wondering about motor swap idea
Met a guy over the weekend who is willing to selling me his 1994 Integra LS block, head, intake manifold w/injectors plus a gsr intake manifold and CRV harness w/sensors for $400. Since I was considering getting a zc for my 90 CRX Si shell, this appealed to me a bit seeing as it is about the same price. The LS longblock needs a trans as it doesn't come with one so I was thinking about getting a 92-93 GSR cable trans. I will also need to get an LS distributor and throttle body plus mounts to make the swap possible. My question is that I was told since the longblock doesn't come with any sensors I could use the sensors from the CRV b20 and use the CRX Si harness. Is this true about compatability? I'm not sure if OBD1 sesors on LS and b20 are the same. What do you guys think?

Ok, I've done a little research now and need to be sure about a few more things.
1. a 1990 CRX Si is an OBD0, and i've heard that the OBD0 integra ls pr4 ecu will plug into the CRX Si harness. Is this correct?
2. If using the CRX Si engine harness, how many of the sensors will plug into the longblock and which ones will not?
3. I've also read that I should run a obd0 90-93 integra distributor.
I guess in short I am wanting to know what is involved and what I will need to drop the 94 LS longblock w/90-93 integra cable trans into my 90 CRX Si.

ok im doing a ls swap in my crx in about a month while I get everything together
First of all you want to use a pr4 ecu from a 90-91 integra ls.
second all the sensors will hook up to your si harness but one the crank senor. alos you might have to redirect a switch to the thermosat housing
third you need a 90-91 integra dist. and injectors. this is becuase the integra from 92-93 is obd1 and not obd0
fourth you would want to use a cable trany from a 90-91 integra also because i dont think they made gsr cable trany's but dont quote me on that one.
Fifth your going to need the rear engine bracket from a 90-93 integra
pm me for anything else or aim me = FATALxERRORx5
