I just picked up my '06 impreza 2 days ago and i love it. Its not a WRX =( but it was all i could afford and it only had 36k on the clock. I do have plans for i though. I want to build it up to WRX status but i don't really know where to start. Do I need to modify anything in the engine so it will handle boost? I'll probably start with exhaust but i haven't been able to find anything on the net for an impreza. Everything i have found has been for the WRX or STi. Will exhaust parts for the WRX fit a regular impreza? Also, i've read a few things about the tranny in the '06 and they all seems to say thats its a bad tranny (tranny is made of glass). Any truth to this? Thanks in advance.
