The real reason why I'd recommend this setup, though, is because it is cheap and easy. With a couple helping hands, you could do a shortblock swap in a day. There's no wiring, little downtime, and the process is well documented on NASIOC. A EJ251 shortblock should run you around $300.... PM me if you're having trouble finding one.


What sort of power would I be looking at? I'm sure that I could find a shortblock relatively easy. In fact, I found a complete 2001 2.5 engine w/55k for little more than $500. Also, what would my CR be? anything else I should know?
