Josh’s Supercharged Nissan 350z

Filed under: 350z,Featured Cars and Projects,Performance
by Alvin G @ 6:47 pm on May 27, 2020

 

At Z Car Garage we live for anything Nissan/Datsun and that includes late model cars like the 350z. The Z33 has been part of our customer base since the beginning, spanning everything from NA and forced induction to full track-spec builds. Josh visited us last year to discuss supercharging his 2008 350z. He acquired it completely stock 3 years ago and slowly began the modification process.

 

Josh signed on for a Stillen supercharger kit (satin, CARB legal) and we installed it with our typical supporting mods like GTR plugs, and Concept Performance Z 25-row oil cooler  (Setrab, T-stat controlled).

 

The front end needed work to accomodate Josh’s front crash bar. We shifted items around like the water-air exchanger to retain functionality:

 

Josh also requested installation of parts he had purchased previously like Tomei cams/valve springs for the HR engine. These units worked really well with the blower as seen in the dyno below. A few cam install pictures:

 

The transmission was crunchy in 3rd and 5th gear so we installed a brand new OEM CD009 transmission:

 

Backing the VQ is a Z Speed Performance South Bend stage 2 clutch with internal slave delete (CMAK upgrade):

 

For piece of mind we replaced all engine gaskets and seals:

 

The differential bushings were replaced with Whiteline parts:

 

Before/after the Stillen Supercharger installation:

 

On the dyno the Z made 286hp/252tq baseline. Rob UPREV tuned with the Stillen supercharger making 427hp/311tq at the wheels:

 

Enjoy the dyno video:

 

Finally, we had our man William install Josh’s supplied carbon fiber hood, fenders and hood pins.

 

Josh was really happy with the results and he’s been texting us often:

“I brought in my base model 350z to Rob to get it Supercharged, cammed, and a transmission swap. I was pleased with Rob and the teams work, they knew what was needed for the build. The tune is excellent, I haven’t had any issues with engine codes after excessive driving.”

Enjoy The Boost Josh!

Daisy’s 1972 Datsun 240z

Filed under: 240z,370z,Featured Cars and Projects
by Alvin G @ 4:34 pm on May 22, 2020

 

We had the pleasure of working with Daisy to help get her 1972 Datsun 240z back on the road. Our Z Car Garage Big-Brakes and Z Car Garage CV Axles along with upgraded suspension parts transform this Z into a fantastic sports car.

 

Before we dive in to the upgrades let’s take a look at Daisy’s story:

“My Z history actually started with a 370Z–it was my first car, bought even before I knew how to drive a stick. When I was ready for my next automotive chapter, I tried to think of another beautiful, fun, sporty coupe that wasn’t going to cost 60k, and realized it was my car’s great-great-great-etc-grandmother–the 240Z. So I was on the lookout through Craigslist for almost a year, in search of an S30 that hadn’t had a ton of performance work done to it already, but was still in overall good shape…

… I migrated to eBay and found my car in Texas. I have a vivid memory of standing in a drizzly parking lot a 7AM on a Sunday, watching the car transport guy reverse the Z up a slippery metal ramp to get it off the truck. I chugged it around the parking lot to get a feel for everything, couldn’t get the seat close enough to the wheel and had a TERRIFYING drive back to San Francisco. But I was obviously, already in love…I spent a couple of years really doing the bare minimum to get the car roadworthy, and it was a real champ, flawlessly performing on one very hot and sweaty drive to and from SoCal, but it started to feel like I wasn’t using the car as much as I’d like because it simply wasn’t practical–the suspension was super soft, we were getting tons of cabin fumes, the brakes made my parents incredibly worried (ha!) “

 

Daisy was looking for a shop to take care of her 1972 Datsun 240z  and heard about ZCG from a few different sources–the Z Car FB group and from following Courtney Frisk (Cutchen) the automotive photographer, who’s also worked with us:

“I knew that it was time for some more significant work, so I got in touch with Rob. Ultimately, the goal was to make this a capable daily driver (though I only really use it on the weekends)–not super powerful, just safe(r), reliable, capable, reasonable to drive on contemporary streets–a joy to drive.” 

Daisy brought the Z in late last year and we performed a full inspection.


The inspection revealed many items to be addressed from brakes, suspension to carburation which was really off. Initially we spent a few hours getting it driveable while we put together a plan to add some ZCG touches to her S30.

ZCG Big-Brakes and CV Axles

We handed Daisy the keys to “Mrs. Butters”, our 1971 Series 1 240z shop demo car and she 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 customers 🙂 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 Daisy’s stock brakes and installed our ZCG Big-Brake kit. The chassis was treated to a full suspension rebuild with new parts, bushings and a full coil-over (Koni) suspension from Techno Toy Tuning. T3 finishes the suspension in our signature color and we really appreciate Gabriel and his staff. They make some of the best suspension parts out there for Z cars.

 

ZCG Big-brakes and T3 coil-overs replacing stock setup up front:

    
 

More pictures of the front suspension refresh with T3 T/C rods and lower control arms, ST sway bars, rack bushings and f/r wheel bearings. We also replaced the steering coupler:

 

At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality IS retained!

 

Rear T3 lower control arms, and more refreshed suspension parts and rear Big-Brakes also shown:

 
 

We replaced the brake booster and master cylinder with NOS parts: our Big-Brakes require nothing more than the factory hydraulics!

