I was probably going to use something like that. I may end up buying stuff from mitsubishi. I may not start my build til the end of the year so I won't have any definites on availability til then. Now I know alot of 4d56 stuff is the same. It's possible we could get parts through there. Personally I don't intend to replace pistons or sleeves unless I have to. Just the bearings, seals and such internally. I can get bearings from Clevite. I've got them in my 94 and theyre used in NASCAR so I can assume they'll hold up just fine.
