well I rebuilt my engine, acutally I rebuilt the one that came wiht the car, got it bacj int he car, and tuned whte megasquirt to 14 psi, as this engine is a 9.5:1 CR where as the turbo engine I was putting 20 psi to was 8.5:1, it feels down on power, and takes linger to spool, but got it running saturday and autocrossed it sunday and it didn't blow up ;) although it does smoke off throttle?
