car balance is most important thing, use of nos makes car unbalanced, takes it out from braking power, handling power, its like motorcycle acceleration instead of car, and safty decreases on bikes.
most of pwlers who used to enjoy acceleration are going for bigger displacement engines after trying out lightweight cars because in the end ppl realize from their own experience, other things matters apart from Horsepower.
you need to have a well balanced car if you want a smaller car to perform like a heavier model. Most mechanical eqt has to be adjusted when you change horsepower.
4agze supercharged engines are far n few now. that was grt engine in late 80's / early 90's.
now in other countries ppl using them have already modified them one way or other.
in this post the modified 7a with 20v head maybe a good choice as you can find parts for both in peshawer, but again setup has its pros and cons.
