S4 NA center iron in turbo engine
#1
I need a center iron for a TII engine. I have a stack of NA irons but none from a TII. The engine will be street ported so the stock port difference is irrelevant as well as any differences in emissions ports. Shouldn't be a problem should it?

Check that. Found a nice S5 NA iron in my stash. Saves having to plug the EGR port. Visually they appear identical to the TII iron. I understand the casting around the closing edge of the port is different. Other than that?

Isnt there a bolt hole missing in the N/a iron for the manifold? Right above the runners?
Good call! That's easy enough to take care of. Anything else?

I've gotten ito the habit of using NA TB necks on the end of turbo intakes when building custom IC plumbing. This is another on of those cars. The only issue with using the NA neck is that it runs right across the stock oil filler. Easy enough to pop it out, cut it up, and weld it back together for clearance.
