Is it possible to put a R56 turbo manifold on a R53? Just something I have been curious about.

 

With most things that are built or manufactured, you have enough money you can do about anything.

 

It is a different engine.

 

Short answer no. It will not bolt on.

You could cut the head to manifold flange off and make a custom flange and mod the runners to match up. But at that point its basically a custom piece. And im gonna guess that the r56 manifold is cast. This is extremely hard to find someone that can do a good weld on cast metal.

You could maybe make some sort of spacer adapter, and i know there are r53 turbo conversion manifolds available already anyways.
