Performance With Passion”These are words that describe our work at Z Car Garage and we are passionate about making your Z perform as good as it looks. Photographer Larry Chen commissioned ZCG to transform his beloved SR20DET-powered 1970 Datsun 240Z from an “ok driver” to a no-excuses, multi-dimensional sports car with power, handling, braking, comfort, reliability and performance to match its eye-catching beauty.

 

Join Rob and Larry as they share the story of Larry’s Z, affectionately called “Ole Orange Bang”, featuring our Z Car Garage Big-BrakesZ Car Garage CV Axles, chassis preparation, dyno tuning and more. Enjoy the videos with behind the scenes footage and photo gallery below!

 

Build History

 

Car enthusiasts and motorsport fans recognize the name Larry Chen as the greatest automotive photographer. Larry has made a career out of his passion for capturing the right moments in racing. We are huge fans of his work since the days of covering Formula Drift, time at Speedhunters, and recent work with Hoonigan Autofocus. Our favorite Larry Chen moment is his photography of Ken Block’s 1400hp Hoonicorn at Pike’s Peak for the filming of Climbkhana.

 

Larry Chen is regularly exposed to some of the coolest builds across the globe, so you can imagine our joy hearing that Larry’s personal car is a Datsun 240Z. Larry’s Z is a Series 1 (VIN# 2868) that he purchased on his 21st birthday for $3000. He started autocrossing immediately with his buddies circa 2006, and it became an integral part of his life:

 

“It’s been such a big part of my adult life, and it will continue to be a part of it for the rest. The name actually came from a Mexican drink that we love in SoCal. My car is Orange and it backfired a lot when I got it especially when I was low on gas. So it was only appropriate to call it Orange Bang. On my wedding night instead of being ferried away in a fancy limousine, I drove my beautiful wife home in the Z, after some wedding burnouts.”

 

Following years of autocross and track use, in 2013 the tired L28 was replaced with an SR20DET straight out of a former Formula Drift car.

 

Like many enthusiasts, Larry continued to modify and upgrade the Z to fit his needs…adding A/C, coil-over suspension and creature comforts along the way. We spotted a freshly painted Ole Orange Bang at the 2019 Japanese Classic Car Show:

“In 2019 my friends at Bells and Vaughn in Pasadena, California did a full ground up restoration. It has all new paint and it was taken all the way down to the metal. Just this month I picked it up from Z Car Garage in San Jose California. ZCG pretty much went through the entire car and they fixed everything that was mechanically wrong with it.”

 

When Larry Met Rob: A ZCG Story

 

We first met Larry when he visited us at the 2018 Japanese Classic Car Show in Long Beach, CA. We talked about Z cars, and how he really wanted to get our Z Car Garage Big-Brakes and ZCG treatment on his personal Z. In 2020 he trailered his Z up from LA to ZCG in February, literally a few weeks before the pandemic.

“I actually found out about ZCG on Instagram and met Rob for the first time in SoCal at JCCS. I inquired about getting brakes for my car since it couldn’t stop even with a Toyota 4×4 conversion and Nissan Maxima rear disk brakes. They were absolutely horrible. There is a reason why people ship their Z cars across the country to ZCG. The passion is there and you can see it on everything they touch.”

While visiting Z Car Garage Larry featured a few of our client cars and did a shop tour for his YouTube channel Hoonigan AutoFocus. You can click on the thumbnails below to watch the videos:

 

Fast forward a year later and Larry returned to pick up his beloved Z. He shot a few more vehicles like my my 1967 Datsun Roadster and Randy’s 1970 Salt Flat Racer but most importantly Larry finally filmed a 1hr-long Hoonigan Autofocus episode of his own Z, Ole Orange Bang. Larry was so happy with his Z he recorded a separate lock-down video for our friends at Haltech.

 

We couldn’t leave our readers hanging without our own ZCG-style feature complete with dyno videos and behind the scenes footage, so if you can’t wait any longer here it is below. Turn those speakers up and enjoy, read on for an in-depth look at our work.

