My buddy has a mid 90s Kinetic TFR that he wants me to "beef up" a little. I figured that slapping an old Polini country exhaust I have on there and drilling some holes in the air box should be a step in the right direction. Does any one know what number the factory jet in a 90s kinetic is? I'm thinking that with the new pipe and more air I should bump up the jet about 4 sizes. Does that sound about right or am I way off?
