the st24s handle really well for a std barge imo mate! it wont be like driving the car in your sig obv but still!

the engines are 170bhp, the same as the st24, but the inlet, throttle body, exhuasts, cams and ecu from the st200 with bolt straight on (same engine, just different spec, like the 1.8 zetecs). as said, with that lot and a few aftermarket goodies you'll be knocking on the door of 220bhp no hassle.
