Using a S4 turbo on an S5 manifold, will it fit?
 

I know that the manifolds are significantly different between S4/5 (Thanks ReTed!, but are they radical enough that the S4 won't bolt up to it? I have a S4 turbo already, and a lead on a S5 manifold at a great price, but no sense buying a S5 mani, even at a great price, if it won't work ;)

Thanks!

No.

the exhaust manifolds are different, and wont bolt together

completely different bolt patterns.

Righto, thanks for the heads up, guys.
