It’s 90’s Monday at Z Car Garage! We had two R32 Skylines in from our friend Sean at IVI. The (AH3) Pearl Red Metallic GTR came in for stainless brake lines, timing adjustment and alignment. Kurt’s (KH2) Grey GTR will be getting wheels(though we dig the R33 setup!), Stoptech BBK, Haltech and more ZCG R32-specific upgrades.

 

The shop 300zx, representing our favorite 90’s-era Japanese sports car also got a set of Volk GT-C wheels:

 

 

 

 

 

 

 

Matt O is the lucky owner of this 1991 Skyline GTR finished in (TH1) Midnight Blue Pearl.  When we first met he wanted to bring the car in to ZCG for a quick checkup. We looked over it, ran a compression check and also made a plan for his next visit.

 

Matt acquired this California-legal R32 from our friend Sean and his team at Toprank International Vehicle Importers. It goes without saying, if you are in the market for a vintage Skyline (or any JDM car) IVI is the place to go.

   

In March of last year Matt came in for a Haltech Platinum Pro. We have installed many of these and it’s a great foundation for adding power to the R32.

 

We performed all the prep work and ran a the boost sensor to install the Haltech.  Whenever we take on these cars we always run a smoke test to ensure there are no intake leaks present.

  

On the dyno, results for the baseline run (left) followed by Haltech on 91 octane. Despite having a healthy engine/turbos the power levels were fairly low on this car. The culprit: weak actuators not allowing the car to hold boost. Matt will visit us again for new turbos and acuators so it will get a big jump in power. We are big fans of Haltech and now he’s prepared with the right engine management system.

  

Next, we installed a few suspension upgrades supplied by Matt followed by a full alignment:

 

Cusco T/C rods, rack bushings and toe-link/rear control arm setup:

    

T/C rods

   

The R32 had a set of SSR SP1 wheels and Matt wanted to change the look with a fresh set of new wheels: 18″ Volk TE37 finished in bronze.

  

We mounted/balanced his RE071R tires and the Skyline looks sweet:

Matt has been Enjoying The Ride in the R32. Here he is at Laguna Seca:

  

We even caught Matt out on a local drive! Here he is parked next to Naveed’s R32 (story coming soon):

 

Thanks for bringing your Skyline to us Matt. We look forward to more boost! Catch more of Matt’s Th1 R32 on his Instagram

 

Neal D brought his 1972 Datsun 240z to Z Car Garage after being restored by a shop in SoCal last summer.   He wanted us to get this 918 Orange beauty running correctly and double-check the workmanship performed so we happily obliged.

 

The Z had several issues that we resolved after a thorough inspection. Starting with the braking system, we corrected and re-routed all hydraulic lines. The front and rear circuits were swapped on the brake master cylinder, we corrected this as well. The pin from the brake booster to the M/C was adjusted to enable a good initial “bite” from the pedal. Our usual ZCG brake services included Stoptech 309 pads. Finally, we bled the system and adjusted the rear brakes correctly.

   

The transmission had to be removed to correct issues in the clutch area. We found stripped bolts, a mis-adjusted clutch pedal, and incorrect T/O bearing collar hardware:

   

Moving down the drivetrain, we found and corrected improper hardware on the half shafts:

  

We nut/bolted the entire car, correcting all suspension issues like improperly lubed bushings. More detail work: the wiper system beneath the cowl was setup incorrectly being 180 degrees out.

  

A critical part was missing from the fuel system: the vapor tank. We removed the fuel tank and replaced all vapor lines with our ZCG aftermarket hose kit:

  

The missing vapor tank was re-installed and the entire system was smoke tested to confirm proper sealing. A full fuel tank was also included in our testing:

  

Neal wanted the car back on the road in top driving condition. We installed an O2 bung into the exhaust and street tuned the Z after adding a Pertronix ignition. The Z was dialed-in and ready to rock:

 

Neal has owned this Z for many years but also loves his Porsche 911. When we met at Rennsport we gave each other that look: P-car or Z-car we both Enjoy The Ride! Thanks for bringing your Z to us!

 

 

 

 

 

 

Z Car Garage is proud to offer a CV axle conversion kit for your Datsun S30 and 510. We have sold over 100 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. Full details below:

 

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.

  

Designed and manufactured locally with KAD Models, the ZCG CV axle kit works in both R180 and R200 configurations.

 

  

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 (powershifting, clutch dumps, etc.). Each axle has a serial # for peace of mind:

 

The CV axle kit is available now from ZCG for 1595.00 + freight and they come with everything you need to install on your car. Contact us at 408-452-0350 or send Rob an e-mail rob@zcargarage.com to purchase. Installation is just like doing a half-shaft: there is even a marking that shows you where to line up bolts and special hardware:

 

The ZCG CV Axles in action

The video below demonstrates the “looseness” associated with aftermarket CV axles that use adapters compared to the ZCG axles without adapters. Several customer race/street cars running our CV axles are also shown. Enjoy!

 

S30 and 510s running the ZCG CV axles

 

Randy Jaffe’s #46 BRE Datsun 240z received the very first set of ZCG CV axles: Serial # S30-000240!

 

The Bluebird SSS Coupe and Hakosuka Skyline are both running ZCG CV axles on the race track:

   

Race car driver and restoration specialist Jim Froula of Racecraft is running ZCG axles in several of his cars:

Set #246 – installed May 2018 on the “Harry Stewart #52” Datsun 510:

  

Set #247 – installed April 2018 on the 260z

  

Set #248 – will be installed on Adam Carolla’s “Greg Sorrentino #90” Datsun 510. We are pleased to report that Jim will also be installing a set on his “George Alderman #32” 300ZX! The ZCG CV axles are also perfect for high hp street cars. The following customer cars are all running our CV axles now:

Frank B’s fuel-injected, 6-speed stroker L-series:

  

Gary’s 430whp LS3-powered 280z:

  

Scott W’s EFI stroker L-series:

Finally, Gary’s “Behemoth”  OS Giken TC24B1Z powered S30:

Technical Information:

The Z Car Garage axles were designed to help remove much of the backlash aka clunk seen in many older vehicles. Modern technology has given us the ability to create a set of axles to exacting standards. We started with a high quality set of CV joints that were found to be the most consistent in both major and minor spline diameters. We then began to design the axle itself to share the same tight tolerances. We are holding a +/- .01mm diametric tolerance on both the inner and outer spline diameters. This gives us the feeling of direct connection between differential and wheel. The axle shaft major diameter was increased to 30MM to give owners a bit of added comfort in knowing the main shafts are stout. Once the axles are splined they are then heat treated to obtain the desired harness. After heat treat the axles are then nickel plated to add corrosion resistance. The inner and outer flanges are made from 316 stainless steel and mate to the CV joints with tapered alignment surfaces to ensure concentricity is maintained throughout the axle thus reducing vibration. The inner flange attaches to the stock R series differential utilizing the Nissan factory hardware. The outer flange attaches to the driven stub with bolts specifically designed and manufactured for the Z Car Garage axle installation kit. These bolts are manufactured to grade 12.9. All ZCG axles are manufactured locally which helps us maintain the fitment and quality we require.
