We have known Alex for many years and enjoy seeing his Sunny truck on local drives and gatherings. He reached out to Z Car Garage for dyno tuning and we happily obliged. The Sunny was already close to being dialed-in so we just put the sprinkles on with a few adjustments. It is such a cool little RHD truck and drives really well.

 

Alex’s cars are built to high standard and have a great vibe. His LS-powered Datsun 510 wagon built by Marcus Fry Racing is well-known in the community:

 

“I met Rob through a mutual friend at the time (Dan from DGR), just about 15 years ago. I helped deliver the Bluebird he has around that time. Throughout the years I have heard great things about ZCG and it only made sense to go to Rob when it was time to get the carbs tuned on the Sunny. My experience was great. The acceleration is now smoother and I got to see numbers. The carbs are now synced and timing adjusted.”

 

Alex recalls how acquired the Sunny:

“I randomly found the Sunny for sale in Seattle a few years ago and pulled the trigger as I have always wanted one but never seen one in person. It was originally brought to the states by JapaneseClassicsLLC a year prior. A good friend, Marcus of MFR, volunteered to go with me and tow it back. Since then, I have had a blast driving and updating as we all do when we get a Datsun to play with. Rebuilt 5-speed, 0 offset Panasports, new rubber bushings and weatherstripping, and getting the seats reupholstered are just some of the things I have had done to date.”

Dyno Tuning

 

Alex brought truck to ZCG and we got it on the dyno. Under the hood is Nissan’s 1.2L A12 engine, also used in the B110 series sedans/coupes. This one sports dual Solex-Mikuni induction. It was already close to being dialed so we adjusted the full throttle, smoothed-out the fuel curve and timing. The truck made 54hp/59tq to the wheels:

Enjoying the Ride

 

We love that Alex drives the ‘Ute everywhere. He’s a great guy to be around and also an an avid videographer, mounting a Ghostcam on the back of the truck capturing neat driving perspectives. You can see more of his adventures on his Instagram. We’ve had the pleasure of running with him on road rally events like Breakfast Club Rally. I even spotted Alex on HWY 101 S and at a local bar…you can tell how happy he is driving this truck. And yes, seeing a kei car in modern-day Bay Area traffic is quite the sight:

 

We asked Alex what’s next for the Sunny:

“In the future, I want to up grade the suspension and brakes (maybe I can get something ZCG to fit under 13s lol). Since I “somewhat” over modified my LS510, I decided to keep the sunny mostly stock. Soon, I am getting another A12 to use so I can rebuild the one under the hood to OEM.
I have always been a 510 guy, but I can’t help but like to drive the Sunny more.”

We appreciate your support Alex, keep Enjoying the Ride in your Datsuns! More photos in the gallery below

We met Bill in 2019 when he came to Z Car Garage on referral from our local Z Owners of Northern California (ZONC) club. He’s owned this pretty 1973 Datsun 240Z in Brown Metallic (code 114) for many years and had a list of small things that he always wanted to address. Before we cover the cosmetic and mechanical work we performed let’s hear how Bill got into Z cars…

Bill’s Z Story

 

“When I was about 10, my sister and her husband bought a 1979 280ZX. (They still have it but it currently doesn’t run.) I loved it. I always wanted a Jaguar E type and the Z has a similar shape. As soon as I could afford one, I got a used 1977 280Z and drove it to almost 400,000 miles when I finally wrecked it. I went a couple of months without a Z when a friend told me about a 240 he saw for sale. The owner was a teacher and so am I so of the 3 bidders I got it.”

 

“Then a few years later I went into administration and with the raise I thought it would be fun to have a new Z to go with the 240 so I ended up buying a 2008 350Z. I have had two Zs ever since. The 350 is definitely more capable and is very fun to drive, but I still think the 240 looks better. A really fun part of owning the 240 is taking it to car shows. I get a lot of people saying things like, “I owned a car just like this.” It seems to bring back a lot of memories for many people. Everybody loves the Z!”

Keeping Bill On The Road

 

When Bill came to Z Car Garage in 2019 we re-chromed his rear bumper, zinc plated various hardware, removed smog equipment and cleaned up the engine bay. A failing oil spray bar was replaced and we added ZCG exhaust, header and Z Therapy carb set.

