OPC prices WOW as others have suggested I would heading towards Hartech, Ken at 9E, Autofarm and Sid at Porschetech all great reputations . OPC are just fitters of parts IMHO not mechanics as has been said by others Hartech offer many options to repair the parts that actually that are failing unlike OPC who's blanket response is fit a new engine
good luck you may find that these guys offer you some different options other than a complete new engine :dont know:
