Thanks for the input..I have a friend who recently put an STI tranny in his 03 WRX. He said that it's not real hard to do but that it does require having some custom axles made because the splines wouldnt work. This guy owns a custom shop and I've seen him do all kinds of engine builds and swaps. I do alot of custom welding for him and I weld roll cages for him..He mentioned that those transmissions weren't that good with extra power, so I'm gonna probably either take the route that man show took or look for a six speed STI tranny.
I should have been a little more specific.My main concern is the engine itself,once I rebuild it with all new forged internals and start putting more power under the hood, I'm trying to figure how much HP and torque to aim at to keep the engine itself dependable and still fairly easy to drive on the street.I do know a lot of that depends on me and how I drive it and maintain it. I think I have read enough info on this site and a few others to make a decision. I should have the rods,pistons,bearings,crankshaft,oil pump and timing gears on Monday. I'm looking forward to get this thing started. Like I said, this is my first Subaru build and I am curious to see how it ends up running against some of the other imports out here at the drag strip..I know they aren't built for drag racing,but they are so much fun..I would love to try some time attack racing if there were a track near me.
