Over 30 years ago OS Giken created the first dual overhead cam (DOHC) 24-valve cylinder head for the Nissan L-series engine: The TC24-B1Z.

Z Car Garage in partnership with OS Giken debuted the first North American (LHD) Datsun 240z to run the TC24-B1Z at the SEMA show in Las Vegas, CA last week:

What Happens in SEMA . . .
Every year the Specialty Equipment Market Association (SEMA) takes over the 3,000,000 square feet of floor space at the Las Vegas Convention Center for a weeklong trade show that covers everything automotive. Exhibitors feature cars, trucks or SUVs in their displays to showcase their products or simply to attract attention. In a town where weird is normal, the masses of over-the-top and extremely modified cars seem at home inside the multi-building center.


Tens of thousands attend the SEMA Show each year, and while a trade show and not open to the public, it’s the one auto show every enthusiast wants to attend. Despite the propensity for depravity that comes with a no-last-call town, SEMA is never anything short of a legendary gathering and we had a blast during our 2-day visit.



SEMA 2015 marked a special milestone for the crew at Z Car Garage as we prepared a special 1971 Datsun 240z for display at the show.  Through an exclusive collaboration with OS Giken we unveiled the world’s first North American (LHD) S30 to be powered by the legendary TC24-B1Z engine. This mythical twincam cylinder head bolts onto an L-series block giving it crossflow breathing and high revving operation.

The Z was well received by show goers stopping by the OS Giken booth which featured video displays of the engine being assembled and tested at ZCG. Jaws dropped at the sight of the TC24 and we also heard admirable reviews from fellow Datsun/restorers for the build. Our friends at Japanese Nostalgic Car (JNC) and Speedhunters featured the car in their SEMA reviews:



The lucky owner of this OS Giken-equipped Z is our friend and customer Gary Stephenson. In short, his build highlights our restorative powers and sports full suspension (allowing 255/40/17 tires under stock flairs), our ZCG Big Brake Kit, nos OEM glass, integrated roll cage,  KA24 transmission, Recaro Competition seats and more.




In current tune/configuration the TC24 produced 376hp/281tq to the wheels on 91 octane, proudly displayed by the car at SEMA. This Z will be driven on the street and track so stay tuned for videos!



Huge thanks to the crew at OS Giken for a killer booth and memorable experience. Look for an in-depth story about our collaboration with OS Giken and TC24-B1Z build on the blog soon.  Long Live the Z. Here comes the TC!



Datsuns Everywhere at SEMA!

Our favorite vintage cars were in great numbers this year. One of the most prominent of course
was Sung Kang’s 1973 Datsun 240z affectionately called “FuguZ”.


Sung ( “Han” of Fast and Furious movie fame) chronicled the build through social media, enlisting parts from around the world with final assembly by Kenji at Greddy. Sporting the latest Rocket Bunny body kit, Volk TE37s and an ITB’d RB26 drivetrain this was a crowd favorite and inspiration to all. Congrats to Sung and the Greddy team for an epic build!


For the first time in SEMA history a Datsun roadster was on display courtesy of Socal specialist Kevin Desirello.


This fully restored 1967 SPL311 was treated to a complete S15 SR20DET drivetrain swap but Kevin and his team didn’t stop there. By adding a VVL head and punching the displacement out to 2.2L, they essentially made an SR22VE-T with power levels of 450whp anticipated!



Garret wanted the car for its SEMA booth and it was placed alongside the famous Mad Mike Whiddett’s insane twin-turbo FOUR-rotor powered Formula-drift Miata. We are especially proud of Kevin and his roadster for making it to the Top 21 in The Battle of the Builders competition!



This Datsun 520 pickup was actually a contender in the Optima Batteries challenge with a Mazda Miata drivetrain and double A-arm suspension F/R!


Hakotora! Take one Sunny ute and graft a Hakosuka front end on for a mean little pickup. This build had some great details and a built SR20DET under the vented hood.


This BRE 510 was on display in the Tokico booth. A celebrity driver car, this is now owned by Datsun-freak Adam Carolla. Our hero Pete Brock was not too far from the dime!


Eric and Josh from JDM Legends made the trek from Utah and displayed their superbly restored Ken and Mary Skyline. The C110 had all the choice parts from the triple-carb’d L-series, Comp seats and Watanabe wheels.


There’s a New Boss in Town . . .

Not Datsun per se, but the following Nissan 240sx (S14) sports cars all have one thing in common: The “Boss” aero kit from RocketBunny/TRA Kyoto. The kit transforms the front end of an S14 into a B110/Challenger looking vehicle… it takes some time getting used to, but we dig it.

by Alvin G @ 12:14 pm on November 1, 2015


Patrick Chio continues to race in the US Touring Car Championship (USTCC) with the Speed SF/ Z Car Garage Nissan 350z.  The events are televised on Final Drive TV with some great commentary and white-knuckle action!

Screen Shot 2015-11-01 at 10.01.41 AMScreen Shot 2015-11-01 at 10.00.52 AM

Round 3 was held at Laguna Seca and Patrick started on the pole! Patrick finished 5th and had a DNF, videos below:



“I qualified pole position in Touring Car class. However, a slow start caused me to fall back to the 7th position. Climbed up to 4th and spun out due to oil on the track at 18:50 mark in the video.”



Round 6 was held at Sonoma Raceway and Patrick captured a 2nd place finish!!!. It was a very close battle with a very experienced pro driver. We will post the video soon. For now, check out this short recap from


“Sheehan, driving the / UTI / Konig Wheels Hyundai Genesis Coupe, thought he had the race in the bag after built a five second gap after the first lap but Patrick Chio, driving the Speed SF / Z Car Garage Nissan 350Z started clicking some fast laps and by lap 7 was less than half second behind. Sheehan had to drive as hard as he could to pull out a win. After the race Sheehan said, “I left nothing on the table. That’s all I had.” Finishing in third place was Justin Crickenberger in the Hawk/ Competition Clutch/ Sparta BMW M3.”



We are very proud of you Patrick!  If you missed it catch Round 1 and 2 results HERE

Proper Nismo: Rasheed’s 2015 Vortech Z

We love the latest version of the Nismo 370z. In fact this is the aesthetic that should have been released from the start! Although the Nismo Z has improved cosmetically the drivetrain still summons the same 350 horses and 276 lb-ft of torque it has offered since the package first appeared in 2009(!).

Power junkies need not fear, Z Car Garage is here to help. With only 22k miles on the odometer, Rasheed B came to us with his stunning 2015 Nismo Z finished in Pearl White for a full Vortech supercharger kit.

How does it perform?

Bone stock from the factory, the Z put down 295hp/242tq. The Stillen supercharger added 84hp/58tq to the wheels with the kit-supplied CAN tune:

Rob’s tuning yielded even more power with final numbers of 420hp/320tq, improvements of 125hp/78tq over baseline.

This Nismo 370z now has more power to back up those aggressive looks! Enjoy The Ride, Rasheed!
