A buddy of mine (also a customer at the shop I worked at)
94GT, R302 block based 331 stroker, VIctorJR heads, TFS Track Heat intake, F-303 cam, HP Stage 3 76mm single turbo, tremec tko600, spec stage 3 clutch, complete fuel system (60lb injectors, twin extrnal 255lph walbros, rails, etc).....car made over 600rwhp...custom tuned with a Tweecer RT by the owner (idles like a Mercedes and goes like a raped ape)
The car driven everywhere and anywhere and whenever possible....hes gone to the US and back...various number of trips to his hometown and back (300miles each way), various high speed runs with Porsches and built C5 Vettes....runs like a swiss watch....
Only major things hes had an issue with is, hes gone thru a cpl clutch cables (they fray due to the heat, but it seems to be solved now), and it used to have a SPEC Stage 4 in it before, and after getting excessivly hot, the disc would "fuse" itself to the flywheel, has a happened twice, so as of last week a SPEC Stage 3 lives in there....
