Thats great info!

The B18a1 is obd0 which i would probably leave if we did put that into there, but i'm thinkin that the D16a6 would probably be the best bet for him as far as cost wise & probably less wiring.

The d16a6 is obd0 still.

When you said about wiring up the MPFI, i'm guessing that this is because the 91 dx is probably dual point vs. the d16a6 which i'm sure is multi-point. What all is involved in that?

if anyone has a complete list of details on the D16a6 into the 91dx please post!
