I came across mini-me setups for crx si's but only on the 2nd gens. I was wondering is it possible to do this on a 1st gen? If so what is the difference in swaps if any? I do know this the 87 is 1500cc ,the 88-91's are 1600cc and the heads come off of 1600cc engines but i always hear of b18 heads on b20 blocks so is this possible? Given the fact that their all d series engines should'nt they all match up?
