don't go with a 200 shot unless the block is sleeved. stock honda sleeves at stock bore will handle ~300whp. so a 200shot at any comp. ratio is no good(unless the block has aftermarket sleeves) 12.5:1 comp ratio is on the high side for the street. aim for 12-12.3:1 comp. you'll make all the power you need in a crx all motor ls/vtec.