Re-chromed rear bumper:

 
Zinc’d hardware:

 

New exhaust header and SU carb set from Therapy:

 

In 2022 we did more work to Bill’s awesome ’73. We replaced the radiator with a Koyo race unit, installed a Rebello street cam, adjustable T/C rods from T3 followed by alignment services in-house. We also replaced the speedometer seal rings and oil pan gasket. More detailed photos in the gallery below!

We took care of a few more items like weatherstripping and added a set of Holley retro headlights:

 

Enjoy The Ride

 

We have been taking care of Bill’s 240Z and enjoy working with him:

“ZCG does the highest quality work. They are very knowledgeable, honest and you can tell they really love Zs. It’s like they are working on their own car when they look at a customer’s car! It really feels like a new car. It needed a camshaft and some other parts and they did it perfectly. I love driving that car!”

We also take care of Bill’s 2008 Nissan 350Z convertible, to be featured on zcarblog.com soon!

 

What’s in store Bill’s 240Z? He’s always wanted a rally clock since seeing one at a car show 10+ years ago.  Also in the near future he wants to do a drum brakes to disc brakes conversion. Keep Enjoying the Ride Bill, thanks for your support and Long Live The Z!

John E came to Z Car Garage through a dealership connection at Dublin Infiniti. He purchased this Q50S Red Sport in 2019 with 46k miles on the odometer and it was time for bolt-on performance upgrades with dyno tuning.

 

We installed several parts from AMS Performance including their AMS Heat Exchanger, AMS Coolant expansion tank. Helping the VR30DDT engine breathe are AMS downpipes and a full Fast Intentions cat-back exhaust system. Photos of each are shown below.

 

The new AMS heat exchanger compared to the stock unit and installation:

The Fast Intentions cat-back exhaust replaces the restrictive OEM system:

 

Standard exhaust tips on the FI exhaust system, we love the quality, fitment and sound of these parts:

 

We also installed new Hotchkis sway bars front/rear. Stock vs new below:

 

Dyno Tuning

Straight from the factory, the VR30DDTT is an impressive motor rate at 400 hp and 350 ft-lbs tq stock. It is actually underrated as we have seen with dyno testing. With a few bolt-ons and tuning, even more power can be unlocked from the VR30. Rob tuned John’s Q50 using EcuTek, making 404hp/435tq at the wheels. A significant improvement over the 336hp/338tq baseline:

Enjoy The Boost John!

At Z Car Garage we specialize in performance modifications and tuning for the Nissan/Infiniti sports cars. Dyno tuning with UPREV or EcuTek software can maximize power gains from individual modifications like intake/exhaust upgrades. Josh M visited Z Car Garage for a dyno tuning session on his Nissan 350Z following an engine swap and we were happy to help him.  Let’s hear about his Z-car story…

Josh’s 350Z V.2

 

“I bought my car back in 2007 after graduating high school. I first heard about the shop shortly after I joined my350z.com back in 2008. After a few years and acquiring a full set of Motordyne bolt ons I finally called up the shop and met with Rob in 2013 to get it tuned. He wisely advised against it with how much oil I was consuming back then and suggested I come back with a fresh motor or rebuild (I’m thankful for his honesty and integrity).”

 

“Last year when that motor finally gave up around 200k it was time to swap all my mods to a new engine and call Rob for a dyno tuning session. My car made great power and surpassed my own expectations when it made 288whp and 274wtq on this swap from an ’04 G35. It’s always felt like a strong DE with a solid powerband and the dyno tune proved it. My main goal for the car is overall balance between drivability on the streets and performance on the track, and using our beautiful Santa Cruz mountain roads as testing grounds has helped me kind of find that happy spot.”

  

“As far as the exterior, a mix of KH3 super black and seibon carbon keeps it stealthy but also distinguished in the right light. I’m serious about the overall balance thing and reducing this 2 seater cars weight is a top priority, currently sitting at ~3100lbs and ideally want to be under 3k lbs.”

Dyno Tuning at Z Car Garage

 

A typical dyno session begins with a road test and full inspection before hitting the roller. We found a failed inlet hose and loose plenum bolts so we tightened everything up to ensure a successful dyno pass.

 

We dyno tuned the Z with UPREV and ARC license. Z Car Garage offers this ARC (Advanced Racing Controls) license add-on service to the existing UPREV Flash, allowing adjustable launch control, burnout mode, and flat-foot shifting for $150. This is for cars with manual transmission, VDC/cruise control. Call Rob for more details! Josh’s Z made 288hp/272tq to the wheels, a significant gain over baseline of 274hp/261tq:
