just to clear this up the t25 is a great turbo for his sort of application is has little lag and its great for getting 6 to 8 pounds fast, go and buy yourself some carbide burrs and port the ex housing and flapper this will make it even better, as far as aftercooling i have had 9 eagles from 300 to 700 HP i have never had a fmic running the cheapest alky kit will do 100 times more than the biggest fmic, i am not going to explain how it works go can go find that out on your own, i can build you the best kit with an electronic controller for about 500 bucks, if you know your $hit you can tune your car to just about any boost level and have 0 yeah thats right 0 knock. best of all running water will steam clean your valve components at the same time lowering your egt slightly and your intake charge temps drastically prolonging the life of your engine, but beat of all no fmic= sleeper=badass
