Ok, so most of my posts have been in the older gen forums for mainly two reasons: One, ive only really had issues with my 87 RX, and Two, the very little i do know, is about EA82's and ive learned 95% of it from USMB.
With that said, a friend got me in touch with a guy selling his 02 WRX wagon. He believes the turbo went out because of the Banjo bolt filter issue. I'm still waiting for a chance to get more info from the guy and go up there and check the thing myself - again. not like i think i know more than the owner, i just don't want to overlook anything.
I need help with a couple of questions. First, whats the best way to find out if it IS the turbo, and how would go about finding out if its an oil starvation thing or if it just swallowed the up-cat?
Then figuring out the issue, whats my solution:
banjo-bolt problem - remove banjo bolt screen, replace turbo and oil? is an engine rebuild necessary? how extensive? new-shortblock-extensive rebuild?
turbo eating stuff issue - rebuild? or complete replacement?
The main issue is figuring out the extent of repairs needed in order to weigh the costs. Ive searched a few forums and it always seems there's the the "my friend just got a rebuilt engine for $xx price." Well, i need "xx price from yy source in Washington", the kind of information i can use to find parts, not just what prices are possible.
this is all based on the little i know about WRX's and Im sure im overlooking other possable issues. My problem is, someone gets me started on one train of thought, and suddenly all the symptoms point to that issue. Any enlightenment on the subject will be very much appreciated.
