Forged Performance: GT-R Greddy TT Review and Install
We just wrapped up our first Greddy TT install and so far, I'm very impressed with this kit. The fitment was absolutely spot on and superb, and the quality of the components was top notch. The kit, as most of you know, features the TD06-20G turbocharger which can support 800hp easily. The car made 610whp@17psi and there is much more left in these turbos. As a reminder, or Dyno Dynamics Dyno reads much lower than most. A stock GT-R produces about 380-390whp on our dyno, for reference. Each PSI yielded a significant increase in power. Here are a few pics! Also, wanted to give a tip of the hat to SP Engineering. They did the initial install of the HKS GT570 kit and the workmanship and attention to detail was outstanding! 
The car is a beast!
Modification List:
Greddy GT-R TT Kit
Greddy GT-R Aluminum Pipe Kit with RZ BOV's
Greddy Front Mount Intercooler
HKS EVC 6
HKS Knock Amp
DW 950cc Injectors
HKS Superfire Racing Spark Plugs
Twin Walbro 255 Fuel Pump Assembly Upgrade
Custom Cobb AP Calibration tuned by Sharif

Oh lawdy! What a mayonaise! Better power curve over stock I assume? Couldn't just just squeeze this out of the stock turbo's (albeit higher psi)?
Looks like most are tuning off the Cobb, I guess the software and interpolation from this don't require the use of an aftermarket ECU

How much do you think the stock motor can handle without it being a ticking time bomb Sharif?
I still remember all of the talks and worries about the strength of the motor when it was released.

The Cobb Pro Tuning software has come a long way and it's currently running all of the highest powered GT-R's in the world. Stock turbos run out of steam at about 525whp on our dyno, and and we have to run them at a much higher boost levels and out of their efficiency range. We are barely breathing on these Greddy turbos and making over 600whp on pump.
