Can’t find s4 na housings. What are my other options?
Along with that what do I need to know about my other options? I’ve read that s4 turbo housings can be used and that there will be issues with the acv. And I’ve read that two of the same s4 housing can be used in both positions, using 2 front housings or 2 rear housing (Mazda discontinued s4 rear housings this is my issue). Will s5 na housings have issues?
If I use s4 turbo housings I will use freeze plugs and I don’t need to pass emissions btw
apologies if making a new thread for a question like this isn’t preferable

S4 housings
[I have a pair of S4 housings that I am not using. What kind of build are you doing?

S4 and s5 housings have different spark plug hole locations (I believe for the trailing plugs).
s4 t2 housings will work, they do not have the diffusers in the exhaust so it’d be best to get a t2 housing and a t2 housing exhaust port so the flow is matched.
so it really depends what ecu you’re using to dictate if you can run s5 housings instead, if you have the ability to tune the spark timing.
