Um if he has a I4 and beat you I can almost guarantee he is running turbo or NOS, or both
I am able to keep up with almost all stock pickups. as for light trucks the only ones that can beat me are the dodge dakota V8s...I wonder why?
I guess start with chip, intake, headers, full exhgaust high flow cats, aluminum radiator and electric fans, REAR GEARS and better tires. perhaps some lightweight
rims and good race tires. A slight drop and some
suspension tuning, oh ladder bars, supercharger, NOS, twin turbos, rebuild teh bottom end of course for the last 3, port/polish heads. install manual steering and disconnect the A/C. Get some performance intake from Kenny Brown (the guy with the 600 hp 3.8 mustang)
There is a LONG list of cra you can do for our trucks if you have money.
remove non essential equipment from truck (spare tire, passenger seat, jack, headlights, tailgate, swap drivers seat with recaro buckets. ditch the bulky dash, replace with a single piece of bent aluminnum for weight and appearance.
must I go on?
