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.
We met Lehan in the summer of 2018 when he came to Z Car Garage with his newly acquired (KH2) 1991 Skyline GTR. After learning that these cars can be made smog compliant, he found this car locally (originally imported by our friend Sean and his team at Toprank International Vehicle Importers) and picked it up right away. We replaced the clutch and flywheel with an OS Giken TS2CD setup, replaced the rear main seal and fresh clutch hydraulics.
To fix an intermittent misfire we installed R35 coil packs ( a common RB26 upgrade) and replaced the front CV axle boots. Lehan’s goal for this R32 has been modest:
“I’ve changed the wheels and exhaust to more of my liking, replaced worn rubber parts and trim pieces, and added some Nismo bling. My goal with the car is to keep it looking mostly stock, but update the drivetrain to more modern tech, hence the Haltech ecu. In the future I may replace the 30 year old turbos but keep it to a modest hp gain, and replace the Attesa G-sensor with a digital unit. I will probably keep the HICAS system just because, and learn to drive with it on the track.”
Haltech ECU and Tuning
In March of 2019 we installed a Haltch Platium Pro Plug-in. It was set up to run MAP-based with the Haltech WB1 single channel wideband 02. We are huge fans of Haltech engine management. Rob performed street/dyno tuning tuned on 91 octane with baseline numbers of 260hp/253tq and with the Haltech making 337hp/280tq at the rear wheels:
Enjoy the dyno video!
Stoptech Big Brakes
All 90’s Nissan sports cars can benefit from larger brakes and Stoptech has got you covered. Another Norcal Skyline member Kurt W also had Stoptech brakes installed at ZCG, and he highly recommended them. Lehan’s R32 received ST40 calipers with 332mm rotors up front and ST22 caliper with 328mm rotors at the rear.
A few pictures of the brake installation:
The brakes look great behind the BBS wheels. During the brake upgrade we replaced all fluids: both diffs, tranny and transfer case.
Lehan took the R32 to a track day it performed admirably. He did experienced high oil temps, another common issue when tracking these cars. A new oil cooler will be installed next. Over all he’s please with the Skyline’s upgrades:
“Every visit to fix or update something just makes the car more awesome to drive. It feels much more lively and torquey after the tune. Best part is I can drive it as hard as I can knowing it’s been tuned safely and backed by modern engine management. It’s a similar feeling with the StopTech brakes on track – without it I would not have been able to push braking points. The steering feel and overall composure of the car is top notch, especially after the tune. I’m very happy with the car as is, but definitely looking forward to any future mods.”
Enjoying The Ride
Lehan has been driving the R32 everywhere including the track and autocross. We spotted him at the inaugural Fuel Supply Co. gathering earlier last year.
He even made it out to the Norcal Skylines Matsuri, an event we were lucky to attend 2019:
We love helping our local Norcal Skyline Owners repair, improve and enjoy their cars.
“It’s been awesome working with Rob and ZCG, and I’m really happy with all the work they’ve done. This is my first car with significant modifications, and I liked that Rob doesn’t push to have it done in a specific way. I also appreciate Rob’s effort to ensure the car is as best as it can be. I noticed some rubbing the week before a track day, and he was able to check that out on short notice, and offered to help if anything came up. True to that, I texted Rob about high oil temps the day of and he replied right away. I’m getting an oil cooler installed early Jan before the next track day.”
Thank you Lehan for your support and we look forward to working with you! More pictures in the gallery below:
On Saturday I joined six other cars for a morning cruise through the Santa Cruz Mountains. The two S30 Z cars with us were running our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles!
