Integra LS

What's involved in replacing a '90 Integra LS B18A engine with one from a later model (94+) ? I have a tired B18A with the oil pump light occasionaly coming on. Also, can I replace the stock pump with a GS-R pump ?

Thanks

you can do that if you want. You will just have to use your B18A distributor and maybe some other parts from it...