The ZCG Touch

 

Larry and Rob developed a plan for Ole Orange Bang. The Z had past work performed by many folks including Larry’s buddies. We simply wanted his Z to be a multi-dimensional sports car with power, brakes, handling and comfort. Cosmetics were already handled, it just needed some mechanical love with ZCG-products that you will find on many of our ZCG builds. Let’s begin with the chassis upgrades, then go into dyno tuning/engine bay work and final details like the interior and weatherstripping.

ZCG Big-Brakes and CV Axles

We handed Larry the keys to “Mrs. Butters”, our 1971 Series 1 240z shop demo car and he was sold on our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles! Butters has a way of doing this to our clients 🙂 Read below for a brief description of these parts:

    
As fellow S30 owner/racer Glenn C mentioned in his review, on top of braking performance, pedal feel is extremely important and our Big-Brakes deliver. This is a direct result of working with engineers at Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments. All fitting behind a 15″ Watanabe or Panasport wheel (and some 14″ wheels) and retaining factory emergency brake lever! A few details below:

Calipers: Stoptech ST42 4-piston front & rear race calipers (Alum 6061 mil-spec Type III anodized)

Rotors: 280mm x 20.6 with Alum 7075 hats

Pads: Stoptech 309 sport street pads

Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE.

A few closer detail shots of the calipers, rotors and hardware:

 
 

We removed Larry’s existing Toyota 4×4 front calipers and rear Maxima setup and installed our ZCG Big-Brake kit front and rear:

 

He got a new, OEM brake master cylinder as well:

 

At the rear, the Maxima setup was replaced with our ZCG Big-Brakes. Factory handbrake functionality IS retained!

 

Larry was impressed with the braking performance:

“The ZCG brakes and axles really give the 240z an update with modern top of the line performance where the Z badly needs it. These cars are lightweight and easy to make fast, but everything else that goes along with it is very lacking. While the 240z is a great car to drive in stock form, there is nothing like having a lightweight turbo rear wheel drive sports car.”

Z Car Garage CV Axles

Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. We have over 140 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 
 

Larry has CV Axle set #328. Stock half shafts (L) and ZCG units bolted in to the Subaru STi LSD diff. The stock suspension parts had been long replaced with Techno Toy Tuning parts. Larry does not have to live with those loose CV axles anymore!

 
 

More pictures of the ZCG axles installed, we will discuss the KW coil-overs below:

   

Wheels By Love20bee

Complementing the new Big-Brakes and suspension on Larry’s Z are a fresh set of Southern Ways Epsilon mesh wheels from Love20bee. It was an absolute pleasure working with owner, Matt K. to adjust the offset on the wheels just before Larry picked his Z up from ZCG.

 

We wanted Larry to be able to use the KW Suspension and ZCG Big-Brakes to their full potential and put all the power down effectively without clearance issues. The offset was a bit too aggressive causing fender rubbing and excessive camber reducing the contact patch of the sticky Yokohama tires.


Larry’s Z already had a set of KW Coil-overs. Not to be confused with our ZCG-labeled KW Suspension with adjustable rebound and dampening that we’ve developed over several years (releasing soon). We adjusted Larry’s KW’s for best ride and corner-balanced the car using his weight. With the wheel barrels adjusted and suspension aligned Larry can now throw this Z into any corner with confidence. No rubbing, no excuses.

