If you want megga horsepower from a 3sgte engine, I wouldnt over bore it at all, you`ll only make it weaker...IIRC the max recommended bore increase is only about 2mm anyway so its hardly worth it, if you want a bigger displacement then get a stroker kit, but they arnt held in much regard either. you dont need to have bigger displacement to unleash the power available from a 3sgte, just a very well mapped engine, a BFO turbo ,huge injectors and deep pockets.
