S5 Manifold and Turbo on S4 block?
it must be possible but is there any modifying ill need to do, and how hard is it? does anyone have a writeup of some kind. im getting boost creep so im going to port the S5 wastegate, and since the S5 turbo is a better turbo anyways ill just throw that in instead of my S4...sound like a good idea?

well it looks like ill port my S5 wastegate to 40mm, then ill need the manifold gasket and a new turbo gasket...
im gonna have to order the new turbo gasket from mazdatrix though...thats one gasket i dont have...or does anyone know where i can get one for less than 50 bucks?
-Matt
after that comes Walbro 225lph fuel pump, and if im boosting too high a 2 inch exhaust restrictor plate...
EDIT: Its only 33 dollars for the gasket on Mazdatrix.com

I'm looking into doing this same turbo swap. Just curious if the S5 turbo and manifold are all that I will need to swap them onto my S4 engine. Any more insight would be greatly appreciated.

I have personally put a S5 turbo and manifold on my 87TII I just had to swap the s4 oil lines on to the s5 turbo, and there is two vacuum lines to plug, thats all I remember doing it all works fine no problem, didn't notice much performance increase, I just know I have a better turbo and my manifold is no longer cracked

I second NZConvertable because I have done it personally, S5 and S4 lines are different lengths so you got to use S4's lines on a S5 turbo&manifold on a S4 turboFC engine
