@rafay...thats all like bullshit...a bigger carb jet will give some difference...but not much...its not all about extra fuel. btw i dont remember correctly if the jets in a altos carb can be changed...i dont think they can be...so ull have to get a bigger carb.
and about n2o...not many alterations are required to fit nitrous in a stock car...its better if uve got headers and a free flowing exhaust system...ne ways...i used nitrous in my stock vitz.
@nadeem. what are u trying to say? what the hell is exhaust back turbo?
see man...what u need to do is do some research..look around what a turbo is, what it does, how is it used, how is installed, how is it tuned.
and yea ofcourse the points Kiani mentioned are ovbious.
about point number 4...ive got the pefect guy for this...same guy who supercharged zeeshans khyber...if u are serious then giv him a call...his name is Tariq...and his number is 0321-243-3269. call him up and tell him Asad gave u his number...peace
