A decent oil pump for a rear mount isn't cheap either. A mail order tune with boost is a terrible idea. So count on some dyno time, which isn't exactly cheap. Cam swap or not, better valve springs are a must for FI. There's another $250ish. The 60e will be toast in a matter of weeks, no way around that. So be looking to spend north of $2000 for a decent unit from a good builder.
