Oh I see said the blind man....Well in that case Turbo or supercharger would be best bet unless your going to do internals. I would swap it if you come across a cheap B series block. I actually have my old B20 block being machined and ported now. Need to buy a rex to throw it in. LOL I had a 87 Crx Si with a blown 1.5 but we had a nasty storm 2 years ago and a 30 ft Pine tree decided to test the durability of lil rex and he lost. Is that a little more profesional Han style advice for ya.
