Love Thy Monster: Paul’s 1991 Nissan 300ZX Twin Turbo

Filed under: Maintenance,Performance,z32
by Alvin G @ 7:09 pm on June 15, 2020

 

Paul Ferrari has been in our life since 2002. Prior to launching Z Car Garage, as a young man Rob worked on Paul’s 1991 Nissan 300zx Twin Turbo. Paul is super enthusiastic and he is similar to Rob—there’s never enough power.

 

Our journey with Paul’s Z32TT spans almost two decades. It made plenty of power back in an era where it was uncommon; nowadays 500hp is easy to achieve with current performance parts.  From a NA-TT setup to full disassembly and restoration with lessons and tricks learned along the way…Paul has been a devoted friend and customer. Folks like Paul contribute to the success of Z Car Garage and we love when customers see ZCG as “their own” garage. Let’s take a look at how Paul found his 300…

Z32 Destiny

 

Paul recalls how we acquired the Z in December 2002, after passing on a MkIV Supra:

“When I first saw the Z in the seller’s driveway…It was one of those moments that is burned into my memory! I was amazed! The look! The stance! Even the license plate, “500HP”!  It had all the typical import performance parts of the era:  JWT Sport 500 turbos and test pipes, Stillen intercoolers, Stillen “dual pop chargers”, RCE 550 injectors, JWT ECU, HKS EVC, Apex’I Super AVC-R, Greddy Turbo timer, and OZ 17 inch-5 spokes. There was no doubt in my mind; this was going to be my car. It was so sexy, sleek and fast!” 

 

He reached out to Rob for a commensurate pre-purchase inspection and eventually purchased the Z:

“It only took a few phone calls to dealerships and other import shops to zero in on a guy named Rob Fuller at Scott Performance.  I think Rob’s name was mentioned in 3 out of 4 calls. It was well known, even before Z Car Garage that if you needed someone to look at your performance Nissan that Rob was the guy you wanted looking at it.” 

In 2004, Rob started his own performance shop, Z Car Garage. Paul Ferrari was one of many customers that followed and he certainly had the itch for more power. This led to the first high performance engine build, circa 2004:

 
 

We had Rebello build the VG30 with H-beam Rods, forged pistons, rebuilt the bottom end and heads, ordered JWT Sport 700 ball bearing turbos along with a set of big JWT cams, bigger intercoolers, bigger injectors and a laundry list of miscellaneous items.  It was good for 570hp/483tq at the wheels. Paul enjoyed it but shortly after he had run it on high boost without race fuel causing engine failure…

“Proof of my escapade that day still hangs on the wall between the shop and the office at Z Car Garage in the form of a stout, but severely bent H beam Rod attached to a piston with broken ring lands.  Correct me if I’m wrong, but I think mine was the first installment ever on the Z Car Garage wall of shame. ” 

The NATT is Born

Rob offered Paul a loaner motor out of a naturally aspirated Z32. Through some interesting twists and turns in Paul’s life, he was even a ZCG employee at the time. The crew discussed hanging his turbos on it, and to install the turbo cams since they were still at the shop. We all agreed, and it would be affectionately called the NATT    (Naturally Aspirated Twin Turbo). It was surprisingly good, and still a fond memory for many of us.

 

Paul’s life changed and he moved out of the Bay Area. With his life in transition eventually the NATT was pulled, and the Z sat in storage from 2008 to 2012. In this period we had the engine refreshed by Rebello, and had the car sent off to Williams Autobody for paint and installation of a new Veilside EC-01 front bumper and Karuma rear spoiler.

“During the time my car was mothballed, innovations at Z Car Garage never ceased. And since my car was just sitting, Rob and I were able to add almost everything to my build sheet.  Some of these innovations disappeared as fast as they came, some stayed. CZP 2.5 inch intercooler piping, larger throttle bodies, Bell intercoolers, a 4.08:1 Leaders gear set and KAAZ Limited slip diff; smaller exhaust housings and modified impellers on the turbos, Mike Smith high flow cast exhaust manifolds, a Selin dual MAF, ASHspec dual inlet piping, and several items from Specialty Z. ” 

Final Form

 

In 2012, Rob had started using Haltech ECU’s to unlock the power of his builds and was getting amazing performance results across the board.  He’d also been experimenting with Turbo exhaust housings, and modified impellers, cam profiles, and cam timing, along with a whole host of innovations for S30’s to Z34’s. We called up Paul and asked him to drive Rob’s newly-built Z32TT ( with tuning thanks to Seb of SpecialtyZ)

Paul recalls the experience

“So, he calls me one day and says, ‘Man you need to come down and drive my Z.  You’ve got to experience the gains we’re getting with these Haltech’s.’  That car broke loose at 70 plus and went beyond 100 faster than anything I’d ever driven, and far faster than any Ferrari I’d ever ridden in, and for me, from that moment on, that’s all I could talk about and think about. During the era that my car was mothballed I had sold a house, changed careers, retired, moved to a different city, and had taken up off roading and traveling in a big way, so by the time I was able to house my Z, it was ready to be finished up and delivered.  And along with all the innovations that had taken place I was now going to have My Monster.”

