Any differences between s4 and s5 turbine shafts and wheels?
Shaft diameter and wheel dimensions are the same?

I'm attempting to build an s5 hybrid, but one of my turbine fins is chipped... So i need a replacement. Just need to know if the shafts are interchangeable from one to the other.



thanks

 

do you have an s4 or an s5?
witch blades did you want to use on what housing?

 

Same as far as I know. The only difference is the turbine housing and manifold.

 

the only difference between the 2 turbos is the turbine housing for the wastegate and inlet. they are both Hitachi HT18s turbos so the turbine wheel and compressor are identical.

 

Great. Thats just what I needed to hear. Thanks guys.