Glenn’s 1972 Nissan Fairlady 240z-L
Glenn Chiou drove his RHD Fairlady Z sporting our Z Car Garage Big-Brakes (for small wheels). He is an avid vintage race car driver/restorer and found our brake kit offers incredible brake feel and performance all fitting behind his favorite 15×8 zero offset Watanabe wheel:
“The most important aspect to me when it comes to braking on a street driven car is feel. Yes, stopping power is extremely important, but also is not that difficult to achieve on an early Z car that is naturally light to begin with. Feel, however, is something that has always managed to escape me and the ZCG brakes deliver. WOW, what a difference. The feel, modulation, power, sharpness was amazing. Hands down the best brakes I had ever driven on a Z car”
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 pictures of the Big-Brakes being installed on Glenn’s Z:
Glenn was having fun on the twistys on our cruise (see video below). Learn more about his Z in this Petrolicious video.
James’ 1972 Datsun 240z
James is running our ZCG BBK (1st gen, 328mm) and Z Car Garage CV Axles in his turbocharged L-Series beast:
You can learn more about this 560whp Z on Speedhunters and see it in action on Hoonigan Autofocus. James also had a blast on our Saturday cruise:
Saturday Cruising
We started our drive in Downtown Saratoga and made it to the coast via Bear Creek and Bonny Doon Rd. Here is a short video:
We were happy to enjoy the company of cool cars and cool folks, also joining us:
Dustin’s 510
We’ve known Dustin and Courtney for many years. Dustin’s 510 4-door runs a KA24DE and sweet Longchamp XR-4 wheels. The side exit exhaust is loud!
Tony’s Mazda RX-2
Tony has had this RX-2 for many years. In addition to the full restoration it now has a full (S5) 13B drivetrain with a Ford 9″ rear end! It is mint. I haven’t seen Tony in many years so it was a joy to have him along:
Lloyd’s AE86
Lloyd has a very cool collection of cars and this AE86 is the latest. Although it sports an F20C drivetrain (Lloyd promised me it’s not the same car as this one), it has numerous upgrades for a better drive. Gotta love TE37s:
Geoff’s BMW 2002
Geoff’s no stranger to our Bay Area cruises and also owns a Lotus 7. He was the only German this time with his BMW 2002 on rare Campagnolo wheels:
I drove my SR-powered ‘67.5 Datsun Roadster and it was a great way to spend the morning.
Yes, that’s a Ferrari 250 GT Lusso flying by on HWY 1!
Mike R acquired this gunmetal (KH2) 1991 Skyline GTR last August from our friend Sean 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.
Z Car Garage is familiar with the Norcal Skylines group and fellow Skyline R32 owner Kurt W. referred Mike to us in addition to an endorsement from Top Rank:
“One of my main concerns in purchasing a 25+ year old vehicle that was never manufactured in the US, was support. Who can work on this thing to perform maintenance and upgrades? I spoke with Top rank about it quite a bit prior to purchase and they had recommended Z Car garage. The car was in great condition and mostly stock when I got it. With the goal of being an all around fast street car, I started acquiring parts and placed a call to ZCG to start the first round of upgrades.”
Chassis
We discussed installing a big-brake kit, suspension, Haltech and a few others issues we handled for Mike. Here is the Project Mu 4-wheel big-brake kit:
We also installed the Ohlins DFV coil-overs, shown below are the stock R32 calipers:
With a few modifications the Project Mu kit was installed:
Some close-ups of the Project Mu setup:
We adjusted his coil-over setup and set the ride height followed by corner-weighting the car according to his weight. Further suspension mods included Whiteline Sway bars, Cusco strut bracing and SPL titanium HICAS eliminator kit. All interior panels were trimmed for a clean finish with full alignment services.
Performance
Mike was also interested in replacing the factory ECU so we upgraded to a Haltech Elite 2000 with the R32-plugin adapter. The full installation also included a wideband controller and smoke-testing the car in preparation for dyno tuning:
Greddy FMIC:
The Haltech combined with Apexi intakes, Nismo downpipe, Tomei Titanium exhaust, Greddy FMIC and PRP R35 Coil kit, netted 340hp/284tq at the wheels with Rob’s tuning on 91 octane:
Enjoy the dyno video below:
Since his last visit, Mike has added R34 GT-R Seats, and a sweet set of Volk Racing TE37 SL custom gloss black wheels (18×10.5 +15), wrapped in Michelin PS4S tires measuring 265/35/18.
