If you are referring to the original Euro-R IM, it is only meant to bolt up to another Euro-R h22 cylinder head. Of course, with modifications done to your h22 cylinder intake ports, you can bolt it on as if it was meant for it, unless you have PDE Euro-R head already ignore this post. I suggest however, you consider Rosko version of the Euro-R IM has made the specifically for the Euro (type-s), blacktop (h22), bluetop (f20b/h23). The performance of his intake matches and possibly exceeds the the original.
