You're car is fitted with a MPI air filter box -so i'm assuming it's an MPI.... the 'bob' in the dexcraft ad is for an SPI engine!
When you are old enough to drive this car on the public highway (assuming at some stage you pass a driving test) you will find out it's not how much power a car has but a combination of driving skill & how much power you can put down that makes the difference. You could have a 400bhp engine but if the tyres are cheapo budget items you'll only end up in a ditch, same goes for the suspension -how knackered are the suspension bushes/shock absorbers. Also how healthy is the engine? when did it last have any attention? -oil, plugs, belts, shims etc.
Forget the HP bull-crap talked about by the boy racers & their magical bolt on gizmos & concentrate on getting everything up to scratch. People like their little Fiats not because they have lots of horse power but because they can punch above their weight & put larger more powerful & expensive cars to shame.
