Ok, I'm a Honda Guru but when it comes to this type of single cam shit. I just dont know, and kinda don't care. But now I have to care. Im doing this mini-me swap for someone on there DX bottom end, but I busted a piston trying to pop it out the top, it happens. All that is available right now is a 95 dx block that a friend has at another place, I believe the PO3 pist. and PM3 are identical but want to double check with someone else before I go pick it up. Hit me up on this fellow Gurus!
