simon its cause the car has a different power band range
your comparing a car to a 220 bhp frst,,,,,,,,,,, there 2 different cars
its like me comparing it to a cossie or a v6/v8 ect
the nova's performance is unbelivable when you consider its just a cavalier engine,,,,,,,,,,,, thats it nothing else but a n/a 2.0 family 4 door saloon engine
