’s been driving his Z-car pretty much every day since the latest upgrades, and it’s been working phenomenally well:

“The drivetrain + brakes make it as happy to accelerate as it is to stop, and with the quick, closely spaced shifts and eager engine, it’s fun to do a casual grocery run, and to drive quickly. With the electrical systems and all fumes well under control, it’s truly a car you can do anything with, and probably more reliable than my BMW.”

 

We loved to see Dirk driving his Z on rallies and fun runs this year. Most recently we joined fellow Japanese vintage car owners on the Tokyo Calling event hosted by Breakfast Club Rally:

 

Dirk also joined us for a New Year’s Day drive through our favorite Bay Area Backroads:

 

We enjoyed working with you Dirk and it was rewarding to help improve your Z.

“Some say good is the enemy of great, but that’s true if you think you’re done. I don’t see my Z car less as a “build” that’s done. I’m always developing it, just like continually developing a race car (e.g. my Lemons car, http://instagram.com/bittersc243) to stay competitive. In this case the competition is merely for making the Z into the most fun driving experience I can imagine, and the journey of continuous refinement and improvement is a big part of the fun for me.”

 

While Dirk works through a few interior projects (new carpets, stereo upgrade) on his own, we’re getting ready to further revise the front suspension/steering, and wider wheel + tire options. Enjoy more photo documentation of our work in the gallery below. Thanks for your support Dirk and LONG LIVE THE Z!

 




ZCG PARTS: Z Car Garage CV Axles for Jay’s Datsun 510

Filed under: 510,Parts
by Alvin G @ 5:10 pm on July 18, 2022

 

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:

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:

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!”
