kinda.... the spark plug holes in are different spots which will throw things off a bit. But I'm sure people are using them with no noticable problems.

this recently came up on the www.ausrotary.com forums and it was found that there is an early and a late type of S4 turbo..
the later S4 turbo being the one you can change the back of with the S5 item..

You can bolt the ser 5 exhaust housing on if you want but the impella will have to much clearance from the housing. Which means lag. The only time it will work is if you have a later model ser 4 turbo. It dosent have the shim that the eairly ones had.
The early model S4 turbos have a slightly bigger centre which doesnt allow the S5 housing to bolt straight on unless it is shimmed/sanded...