 
 

 

Engine


Larry had a long list of problems he needed resolved with the drivetrain. The SR was running an older AEM standalone setup for racing duty so it would drive roughly on the street: poor cold/hot starting, erratic idling, stalling on deceleration, overheating and the A/C wouldn’t blow cold under hot conditions. Before sorting these issues we cleaned up wiring and hoses in the engine bay. Here is what the cooling setup looked like before:

 

The oil cooler was mounted in front of the intercooler and there was a small deflector plate placed across all heat exchangers. We re-designed the ductwork with help from TCDesignFab to seal the intercooler/AC condenser/radiator to direct air flow and eliminate heat soak. Serious SPAL fans were added to a new Mishimoto rad:

 

The oil cooler was relocated below the FMIC:

 

With air now directed through the heat exchangers the SR operates well under heat soak conditions, even with the A/C on and blowing cold. Even though the SR20 isn’t Rob’s first choice of engine swap it works really well, looks awesome and makes great power. Speaking of looks, we couldn’t resist adding our body-color matching valve cover (like Rob’s 510 and Rb-powered Z cars):

 
 

Hardware was removed and re-plated throughout, more pics in the gallery!

 

Dyno Tuning

We are huge fans of Haltech engine management. We use their Elite line of ECUs exclusively on our EFI engine builds and Larry’s SR received an Elite 1000 unit, mounted on the passenger foot well. Rob dyno tuned the SR20DET using Haltech. Baseline was 245hp/223tq and with Rob’s tuning it made 295hp/277tq at the wheels:

 

Larry was absolutely blown away by the performance, response and night/day improvement in drivability. Beyond peak gains of 50hp/54tq at the wheels, much of the increased response can be seen in the huge area under the curve from proper wastegate operation. Haltech is so user friendly and the benefits are priceless. You can see the dyno runs and road testing with Larry and Rob in this this video.

 

Interior

 
 

After driving our client James Stephens’ turbocharged 1972 Datsun 240z for an episode of Hoonigan Autofocus, Larry knew right then he had to have a set of Recaro seats for Ole Orange Bang. We removed his old seats and installed a new set of Recaro Pole-Position seats. He loves them:

 

Any bodyshop can install weatherstripping but Larry really wanted ZCG do tackle it and we happily obliged. One of our favorite upgrades to the interior of an S30 is our ZCG sound deadening package. Usually found in our full-blown ZCG restorations, the result is a less tinny sound and almost Germanic-like “clunk” when you shut the doors. We also refurbished his window tracks to ensure smooth operation:

 

We are really proud of the HVAC system in this Z. Larry mentioned the A/C wouldn’t blow cold..we tested Larry’s A/C after our ducting upgrades and it blows cold even after full throttle applications and heat soak.

Details

 
The little things are what we excel at. A common problem with Series 1 cars is exhaust fumes entering the car through the hatch vents and tail lights. We replaced the hatch and tail light seals and sealed the hatch vents. No exhaust smell in the cabin. (below) It made us happy when Larry called out these little details while filming…an OEM Nissan oil filter and re-plated hood latch hardware:

 

Please check the gallery below for more detail shots, there are too many to list in this blog post!

Enjoying The Ride

 

Larry picked his Z up from Z Car Garage in February of 2021. He immediately started enjoying Ole Orange Bang by driving to various events and gatherings in SoCal. We were so stoked to see him happy with his Z again.

 

Getting updates from Larry was rad:
“It finally performs as good as it looks! Rob and the team are so detail oriented. They know these cars inside and out and my car has never driven so well in its lifetime. I can’t wait to bring it back for some more goodies.”

We were reunited with Larry and his Z at this year’s Japanese Classic Car Show at the Anaheim Stadium. The Z was on display in the Leen Customs booth where fans could get his autograph:

 
 

Orange Bang with FuguZ and Medusa. We are beyond happy to have our Z Car Garage chassis parts on these high-profile Z cars.

 

As happy as we were to see Larry driving around SoCal what really made our day was seeing him drive Ole Orange Bang in anger at a local autocross event! He put our Z Car Garage Big-BrakesZ Car Garage CV Axles, suspension and dyno tuning to work:

“I decided to take a personal day and do a bit of driving for fun. I haven’t auto crossed in almost 15 years. I went to the CornerExit auto-x at California Speedway and it was an absolute blast. Orange Bang held up amazing, and everything @zcargarage did to it paid off. I ended up getting 2nd place in mod class!” 

