    Hey guys. Got a friend who just bought a Mighty Max with a 4g64. Planning on helping him make it DOHC and turbo. I have a 4g61 head that came from a "4g63" from a shady place i shouldnt have bought from haha. I know it will bolt up, but not sure what T Belt i need. Same as a 63 head swap i assume? Just want to double check and see if anyone has done this who has any advice. I figure the 61 head would bump up compression, which would be good, at least for now. Anyone know what the compression would be? Im going to be going EVO3 whenever i get around to finishing mine, and then we might put the little stocker on the MM. So i feel maybe i should have him get an EPROM ecu now rather then later. Can this be done with some simple repinning? Planning on using my stock turbo 63 cams as i put BC 272s in my fresh 6 bolt. Anything else i should be aware of or plan for before tearing into this? Thanks guys!
