need info on swapping b18a1 to 91 crx si

im swapping b18a1 into 91 crx si and i need to know what wiring mods need to be done, is the crx obd-0 or 1??
any help would be appreciated

you need a mount kit and shift linkages.

extend the TPS and EACV.

OBD0.

Use the PR4.

im a little new to all of the wiring aspects of the motors, if you could explain the pr4 to me?

the PR4 is the 90-91 Integra OBD0 ECU. Use it with the engine as it will work properly with the PM6 (Civic/CRX Si ECU) but it will run very rich and wont be tuned correctly for use with b18a1.

ok, i have the ecu, and wiring harness for the engine, but its from a 93 ls, is that usable
also which harness would i use??
thanks again for the help

do you recommend finding the ecu from a 90-91 b18a1 and using it with a modified crx harness so all of the obd's match up, if that would work??

and does anyone know where i can get some axles that will fit this swap, i checked on raxles.com but im wondering if there are any stock ones that would work

just buy axles from autozone or something, they are lifetime guarantee and about $60 per side. (91 acura integra LS)

I would suggest that you take the b18a1 wiring harness off the engine and use your stock crx si one. it will connect right up to everything.

Find and use a 90-91 OBD0 PR4 ECU. If you cannot find one, message me, i have a couple laying around. we can work out a trade or something.

cool i'll keep that in mind,
this may sound like a dumb question but i dont have the crx yet im buying it from a friend, this swap was originally intended for a 95 civic,
but the crx tranny is cable right, and if so are there any other cable trannies with better gear ratios than the ls,that will fit the engine?

The B16 and B17 transmission.

what year/s was the b16 tranny cable?
