TUNING: Tyler’s Porsche 914

Filed under: Featured Cars and Projects,Performance
by Alvin G @ 9:14 pm on December 3, 2023

 

Tyler has been in Rob’s life since he started working as a head engineer at Stoptech. He is behind Research and Development of our Z Car Garage Big-Brakes, and we couldn’t have done it without his drive and passion. Our collaboration with Tyler always results in excellence, so when he mentioned bringing his Porsche 914 up from SoCal we happily obliged to work on it.

 

TYLER: “Rob Fuller/ZCG and I have known each other for a while now through my Engineering work at StopTech. We developed the Z Car Garage Big-Brakes for small wheels together. During the development of the BBK, Rob Fuller the man himself would constantly call me and leave hilarious singing voicemails, mostly him belting out hair-metal versus then saying “CALL ME BACK!”. We really hit it off during this time and grew to have a deep respect for one another.”

 

“I think we were able to really nail the final product after lots of tweaking and testing. ZCG was stoked with the BBK and I was stoked to work with such an amazing shop and crew. This project has always been a highlight for me. So when Rob asked me about my 914 and heard about my troubles with it he instantly offered to help out. This was definitely an offer I couldn’t refuse, so I brought my 914 to the shop.”

 

History

 

Before we go into the work ZCG performed let’s hear from Tyler about his 914…

TYLER: My first car was a 1973 914 2.0 my Dad, brothers, and I bought for $1200 ~25 years ago. We fixed it up and started to race it together, we still have it and plan to get back to racing it one day soon. Ever since then I wanted another 914 for myself. I just like the fact that 914s are mid engined, air cooled, and has a horizontally opposed engine, all of the coolest Racing Porsches are in this configuration. Also the 914 is three more than a 911, so there you go. When I saw the 914 on a Tucson AZ Craigslist post in 2015 I knew I had to snag it. The car was an old PCA/POC race car that raced in the 70s and 80s in AZ. I knew the car was a diamond in the rough even though it wasn’t running and had many problems to address.”

 

“I ended up buying it from someone in Tucson AZ for $3000 and towed it back home. Ever since then I have been fixing it up and getting it running well enough to enjoy classic rallies and some track days. I have been sort of converting it back into more of a streetable car but still keeping it raw and sort of rough that still gives you a feeling of a race car. My favorite thing to do is go for a drive down PCH with my wife and my dog squeezed in between us and stop at the beach for a walk and swim or rip the snot out of it on the track.”

Chassis and engine details on the 914 below:

Engine & Transmission

The Z Car Garage Touch

 

ROB:Tyler had his car dyno-tuned previously but it wasn’t running well. We like to make cars better, so we performed suspension work, adjusted the valves, sorted out his carb linkage, ignition system and made it awesome. Upon arrival it had a really bad front windshield install, so we replaced it and the stainless trim. New valve cover gaskets, cap and rotor, re-did the throttle-linkage return springs, serviced the air filter. Basically went through the Porsche like we do with our Z-car clients so he could enjoy driving it again.”

 

Dyno Tuning

With carb work, timing and linkage adjustments the 914 made 110hp/115tq at the wheels, gains of 18hp/15tq from baseline. Tyler was really happy with the results:

 

TYLER: Rob gave my car some serious balls…I don’t have the official numbers of the final dyno run but the car feels like it’s been hitting the gym HARD. Engine runs super smooth, sounds like a completely different beast, starts without issue, is really responsive, runs a lot cooler, and has an overall boost in power! It has increased the enjoyment factor 100%.”

Enjoy this video of the dyno run and Tyler driving home from the shop down to SoCal:

After checking the suspension we mounted fresh Toyo RA1 tires followed by a full alignment in-house. Tyler was ready for the road trip home.

 

If it ain’t the Z-car, please let it be the P-Car!

 

Tyler shared a few photos from his roadtrip down to SoCal, catch his adventures on Instagram. Thank you Tyler for letting us work on your 914 and continued support for our Z Car Garage Big-Brakes. Stoptech or Don’t Stop At All!

TYLER: “ZCG is one of the top shops I ever had the pleasure of working with. As a customer, the experience was equally great. The team is really driven, they have expertise to really handle tricky stuff and strive for perfection with everything they do. I knew my 914 was in the best of hands even though ZCG specializes in Z-cars, their talent easily translated into P-cars.”

TUNING: Alex’s Datsun Sunny Truck

Filed under: Featured Cars and Projects,Performance
by Alvin G @ 12:00 pm on November 29, 2023

 

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:

 
 

Enjoy this video of the Sunny on the dyno at ZCG:

 

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

Bill’s 1973 Datsun 240Z

Filed under: 240z,350z,Maintenance,Performance
by Alvin G @ 2:40 pm on November 21, 2023

 

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!
New camshaft installation:

 
 

Adjustable T/C rod before/after:

Dyno Tuning

On the dyno the L24 made 137hp/138tq to the wheels:

Details

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’s Infiniti Q50S Red Sport

Filed under: Performance,Q50,Q60
by Alvin G @ 8:50 pm on November 6, 2023

 

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 ExchangerAMS 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:


AMS expansion tank installed replacing two plastic OEM units:

 

AMS downpipes:

 

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 dyno video below:

 

Enjoy The Boost John!
