Yes it will
But im not 100% sure on little differences(port sizes valves ect)
Someone correct me if im wrong.

Yes it will fit, in fact there is no turbo head and non-turbo head. They all have same valve sizes (except that the some of the 15M heads have 1-mm larger exhaust valve and some don't) but the combustion chamber volumes and shapes differ. The E15ET always has a 15M head, some N/A:s have that same 15M head. What head have you got m8?

I would speculate that the different chamber volumes may have differing impact on performance, but I think E or C or any other of the n12turbo-forum engine experts can comment more on that.

E has made a list of the most common E15 heads. Check out E's list of E15 heads for details (valve sizes etc.):

Yep. For example, I recently bought a head gasket just in case I happen to need it, and it says on the package that it will fit both N/A E15 and turbo E15 (and also E16).

Yes they fit directly, no difference there. The cam pulleys might differ in looks but they all have the same number of teeth and the same alignment marks. They can of course be interchanged.

Examples of E15 cam pulleys; older cam pulley on the left, newer cam pulley on the right:

Wise thinking.

NP!

The guys explained it all to me when I started digging around for information about the heads for my own E15ET project. I actually thought the heads differ more than they do. See the thread I started:

Your RC will fit. You will just have to swap over the threaded rods from your turbo head to the new one.
