i am looking for a perfect swap meaning that i want the wires and everything to match with no mods. is this possible. have a 93 integra gs with the b18a1 inside, i want to put in a vtec motor. I found the b16a with the ecu and trans for a good price, but i wonder if it will be an exact fit or not. or if the b17a1 would be an exact fit, or if either one would fit at all.thanx.
