so im looking to part ways with the rs and the previous owner actually wants it back!! so im in need of a 4 door due to growing family and such, at least i tell the wife that...i just want boost...so ive been talking to a guy in NH that's got an 02 wrx with mods that needs to get out of his loan. Seems to be in good shape other than a boost leak that limits it around 5psi he says. All i really want to know is how hard is it to find such a leak and what are the common issues with that year car???
