Mitsu Motor Rebuild?

Hey guys, I might be acquiring an old mitsu mighty max but the enging needs rebuilt but i'm getting that truck and another mitsu for 150 bucks US!!! So I think it's good enough for another project considerin' my s-10 is bagged and such, but where can i find a rebuild kit for a mitsu? do they make a master rebuild with a new head and shit too? also, any performance shit as well??

Thankx ya'll,Chris
