This gorgeous LeMans Sunset 350z has been with ZCarGarage for a few years now. Owner Steve B. came to ZCG in 2010 for a full Vortech Supercharger kit install with 43k miles on the odometer. Since then he enjoyed the boost in power and participated in numerous track days. This Z gets driven hard! Forced induction is addictive and like many others Steve desired more power, ZCG to the rescue…

…The Vortech V3 kit was treated to a new 3.12 pulley and the engine got a host of go-fast goodies including a set of JWT S1 cams, UpRev MAF GT Sensor, RC Engineering 550cc Injectors, 3.5″ custom cold-air intake, Motordyne MREV2 Lower Plenum + Spacer, Unorthodox Racing Pulleys, DC Sports Ceramic Headers and a Bassani cat-back exhaust.

With all of the parts installed it was time to dyno tune. Rob’s UpRev tuning yielded impressive gains of 72hp and 40tq at the wheels for a final output of 436hp/359tq! Power delivery is also improved with hp/tq climbing steadily throughout the rev range:

Steve’s drivetrain and suspension also got some love to keep up with all those track days:
Drivetrain:
Quaife LSD
NISMO Differential Cover
Injected Performance Differential Brace
Energy Suspension differential bushings
IPP Chromoly Clutch Pivot Ball
Suspension:
Tokico D-Spec Shocks/Struts
Tokico 375lbs Springs
Stoptech Stage 2 Rotors, Pads, and Lines
Hotchkis Front and Rear Swaybars
Kinetix front camber arms
SPL rear camber arms
SPL Eccentric Lockout kit
Energy Suspension bushings

That killer stance is accentuated by some beefy Enkei 18×9.5 and 18×10.5 (+15) wheels with 275/295 tires.  Subtle bodywork mods include a Top Secret Carbon Fiber Splitter and rear spoiler; I love how uncluttered and simple this Z looks!  Steve gets all the credit for doing his own interior mods like the MOMO Millenium Evo steering wheel and full stereo/speaker upgrades.
Look for Steve out on the track, but you might have trouble catching this 436whp LeMans Sunset Zed!

Scott S has fun with a new Ferrari 458 Italia at Infineon Raceway in his Green 350z…turn up the volume and listen to Italy’s latest supercar as it accelerates on the straights!

Eventually the Ferrari driver gives Scott the point-by…you can run but you can’t hide from the GreenZ

Here is Rob with another great forced-induction story:

Bob H. is a long time customer of ZCG. He blew his engine a year ago during a spirited track session at Thunderhill Raceway. Bob decided to come back to the track with added engine strength and something to help him get from corner to corner quicker.

He did his homework and purchased some forged internals and built an engine with lower compression. Bob did all of his assembly work for his engine and installed his own GTM DE twin-turbo kit in his garage at home. GO BOB!

Once the engine was broken in and the boost controller hooked up, he brought it to ZCG for the icing on the cake. We installed a PMAS maf and custom tuned Bob’s set up for 12.5 psi. This G is track ready to run with any modern day supercars…

12psi:

Jason D. is a long time customer and friend of ZCarGarage. During the last year he spent time researching and patiently selecting parts for his build. The G35 Coupe features some really cool stuff including a  GTM Stage 1 short block with a set of Rebello prepped heads and GTM Stage 1 turbo cams.  Forced induction is provided by a Momentum Performance single turbo kit with their ceramic-coated headers.

Jason chose the Momentum kit for several reasons but one of the most attractive is that the kit can be installed/serviced without removing the entire engine from the car.  A host of supporting parts were installed including:
-600CC injectors with a GT Maf
-Upgraded fuel system
-JWT 50/50 clutch and JWT Alum flywheel
-Greddy Profec B boost controller
-Custom exhaust with Hi-flow cats

Below, you can see how the exhaust is routed from the ceramic-coated headers to feed the turbo on the driver’s side, a close-up of the crossover, and the downpipe. Plenty of piping and it all fits in such a tight space!

The finished install with wastegate, BOV, cooling lines, and stealth FMIC:

 

So how does the single turbo kit perform? When pressing down on the Go pedal you better have both hands on the wheel. At 12psi it laid down an impressive 505hp/506tq at the wheels!

One of my favorite things about Jason’s G is that besides looking handsome it’s completely unassuming in Desert Platinum. Can you tell that is has literally twice as much power under the hood?

The neutral color, mild drop with HKS coilovers, low key SSR wheels and brakes(Stoptech) all make it difficult to tell that this G might be hard to pass up in traffic   With a Quaife LSD and 3.36 gears from an automatic G the massive 315-width tires light off like they are 205s!

Rolf J is a ZONC member and used his winning raffle prize for a little ZCG dyno love. When we baselined the car we noticed the graph was very shaky and looked like a lack of timing:

Sure enough we found a knock sensor code stored. We removed the intake to gain access to the sensor and found a mouse had chewed on knock sensor harness wires. The knock sensor and harness were replaced and the Z was back!

And icing on the cake, Rolf’s Z got UPREV’d to the tune of +9hp/8tq at the wheels…

Rolf was happy to feel his Z stronger than ever:)
