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:
Our client Gary’s S30 with the Datsunworks KN20 twin-cam cylinder head is featured in the popular Japanese magazine, “Option”.
Supporting the 3.1L engine are our Z Car Garage Big-Brakes, Z Car Garage CV Axles, Jenvey ITB EFI with Haltech Elite management, Nissan 6-speed CD009a transmission and OS Giken 4.11 LSD. You can view the article HERE.

Client Updates for 2023
We had a busy year and though the shop will be closed, we won’t leave you hanging for the holidays. Many zcarblog features have yet to be published like our belated race report from the CSRG Charity Challenge and Finale in addition to client stories. Before we take a look back at highlights from 2022, here are several exciting projects coming along at the shop:
Jeff and Ryan B’s LS3-powered Z came to us for mechanical sorting. It’s now sporting our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles. Ryan successfully ran the Targa California Rallye in blistering summer heat. He recently got a new set of VOLK TE37V wheels full report soon!
At Z Car Garage we enjoy both modifying Z cars and restoring them back to factory spec. Mike’s 1970 Datsun 240Z came to us from North Carolina and we delivered it in July. This ’69 production VIN#193 is a beautiful driving example of how wonderful these cars were from the factory.
James’s Turbocharged L-series powered S30 will be back after some cosmetic upgrades. We enjoyed making some great power and music:
Rick’s BRE-inspired Datsun 240Z track car is getting a CD009 6-speed transmission, Z Car Garage Big-Brakes, coil-over suspension and track preparation.
Ken’s Series 1 Datsun 240Z (#1762) is getting our Z Car Garage Big-Brakes, ZCG CV Axles, KA24 5-speed transmission and Fujitsubo exhaust. The L28 is now receiving Jenvey ITB EFI managed by a Haltech 750:
Beau’s Datsun 280Z coming together. Fresh from paint featuring Z Car Garage Big-Brakes, Z Car Garage CV Axles, T3 suspension and more.
Taking care of clients!
Z Car Garage takes pride in our ability to handle client’s needs, with same-day service possible. Our parts room with over 1,000 parts on hand allows us to get you in and back on the road. Client Vince S had a clutch hydraulic failure and limped his way in to the shop. We sorted his hydraulics and he was off in 4hrs:
Stan K (VIN #511) and Tony H’s Series Datsun 240Z cars came in for mechanical sorting, interior work and Z Car Garage CV Axles
Datsunworks
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. You can read all about it HERE. We continue to extract more power and run longevity testing with owner Gary’s Datsun 240Z, who has the pleasure of living daily with this beast affectionately named the “Behemoth”.
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.

The New Nissan Z
Huge thanks to Nissan for giving us the opportunity to experience the 2023 Nissan Z. We really can’t wait to get our new Z!
On Saturday, September 24 we attended the Tokyo Calling 2 event hosted by Breakfast Club Rally. Z Car Garage participated with a group of client cars and enjoyed a wonderful day of driving through the foothills of Northern California. The event also featured 200 Japanese classics and 90’s-era wonders to appreciate during the morning social gathering and rest stops. Enjoy our report with mega-photo gallery and video!
Breakfast Club Rally
The Breakfast Club Rally (BCR) started just over 2 years ago. What started out as a small group enjoying weekend drives blossomed into a full-on Cars and Coffee (still unofficial) meet just before rally participants head out according to run group. The monthly BCR is always free/open to all makes and I highly recommend it for anyone looking to enjoy the beautiful Northern California roads and scenery. You can see my previous BCR reports HERE!
The initial BCR Tokyo Calling event held back in March was a success. We did not want to miss this all-Japanese, mostly-vintage rally so I assembled a group of Z Car Garage clients and friends to participate in TC2. We left the shop at 6:30am heading to San Rafael, here is a preview of our cars:
Gary’s 1971 Datsun 240Z
Rob Fuller drove our client Gary’s S30 with the Datsunworks KN20 twincam cylinder head. Supporting the 3.1L engine are our Z Car Garage Big-Brakes, Z Car Garage CV Axles, Jenvey ITB EFI with Haltech Elite management, Nissan 6-speed CD009s transmission and OS Giken 4.11 LSD.
While ZCG has performed many tests with the KN20 engine this was the first time we were able to do a 300-mile trip and really wring its neck. It just keeps getting better and better…watch the video below and turn those speakers up!
