There's a bunch of guys around here that know their stuff when it comes to these beasts: Joe Reif and Joe Jr, Ed Brewer(DC Tech) Bryan, Neil to name a few. We normally get together at Hooters to hang out and talk turbos when the weather is nice so you should join us.
It's a bone stock car with 90k miles that looks like it just got oil changes for maintenance. Blew the factory lower radiator hose on the way to work Wednesday, and I think it still has the original plugs & wires. The only mods I can see are oil pressure and water temp gauges, and the breather on the passenger side instead of venting into the turbo. Right now, it has a little of a rough idle, and it has a bit of a tap when I get over about 3lbs of boost.
Obviously needs plugs & wires, probably needs sensors. Running a few tankfuls of good gas with bottle injector cleaner seems to have helped idle a little, so I'm guessing I should run through a can of the real cleaner. From what I have read, symptoms indicate I need an accumulator for the brakes and a TV cable adjustment. Car sounds and smells like I need to get my headers welded too (for all I know, that leak is the tapping I hear on boost). I'm working my way through the infamous "Spring Cleaning" list, and I bought some top end cleaner. I'll probably know more when I'm done with all that.
My father, a fellow GN owner, mentioned that I would probably need to replace my rear main seal in a little while since I switched to synthetic oil. I figure I'll need a mechanic for that one, so I'm asking ahead. I'd also like to just have an expert go over the car and help me write up a grocery list of the work it needs.
