1.) I have a 93 GSR complete engine. I know it will fit into a 95 gsr but will the orig. ECU from the 95 GSR work on the 93 manifold? If not, which ECU is best (b17, b16, ITR)? BUT Will the 93 GSR ECU or EQUIV. clip into the harness from the 95 because they are BOTH OBD1? Should I just use the 93 one? 2.)What if I were to put a b18c head on the b17 block and use the b18c manifold with the 95 ECU? Does stoke matter to the ECU? Is the orig. B17 manifold better than the 95 GSR mani??Thanks. p.s. Is it OK to switch the Crank journal CAPS or ROd caps with ones from another block??Will it give the plastiguage a taper?
