hi lads i got question will engine from audi a4 1.8 Turbo 1998 fit in polo 6n will it be hard to put it in ? cheers matt

Assuming it's roughly the same size as a IHI engine (1.8 20v Turbo), then yes, it should fit.

There's afew 20v 6n's on here. Engine, box,loom, ECU, basically everything out the bay plus the fuel pumps off the top of my head.

well the audi that the engine is in is a whole complete running car , but is just parked at the yard at my work and nothink is happening with it so i tho i could do little swap

you need one where the engine is mounted transversely or you're just creating a load more work for yourself.
