I'm in the same pool as you man, 94 DX. I'd say swap it. D series motors are no good, im my opinion at least. I'm doing a b16a2 or b16b swap over the summer, just because I'm opting for a strong B-Series that's easy to swap and highly upgradeable, but not TOO much of a b***h on my wallet (b18c5).
I hate to be mean to anyone boosting a D series, but I have yet to see a good one. There's a local guy with a 4th gen Si boosted, and my stock SOHC non-VTEC can keep up with him.
And yeah, I am not the smartest person in the world, but I know that LS non-VTEC motors are better with boost. People have told me that you can in the end get more power for less money out of them, because the VTEC motors are harder to tune turbocharged.
Your car, your decision. I'm 16 and poor, working my ass off for a straight up b16 swap. It'll be quick, not obscenely fast, but in the future I can do more.
