    well as of today, people are telling me HFs are MPFI, so you should be good there. The d15b is the best choice (performance wise). and if your going to go with a d16 make it a a1, a8 or a9. you can also go with a d15b2 or b6 (not to be confused with the plain old d15b).

    the JDM DOHC ZC will give you the most for your money - better performance than any SOHC D-series and better than any stock B18 - bolts right into your car with minor wiring change at the distributor - use PG7 ECU - best if you can find a Si transmission to go with it

    i dont know how i missed the a6 in my list. the a6 is a peppy engine for a crx. i havent tested it at the track, but my buddy's new crx si FEELs faster than his stripped ek w/ a y7.

    you guys are quick, I know the d15 is the best can anyone tell me a good link on a price? I checked with a junk yard near i live and all they had was d16y7 the whole car basicly for $450 what do you think? in my mind, hp wise i'm taking an hf to a si. can i take the intake manifold and my distributor off my engine and put it on the d16y7 and run it off my ecu? christmas coming soon i have to do as cheap as posable and it's my daliy driver. can anyone tell me if the car is obdo? thanx Bob

    thanx guy, even with d16a6 it all comes down to wiring, i have never done a swap before, to me nuts and bolts are nuts and bolts it all comes to wiring, what engine would be the easyist to wire out of the d-series? so the d16y7 is no good then? thanx Bob

    you are right. i dont know why we are talking about dpfi to mpfi conversion. if you have an hf, it should be mpfi, so a d16a6 should be almost a direct drop in.

    thanx man you've been a real help!when looking for zc's i found a dohc and shoc witch is better? i like shoc a little bit better don't know why , the hp is about the same, i'm guessing that aslong as it is a zc from 88-91 it obdo so wiring will not be to hard, correct me if wrong! has anyone on here done this swap with an 88 hf to zc if so how hard is it? what did the zc come out of, if it's a usa motor i'm guessing not thow thanx Bob
