Well to make a long story short, sunday we some how managed to over boost the car and cracked 2 of my pistons, so i was advised by the mech to sorta get the 2.5L block with forge pistons. Hopefully in about 2 weeks, i can get back my car and have it running smoothly as it was before, but i'm telling you its hurting me, all that hurt will be gone when i get back the car tho. ha ha ha.

Just one question tho, would i have to change the ecu or anything else, since it's goin to be 2.5L engine or need some sort of fuel management thingy or any advice would be appreciated.

 

I just did the same swap last week this is what you need. Sti injectors, fuel pump, turboback exhaust and I used the ecutec to tune it. The car is so fast its not funny the little 2.0 turbo spools so fast im getting the car 0-60 in 4 flat. Im getting a bigger turbo so the top end matches the bottom end power. hope that helps.
