hey everyone new guy.
Had some question on swaping? I have a 88 crx hf and i blew the motor! I'm looking at the following d15b d16y7 b20a5 {b20 i have the prelude}I'm trying to do this as cheap as i can .along with suggestions any tech info would be great,wireing,trans,axles, hubs, etc,etc,etc I have been doing reseach on my own and on this site and others i know it's an old topic but i need help! thanx Bob

AHHVTEC

well go with the d15b vtec stay away from the prelude b series

ef8

Go with the D15b,That b20 isnt like other b-series

thanx for answering guys,like i said 88 crx hf, to go d15b or d16 do i have to change wiring ? i think i'm obdo, dpfi if wrong tell me,i looked around and i think i'm right? now if i have to change wires and ecu how hard would it be? does some place sell the jumpers if anyone has a link. thanx alot Bob

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.

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

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 y7 isnt even vtec. its obd2 non vte...not the best choice for a swap.

Oh yeah. Sorry if that looked misleading. It was actually two seperate thoughts.

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

Blanco

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

werd. the dpfi to mpfi conversion is almost as easy as wiring vtec.

thanx guys, can you give me any info on that wiring? if mpfi is one injector for every piston i have that {88 crx hf-b15b6 -1.5 -8v -sohc-pgm-fi- 62hp- pm8}if wrong please tell me, this is all the info i could find on my car? it does't have the up sweep injection,it has a side mount throttle body. thanx Bob

reikoshea

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.

when you say direct bolt in do you mean i can reuse all my wiring?[harness,ecu,distributor] sorry for staying on all these wiring question but were i live i don't have alot of resourses, the guy that will be helping me is a gm guy, so wiring is up to me!
