its 90 si hatch. not a coupe, it has a da16a6 in it. my brother got the car some years back. he blew a hole in the block somehow and then went off to the navy. so i just need to get it running so i can move it to vegas. so if its possible to use a non si block then ill have it swapped in and get it going. but i dont know much about these hondas, so im asking for anyones help who knows.
