turbo manifolds
 

what is the differince in the exhaust manifolds of the s4 and s5 i am not showr if i am right but the s5 has a t4 flange not showr please help

No, they are not standard flanges, so it cannot fit a Garrett.
They are both proprietary, so get rid of any notion that you can just bolt on another turbo and make it fit.

Both manifolds are completely different!!! Neither is a T4 or T3, its a MAZDA rx7 turbo bolt pattern only and there both different from s4 to s5 also.

not to mention the s4 has the twin scroll, a flapper style door on the inside, used to force the exhaust gasses to be pushed out of the manifold at lower rpm's, used to aid in low rpm boost.