Mike also relocated the battery to the trunk to make space for a Leaskspec radiator overflow tank and Radium dual catch can setup:
In addition, a Haltech IC7 digital dash was added to monitor vital engine parameters. The IC7 dash ties into the CAN box of Elite system:
More Power
Mike has been happy with the upgrades we made but like many of us the desire for more power inevitably hits:
“The car has been running flawlessly and the goal with these mods is to support the addition of a single turbo kit that Zcar will be installing this August. The turbo kit consists of a Full Race Twin scroll T4 manifold that will be mated to an EFR 8474 turbocharger. Twin Tial 44mm external wastegates will bleed off the excess exhaust gasses.”
Along with the turbo kit, we will be adding: PWR radiator, Samco radiator hoses, Tomei Type B Poncams, fuel pump, Radium fuel rail, fpr, ID 1050X fuel injectors, along with a custom intake and custom intercooler piping with a Tial q50 BOV. The goal for this round of upgrades is 500whp on low boost and 91 octane fuel.
“All of the work performed at Zcar had exceeded my expectations so far (and I’m very picky). Looking forward to the start the build and make some power of the next few months.”
We really enjoy taking care of many Norcal Skyline owners. Welcome to ZCG family Mike and thanks for trusting us with your R32! Enjoy The Boost until you return!

Last week we had the pleasure of dyno tuning Eric Straw’s magnificent 1969 Datsun 2000 Roadster. Eric is a long time friend of Z Car Garage and we first dyno’d this roadster in 2012 while a few years later we enjoyed tuning his RB26DETT powered DR30 Skyline. In addition to being a talented fabricator it is clear that Eric has a penchant for white paint, red valve covers…and turbocharged Nissan powerplants!
SR20 Roadster: Version 2
After restoring his roadster with an S13 SR20DET drivetrain a decade ago, Eric started working on the next evolution with a totally revised chassis and new engine (the previous setup sold for a customer’s roadster). The new drivetrain consists of an S14 block (JE pistons, K1 rods, P12 oil pump) with a P11 VVL head (Kelford turbo cams, Tomei cam gears, Taarks VVL relocation kit, R35 coil packs) all mounted to the roadster frame using a Spriso Motorsports HD motor mount kit.
Providing boost is a GTX3071r turbo with Tial exhaust housing mounted to a Straw-fab’d custom tubular manifold with CNC 1 piece collector. On the cold side is a custom intercooler with Garrett core and custom intake manifold. It’s both pretty and functional considering the roadster’s tiny engine bay:
Backing the SR20VE-T is a 6-speed (CD009) transmission normally seen in the Nissan 350z. The SR mounts to the tranny via a Mazworx bell housing with an OS Giken Twin disk. The shining star in Eric’s craftsmanship is the chassis preparation with a heavily modified frame with tubular x-member and bolt-in reinforcements.
It would take another blog post to dive into the suspension but if you are curious about the restoration and more please check out Eric’s roadster featured in this Speedhunters article by Naveed Yousufzai HERE.

Dyno Tuning
The tuning session was conducted with driveability and longevity in mind. Outright peak power numbers were not a priority. Eric’s hometown in Salem, Oregon is where this car would be enjoyed with premium fuel and the occasional 100 octane splash. Surely more power could be extracted with E85 but Eric is 50 miles from nearest station. Rob comments on the choice of engine management for the SR20VE-T:
“When Eric contacted us about about building the SR20VVL we discussed EMS, and ZCG is a Haltech Pro Tuner. We really like how user-friendly this product is for a tuner. It’s perfect when you need to map out all of the different phases, complete control of ignition/fueling, cam control, idle air…everything to take this car you’ve dreamed of and make it drive like it came from an OEM factory.”
