Goodluck, i hope you dont go through the pain i had too. It's going to hit a 20k rebuild in january... Mine WAS stock till it went puff. head gasket, cracked pistons and shattered valves. Had to do a complete bottom and top end rebuild. Hence i went all out and put slightly bigger pistons in, upgraded the fuel system etc. had it back for a week and blew a turbo (i was a noob and didn't bother replacing the stock turbos yet) as i didnt have the cash to replace them at the time. Back in it went. Put -7's in it. Picked it up last night. Still running wastegate as im still running the engine in but should be a bit of fun when i can give it a bit..