 

We will have video of Larry ripping through the autocross on our Instagram story. For now, don’t miss the video we made of the Z in action here:

UPDATE 6.30.23

Larry just dropped an amazing video about his Z including its history and canyon driving, enjoy!

Thank You Larry!

Our journey with Larry is just beginning. Thanks for entrusting Z Car Garage with your Z and believing in us. We appreciate all that you do for automotive culture and your work is inspiring. Always Do It In A Datsun and LONG LIVE THE Z!

Henry’s Stillen Supercharged 370Z

Filed under: 370z,Featured Cars and Projects,Performance
by Alvin G @ 5:10 pm on April 16, 2021

 

We met Henry L in 2019 when he brought his 370Z in to Z Car Garage for bolt-ons and eventual forced-induction. Henry is a fellow gearhead with an Alfa Romeo 4C spider but his passion for the Z started at an early age:
“My first dream car was 350Z. I learned about Z cars in my college days and I recall a cool kid driving one while I was waiting at a bus stop in the cold rain. We had an opportunity to buy a new car and I was very fortunate that it could be a Z. After purchasing the 370Z, 6 months later went to ZCG and the journey began. No offense to stock Zs but these are meant to be modified 🙂 My wife and I both love our Z and I thank her for  supporting my hobby 🙂 “

 

Bolt-on Beginnings

 

With only a few months of owner-hip of his new 370s Sport Touring Henry visited us for upgrades. The latest Z34s had ECU changes and no software support at the time. Henry knew he wanted to go forced-induction so in the interim we started bolt-on upgrades. In April of 2019 the chassis was treated to full KWV3 coil-over suspension with SPC F/R control arms and Hotchkis sway bars:

 

A few installation pictures, followed by a full alignment:

 

A cat-back exhaust system from Armytrix with Valvetronic sound adjustment:

 

Henry requested a new steering wheel install:

 

Stock (with a cover) removed and new carbon fiber + alcantara-trimmed wheel installed:

 

Time For Boost

 

With 12k miles on the odometer Henry was ready for boost. We ordered the Stillen supercharger kit (black), CARB-legal for piece of mind. Supporting parts included a Concept Z 25-row oil cooler (thermostatically controlled), Stillen transmission cooler and fueling upgrades. Here a few pictures of the installation:

 

Fueling upgrades include a CJ Motorsports stage 1 fuel return system and billet fuel pump hat, 1300cc Injector Dynamics injectors, Hellcat Wallbro fuel pump, SpecialtyZ flex fuel kit:

 
 

The SpecialtyZ flex-fuel kit comes with a Zeitronix gauge that we mounted in pace of the OEM clock:

 

Cooling upgrades include Soho Motorsports air-to-air intercooler, Concept Z 25-row oil cooler (thermostatically controlled) and Stillen transmission cooler. Also shown is the Fast Intentions crash bar with tow-hook:

 

Oil and transmission coolers:

 

We installed a Fast Intentions billet flex-plate, much stronger than the OEM unit:

 

Finally, we changed the exhaust from Armytrix to an ARK Grip setup paired with ART Pipes from Motordyne:

 

Henry loves the current exhaust setup:

“I’ve gone through Nismo OEM, Armytrix, and eventually settled with Rob and a friend of mine’s suggestion for the forced induction route: Ark grip catback system + Motordyne art pipes = the deep growl without screaming. Sort of the centered idea of the goals of my Z project – subtle power without drawing attention.”

 

Dyno Tuning

 

We wanted the most efficent blower wheel to run ethanol so the V3 SI blower wheel was installed. Ecutek software  was used for tuning, MAP-based with omni sensor.

 

Shown below are dyno graphs from when Henry was NA to 91 octane and E75 tunes on the Vortech. NA, the Z made 316hp/252tq and a 91 octane tune supercharged yielded 501hp/370tq at the wheels:

 

Rob then tuned the Z on E75 for 573hp/426tq at the wheels:

 
 

Enjoy the dyno tuning video!