Drivetrain

 

We removed the NATT from his Z and began the epic build, applying all the tricks we learned starting starting with a fully built Rebello 3L. The list includes: Sport 500 cams, HD springs all new lifters, and lots of headwork…

 

…3″ downpipes, 3″ mid pipes, SZ 2.5″ cat-back exhaust, BB700 turbos, BDE engine mounts, Ashspec inlet piping, Tomei exhaust cam gears, BDE cam gears, Mike Smith manifolds with EGR, SZ big IC piping and massive intercoolers, brand new transmission from Nissan, SZ high-five clutch/flywheel and a Haltech plugin Platinum Pro ECU with boost solenoids and map-based tuning:

 

More build pics in the gallery below! Here is the fresh, hot-rodded VG30DETT installed:

 

Rob dyno tuned using Haltech,  a Greddy boost controller and 100 octane yielding 630hp/539tq at the wheels:

Chassis

 

In addition to the full engine build, the entire car was restored from interior to exterior. The chassis was treated to Stoptech ST40 front and ST22 rear calipers, Volk SF Winning 18″ wheels with 245/275 Bridgestone RE-71R tires, new driveshaft assembly, Leader gears(4.08) with Quiafe LSD, Tein coil-overs with EDFC Active Pro controller, SPL tension rods and titanium HICAS eliminator and a full wiring harness.

 

The exterior restoration included all new mouldings, new front glass, all new cowl panel, and every weatherstrip piece that is available from Nissan. The interior is just as pristine as the exterior:

 

Paul was pleased with the Z, as delivered in 2017:

“When I took delivery, Rob wouldn’t tell me the horsepower I was making till well after I had had several months to drive the car.  He eventually told me 630 HP, and 540Lb/Ft TQ on a relatively conservative tune at near Sea Level in San Jose.  It’s strictly a VP110 car now.  Here at home in Reno at 4500 feet above Sea level the tires easily break loose on the freeway going 70, at this elevation it is truly amazing!”

 

 

Enjoying The Ride

 

Paul is very serious about motorsports and he is into LS-powered sand rails and Haybusa-powered buggies etc. so he has a 55 gallon of 110 race fuel at his house. His Z is tuned for 110 octane and he regularly tracks the car at Thunderhill Raceway. We love to see him Enjoying The Ride! Track photos by Gorilla Tornado Photography

 

I track the car on club days, and I run it around the mountain roads of Tahoe and Virginia City, and take it to Cars and Coffee events.   I’ve gotten it up to 160mph, and maybe 170mph, and at the time of this writing the car is 29 years old, so I don’t think that’s too shabby!  It doesn’t need to go any faster, and neither do I.  It sits beautifully in the garage on a Battery Tender, along side a fuel jug full of VP110, waiting for its next rip.  It gets washed even when it doesn’t need it just for good measure.  It still rips and it still makes my heart race like nothing else. ” 

 

 

Enjoy this short video of the z in action:

 

“I found a Z Car that would not only invigorate my life but would lead me to the doorstep of such a long quest as a customer, friend, and supporter of Z Car Garage! I am honored and privileged to have been a part of the history of Z Car Garage.  I have a deep respect for Rob, the guys that started with Rob, and the guys who have cycled through in the shop, and I am privileged to have met so many great guys and gals that are passionate about performance Nissans.”

 

Thank you Paul Ferrari for being a part of the Z Car Garage family. It has been, and continues to be a rewarding journey working with you. LONG LIVE THE (twin turbo) Z!

Jay’s 1990 Nissan 300zx Twin Turbo

Filed under: Featured Cars and Projects,Performance,z32
by Alvin G @ 8:20 pm on January 24, 2020

 

Jay H has been our customer since the beginning. He has a Datsun 240z, Mazda (FD) RX-7 and this 1990 Aztec Red 300ZX Twin Turbo that he’s owned for many years.  Living in a rural, wooded area the Z’s wiring got chewed on by rodents. We fixed the wiring and got the car running again but more issues surfaced. Jay loves this Z so much and it had 122k miles so he decided it was time give it some serious attention.

