I have a B16a2 with 2 bad pistons and I have a freshly built B18c1. I have a question I want to use my B16's Greddy extreme timing belt on the GSR. What all will I have to swap over to make it work(i.e b16 or b8 water pump and will my B16 oil pump be sufficent or do I need to have the GSR or Type R oil pump).
