Z Car Garage is excited to collaborate with Datsunworks and develop their brilliant KN20 dual-overhead cam (DOHC) cylinder head designed for the Nissan inline-6 L-Series engine. This is a Honda K-series derived cylinder head with superior flow rates and modern valvetrain components effectively transforming your SOHC L-series into a high-revving DOHC engine.

 

We have installed the Datsunworks head into our client Gary’s Datsun 240Z (affectionately called the “Behemoth”) and it is currently in the tuning/testing stage. In conservative tune it made 350hp/248tq at the wheels. Recently we joined photographer Naveed Yousufzai at a photoshoot for full feature on Marqued.com. Check out the story and amazing photos by Naveed with amazing shots at Marqued HERE.

 

The photo shoot left us breathless and we really appreciate how the small details are captured like the Behmoth’s integrated roll cage, Recaro seats, 6-speed shift knob and 10krpm tach…check out the feature!

 

This video shows behind the scenes action of the photoshoot for Marqued.com. I tried to capture the incredible induction sound the KN20 creates. For the first time we cruised on the freeway together with the Behemoth…it was the “trifecta” with 240Z, 510 and Datsun Roadster. Turn up those speakers and enjoy!

David O. has been a Z Car Garage client since 2005. Together, we helped achieve his vision of a fully restored S30 with multi-dimensional performance: a daily driver that is equally adept at canyon runs and open track events. 17 years later David is still Enjoying the Ride and recently visited us for track day preparation.

 

Before we get into the build details dating back to 2005, let’s hear from David on his recent track day experience.

Take it to the Track!

 

David is an avid motorsports fan and driver. The Z has seen many track days since the restoration and came out of storage so he visited Z Car Garage for a pre-inspection.

 

We bled the brakes and made sure everything was ready for the event. He had a great time:

“It was my first time back on the track with the 240z in several years. I went out for half a day with Hagerty Insurance and their affiliation with SCCA’s Track Night in America. The people were great and it was a very “docile” track day with mandatory point-by’s even in the advanced group. It was a great way to knock the rust off after a few years off the track.”

“Rob Fuller prepped the car a few days before and she behaved beautifully. I managed a 1:59 lap but I was lifting a bit going up to turn six because I was afraid of breaking the 90dB sound limit. Of course, Z-Car got a lot of love from the other attendees. :-)”

Enjoy this video of David’s Z in action with in-car and chase footage from Laguna Seca and more:

 

History

 

We met David and his newly acquired Z in 2005. Long before the days of Facebook and Instagram, our mutual friend and Datsun fanatic Tom Dockery referred David to ZCG:

“I’ve been working with Rob since February of 2005 when I purchased my 240z from a guy in Redding. It was a true barn car. He drove it down and Rob inspected it before I bought it. I didn’t know anything about the car except that I wanted something fun to drive with a manual transmission. I’d always thought the 240z was cool because my 5th and 6th grade teacher had one – and she was very cool.”

“The first weekend I had the car it rained really hard and I found out all the seals were useless. There was about a quarter inch of water in the car and mold had already started growing. I took it to Rob, and once the seats were out, and the carpet was out, and the seals were in, Rob suggested the Recaro seats, the roll bar, and harness. It was just about that time I did my first track day in someone else’s car, and I decided I wanted to track the 240z. And that’s when I started what I call the “accidental restoration.”

Paint/Body

 

While we do not have in-progress photos of the restoration, there are many shots of David enjoying the finished restoration. Our man William worked his magic to apply the Nissan 112 Paint (Tennis Ball Green). David recalls his vision for the Z:

“My goal when restoring was to have a track-ready, fun to drive machine that did justice to the original car. My car was originally orange, was red when I purchased it, but I wanted something different. That’s when I went with the tennis ball green color, which was one of the original colors. It was manufactured in October of 1971, so she turned 50 just last fall.”

 

Engine

 

Full engine bay services included re-plating and powdercoating parts. The L24 was replaced with factory-spec L28 with triple-Mikuni induction. A custom cam was designed by Rob for better top-end performance. The Z put down 167hp/174tq at the wheels on the ZCG dyno:

 

Interior

 

There’s very little on the car that was left untouched – David took pride in the interior:

“I pretty much went with Rob’s suggestions (pros and cons) and learned while I went along. The gauges were all me. As much as I liked the originals, the were just too dim and difficult to read at night. I replaced them with white-backed Autometer gauges but kept the green backlighting. I also kept the original turn signals and embedded them in the new gauges. I didn’t keep the clock, and the fuel gauge is the carbon fiber reinforced glove box.”

