what prefix audi motor?
and a 2.0 head on a 1.8 block will generaly lower compression...

The 2L has bigger intake ports so you would need to use a the audi manifold, but it comes out the wrong side, so you`d need a mk3 one which has a different throttle body. So not a straight bolt on. Better to use the 2L bottom end and your 1.8 head. Bolts straight in and is rapid.

Have to say this because every time I asked about a 2L bottom end i got this response.

"The 2L bottom end doesnt like to be revved"

That won't be so much of a problem if you are running a std head.

If you have one that is ported and polished and maybe with a lumpy cam, then the lack of reviness will show up more.

Can't say I've had that problem. I'm running a 3A 2L, and it's an animal... I'm not sure about a newer 2L running digi though, this 3A runs harder than my 2E ever did...

the audi is a 91 model , joe says there is alot of variations wth a 2 l block , yesterday i set the air flow meter a few clicks and it made a good improvement . i will go for the engine swap with the 2l and i got a set of leather vr6 seats to and tear drop alloys , just need to lower it down
