Want to know if putting this SOHC VTEC head on my 91 CRX Si is gonna cost me more than just putting a b16a in it? Also,if you guys(and girls) say it is better for me to do this mini me swap, where is a good place to buy some pistons? I have read 4-5 web pages that tell me I can choose from my stock ones or some out of a 5th gen civic EX.I don't want the compression ratio too high.Would like to have it between 9.5:1- 10.5:1.And it is gonna be sprayed with about 100-150 shot.Let me know.Thanks you.(by the way,I already have a d block and the VTEC head so you guys help me out)
