Hello everyone!

Just wanted to share a recent project we just completed. For this project we decided to adapt a Greddy TT Kit from the 370z and install it on a G37 Coupe. Many of our customers have long wanted another TT kit option for the G37 and with Greddy's support we determined what changes would need to be made to the 370Z kit in order to adapt it to the G37 Coupe. Turns out that almost no adaptation was required aside from relocation of a few items due to the automatic transmission coolant lines. We also had to fabricate a bracket for the adaptive cruise control distance sensor. It's amazing how well the kit fit when it's not even technically designed for the G37 Coupe. The kit shipped the day we ordered it was well packaged, and was missing zero parts. The kit does not require any special driveline spacers or aftermarket steering couplers, making installation a breeze. We managed to achieve 440whp on our dyno dynamics at a very conservative wastegate pressure of 6psi. The big 20G turbos can produce 700whp+, but still spool very quickly and are happy at wastegate pressure. As always, I calibrated the factory ECU with UpRev's Pro Tuner software. This particular vehicle is an 08 G37 5AT with about 40,000 miles on the odometer. The owner lives in Texas and drives the car every day, so reliability and OEM look feel are extremely important.

Seriously this is one of the best looking cars that's come out of our shop. It's a perfect combination of power and class. I didn't want to see it go, but alas, the client flew in from Texas and proceeded to drive it straight home 12hrs without missing a beat. Next upgrade is a Big Brake Kit!

Simple, reliable, clean, and undetectable from inside the cabin.

Looks awesome! Love how the intercooler looks with the cruise control in front the intakes thru the vents.

 

wow, that is definitely a nice car with a nice upgrade. Good job Forged!

Edit: Assuming this goes into production for the G's (or simply just using the 370z's set-up), what price difference will we see when compared to GTM's Stage 1 TT?

 

There you go again Forged, doing awesome and ridiculous stuff and making me want it! Very nice work!

 

General question about the intercoolers.

Since one of the runners of the intercooler is blocked by the bumper does that effect the efficiency of the intercooler to cool that one side of the intake charge?

So will one side have a colder intake temp than the other side?

I don't mean to thread jack, just an observation that I'm wondering about.

 

The car does look excellent.
Does anyone know if the adaptation for this kit to fit a sedan is minor or major?

 

Nice build!

 

sweet! Update us on how the 5AT handles all the power!

 

Dammmmmmit I am so jealous! I have wanted to bring my G up and have you guys TT it ever since we talked about doing the Greddy kit

 

That looks so clean !!

 

very nice... how would this fit on a 6MT? straight bolt on?

 

Nice, the VQ36 are getting more love now haha

 

I like the attention to detail!

Just wondering though, why would the customer go for twin 20G's if he only wanted 400+ whp at 6 psi?

 

WoooooW ..

waiting for some numeric results ASAP !
