We were recently contacted by Sharrod, a long time customer of ours for another round of modifications on his 2009 GT-R. Previously, he had a CBRD 76mm y-pipe, a Cobb AP, and a Forged Performance custom tune. Although he was very happy with his current setup, he was ready for some more power. The initial plan was to bring the car down for a handful of bolt on upgrades and retain the factory turbos. However, upon arrival we discussed his power goals and his expectations of what he wanted out of the car. We concluded that a turbo upgrade was in order. The car is used almost entirely for daily driving reflecting the nearly 30,000 miles on the clock, so response was a big factor. Fortunately, we happened to have a set of AMS turbos in stock. Sharrod agreed to the upgrade and we quickly got to work. After about a week of hard work and late hours the installation was completed and ready for Sharif to work his magic. With Sharif pecking away at the keyboard before his flight to Dubai and Kuwait (tuned 12 GT-R's on that trip), the end result was 676 whp/93 octane as measured on our low reading Dyno Dynamics dyno. For reference that is about 130whp above our FP600 setup, and about 280whp over stock! Sharrod's GT-R has been transformed from a tame fun car to a daily driven street monster. I'm sure the new power will take some time to get used to. Modification list and pictures below!


• AMS Front Mount Intercooler
• HKS Intakes
• AMS Alpha 9 Turbo Kit
• Tial Blow off Valves
• Forge Motorsports Wastegates
• AMS Downpipes
• Injector Dynamics 1000CC Injectors
• Deatschwerks 300lph Fuel Pumps
• HKS Legamax Exhaust
• Forged Performance Custom ECU Calibration

Aside from power increasing modifications, we also installed:

• Michelin Pilot Super Sport Tires 275/35/20 and 295/35/20
• AP Racing J Hook Rotors Front and Rear
• Endless MX72 Brake Pads Front and Rear
• Forged Performance SS Brake Line Kit

Here are a few photos from the install process and a photoshoot that I did for the customer.

 

awesome. any modifications to the transmission needed for this?

 

Nice job.
Are you going to try to run some vbox times?
That is a great dyno curve-this car must pull very hard!

 

We usually suggest at least a stage 1 transmission upgrade with this type of build, but with the budget in mind the customer decided against it for now. It will be coming back to us at a later date for trans, suspension, and wheels/tires.

No vbox times planned for this one right now. The car is safely back in the customers hands. We will try to get vbox times in the future on similar setups.

 

Thanks for sharing! I absolutely love these types of posts with great photos showing the process. It's one thing to see the finished product but I really enjoy seeing the build process with photos.

 

How is the owner liking the Michelin's compared to the Dunlop's or any other brands they tried before?