Linda Williams drove her 1972 Datsun 240Z OMS Pace Car Duplicate. Z Car Garage revived this historically-significant Z from its slumber to make it a nice driver for Linda while retaining its survivor status. She loves driving it everywhere.
Henry’s supercharged Nissan 370Z
Henry drove his Stillen-supercharged 370Z. This was his first time attending a vintage rally and he had a blast! Henry recently visited ZCG for a re-tune and upgrades, making even more power stay tuned for an update! Rolling photo by Gregory Veizades:
Mr. C, a 1970 Datsun 240Z
Our guest Herbert P piloted “Mr. C”, our stock, one-owner Series 1 Z. We put some 14″ Panasports on this time as the stock hubcaps have a habit of coming off during spirited driving!
Our morning caravan of cars enjoyed cruising up I-280 through the Golden Gate Bridge. Nothing beats driving with fellow Z car owners!
Tokyo is Calling before the Rally!
Our crew arrived at the rally start in San Rafael and it was already filled with fabulous J-Tin. BCR hosted a “social gathering” from 8-9am (usually 1 hr) so we could take in all the glorious cars. The vibe was tremendous, and as usual it went by too quickly. Let’s go through some of the highlights, with more photos in the gallery below!
Tom K’s Nissan Fairlady Z432 stunned the crowd. This rare, RHD gem is powered by the unicorn-status S20 engine:
I am always on the lookout for Nissans and Datsuns, and roadsters always get my attention. There were at least 8 in attendance including two genuine 1967 2000s. One of the most sought after Datsuns, these “half-year” models were introduced mid-1967 offering a 5-speed transmission and 150hp twin-Mikuni carb’d 2L engine…hot stuff for the era.
Ian’s SRL is #601 (out of ~1000 cars) and it was fully restored years ago by Les Cannaday in San Diego. Ian is meticulous about maintaining this car, but it is no garage queen. The (655) Off-white paint with red interior is one of my favorites. Yes, it even sports a factory Nissan hardtop with all the stainless trim!
Our client Erik drove his hot-rod R16 stroker-powered ’70. We dyno tuned this little beast recently, check it out HERE:
There were handful of Datsun 510s in wagon and sedan form. Our client Jay installed a set of our Z Car Garage CV Axles on his Green 510. Jay is a hardcore rally driver (just completing the Faultline 500) and also brought his mint wagon with family! Check out his sweet set of Devil Shadow wheels:
Our very own Nick F drove his 510 wagon and went full rally-style with intercoms:
Back to Z cars, and with many cool examples like this pair of S30s with classy Campagnolo and 432s-style wheels:
Our client Kevin’s Slicktop Z32 on WORK XD9 wheels and Stoptech brakes. A pair of clean Zenki Z31 300ZX, one LS-powered:
Leo’s Nissan Pulsar GTi-R
We were pleasantly surprised to see Leo and his Nissan Pulsar GTi-R at Tokyo Calling 2. This RHD, JDM hot-hatch is known as “Baby Godzilla”, sporting all-wheel drive and an SR20DET drivetrain. What’s wild is that this Pulsar used to be owned by our very own Gary at Z Car Garage! Leo purchased it back in 2017 and drove it all the way from Reno, NV.
Leo is an avid Pulsar fan having owned several and he really kept this one in pristine condition. He added a few upgrades including Stoptech Big-Brakes. He ven kept the Z Car Garage license plate frame!
A pair of S13 240SXs:
It was great to see our R32 Skyline clients Mike’s R32 (TE37 wheels), Miles (Rays wheels) and Kurt W. (in his GC8 Subaru) and . All will be getting zcarblog udpates:
So many cool cars please check the gallery for more photos! Next, let’s check out some non-Nissan/Datsun action…
Kei Classics
Autozam AZ-1 and Suzuki Cappuchino mesmerizing the crowd with their size and neat features:
Honda
Honda was well-represented including late model DC2 Integras and S2000s. A few NSXs, CRXs and EF/EG hatches rounded out the display:
Toyota
Supra (A60 and A80) and even first gen MR2s, turbocharged Beams-powered Celica and AE86s!
Enjoy this walk-around of the pre-rally social hour at Tokyo Calling 2:
Trucks and Vans
Let’s not forget the Japanese classic trucks and vans!
