The new housings are turbo, Finn. Yes, the
NA's has splitters which reduce the noise level by 8 db according to the Mazda
data I have seen. However, I am also certain there is some power loss with
the splitter given that level of noise reduction - probably more at
the higher rpms than the lower. In any case, since I ported the
secondaries - decided that going with an NA housing would just put more of a
restriction on the gas flow when I was porting to get more gas
flow.
I don't have any real data to back up my assertions
about power reduction - just my intuition.

housings
Hi Ed, I missed one point. Are the new housings NA or
turbo?
If turbo, why? The NA are supposedly more quiet due to the
splitters.
