Right mofo's, I know scutch has swapped his engine and someone else has a 5efe in their sr. Where did you source your engines from and what sorta prices am I looking at? I'm considering another 4efe as mine has done big miles, or mabye just another cylinder head and rebuild the top end with sera cams and shims while im at it. Or the other option is a 5efe depending on cheapness, and obv a turbo is an option but in reality i cant afford the later one (never stopped me before ) any info would be good guys. Cheers Stevie.
