Which 20v turbo???
 

There looks to be 2 types of 20v turbo engine. The main difference looks to be around the inlet plenum and associated plumbing. One is the ABY. Whats the other one called?

1.What are the differences?
2.Which one is the best to use and why???
3.Will either bolt straight up to a B2 90 quattro gearbox or am I better off using the 6speed box??

Thanks,

One above is AAN its what im using in Quasi.

Lower is ABY.

Intlet manifold on the ABY is more compact and better suited to a straight swapover than the AAN which is fitted to the S6, essentially theyre the same engine.
