So i have this engine and i want to make it haul the heavy ass hilux along well. So i have thought a bottom end rebuild and boring the cylinders to 92mm from 89(anyone no wot oversize this is?) to get 2200cc and new pistons with cromely rings. Up top a good port and polish with bigger valves and double valve springs with mid range billet cams (2000-6000rpm power). Custom exhaust and inlet manifold with twin 45s on one end and 2" or 2.5" exhaust at the other. I already have TAI (transmittor asstited ingintion system) to go on. I not going to lighten the flywheel cause it is a cast iron one and i don't want to have to rev the hell out of it to get it moving. Is there anything i have missed that i could do along the way?
