Z Car Garage has been supporting the Nissan/Infiniti Z and G-series sports cars since 2004. At just about any time during the day at our shop you can spot a 350Z, 370Z or G37 undergoing routine maintenance or performance upgrades. Many of our late-model Z car clients are referrals and we are happy to oblige when scheduling allows. We met Frank M in 2020 when he had us perform clutch work on his 370Z. The install went super smooth, and Frank and Rob began their relationship.

“I first heard about The Z car garage through another Z car enthusiast, he had nothing but great things to say about the service he had received working with the crew there. I reached out the Rob to have my 370Z’s clutch replaced with the Z-Speed CMAK clutch kit. That was the first job you all did for me.”

A common issue on the 370Z is the internal slave failing due to heat. Thankfully Z Speed Performance makes a kit to convert the internal slave to external (CMAK Upgrade). We installed their Stage 1 Clutch kit on Frank’s Z:

   

On his next visit to ZCG, Frank had us perform an alignment after suspension work including Eibach Pro-kit lowering springs (KW-V3 coil-overs next) and Hotchkis front and rear sway bars and SPC rear adjustable camber arms. We also replaced the rear diff bushings with new Whiteline parts.

 

Frank is a handy guy and he’s done much of the work on his Z himself. For something that is beyond the scope of a simple weekend project he brings it to ZCG. In summer 2022, with 77k miles Frank installed an oil pressure gauge (VLS) and didn’t like the levels it was reading. There is a very common issue on the VQ37HR where  oil gallery gaskets fail, resulting in low-oil pressure to front of the engine.

 

CPZ makes updated gallery gasket with really nice hardware. At the same time to help with oil cooling we installed the CPZ 25-row oil cooler with a thermostatically-controlled Setrab unit:

 

Wheels Make the Car

Mark has great taste in wheels, choosing a set of Work Racing CR2Pwith Michelin Pilot Sport 4s tires 265/35 and 305/30 rears:

 

We spent time with the 2023 Nissan Z back in June and Frank was kind enough to lend us his WORK wheels to test fit on the RZ34:

 

Frank purchased his 370Z bone stock, being the second owner and has added the following mods:

Drive train 

Fast Intentions stainless steel CBE exhaust

Stop Tech front and rear vented drilled and slotted zinc coated rotors

Stop Tech carbon ceramic pads front and rear

Stillen CARB legal cold air intakes

VLS oil pressure gauge

Aesthetics

Custom retrofitted headlights by me honey comb projector lens. Blue demon eye. Black and gunmetal paint job plus new Morimoto clear lenses.

Evo-R carbon fang cover,carbon type three front lip, carbon upper bumper cover, pearl white base carbon top high wing and CF door handles

Fujimura rear lower diffuser

Enjoying The Ride

You can catch Frank carving up the Bay Area backroads like HWY 9 runs up to Skyline and Alice’s:

 

Frank is stoked with his Z car:

“The performance gains from the work Z Car Garage performed was great. The clutch feel is much improved and does not slip it also seems to shift smoother. The oil pressure is up 15 pounds at idle from the oil gallery gaskets and the car runs much cooler after the oil cooler install. I think the cooler temps help the car not heat soak on hot days while pushing it on back roads. The best thing about the Z car Garage is when I leave my car there for service, I never worry about it being there. I know the car is taken care of as if Rob owned it himself. I have nothing but good thing to say about you all. I do a lot of work on the car myself but Z Car Garage is the only shop I will use if I need the help.”

 

Thanks for your support Frank it was pleasure working with you and seeing enjoy your Z. See more photos in the gallery below, and contact us to schedule an appointment for dyno tuning, maintenance or upgrades on your 370Z or Infiniti sports car!

Hello and good morning Dear Zcarblog readers! We have many customer car and event reports to bring you this week, so let’s get to it.

If you are a fan of Japanese classic cars there’s a good chance that you have visited Japanese Nostalgic Car. JNC’s senior minicar correspondent and all-around J-Tin guru is Ricky Silverio and he is also a Z-car owner! Here is his pristine, 10k-mile 2003 350z Track model that we will be performing services on soon:

   

Enough about Z cars let’s talk about the other steed in his stable…Ricky recently visited Z Car Garage with his 2017 Mustang GT:

“Although the public knows the shop specializes in Nissans, I am aware of the broad range in specialty that ZCG possesses. What really stands out in the cars no one knows about is the DSE equipped Camaro that was done a few years ago as well as the myriad race and special projects. That’s what makes me know that ZCG is a misnomer as everything can be accommodated at the shop.”

 

 

The Premium-package equipped Mustang came to us with only 226 miles on the odometer and we happily obliged Ricky’s request to begin modifying it. Ride height and handling were addressed with an Eibach Pro-kit:

 

We discussed Ricky’s driving preferences and intentions (neutral, good turn in, street-use) when choosing alignment settings following the new spring installation. He was stoked:

“Although I chose mild springs I was surprised that brake dive was eliminated, turn in was very crisp and the car became more tossable. Firmness was slightly higher but the difference is huge which surprised me. But I must add the alignment specs really made the difference and ZCG delivered as always!”

 

What’s next for the Mustang? Since Ricky is comfortable with ZCG, on his next visit we will perform a baseline dyno and intake/exhaust mods. Ricky will have joined the ranks of a rather peculiar correlation between Z car owners and Mustangs demonstrated by our customers Jeff V, Kevin B and Scott L. Z/Mustang associations aside, Ricky is a car enthusiast with a love that started with Japanese cars and encompassed all:

“I love all cars and although I have been versed in Japanese cars since the day I was born, I dig everything! I used to have old minis and European Ford escorts and my uncle was into restoring old 60s American cars (Mustangs too) so that’s where my love for muscle cars were born.”