The wildest car I found was this Nissan Leaf with motorcycle engine:
Rally On!

The rally started at 9am and I was tasked with leading our group. There was no cell phone reception but I was armed with a turn-by-turn rallye printout. I enjoyed hustling Mrs. Butters through the backroads:
One of the perks of BCR events is their team of professional photographers at various stages capturing epic rolling and detail shots so people can focus on enjoying the drive. I encourage you to visit each of these photographer’s photo albums to see shots of your rides:Alex Nibyt, Gregory Veizades, Everett Lederer, and Zack Hubbell.
Arriving at Point Reyes was another opportunity to see cars I missed at the starting point. Folks took a snack/coffee break here in the quaint town. I was just admiring each vintage ride cruise by…like this Nissan Figaro!
Henry’s 370Z and an FD RX-7
After chatting we resumed the rally. This final stage was my favorite with winding roads going through Petaluma. This is where the KW Suspension, ZCG Big-Brakes and 6-speed transmission in Mrs. Butters really shine. Every gear shift, squeeze of the throttle and confidence of the brakes makes for a sublime driving experience.
The rally concluded in Tomales. Total mileage for our San Jose crew thus far was 200 miles. BCR arranged for lunch at William Tell House as their clever motto is #DoneByNoon. The intersection here was yet another car show with J-Tin everywhere. It was a superb venue to enjoy cool cars and great company.
Many thanks to the organizers, we had a blast and I urge you to register for their next event, especially if you are in the South Bay area like me and want to see what driving bliss lies North. Here are a few thoughts from Rob re-capping the Tokyo Calling 2 event:
“Loved TC2 and my favorite part is connecting with people, seeing their passion and all the other cool cars…I’m a huge Miata fan and NA/NBs were out in full force. Subaru XT…I really wanted one as a kid. Little fun fact…that rear end bolts into a Datsun 510. The Leaf with motorcycle engine was wild. Great to see our clients also on the drive. Got to see Leo and get reunited with the GTi-R, chat with Mike Young…”
“…Such a proud feeling of driving up 280 through the city and looking over to see Linda Wiliams in the OMS Pace Car, Vince S and Jim and Herb driving Mr.C. and Alex in his Sunny. The amount of community we have is tremendous. Loved how organized BCR is, so well thought out. The last 20+ years of my life I’ve been doing car meets/car adventures…the BCR guys got it down….from the registration stickers to rally directions. Little things like making sure there is enough room for folks at the meetup points…or always having clean restrooms available…these are details between enjoying yourself in a vintage car or not. The roads were incredible and scenery unreal. Sounds of L-series everywhere! Cant wait for next Tokyo Calling.”

The Drive Home
Our adventure was not over as we had to travel another 100 miles South to the shop. We caravanned back, traveling through the iconic Golden Gate Bridge and through San Francisco. I’m sure traffic had a field day with our group of Datsuns/Nissans:
At the shop, Rob gave everyone rides in the Datsunworks-powered Behemoth. It was fun to see the permanent smiles on passengers’ faces after returning:
After a full day of driving Mr. C, our stock Series 1 240Z, we gave Herbert the keys to take Butters out for spin:
Thank you to all of the Z Car Garage clients that made the journey with us. Huge thanks to BCR for extending their hospitality to our crew, everyone was thrilled. Here’s to the next rally and always, always #DoitInADatsun!
We had a great day test driving and tuning two Z Car Garage-built S30 sports cars. Here are a few brief details of each build followed by video with dyno runs and road testing. LONG LIVE THE Z!
James’ 1972 Datsun 240Z
James’s 1972 S30 At the heart of this beast is a turbocharged L-series managed by Haltech. Chassis upgrades include custom full-length subframe connectors, CD009a 6-speed transmission, KW Suspension, ZCG CV Axles and Big-Brake Kit (328mm) behind RS-8 wheels restored by Love20bee. Larry Chen featured James’s Z on this episode of Hoonigan Autofocus. Inside, a stack instrument cluster was integrated into the gauge pod, viewed from leather Recaro Pole Position seats:
Recent upgrades to “Medusa” include a new tubular exhaust manifold, intake manifold and down-pipe from from ProtunerZ. We will have more installation photos and dyno results coming soon to zcarblog.com!
Gary’s 1971 Datsun 240Z
