S5 turbo on s4 engine

[SleepeR1st]

Does an s5 turbo mate up to an s4 turbo engine perfectly without modifying anything?

Thanks, Ryan

Yes, you must use an S5 manifold, but everything else will work. Some mods to the oil drain will be needed, or you'll need to use the S5 stuff. Not sure about oil feed, or coolant feed drain however.......worse case use all S5 stuff.

Swap the oil drain from the S4 to the S5 turbo, and everything else lines up.
