Help! Need swap information.

Ok heres the deal. I have a B16A SiR 1 swap already but I wrecked my 90 RS the other day and now I need another car cause Im just using that one for parts. I found a 92LS but the problem is that the car is OBD 1 and my swap isnt. I just wanna know how hard it will be to put the swap in this car. I pretty much can reuse everything on the 90 except all the right side body panels and im not sure about the one axle. Would I have to put the wiring harness from the 90 in the 92? Can i reuse the 92 harness? Should I just look for 90-91? Any help would be good. Thanks

Please read the engine swap guide on the teg tips page. It has all of the information you need.