 

Z Car Garage was happy to oblige as we think the Z32 is one of the best Japanese sports car of the 90’s.

Engine Bay and Drivetrain

 

The engine bay was in need of major cleaning and restoration. First, we performed a compression/leakdown test and the Z passed. With the engine out now we could focus on cleanup:

 

We installed a new engine room wiring harness. Every coolant hose, bypass hose, vacuum hose was replaced. A new underhood insulator with clips replaced the torn oem piece.

 

All p/s hoses were replaced and we modified the p/s steering pump to reduce clutter and eliminate the HICAS completely:


 

The engine was treated to full reseal and timing belt services, more pictures of the engine build in the gallery!

 

With a clean bill of health we installed several performance upgrades including JWT sport 500 turbos, BDE billet half moons/motor mounts, Ashpsec inlet piping, Selin dual-MAF with HR  low-profiles filters/two Z32 MAFs and Nismo 740cc injectors:

 

No turbo upgrade is complete without the Mike Smith turbo manifolds with EGR ( to pass emissions). Unfortunately we will install the last set of these on Felix C’s 300, and that’s it!

 

BDE motor mounts:

 

Nismo 740cc injectors:

 

Ashspec inlet piping:

 
 

Selin dual-MAF with HR low-profile filters:

 

Before the engine went back in we installed a new JWT HD clutch and aluminum flywheel:

 

The drivetrain was re-installed with numerous items like a new fan and engine cover:

 
 

Exhaust upgrades included a full SpecialtyZ 3″ exhaust with 3″midpipes:

 

Finally, a GReddy Profec boost controller was installed in the super tidy interior:

 

Rob dyno tuned the Z, making 384hp/348tq to the wheels:

 

Exterior

 

With the engine bay and drivetrain sorted we turned to the body and and exterior trim. Jay wanted to do a full repaint on the car so we had it had it towed engine-out to our man William. Some before shots showing the faded paint and cracked/peeling tail light panel:

 

At William’s the body got some choice parts to make it look like 1990 again: Wings West Pre-’94 rear wing, JDM front fascia (with shaved license plate mount) and Jspec tail lights. With the freshly painted Z back at the shop we tackled re-assembly of new cowl panels, mouldings and various trim. All of these parts really make this Z pop:

 

Extensive moulding/trim replacement: T-top trim before/after shown below

 

Door and window trim:

  
 

Jspec rear and front looking sharp!

 

Icing on the cake are Jay’s super cool set of old WORK Equip 05 wheels.  We re-finished and polished/painted them running Bridgestone S-04 tires.

 

Wheels make the car and this Z looks incredible standing still and on the road:

Suspension

The chassis received a few upgrades including Stillen sways and SPL titanium HICAS delete We also replaced ABS module the clutch and brake master cylinders

 

One Z Car…Coming Up!

 

Jay didn’t have a car for the duration of the revival and he was on foot running errands near his home.  We handled all of the DMV fees foe him and Rob and Alvin delivered the Z to Jay at his residence.

 

It was a great experience to pull up in the 510 and Z to present it to Jay, he was all smiles:

 
 

Thank you Jay for bringing your 300zx to Z Car Garage. We admire your love for the Z and passion to keep it on the road in top form! Z32s ROCK! Enjoy the extensive photo gallery below:

LONG LIVE THE Z!

Getting Back to the Basics

Filed under: Performance
by Forbes @ 9:54 pm on October 27, 2009

Not everything we do at Z Car Garage is a ground-up restoration or a hardcore twin turbo build.  In fact most of our customers come to us just looking for just a little more of what they already love about their cars.  In this case we will be taking a daily-driven G35 and adding a little bit of sport to it’s luxury coupe status.  Nothing too crazy, just improving on an already astounding car.

One of the many great things about the VQ35 engine series is it distinct exhaust note.  I can be in my house, out of sight of the road, and be 100% certain when one goes by, be it in a G35, 350z, FX35… whatever.  After searching long and hard for an aftermarket cat-back exhaust system to compliment the factory sound without too much rasp we came to Bassani.  We have been using the Bassani systems for quite some time now and have been more than happy.  They improve upon the already sporty exhaust note and they seem to be one of the top performing kits on the market today.  This was a must for this car.

