Gary’s 1971 Datsun 240Z featuring the Datsunworks KN20 twin cam (DOHC) cylinder head is for sale. This S30 has been with Z Car Garage since 2008 where it received a full bare metal restoration with continuous performance development to its current form. Featured in numerous magazines, SEMA, and Japanese Classic Car Show. Fantastic fit/finish with chassis and running gear to keep up with its exotic engine. It is a magical experience to see, drive and hear the “Behemoth” in action. See more details below and serious inquiries only please contact rob@zcargarage.com

 

Drivetrain

 

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 and Z Car Garage CV Axles

-Rear Diff: R180 4.11 OS Giken LSD

 

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!

 

Body/Interior/Chassis

 

The “Behemoth” wears one of the best paint finishes we’ve done with fit/finish we feel would be hard to replicate. We collected parts for years to build. Glass was polished, unobtanium parts sourced. The interior features a fully restored dashboard with Recaro Specialist seats, power windows and a fully integrated roll cage. You can see the body restoration and chassis development here  HERE.

 

The Z has early versions of our Z Car Garage offerings like 17″ Panasport C8 wheels (NLA), full coil-overs/adjustable suspension throughout and ZCG Stoptech ST42 (328mm) Big-Brakes:

 

Enjoy The Ride

 

Beyond the show-quality features and impressive drivetrain, this Z car loves to be driven and has attended many car shows, gatherings and road rallies like the 300-mile Tokyo Calling event hosted by Breakfast Club Rally

You can see it in action on the rally in the video below:

 

Gary’s Datsun 240Z will always be the pinnacle of Z car builds for us. It is ready to be enjoyed by the next owner and all we ask is that you give it the same love and respect we have given over the last 15 years. All sale inquiries can be made through Rob: rob@zcargarage.com. See below for all of our documentation of the this Z including every video, magazine feature and blog post:

L-Series Music

Rob took me for a spin in both cars. It was exhilarating. Volume UP and Enjoy!

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!