Here is Ricky’s ridiculously clean, 30k-mile NA Miata sitting on Enkei RPF1s and tasteful interior upgrades:

  

Ricky and I had some lively discussions about his latest Ford purchase and the new S550 Mustang’s design.

“The S550 Mustang chassis when it came out gave me the best of both worlds. Iconic car and platform but now with IRS and finally true world car engineering and refined elegant and beautiful design. The Americanness of the car can be found in its size (I’m still getting used to its length and width) as well as its V8, typical ford panel fit, rattles and various hard plastic surfaces. Other than that the experience is vastly different as the car really is a now a “normal” globally accepted and designed car. From its IRS, Getrag 6 speed, it feels more European / Japanese in dynamics.”

 

We both agreed that the new Mustang is the spiritual successor of the S15 Silvia, an “S16” if you will or the car Nissan should have built!  Ricky then took it up a notch drawing a connection between an old school Toyota and the Ford:

“Totally agree Alvin that by subliminal design (even chassis code with an S and 5) that with the Ecoboost the Mustang truly channels the S15 Silvia! With the V8 it even channels the true first release of the original Celica Liftback (twin cam 2 liter) which the US never got, especially in white”:

 

“That’s what does it for me. It channels those Japanese cars but also caters to the heritage of the Mustang which is what inspired the Japanese cars in the first place! Imagine Japanese cars inspired by the original Mustang, and now the newest Mustang channeling the qualities and design of the cars that were inspired by it. Mind blown.”

 

Even though we are a Nissan specialty shop we never leave our customers hanging with their other rides. We love the new S550 and Ford is one of those companies that gets it. More to come as we work on Ricky’s Z33 and GT!

 

 

Taka Y visited us in 2012 for some maintenance on his pretty 1972 S30. Originally the classic orange in color, we love this metallic red shade as it shifts from burgundy in the shade to a brilliant ruby in direct light.

 

In addition to sorting out the SU carbs we added Pertronix electronic ignition, did minor suspension work and cleaned up the fuel tank and all associated hoses:

 

After a few years of enjoying the Z Taka came back to ZCG for more suspension upgrades and clean-up work. Starting with the suspension we chose new rear lower control arms from TechnoToyTuning (T3), Eibach springs , KONI classic shocks and f/r sway bars:

 

Here are the original rear control arms and new T3 adjustable parts:

 

Both lower control arms installed:

 

The rear end also got treated to new mustache bar bushings:

 

Up front the lower control arms and T/C rods were cleaned, primed and rust-proofed:

 

We installed a new clutch master cylinder and clutch slave followed by full hydraulic system bleed with Stoptech 600 fluid. New hoses shown below (L): On the right, Taka’s L-series oil pan gasket was seeping oil so we replaced it with a new competition piece:

 

Here is the pan coming off and new comp. gasket applied. A new oil pressure sending unit was also installed:

 

We replaced the old, worn motor mounts with new pieces:

 

New vs old motor mount isolators:

 

With the chassis, engine and hydraulics sorted we improved aesthetics by changing the wheels. We really do love the Panasport wheel and over the years they improved their casting/design. The latest offering is stronger and lighter with stunning finishes. Below (L) it’s easy to see the difference in tire dimensions…

 

Taka’s 80’s era 280zx 14″ wheels were mounted on gargantuan 235/60/14 tires. The new Panasports are sized 16×7 (11mm offset) and shod with 225/50/16 Bridgestone RE760Sport tires.  Taka’s Z now has a sportier, updated look with performance to match thanks to this wheel/tire combo.

Enjoy The Ride, Taka. We love your 240z!

Kevin R has been a Z Car Garage customer for over 10 years. His last visit to the shop in 2013 included an entire dash overhaul, minor suspension work and carb tuning:

With close to 400,000 miles on the chassis of his 1973 S30 years of dirt and grime had taken its toll on the chassis. We decided it was time to refresh and upgrade the suspension front/rear with Tokico 5-way adj. shocks, Eibach springs and several parts from Techno Toy Tuning (T3):

 

The ball joints had seen better days! Fresh boots with grease and a thorough cleaning does wonders!

 

More front end services including new T/C rods and roll-center adjusters from T3.

 

New front control arm and steering rack bushings:

 

New Tokico shocks and Eibach springs about to go in:

 

At the rear we degreased the diff housing and installed new moustache bushings:

 

More grime and new T3 rear control arms:

 

 

Finally we mounted new 215/45/16 tires on the old-school O.Z. Monte Carlo wheels followed by a full alignment. Kevin’s Z is now ready to tackle thousands more miles of twisty roads!

 

Marc H found Z Car Garage online and wanted to see what we were all about. After visiting the shop he dropped off his ultra-clean, low mileage 2008 350z for power and suspension goodies:

 

We love the HR engine found in the latest Z33s because they respond extremely well to simple bolt-ons and UPREV tuning. We started with a with Bassani cat-back exhaust followed by JWT dual POP charger intakes :

 

On the dyno, Marc’s 350z baselined at 271hp/245tq to the wheels.  The Bassani exhaust netted a peak gain of 7hp and significant midrange gains in torque:

The JWT intakes added an additional 4hp:

 

This graph illustrates the benefit of UPREV tuning when adding bolt-ons. More power everywhere, all the way up to 7500rpm for peak gains of 19hp/8tq for a total of 290hp/253tq to the wheels:

 

Marc wanted to improve handling and braking so we installed Eibach springs, Hotchkis sway bars, and Whiteline T/C rod bushings followed by a full alignment. Factory Brembo brakes were upgraded with Stoptech Sport Kits all around:

 

Sway bars:

 

Marc was very pleased with the results and has been enjoying his Z.  He told us he would be coming back to ZCG and we will happily oblige!
