I think alot of people have asked this question, but fuck it I'll ask again. I have a rex that I buying a SIR1 complete swap and I also have a B18c5 long block laying around to. Well I doing the SIR swap because it is easier to do. But I was wondering how much of a wiring hassle would it be if I throw in the B18c5. I know I have to use the obd0 distributor also the Crank pistioning sensor will not be used and the injectors off the SIR will have to be used. I plan to used the SIR tranny as well. To that point is all the research I have done, so if anyone knows the info or have seen some site or it done, reply.