 

Daisy really wanted the look and feel of Mrs. Butters Z without being too low or riding rough. Mission accomplished: the Z looks fabulous from any angle:

 

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 90 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 

Daisy has CV Axle set #329. Stock half shafts (L) and ZCG units:

 

More pictures of the ZCG axles installed, also visible are the T3 control arms and re-sealed diff:

 

Engine

With suspension sorted, Daisy signed on for a major service tune since we had trouble getting it to run correctly. We replaced the plugs, plug wire set, cap/rotor, fuel filter, replaced VC gasket, installed a MSD blaster2 (black) coil and performed a valve adjustment and oil/filter change.

 
 

We replaced intake and exhaust manifold gaskets with factory Nissan parts and few ZCG tricks including a certain exhaust nut and exhaust stud.The exhaust manifold was replaced with an MSA 6-1 coated header and our ZCG exhaust system with stainless resonator and slash-cut tip

 

Details


A few more items were sorted:  the differential was resealed with new front/side seals:

 

The Z was cut/buffed with a detail. Finally, the tension springs for hood were replaced and the Z now ready for Daisy to pick up.

 

Driving is Believing

When Daisy and her fiance picked up car, they were blown away:

“I’ve only had the Z back for a few days, but it’s incredible! I knew Rob’s tuning was great from the first “check-up” he did on the car, but getting the car back with the Big Brakes, the new suspension, and axle kit–it’s honestly like a new car. My fiance and I were finding ourselves bracing for the bottoming-out-scrape we’ve become used to from the old suspension, and the Z now just sails over them! The exhaust note is beautiful, I can stand behind the car without choking on fumes, and it’s what I really hoped it would be–both practical, and a joy.”

 

The Z was a big part of their engagement photographs in the hills above Bolinas (photographer, Helena Martin)

 

We enjoyed working with Daisy and she’ll be back for either triple-Mikuni’s or rebuilt SU’s and some dyno tuning:

“Working with Rob and ZCG in general is what working with a shop should feel like. When I first got in touch with Rob, we had a detailed “intake” conversation about what I was looking to accomplish with my Z. This was an early, awesome indication that ZCG really values listening to what customers want, not just churning out identical builds or upgrades, or pushing one kind of perspective. While I’d heard that lead times working with ZCG could be long, Rob was always available to chat and check in, answer a question about the work, or listen when I found a new nit to pick about the car. Rob is also just an excellent guy–It’s clear to anyone who’s met him that he’s deeply passionate about this work, and it’s infectious, even for folks who have already caught the Z bug.

Thank you for entrusting us with your S30, Daisy. We are so fortunate to work with owners that appreciate the Z and believe in our ability to make them better! LONG LIVE THE Z!

Z Car Garage wishes you a Happy 5/10 Day and Happy Mother’s Day! We enjoyed driving our 1971 Datsun 510s on a beautiful day in San Jose. Turbo6, our 80’s revival, is back on the road and running great with its turbocharged 6-cylinder L-series. Look for a full report soon:

 

Rob, Meghan and Tank were in the SR20DET-powered 510:

 

A few photo-ops in Downtown San Jose:

 

We got the Bay Area Datsun Dealers race 510 out too!

 

Enjoy The Boost in this video of the 510s in action. We hope you can Do It In A Datsun today too!





 

Ever wonder about the history behind this famous IMSA-GTU Championship-winning 240z? Check out www.my240z.com. Our friend Glenn Chiou created this new website to document the racing provenance for current owner David Martin, who we have shared racing at Laguna Seca with at several events:

 

Glenn’s impressive knowledge of historic Nissan/Datsun racing is bolstered by hundreds of scanned photos, some never seen before along with stories from ex-drivers Brad Friselle, Jack Scoville and John Morton. We are even given new insight on the R&D effort that went into the Friselle car making it by far, “the best race engineered 240z in its period”.

 

 

So if you want to know “what’s it all mean?” check out www.my240z.com!

 

Enjoy a few videos we’ve captured over the years racing with David Martin piloting the Transcendental Racing 240z:




Efrain’s Q60S

Filed under: 370z,Featured Cars and Projects,Performance,Q50
by Alvin G @ 4:22 pm on May 5, 2020

 

At Z Car Garage we have been maintaining and modifying late model Nissan/Infiniti sports cars since 2004. From Z cars (Z32, 350z, 370z) and R35 GT-Rs to G35, G37, Q50/Q60 cars we look forward to working on your vehicle. Efrain S visited us from Sacramento with his 2019 Infiniti Q60S Silver Sport for basic performance upgrades from AMS Performance including their AMS Heat Exchanger and AMS Air intakes and a Z1 Motorsports Blow-off Valve kit:

 

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

Z1 BOV Kit with red couplers:

  
 

Dyno Tuning

 

Straight from the factory, the VR30DDTT is an impressive motor. The Hi-Output version is rated at 400 hp and 350 ft-lbs tq, 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 dyno tuned the Q using EcuTek. Baseline power was 333hp/314tq at the wheels. With the AMS parts and tuning final numbers were 412hp/452tq, gains of +79hp/138tq:

 

The VR30-series responds so well to bolt-ons and gets us excited. It’s almost like Nissan has comeback full-circle as the VR reminds us of modifying Z32TT’s in the 90’s:  big gains with just few upgrades. The Q-series cars are really well-suited to the upgrades too with a very comfortable ride and massive hp/tq when you want it.

Here is the Q on the dyno:

 

Efrain was very pleased with the power gains:

 “Honestly man my experience with Rob from start to finish was amazing. I could tell he loves his job, loves what he does and energy was on 100%, 7 days a week. Once I got the results back from the tune I was blown away I thought I was maybe going to see about 400 horsepower to the wheels at the most and he got it over to 412 with 450 torque, I couldn’t believe it. My bolt-ons are flawless, could not be anymore happy with the work from you guys and the whole experience I love the car thank you guys.”

Enjoy The Boost Efrain!
