(yes, I used spell check for interchangeability)

I'm wondering about a few things, which I haven't found while searching yet. Some I'm pretty sure about, others I need confirmation by people who know *for sure*.

OMP - as far as mounting (ignore the fact the S5's are electric) is concerned, all of them interchange (S4&S5, NA and TII) and bolt on to the front cover?

ACV's - the NA and TII are different - but are the S4 and S5's the same, i.e. S4 & S5 NA, S4 & S5 TII)?

EGR valves - S5's have none, both NA and TII?

Sub-zero injector part on intake - on cars equipped, only present on S4 NA and TII?

BAC - S4 and S5 NA the same, S4 and S5 turbo the same?

6PI - Actuators the same between S4 and S5 (6PI only found on NA's)?

No. You have to switch front covers.

Not the same ones...I think. S4 NA has one and S5 NA dont...I think. But the are different for sure. As for TII, I think they are the same....

No. S4 and S5 turbos are the same though, iirc.

No. S5 pulls and S4 ones push.

What, all the experts are answering "how do I learn to drift" threads, or maybe they're all in the lounge? JK, I'm hoping for a little additional feedback. Thanks, F.C.3S, BTW.
