Thanks dude
That was really helpful man thanks I was sweating it thinking this was gonna be an absolute massive job but feeling a bit better about it now I think from the information given so for in gonna try go for a st170 engine with the ib5. I'll look into beefing up the clutch and making it a bit more resilient.
As far as wiring I was contemplating a stand alone one could anyone recommend any good reasonably priced units ??
