Speedhunters, the popular car culture website, appears to be inactive. While there’s no official announcement of the site’s demise, like many fans and followers of the site we are disappointed. Speedhunters was known for its high-quality photography and in-depth stories about car culture.
We’ve gathered all 14(!) Speedhunters articles featuring Z Car Garage clients and friends here for you all to enjoy. Who knows how long the site will remain on the web, so click on the photos or links below to read the full features by authors/photographers Trevor Ryan, Naveed Yousufzai, Larry Chen and Mike Garrett.
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
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:
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.

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.

Our ZCG Big Brakes have been winning over Z-car enthusiasts locally and globally. Jeremy G recently purchased a set for his 1973 Datsun 240Z and performed the installation himself at his shop in San Jose, CA.
Big-Brake Kits Available For DIY Install!
Z Car Garage is proud to offer our Big-Brake Kit to Z-Car owners that want to perform the installation themselves. We can ship worldwide and each kit contains everything needed with a comprehensive (40-page) installation guide. Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE. Enjoy these pictures of Jeremy’s beautiful S30 and his ZCG Big-Brake installation:
As mentioned, our ZCG Big-Brake kit ships with everything needed to install and retains the factory parking brake:
Jeremy successfully installed the BBK on his Z, complete with functioning parking brake:
The brakes fit behind his 15×9(F) and 15×10 (R) Longchamp XR-4 wheels:
Beyond ease of installation and quality components, our Big-Brakes perform by offering superb pedal feel…everyone that drives our demo Z confirms! 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. Jeremy was very happy as well with great feedback:
“Big thanks to Rob Fuller and the guys at Z Car Garage for working with Stoptech to make this awesome big brake kit for S30s. Installed yesterday and spent most of today running around and they feel great. Best feeling and balanced brakes I’ve ever had on any Z.”
Jeremy removed and sold his existing Wilwood setup, not uncommon once you experience just how good our Big-Brakes are!
A 3.5L Driver
The best part is that you can see Jeremy frequently Enjoying The Ride all over the Bay Area. This Z gets driven! Under the hood is a Rebello 3.5L soon to be fed by 50mm Mikuni carbs tuned by Kyushahousetaka. We dyno tuned the Z last year with 44s and this G-nosed beauty baselined at 238hp/229tq. With Rob’s tuning the Z produced 288hp/257tq to the wheels! We are really excited to unlock more power with a few upgrades, now that Jeremy has brakes up to the task!

You can see even more pictures of the Z on Speedhunters HERE. Looking forward to more tuning sessions and thanks for your support Jeremy!

Long Live The Z!
It takes teamwork to make the Dream work. We want to thank Love20bee for sourcing and re-finishing these SSR Watanabe RS8 wheels for James’ 1972 Datsun 240z.
It has been said that “wheels make the car”. Matt and his team nailed it with these RS8s sized 10.5 (F) and 12.5 (R) on massive 275/315 width Nitto NT-01 tires.
While they look killer standing still, they are even sweeter in motion as seen in the video below:
Rob and owner James are proudly wearing Love20bee hoodies. We highly recommend Love20bee for your wheel needs. Check them out on Instagram and Hoonigan Autofocus.
