so I'm doing my first swap and interested in the OBD1 B20 (out of the CRV, 146BHP according to HMO i believe...is that true?) I'm new to the Honda Scene and got a hand-me-down CRX from my dad who purchased the car new in 90. how difficult is it to switch from OBD0 to OBD1? I looked at some write-ups already but due to my Noob status...I'm afraid to switch...maybe just going for a B18 OBD0. thanks in advance.

Its not that bad, since you are purchasing an OBD-1 longblock you already have the distributor, injectors, and usually the oxygen sensor. You can either purchase a ready made jumper harness from Rywire or you can whip out the wiring diagrams and D.I.Y.. Either way, it's not that bad.

 

any recommendations OBD1 motors? I'm looking at the B20 for its torque.

 

im looking into getting myself a b18b, was told its better if you have plans for any future turbo plans.

 

if you go with rywire for the conversion harness they make a distributor adapter as well, which means the only real wiring you would do is the oxygen sensor.


i think the b20 will keep you happy for a while being as it is your first swap. try an find a B16 (y1 j1 or s1) trans for your swap, along with a nice header and exhaust. its a great combo for auto-x, lots of torque and short gears


BTW, is you CRX MPFI (Si or HF) ??
if not you have to convert that as well.

 

good ****, i got a hand me down 89 crx too. think of do the same swap. My problem is that all my wires are hacked up n im starting fresh all new wiring. i suggest that u do the same.

its an SI, so MPFI. rywire seems the best way to go. thanks for the advice.

 

Rywire is the best, hands down. They give you very nice instructions that make the conversion really easy. When I did my obd0-1 conversion I got rywire and I didnt know crap about wiring. It took me a couple hours to get familiar with the wires and to know exactly what to do. I did the conversion again in my girl friends crx and it took me about an hour. But to do it right, if I were you, I would go out and get solder, soldering gun, heat shrink tube, and some wire loom. It will look 100% times better if you do it right and get the wires in wire loom to make it look like its supose to be there.

And if you want to do a b20 swap you could just put another 600 or so into it and do CR-Vtec. Its the crv engine with a b16 or b18 vtec head on it. Pretty simple. Did an ls-vtec, which is basicly the same swap, as my first engine swap. Just need to do your home work on it and get the right tools and your golden.

do you still have links to write-ups you were looking at for your ls-vtec/crvtec?
