I have an '03 Impreza WRX wagon. I'll have to post pics of my car when I get it back. I just had a piston fail, and I'm looking at upgrading the engine to a 2.5L engine, as one of the mechanic's at Group 2 said "the saying goes: there is no replacement for displacement." He advised me to get a "complete" engine to install. There'll still be more, clutch, fuel injectors, fuel pump. I'll do the TMIC and turbo later. I was always planning on upgrading the engine. I've put a Cobb downpipe and Borla Hush (not so quiet) catback. Stage 2 firmware. I recently picked up a short ram intake, but haven't installed it as the failure just happened. Oh well. This is just accelerating the process, expense, and most important of all: the fun!
I'll just come out and say I'm a newbie, and I'm hoping to get some useful help here. And one day when I do know what I'm talking about, help other people just starting out.
