^ a starlet can achieve 300+ , and has been proven a good few times. also should mention that your forging the wrong block if you want 400 out your car. 5e block can cope NO problems. its blatantly obvious a gt4 will have far better traction providing the fact its AWD... its gona beat a glanza no problem being moderately tuned it would manage 300bhp no problem. matching a gt4 against a glanza is not much of a comparison the gt4 would always win.