Rob dyno tuned the SR equipped with a Haltech 1500 Elite. Initial passes were performed on 92 octane. The plots below show without a boost controller (387hp/287tq) and with a boost controller, making 425hp/331tq to the wheels:
Of note is Nissan’s wonderful variable valve timing (VVL) at work with a very flat torque curve and incredible, spine-tingling cam changeover sound. See video below! Eric and Josh drained the fuel tank to add 100 octane for the next passes. Fueling is supplied by a custom stainless tank (Aeromotive hangler/bladder), custom stainless lines all dash 6, 1300x Injector dynamics and a Radium Fuel rail:
On 100 octane the SR20VE-T made 491hp/393tq at the wheels. That is roughly 570hp at the crank. Keep in mind this little Datsun roadster weighs 2250lbs with a hardtop and 14 gallons of fuel!
Driving Impressions
Following the dyno session we had to take the roadster out for a drive. This video shows multiple dyno passes and test drives, volume up!
Here are a few driving impressions from the three of us, enjoy!
Eric
“The car went from being an impressive car to completely coming alive and becoming a rocket ship that just keeps pulling. The VVL is like another level of performance. The power comes on very progressive and linear to give the chassis the best chance of getting as much as possible out of it. We made multiple setting to help with driving goals based on the roads and situations we are in.”
“The suspension has been a lot of work and has really paid off many times over be able to get this power to the ground and drive the car like it was intended. The rear suspension is so predictable and precise that immediately I had a lot of confidence to be able roll some power out of the corner. Rob had truly made this dream come alive and make this car so very impressive.”
Rob
“The cam control and air flow from the VVL is staggering, just really super cool. I’m not surprised…from being around the DR30 and seeing all the cars Eric and Michael Spreadbury have built over the years. This roadster continues to evolve as they continue their craft with each chapter revealing a new level like a boost controller: 5 years ago was 10lbs of boost, 2 years ago 12lbs, and now 22lbs (this roadster should only be driven on high!) Eric Straw isn’t just one man. He seems to be a mass of people to not only design an engine bay and make it work efficiently but also bolt a non-matching transmission, and then that rear end suspension….obviously one of the biggest things when modifying a 50+yr old Datsun with high power levels is trying to put it down. His engineering accounted for enough tire, brake and balance. The setup Eric built for this roadster I could not believe how we could deliver 500+hp/almost 400ftlbs of torque, and yes we were lighting off the tires but…I still felt like I was in control. We were on ice, but I felt like I was on Speedvision from back in the day of World-rallying Championship..with just a slight motion of the steering wheel I could rotate that car wherever I wanted.Â
Alvin
“As a passenger and long-time roadster owner…it’s not easy for me to ride shotgun in a high-powered car but I still can’t fathom how smooth it felt under intense acceleration. These are super tiny cars and to see both Eric and Rob harness it was a testament to Eric’s chassis engineering. I’ve been in other Datsuns with turbo SRs and they will pitch sideways under full throttle but this one was planted even on our rough downtown roads. Watch the video. It’s epic.”
All of us concluded and shared similar sentiments: Eric’s suspension enabled this roadster to manage all that power. When boost hits and the tires break loose it can be seemingly glide controllably with steering input…no hopping or skittering. The rear suspension consists of a hybrid rear axle built by Moser based on a Dana 44 with a Torque arm and 3-Link Watts with Ridetech coil-overs. Up front are custom Ridetech coil-overs and sway bar. R33 GTR Brembo brakes provide stopping power. The Watanabe wheels are wrapped in 225F/245(!)R tires which are massive for a stock-flared roadster body.
We had blast spending the day with Eric and tuning his roadster. We can’t praise him enough for the ingenuity and execution of his build. Eric would like to thank Julie Straw, Michael Spreadbury and Rob Fuller. More pictures in the gallery below and Enjoy The Boost Eric!
