88audi90_Q

u kno the link u gave me?
wut is it reffering to? , just changing the cylinder head, or is it talkin bout putting a whole 20v engine in?
and about the AC in ur link, i was reading, it says if u do the swap, u have to get rs2 parts if u wanna keep ur AC, but i already disconnected my a/c, so it wouldnt matter

OK, for starters, a 10vt block with ANY 20v/20vt head will result in a horribly low compression ratio. It will not run correctly it is so low...

Anyway, I would NOT use the urq 10vt engine, as it needs updated (oil-only turbo, solid lifters that need shim adjustments periodically, etc), and the wiring of those things (for the most part) is crap. Get a 10vt from the '86-88 5kt/tq 5spd or the 89-91 200 5spd cars. Much better engine, better wiring, better ECU.

If you want a 20vt, just get a 3B or AAN, because it takes a pretty good bit of know-how to make your own "hybrid" 20vt based on the 7A and NF/NG engines.
