Well i am about to purchase a 91 hatch with a 1.5 sohc motor with the dual point injection. I know of a place where there is a 89 or 90 Integra with a dohc motor in it. I beleive its a ZC. I want to put the dohc head on my sohc block. Now if it will work is there any power gains expected? Or higher compression. And also the Integra is a automatic, but the hatch is a 4spd. Are the ecus different or do i just need the wiring harness. Im really tring to get away from the dual point and get a throttle body and intake and injectors. Oh and is 500 bucks for this civic hatch to much.