 

We are very happy with the results and even more stoked to hear Henry’s feedback on the supercharger and tuning performance:

“The supercharger is very daily usable and power whenever I want!  The sc mods put together and tuned by Rob for a 7at Z is able to reach 570+ whp and 430 wtrq and still feel smooth and dramatic at the same time is absolutely beyond my expectation (I followed every ZCG 370Z blog posts and it’s a honor to be one of the highest power 370Z from ZCG, hats off to Rob) And did I mention daily-driveable? Good surprise for me. In addition, Rob has been really patient and knowledgeable for all my questions and requests and late night text regarding my Z. It really felt like we built the car together but it’s all his magic touches! I really appreciate the journey! More to come”

Wheels Make the Car

 

We have said it before: wheels make or break a car.  After long discussions with Henry we decided on the Ray’s TE37 Ultra Track Edition II. Finished in Blast Black and sized 19×9.5/10.5 these wheels look perfect on the Z34.

 

We love the little details Ray’s applied:

 

Enjoy The Boost!


Henry has been Enjoying The Ride in his supercharged 370Z.

“I love my Z and ZCG! Long live the Z! ZCG has been the place to go if you love Z cars, new or classic. Rob and the shop/crew exude passion for Z cars and you immediately know they will take care of your Z and your Z will be among its family. Rob has been great through the journey and worked with “our” Z. I am sure there is more to come for my Z with ZCG!”

 
 

You can follow Henry here on Instagram. What’s next for his Z? He’s playing with idea of a body kit but trying to maintain that subtle-aesthetic approach in his build. Stay tuned! Thank you Henry for letting us build your Z. It’s very cool for us as a shop trying to make 50-old cars keep with cars like this. We enjoy playing with the new stuff just as much as the classics. LONG LIVE THE Z! More pictures in the gallery below:

EVENTS: DWA Rally From Home South

Filed under: 240z,Events,Featured Cars and Projects,Great Drives
by Alvin G @ 5:10 pm on October 5, 2020

 

The 2020 Rally From Home South was held October 1 and we had a wonderful driving experience. Hosted by Driving While Awesome, the one-day event brought interesting cars and their drivers sharing a common passion for enjoying the best driving roads in Northern California. We participated with the Z Car Garage 1970 Datsun 240z and this is our report from the day filled with open roads, seemingly endless stretches of curvy mountain passes and good company.

The ZCG Datsun 240z

 

Rob handed me the keys to “Mrs. Butters”, our 1971 Series 1 240z that serves as the shop demo car and I happily obliged to drive. While this S30 deserves its own feature, here are a few details on the build:

Engine: 3.2L L-series with triple Mikuni 44 carbs and ZCG Heat Sheild
Suspension: Full KW coil-over suspension (ZCG-spec)
Brakes: Z Car Garage Big-Brakes
Drivetrain: Nissan CD009a 6-speed, Z Car Garage CV Axles, OS Giken 4.11 LSD
Wheels: 16×7 Panasport with 225/50/16 Toyo Proxes RA1
Interior: Recaro LXF seats

 
 

The Z performed admirably without a single problem over the 300+ mile event. This is a testament to thorough rally-prep (thanks ZCG crew) and the wonderfully upgraded suspension/chassis. These modifications offered a great balance of ride compliance and stiffness for the canyons with a seamless transition between rough to smooth surfaces. The ZCG Big-brakes also delivered great feel and zero fade…truly confidence-inspiring. Icing on the cake was the Nissan CD009a 6-speed transmission :

 

This gearbox completely transforms the driving experience in Butters. Gone are the long throws of the close-ratio ZX 5-speed and any feelings of fragility with high-speed shifting. The 6-speed simply clicks-off shifts with minimal effort and the gear spacing is truly a match made in heaven for the L-Series. More details with full testing (weights/dyno etc.) coming soon. Enjoy this video of Ms. Butters and hear that L-series sing!

