I have a D16Y4 engine, 195Kkms and the gearbox is kinda seeing its end (chipped tooth on first and second gears) and my engine isnt at its best. I was wondering if its possible to fit a B16B vtec head (with B16B ecu and i add on the soilitoid) and a b16b gearbox (with b16b shifter) because it has better gear ratios than a ek1 gerbox.

If they do fit, what else do i need?
