hello i have a 6speed tt j spec and i have a compleet euro spec engine with wires (?harnes?)turbos ecu...
I want to swap tje euro spec engine into my j spec supra
what are the problems that could come up during the swap

the only thing i know is that the downpipes are different:
(????,is this becaus the steering wheel is on the other side?????)
does a j spec downpipe fits on the euro spec engine.

the exhaust from a j spec doesn't have a egr system could tis be a problem with the euro spec engine for the emission??????

With kind regards Stefan
