whats the budget? nitrous is the best bang for the buck....i prefer turbo...for $2500 you can get a bolt on turbo kit then just add 550cc injectors, a walbro 255 and a tune and you got a 12 second car. i ran 12.50's with a stock gsr, drag gen III, 550's, walbro 255, and scotty crome tune on 7psi in a vx hatch that weighed 2250lbs w/ me in it..also ran 12.20's with stock gsr, peakboost topmount, 550's, walbro 255, and a jkobd basemap on 10psi in a 93 dx 4 door that wieghed 2650lbs w/ me in it.
