^ Im looking into this for reliability purposes more than the power. I prefer to have something built to take it with no stress. I don't think our engines will take this much power for long and I plan on having this kit running for years to come.

 

I wouldn't go as far as to say that. With the headgasket you can very safely run 400-500rwhp on stock motor.

The weak point of the motor is not the motor itself, its the tune you give the motor. Get a good tuner, no need for a built motor and it'll last thousands and thousands of miles.

 

You can make a reliable(I use this term loosely, because, we are taking a NA car and adding FI) 475 with a 3mm Head gasket and proper tuning(< key factor). I was doing that number on a ACT clutch and Comptech diff for some time.

Just for the hell of mentioning it, my thread really didn't answer anything except the fact that I'd need bigger injectors, no answers as to any estimates of how much whp I'd gain from switching to a T4 turbine housing with the same boost, no estimates as to how much whp I'd gain from just the full-race intake manifold, nothing like that.

 

Nobody offers them yet.

 

It will be enough to scare you. Thats for sure. Anything over 425 whp in this car is enough to scare the crap out of anyone in this car if your planning to use that power on the street.