 

More details like Recaro seats, Roll bar with 5-point harnesses, updated fuse box and high voltage bypass for the steering column, 260z lighted console panel and Sony bluetooth radio. Outside, Euro tail lights with LEDs:

 

Z Car Garage Big-Brakes

 

David’s Z was the first one to receive our Z Car Garage Big-Brakes. This was our initial (2008) setup utilizing Stoptech ST-40 calipers and our own brackets. We had extensive track testing with pro-driver David Ray:

 

James’s also runs this 328mm kit on his turbocharged L-Series beast, Medusa. Not to be confused with our current Z Car Garage Big-Brakes!

  

Enjoying the Ride

 

We have Enjoyed the Ride with David at many events over the last 17 years. Most recently I got to catch up with him at our New Nissan Z event. His Z still looks amaZing!

 

Here are few events from years ago with David…some of you might remember attending these too!

2008 ZONC Blackhawk Museum Car Show

 

2010 and 2011 Palo Alto Concours d’ Elegance – the crowd loved his Z car!

 

2008 Motoring J Style…remember we had a superb turnout for the caravan starting at Z Car Garage!

 

2008 and 2011 Silicon Valley Auto Show at the San Jose Convention Center

 

Long Live The Z!

Thank you David for your support and friendship all these years. We love that you keep your Z on the road and it makes you smile behind the wheel whether its on the track or or street. Stay tuned as David will be returning to ZCG later this year for 3.1L engine upgrade! More pictures in the gallery below…

We love to see our parts installed and used on client’s cars. Race car driver and restoration specialist Jim Froula of Racecraft is running our ZCG CV Axles in this Nissan IMSA GTU 300ZX race car!

 

Jim installed CV Axle set #269:

The George Alderman Z31

 

Over a 49-year competitive career, George Alderman was one of America’s most successful sports car drivers, racing in Sports Car Club of America (SCCA) and International Motor Sports Association (IMSA) events.

 

In the 60’s and 70’s George would race a variety of cars. He won the IMSA Baby Grand championship in 1971 in a Datsun 510 and in the 80’s he drove Z cars in the Camel GT series. His Z31 would run both turbo and NA classes for IMSA.

 

Out of 70 starts he had 50 top-tens, 27 top-fives, and 5 wins, all while successfully running his Datsun/Nissan franchise. (Below) a 1988 promotional photo of the  Z31 in front of Alderman Nissan, in V6 IMSA GTU class trim. Find more history on this Z as documented on Alderman Machine.

 

Restoration at Racecraft

 

Jim and the RacecraftNW crew restored the George Alderman 300ZX. As usual, Froula’s painstaking efforts and diligence result in a faithful restoration. Original frame (left) and restored with chassis parts:

Set #248 – installed on Adam Carolla’s “Greg Sorrentino #90” Datsun 510.

 

 

 

 

 

Last Friday we made some glorious L-Series music with two of our client’s Datsun 240Z cars. Gary’s Datsun 240Z, affectionately named the “Behemoth” has accumulated some mileage on the Datsunworks KN20 cylinder head and the dyno confirmed the same power level.

 

Khang’s 1973 Datsun 240Z was completed in October and he returned with 1,000 miles on the 3.2L L-Series. We adjusted the valves and double-checked power levels.

 

Happy to see both builds healthy and confirm power output. Enjoy the music from the both L-Series engines, sporting Jenvey ITB EFI managed by Haltech 750 Elite ECUs backed by the CD009a Six-Speed transmission. LONG LIVE THE Z!

 

 

 

 

 

Our client Jas D listed his 1991 Aztec Red 300ZX Twin Turbo for auction on Bring a Trailer. You can view the auction HERE. Below is our blog feature of the Z, enjoy and happy bidding on this stunning Z32.

 

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:

 

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!”

  

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.

 

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:

 

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

 

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:

   

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

 

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

 

OEM vs SPZ:

 

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:

   

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:

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:

 

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 will be 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!