Not wanting to leave the intake side of the engine jealous, we opted for a simple but effective Jim Wolf Technologies (JWT) POP charger setup.  This air filter is much more free flowing than the factory panel filter set-up and it allows for your ears to enjoy just enough of that beautiful intake sounds that we all love.  JWT is a great operation and their parts are top notch which makes this part another must.

Now on to the handling side of the equation.  A simple and proven set of Eibach springs will do the trick here by giving us the stance we want and a higher spring rate for the cornering that we deserve.  The other part of the equation here is the set of red Hotchkis swaybars which are meant to keep body roll in check during any high G events.  Simplicity at is finest.

From the chart below you can see that there are certainly a few more horsepower in the mix after the intake and exhaust modifications, but with this being an automatic transmission car the gains tend to be a bit masked by the slush box.  Another upgraded daily driver in the hands of a satisfied customer, job well done.  Until next time…

There is a full gallery of photos after the “read more” below.  They are in order from when the car came in to the shop until the time it was delivered.  A few of the before/after shots are almost shocking.  New parts rule.  ENJOY

Little By Little: G35 Gets the Job Done

Filed under: Featured Cars and Projects,Performance
by Forbes @ 8:47 pm on September 25, 2009

The problem with hanging around all of us at ZCG is that you get the urge to modify your car whenever you see something else cool in the shop.  I’ve probably heard it a hundred times, “Yeah I think I’m just going to put a pop-charger on it for a few extra horsepower and then I’ll be happy.”  This sentence is usually followed by a chuckle from everyone within an ear shot.

Inevitably it begins to snowball.  “Hey Rob I bought some wheels (VOLK SF Challenge in gold), can you guys install them?”  Followed by, “Wow the wheels look great but what can we do about the stance now?” (Tein FLEX coil-overs with Hotchkis swaybars) Everyone continues to chuckle because we know where this is heading… FORCED INDUCTION.

That is exactly how this build went, well in a little different order but you get the gist of it.  This Rev-Up Equipped (2nd gen VQ35 engine with dual variable camshafts) G35 has come back to us one more time to receive the final phase of its build, maybe.

The owner of this beauty has chosen to do one HUGE final step, everyone gets a little impatient when they can see the end in sight.  Here is the rundown on what we have just completed:

Jim Wolf Technologies Camshafts

Stillen Headers

Bassani cat-back exhaust system

ZCG Custom Oil Cooler

ZCG Custom Cold Air Intake

Defi Gauges and custom mounting for the controller

Tein EDFC (Electronic Damping Force Controller) with custom mounting, the car already has full Tein Flex coil-overs and Hotchkis sway bars

Sillen Series Two Front Bumper with splitter

Oh yeah…

and a Vortech Engineering Polished Supercharger kit

Even after all these years of installing Vortech supercharger kits we can still be caught off guard by the power they produce and the high quality of their product.  The fit and finish of the product is top notch witch goes a long way in a highly involved build such as this one.

From the dyno graph here you can see the tremendous jump in both horsepower and torque thanks to the exhaust, camshafts, and supercharger upgrades.  417 horsepower at the wheels is nothing to joke about, in fact we ended up pulling a couple degrees of timing after the 417 run in the best interest of reliability.  The car was delivered to the customer making just over 400 when all was said and done.  High numbers are great, but making them last for years to come is better.

Oh one more thing, It made this power through the stock cats!!!  So there is more power to be had if we switch to high-flow cats or test pipes, if he decides it is necessary.

You may have also noticed our new mounting locations for both the Tein EDFC controller and the DEFI gauge controller.  This new install is super clean and has almost a factory feel to it.  Pretty sweet.  We also decided to change the mounting of our ZCG oil cooler on this build to maximize airflow from the new Stillen bumper and to improve the overall aesthetics of the front end, this too turned out really well.

Other than that there isn’t really much to report, that is if you think that tire shredding power isn’t news worthy.  My prediction for this customer’s next upgrade is a new set of rear tires in a month.  See you soon friend (chuckle).

G37s Jim Wolf Technology POP Charger Install

Filed under: Performance
by Forbes @ 5:26 pm on July 29, 2008

One of our first G37 customers brought his car by today for a JWT pop charger install. The Jim Wolf product is top notch and as always the install was trouble free.

We made two base-line dyno runs with a best of 279 horsepower and 234 ft/lbs of torque. From the dyno graph above you can see that the torque remains extremely flat across the entire rev range and the overall gains are very nice for only adding a POP charger. The final numbers are 288 hp and 240 ft/lbs of torque.

There are more pictures after the “Read More” jump.
