Yeah from the research I've done I'm pretty sure I can just bolt the ib5 straight to the st170 block. I'm gonna throw a new clutch for safety but thats it I think. Then I have a exhaust shop close by that is gonna fit a universal sports cat between my escort catback and st170 manifold. And with the M.E ecu and loom I think its gonna be pretty straight forward. I'm sure there will he things here and there that pop up but I'll just have to tackle them as they arise haha
