i know people who have had luck with it, but that was after they blew the first block running 10 to 15 psi and stock sleeves. we're talking cracked sleeves, holes out of both ends of the block from rods shooting through, damaged chambers on the head, damaged turbo housings! I would seriously consider resleeving the CRV block or using the LS block right of the bat if money is an issue. once the block is resleeved than have at it 20psi if you want!!
