If it was marketed as a Spec R dual bb turbo, then there can be a dispute. It is pretty evident that wasn't the case though.

All this crap over 10-15hp! I guess he needs to hear everything twice...

S14 vs. S15 T28 turbos!!!!!!!

S15's only came in TWO trims. Spec-S and Spec-R. So for you to say "non Spec-R" tells me you mean Spec-S. And if you knew anything about anything Spec-S models are NON-TURBO which means no T28 at all.

The difference in turbos is based on transmission and transmission only.

14411-69F00 is plain/ball bearing (S14 Kouki turbo)
14411-75F00 is plain/ball bearing (S15 Spec-R AT only)
14411-91F00 is ball bearing (S15 Spec-R MT only)

edit:

The part number below the main part number above will indicate whether or not its plain or ball bearing.

466541 = ball bearing
466543 = plain bearing

So if you have a turbo with part number 14411-69F00 and below it says 466541-, then its an S14 Kouki T28 ball bearing turbo.
But if you have a turbo that says 14411-75F00 and below it says 466543-, then you have an S15 Spec-R AT T28 plain bearing turbo.
