Default AMS GT35r Turbo Kit... 482hp 407tq on shell 93oct

I am very pleased with how this car came out, making just insane power for 21.5psi and straight 93oct with no adders with still many stock parts.

Once again the AMS GT35r turbo kit has proven to be leaps and bounds better than the competition, in both spool and power output. To this date its the nicest turbo kit I have seen and tuned... PERIOD.

On the street we're seeing 21psi by 3.9k rpms in 4th gear and 14psi by 3.3k rpms which is just nutty for a GT35r with a .82 hotside.

As for the motor package that we have put together, the principals stay the same as all our engine packages. We designed it to have as flat a tq curve as possible. We will continue to work on the 08 heads as we work with GSC on designing us a set of cams. In the future I would expect the curve on the 08sti's to be even better than previous years due to the dual AVCS on the heads allowing us to get more aggressive with cam selection.
