I think I made a huge mistake. I bought an '04 wrx for 8g with 75k on it. Yeah that sounds ok, but I should have researched a bit more, but was sort of pushed into getting a newer car by my fiance b/c I am driving a beater that she doesn't like. I am a vw guy. So I'm not afraid to work on my cars. The car I bought has a different turbo, downpipe, exhaust, and probably a couple of other things. I think the P.O. put the turbo from an STI on it, but then ran out of money when it came to do the fueling. It runs strong, but it does have a check engine light on which scares the poop out of me now that I have done some research. He gave me yellowtop injectors and was suppossed to give me a walboro fuel pump with the car. I think that if I get this done and a tune I should be safe. He did mention a piggyback being installed also. After doing some reading I think I will most likely have to put a fair amount of money into it for it to be a safe and reliable car. I am near Wheeling, WV and would appreciate any help that you have to offer. I'm going to start collecting pictures and part numbers of everything on the car so I can be fully aware of what I have got myself into. Any other advice would be awesome. Sorry for being another ignorant noob and long . Thanks for any helpful advice. If I stay out of boost will I be ok to run the car to a tuner or my garage?
