My 88 CRX dx broke its timing belt yesterday.(ouch) My friend says that I could probably pull off an EX Vtec Head swap for 500 or 600$. I need to know what is needed, and a cost estimate. I was also thinking that I would just convert to Si(I know I have to convert to mpfi). I really don't know what I should do. This is my daily driver and I would like to get her back on her feet as soon as possible; and of course a little h/p wouldn't hurt anything. So please help!