 

 

Rally Start: San Juan to Coalinga

 

With the recent fires and COVID changing how we live, the typical 3-day format of previous DWA rallies (CRR Rewind 2019) was changed to a one-day event. I really enjoyed it and though a single day sounded appealing I did miss the extra driving and mingling of former events. This year the rally was dubbed Rally From Home South, as the start was very close to the South Bay Area. I joined fellow enthusiast Geoff W in his 1972 BMW 2002 Monday morning to blast down to the starting point in San Juan Bautista, CA.

 

The mini-cars and coffee of rally participants was full of wicked metal, both old and new.  The DWA organizers encouraged us that this isn’t a race, and to enjoy the roads at our own pace. I can’t emphasize enough how great this group of folks is. A good portion are DWA-veteran rally drivers and the positivity was contagious. We were the only Datsun/Nissan represented!

 
 

Geoff and I grabbed our swag bags and rally maps and hopped into our cars heading South through HWY 25. A few brief stops along the way, at Condon Peak (Ron’s S2000) and oil fields in Coalinga:

 

King City to Fort Ord

 

The next stages leaving King City were a mix of long sweepers with a few technical sections.  Despite the smoky sky and blistering heat we made it to the Green Bridge. Here, Geoff and I took a nice break under some trees. Soon we were joined by Naveed, Brendan, Marcelo and a few others!

 

Carmel Valley Road to Laguna Seca

 

This was my favorite stretch of road on the rally. We enjoyed it so much that we turned around and drove it again, while capturing some video of the cars in action. While Geoff and I were putting in work wrestling our vintage cars, Naveed was comfortably living the dream in the Porsche GT3RS from Abrahim of StealthLabs:

 

It is difficult to describe the driving experience through photos, so please enjoy this video I made!

 

Geoff and I switched cars for a bit. I was really impressed with the 2002’s handling, it’s a gem. The rare Camapagnolo wheels also look incredible with the sticky CR65 tires. We arrived at the entrance to Laguna Seca and it was another car show representing a great feature of DWA rallies: diversity. So many cool cars from all era’s and marques! This was a fun time chatting with fellow rally’ers

  
 

Our final stop was a relaxed gathering at Fort Ord under a filtered sunset.  A great way to end a day of driving. More picture in the gallery!

 

Thank you DWA!

 

Rally From Home South was a surreal experience. I am still day dreaming about the incredible stretches of roads that we travelled all in one day. For what seems like a brief moment in time we were transported to another world with changing landscapes, smells, sights and sounds.  Big thanks to the crew at Driving While Awesome and old/new friends met during the rally. We are definitely signing up for the next event! Enjoy the picture gallery below and LONG LIVE THE Z!

TE Tuesday: Kurt’s R32 Skyline GT-R

Filed under: Featured Cars and Projects,Performance,r32
by Alvin G @ 2:12 pm on August 27, 2019

 

Kurt W is a Nissan enthusiast having owned a 350z that we worked on back in 2008.  Last year he acquired this (KH2) R32 Skyline GT-R from our friend Sean Morris and his team at Toprank International Vehicle Importers. It goes without saying, if you are in the market for a vintage Skyline (or any JDM car) IVI is the place to go.

 

Kurt visited Z Car Garage for minor sorting and a series of upgrades we will document in a future blog post. Recently he came in for installation of 17″ VOLK TE37V wheels with Bridgestone RE-71R tires:

 

The wheels frame the Stoptech Big-Brake kit( 332mm front and 328mm rear) nicely. Love the dish on these!

 

Electric Avenue

 

Kurt also called us about lowering his Tesla Model 3 and for the first time an electric vehicle came to ZCG for modifications. A full KW coil-over suspension setup from MountainPass Performance was installed:

 

The Model 3 received a full alignment. Note the weight/distribution!

 

Kurt’s R32 will be back at the shop for some exciting power upgrades stay tuned for a full report!
