We have several exciting projects at the shop that will get full reports on zcarblog.com but today we want to highlight a few cars that we prepared for next week’s ZCON event. Please tune into our Instagram story for more sights and sounds as we have Z32, R35, S30, 370z, 350z, S130 and yes, even some Z31 updates heading your way!

 

ZCON Here We Come!

 

Z Car Garage is proud to be a sponsor for the 34th Annual Z Car Convention (ZCON) hosted by ZCCA in Colorado Springs 8/16-20. This is the largest Z-car event in the US and we are stoked to participate. Here are three client cars destined for ZCON, enjoy!

The OMS Pace Car

 

This is a 1972 Official OMS Pace Car Duplicate. It is at present one of only two known survivors . Fifty were originally produced by Nissan Motors to commemorate the DATSUN 240Z being selected by the Ontario Motor Speedway to Pace the 1972 “U.S.A.C. California 500 Championship”.  It really is a small Datsun world, as the official OMS pace car is none other than our very own Joel Anderson #49 IMSA GTU 240Z .

 

This OMS duplicate belongs to our long time customer and friend Linda. She acquired it from a family in SoCal and tasked ZCG with making it a nice driver. Full report soon but it got loaded up today for its journey to Colorado!

 

Jack’s LS3-Powered Z32

 

Jack and Yolanda have been a part of our lives since the beginning of ZCG. Being long time members of The Z Owners of Northern California (ZONC) and supporting our shop along the way, we are grateful to them. ZCG will be restoring the Primadonna Z back to its former glory this year! We are also helping the couple finish their LS3 V8 engine swap into their “Primadonna” Z32 Convertible. Yes, Jack had to get back in the game after building those 240z cars so he built a Z32 body kit from scratch. Like the S30’s he built, this widebody Z32 has evolved over time:

   

ZCG finished the LS3 swap and dialed it in with road-testing and dyno tuning.

 

It even sports full A/C and OEM shifter for the automatic transmission. The Z was loaded up with the OMS pace car today and heading to ZCON, full report soon!

 

 

Mike’s Datsun 240Z #193

 

Mike’s vin # 193 Series-1 S30 was ZCON bound but needed further work to be truly show-worthy. We love that he’s on board with us to finish the car correctly. It’s a beauty and it will be sensational.

 

Z You There!

This will be an eventful week for us. ZCG will be attending the Rolex Monterey Motorsports Reunion this weekend, then it’s on to New York for the Global Reveal of the New Z and finally we will be in Colorado on Friday for ZCON! We are stoked to see the cars, faces and meet new people. Watch our IG/FB and twitter for updates!

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.

 

Datsunworks founder Derek Minetti is the pioneer behind the KN20 DOHC cylinder head. This is a custom (very limited production), 6-cylinder head derived from Honda’s venerable K-series 4-cylinder engine. The KN20 offers superior head flow rates combined with modern valvetrain components to effectively transform your L-series single-overhead cam into a high-revving, dual-overhead cam engine. The power potential is impressive.

Gary’s Datsun 240Z

 

There are ten KN20 heads in the wild with only three installed and currently running in cars. Z Car Garage has two KN20 cylinder heads. This KN20 is serial #SN10 and it has been installed into our long-time client Gary’s Datsun 240Z, affectionately named the “Behemoth”. ZCG is always exploring the boundaries of powertrains and Gary’s Z has seen a few engines including an RB30DET, OS Giken TC24 and now the Datsunworks.

 

Here are few details on the powertrain setup for this Z:

-Rebello 3.1L Engine

-KN20 Cylinder head SN10 (but the performance level goes to 11)

-Induction type: Jenvey ITB EFI with Injector Dynamics injectors

-Engine management: Haltech Elite 750

-Header: Equal-length, custom fabricated by RacecraftNW

-Transmission: Nissan CD009a

-Rear Diff: R180 4.11 OS Giken LSD

 

Pictures of the initial engine installation, with more in the gallery:

 

For further information on the KN20 cylinder head we urge you to visit the Datsunworks blog:

Performance

 

We are still in the tuning phase so Gary’s car is on a comfortable (conservative) setting. With the Datsunworks head it made 350hp/248tq at the wheels on 91 octane:

 

Even in a testing stage it is absolutely thrilling to drive. Gary’s car is a full ZCG-style restoration so it has the chassis to harness the power. The sound it makes is a sonorous tone only the K-series derived KN20 head creates…with a gnarly exhaust note to match. The ITB induction also provides a healthy wail…it’s a sensory overload and revs seem to climb endlessly.

 

To illustrate the Datsunworks experience we captured some video of what it is like to drive around town…the 6-speed and EFI really allow this car to be docile, especially when cruising on the freeway and at part throttle. Drop a gear and its becomes a wild animal. Not going to lie…it gave me goosebumps both as a passenger and spectator.

