We are putting together a package for 2.5 STi Impreza, to run 450-500 at the flywheel. We will be running 8 to 1 compression ratio and + 1mm inlet and ex valve's. Torque and minimum lag is very important, as it will be used on track, and the track we use is very tight. What do you supply that would fit the 3 bolt IHI flange. Any advise ?

Well there are no Turbonetics turbos that bolt up to the IHI flange however I know Ultimate Racing makes a T3/T4 turbo up and downpipe setup for relatively cheap. I would do something like that and then run a GT-K 450
