pistons, rod bolts, machining of crank, reco of head, cams, tuning + running in, maybe a cylinder bore, maybe GTR rods...the list goes on and on...
oh and the clutch that I replaced like 6 months ago is apparently fubar, it has blistering and heat damage, and the flywheel needs machining:(
and after all this my car will still be runnning the stock turbo...so I don't think a metal headgasket fits within my budget... the cams however will help performance...so there in;)
