ok,b18 swap going into a 90 crx si.

we are having to use the b18 wiring harness and repin some wires and run a few extra wires,easy enough.

question i have involves the dist and the injectors. we are using a 91 integra ecu,is that plug in play,do we have to do any repinning on the ecu harness?

what dist can we use,from what year teg?and id assume the injectors would have to be from the same year also?

will the teg axles work on the si?just bolt them in?one has a bs,does that matter?my freind said he could knock off the abs ring.

if you have any more info on this swap id be more than happy to listen,ive searched but only found things on the b16 going into the crx,thanx alot.

good luck w the b18 harness, use your si harness instead its pretty much all plug and play. 90-91 ls ecu will also plug in but i would use the crx si ecu (my b18 runs much better w the crx si ecu). the only thing you need is an obd0 ls distributor and that will plug right into the si harness.
the only hard part for me was getting all the vacuum lines in the right places and getting it idling like its supposed to.
pm me if u need the vacuum diagram of the lines

 

1. yes the 91 integra ecu is plug and play, with repining of very few wires if using the Si harness....youll need to make these connections on the block too.

2. You can use any obd0 b series distributor.

3. The fuel injectors can be really any kind that are a peak and hold and 240 cc, all 88-91 honda are 240 cc.

4. The 90-91 teg axles will work. Youll have to remove the dust ring from the knuckle on the rotor assembly.
