2nd gen owners,

I am doing a 13btII swapinto a S-2 and need this flange identified.

I was looking at a stock manifold on ebay, and was curious which it is the S-4, or S-5? I was under the impression that the two used different flanges, but having never seen them sitting side by side, not sure which this is.

My flange is the type that looks like a mini t04 flange (symetrical rectangular 2 ports) but there has been some doubt as to where my engine actually originated from a S-4, or S-5 my flange is the other type from the photo.

stock s4 turbo

 

if yours is rectangular then it is an S5(T4 flange), the ebay one you linked is an S4 with the twin scroll flapper.
