Ive read bout the mini-me swap myself but have a friend who had a question bout doin it to his dx crx but i wasnt sure if u could use any 1.5 cus his engine is 8 valve which the pistons only have 2 indents so it the other 2 valves gonna clear, will he be able to drop a vtec head on it with no problems? THANX