Watch the video complete with multiple dyno passes, street acceleration and fly-bys. VOLUME UP!

 

 

Potential

 

Z Car Garage is stoked to be a part of the Datsunworks KN20 development. It is a clever design that pushes the envelope for L-Series engines. Sharing this experience is also part of the fun so we anticipate having a KN20 setup in a dedicated shop 240Z for clients to test drive and further evaluate. Although each application is different, we envision offering a bolt-in setup for your six-cylinder L-Series engine. The power potential is tremendous with the KN20…both NA and forced induction. We thank Derek at Datsunworks for giving us the opportunity to work with this innovative product.

 

Stay tune for more updates and LONG LIVE THE (TWIN CAM) Z!

The iconic, 1976 IMSA GTU Championship-winning Transcendental Racing Z is at Z Car Garage! This early 1970 production 240Z has an exciting history battling against factory-backed teams with names like Jack Scoville, Brad Frisselle and John Morton behind the wheel.

 

The chassis was also highly-developed by a team of All-Stars including Joe Cavaglieri (Crew Chief), John Knepp (engine), Trevor Harris, Mac Tilton (suspension) and Yoshi Suzuka (chassis, roll cage and body). Current owner Randy Jaffe has commissioned Z Car Garage to bring this Z back to period livery, refresh the chassis and drivetrain components, and re-assemble the interior before traveling to its new home in Atlanta.

 

The Z came with many spares, period photos and even original molds for the bodywork!

 

Getting the livery sorted has begun, with a proper “Frisselle” windshield banner (left) based on period photographs (right)

 

Here is a short video of the Z as it arrived to the shop early this week. Dyno testing with video coming soon!

 

Always Meet Your Heroes

 

The “Frisselle” car captivated us for many years. We watched it race locally and and eventually shared track time with previous owner David Martin (RIP) at major historic events. (Below, Left) David Martin and Rob Fuller (#49 Joel Anderson car) in the Corkscrew and (Right) Rob with David and Brad Frisselle at the RMMR 2018.

 

You can imagine how excited we are to have this iconic race car at Z Car Garage. Big thanks to Randy for always believing in us. More photos from my brief visit:

 

 

Enjoy these videos we’ve captured over the years racing with David Martin piloting the Transcendental Racing 240z:

 

In a moment of sheer happiness, Rob Fuller can be seen driving the #47 Brad Frisselle Z through the paddock back in 2015!

 

A David Vs. Goliath History

Ever wonder about the history behind this famous 1976 IMSA-GTU Championship-winning 240z? Check out www.my240z.com. Our friend Glenn Chiou created this website to document the racing provenance for previous owner David Martin (RIP):

 

Glenn’s impressive knowledge of historic Nissan/Datsun racing is bolstered by hundreds of scanned photos, some never seen before along with stories from ex-drivers Brad Frisselle, Jack Scoville and John Morton. We are even given new insight on the R&D effort that went into the Frisselle car making it by far, “the best race engineered 240z in its period”.

LONG LIVE THE Z!

 

Race car driver, restorer and Datsun Historian Glenn Chiou visited Z Car Garage today for dyno tuning on his IMSA GTU 260z race car! You might remember our previous blog post highlighting the ZCG CV Axles Glenn installed himself:

    

Glenn is preparing for the upcoming Rolex Monterey Motorsports Reunion at Laguna Seca and we specialize in dyno tuning vintage race cars for the event. Listen to that triple-Mikuni fed L-Series roar on the dyno…Glenn is dialed-in and ready to race!

 

 

The Different Drummer Z

 

Glenn Chiou is our client, fellow racer and friend. He was one of the first to run our Z Car Garage Big-Brakes on his RHD 240Z and actively vintage races both 510 and Z cars. You may have seen Glenn’s FAR Performance 240Z in VIPS Restaurant livery as raced in the 70’s by Loren St. Lawrence. Glenn restored this race car himself and it is now going back to Bay Area Datsun Dealers livery as raced by FAR Performance privateer Walt Maas. Glenn’s got a passion for re-telling the stories of legendary privateer Z car racers and his current restoration project is the Different Drummer Racing Z raced by Greg Sorrentino. This is a really cool race car with great history and build details behind it.

 

Chassis # RLS30-000024 is a July 1973 pre-production Datsun 260Z chassis that was sold by the factory for one dollar in 1975 to Different Drummer Racing, owned by Greg Sorrentino of Troy, Michigan. It was one of the very first Datsun 260Z chassis and was built by the legendary American fabricator, Ron Fournier. This Z car has been consistently raced for the last 40+ years in IMSA GTU, SCCA Trans-Am, and C-Production/GT-2 classes. You can see more history and details of the build HERE.

 

Thanks for your support Glenn! We we will be rooting for you at the Monterey event!
