If the turbo coupe rear came out of an auto it has 3.73's, if it came out of a manual it has 3.55's.

I believe the E5 heads are almost the same at E7's, its the 86 heads which really suck. But still the 8.3:1 compression sucks, and I think you would benifit from a good set of heads and a better intake.
