Did you figure this out yet?
I'm kind of in the same situation. I have a 90 Teg with a b18 and a 92 Civic with a d15. I'm just thinking of down the road swaps that are possible with the parts I already have-everything staying stock. Plus the fact that I have a ton of d series parts!
I have three d15b7 ECU's (manual tranny) if you decide to do the d swap. With that swap what else will you have to swap-like mounts, hydro or cable shift, axles etc?
