I can already see the first problem, the intake manifold cannot bolt onto the GSR. The GSR uses a different pattern then then other B series. GSR can only use GSR IM or an aftermarket IM. Exhaust and dizzy should work tho. You could swap the head over tho. The B16 head will work but then you lose the B18 cams. You should look into a Skunk 2 IM for the GSR.
