is there any big differences between them??? Is there a difference between HP + or -???Will it mount in the same location or how much difference or mods will have to be done???

 

I know the 2-port wastegate on the S5 is better than the single port S4. Not sure about the turbine and compressor, although the S5 is the one to have, IIRC. I believe they are interchangeable, so long as you have the corresponding exhaust manifold.

 

basically they are the same turbo. the change is that the s5 turbo has a divided manifold, and the s4 doesnt. also the wg thing.



the s5 spools up faster so its the one to have

 

Thanks for the info guys,Im glad i got the S5 rather than the S4!!!
