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

Barring the DOHC ZC, a SOHC ZC or D16A6 would also be good choices since they'll be almost direct drop ins.

If you want as cheap as possible, get a D16A6.

I personally wouldn't use a Y7 for anything other than misc. parts. You don't want a VTEC engine unless you can afford to run it properly.

The A6 will still be the easiest. The only thing you'll have to do is the MPFI conversion.

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.

Oh yeah. It's a habbit now, I think.

Yeah, the A6 will be a direct drop in. Make sure you get the transmission for it, too.
