For folks that live in the US, it’s hard to imagine a bigger piece of forbidden automotive fruit than the Nissan Skyline.  The Skyline has never been sold in the United States, yet it’s still managed to develop a fanbase and aura that can easily rival the best foreign or domestic metal. Most of us are familiar with classic Skylines and modern GT-Rs, but the DR30 you see above is still relatively unknown among non-JDM lovers. Reid B. scored this lovely red Skyline 2000 RS-Turbo almost four years ago.

 

The pillarless windows,  angular body shape and killer graphics package create an unmistakable 80’s vibe. We love it!

 

Soon after Reid purchased the DR he started making it his own while preserving the classic OEM goodness. He brought the car to us initially for a dyno and tune after noting that the Skyline had a flat spot in mid-range power delivery. When we inspected the car we found the front suspension was severely rubbing on the tires and this was addressed first.   We installed Techno Toy Tuning (T3) coil-overs with custom springs, RCA’s, Energy Suspension T/C rod bushings and AGX shocks:

 

Although Reid was hoping to fit a 215-width tire up front the DR now sports 225/50/16 Yokohama S-Drive tires at all four corners with great clearance. Watanabe wheels look so right on these!

 

This being a 1983 model, it sports Nissan’s legendary FJ20ET powerplant underhood. Reid was concerned about potential fuel delivery problems and our A/F monitoring revealed lean conditions under load. We discovered a failed fuel-pressure regulator and our solution was to replace and modify a 280zx fuel pump and FPR to fit.  A new oxygen sensor was also installed.

 

Further inspection revealed over-boosting so we lowered the base boost rate with a lower pressure spring in the external wastegate. Dyno results were great and we’re happy to report the DR makes more power at less boost now! Baseline numbers were 160hp/177tq and after 201hp/197tq to the wheels:

 

 

We liked working with Reid as he is the type of owner that wants to bring the car back to life the best he can. Z Car Garage lives for reviving Japanese classics and hearing our customers satisfied with their cars keeps us going. Listen to Reid’s impressions after picking the DR30 up:

Rob,

So the drive home was awesome. I still cant believe it. I didn’t get to drive it to work today but tomorrow for sure. I could drive 80 and then roll on the gas and it would just go and not want to stop. The new front suspension makes the car drive so much better, it doesn’t feel like it rides on cut springs.  I drove the car from Newark to Roseville and it was awesome going from 75-95. I could roll on the gas it would start boost and just keep going. I feel like when I am driving now that I am holding the car back cause it just wants to go and go.  I am still in awe. 

Reid

Enjoy The Ride, Reid and thank you for giving us the pleasure of working on your Skyline!

 

Jason D has been enjoying his G35 coupe since we finished installation of a Momentum single turbo in late 2011. With over 500whp and 315-width Michelins he started breaking the drive axles and came back for some traction upgrades.  We started by installing 900hp-rated axles to replace the 500hp-rated units:

 

 

A common failure that is exacerbated with high horsepower is found in the rear crossmember and differential bushings. All were replaced with Whiteline units:

 

On the power side we installed JWT C8 cams w/springs:

The cams transformed the car and UPREV tuning yielded sweet results on the dyno:

Jason’s G now makes 523whp/432tq…peak gains of 26hp and 54tq! Despite a slight trade-off of power below 3500rpm when boost hits both curves jump with as much as 50-70hp/tq until redline.

Enjoy The Ride, Jason!

 

No, dear readers your eyes aren’t deceiving you! That is a 1972 Chevelle coming out of Turn 9 at Laguna Seca and here is the story behind this icon from the 70’s.  Owner Dave T was scouring the internet for dyno shops when he found Z Car Garage. With an endorsement from his co-worker an e-mail was sent and we happily obliged to dyno the Chevelle. We love muscle cars!

 

Dave had assembled this engine entirely by himself and wanted to see the difference a new exhaust system made. The stock exhaust consisted of OEM cast-iron manifolds, dual pipes w/o crossover and generic turbo mufflers. Baseline numbers were 277hp/326tq to the wheels. The new exhaust system included Hooker SBC headers, Pypes X-pipe and Race Pro mufflers. This helped produce 330hp/356tq to the wheels!

 

Here is a video of the dyno run:

 

 

What we love most about the car is that it was meant to be a ‘grandma’s sleeper’ that could work at the road-track, the drag-strip and as a daily driver.  It still has its original bench seat and column shifter. Dave has logged over 11,000 miles on the motor and recently completed a track day at Laguna Seca!

 

 

A few details on the engine build:

383CI
Intake Manifold-RPM Air Gap
GMPP Hot Camshaft
COMP Cams Valve Springs
GM Bow-Tie Vortec cylinder heads
Compression ratio 9.543
TH-350 (TCI)
3000 rpm flash stall converter (TCI)
3.08 rear, Eaton posi

 

Dave actually built the engine before he found the car. After the successful engine run on the stand, his dad encouraged him to find a car for it:

“He said, why don’t you get a Chevelle like you had in high-school- that was the best car we ever had. I had received a 1972 Chevelle Mailbu from my parents at the age of 16. It was blue with a white vinyl top. I had an accident in it and some time after that the cam/timing gear let go and although I tried to replace it the engine never ran right and we ended up donating it to the high-school auto shop class.”

 

 

He then found a ’72 on Craigslist in un-modified condition, shown above in the original owner’s driveway. The car has been repainted it’s original shade of green, and that’s it. In went the new motor and he’s been driving like mad.

 

Here is Dave putting the Chevelle through its paces at the Sear’s Point Drags (Sonoma Raceway). His first time out he ran low 13’s!

 

 

Thanks for bringing your Chevelle to us we enjoyed working with you Dave!

 

 

Nick P came to Z Car Garage to fix a blown head gasket on his 280zx.  We decided on a full cylinder head rebuild with a revised cam profile from Rebello, otherwise it was built close to factory spec. Teardown pictures below indicate obvious failure:

 

 

The rebuilt cylinder head:

 

We added a new 6-2-1 exhaust header from MSA and finished it off with the ZCG exhaust system:

 

The intake manifold and associated smog/efi plumbing were cleaned up:

 

With the engine freshened we put the Z on the rollers…141hp/142tq to the wheels is healthy!

 

Next we turned to the suspension. Nick wanted us to install his TechnoToyTuning (T3) coilovers, RCA’s and T/C rods:

 

Old struts out and coil-overs in!

 

T3 camber plates up front:

After an alignment and fender roll the Z sits perfectly without rubbing or scraping. We dig the RB-Rs on this!

 

 

 

Dwane has been customer since the opening of Z Car Garage in 2004. We installed one of Vortech’s earliest supercharger kits on his ultra low-mileage ’03 Brickyard 350z circa 2005 and he has been enjoying it ever since.  Almost a decade later forced-induction tuning and support has tremendously advanced and many boosted applications are abandoning the old Split-Second and FMU-based systems.

 

At ZCG we love the UPREV tuning platform and it allowed us to maximize gains from a new GT MAF, larger injectors and upgraded fuel pump.  We also installed ART pipes on the exhaust side and nice cosmetic addition of LED-based headlights:

 

 

On the dyno we picked up 9hp/13tq with smoother delivery throughout the rev range. Mid-to-high gains were significant:

Stay tuned for more power!
