i cant seem to find any aftermarket turbos for a 6.5. can i use a gm8 on a 94? it has a gm4 on it now. will the gm8 give it more power? im trying to make as much power as i can out of this motor, but theres not a big aftermarket for it. i can bend my own pipe and make exaust and stuff, but i cant find a nice big turbo. i plan to build an intercooler into it aswell. any help would be awsome, thanks.
