so far on my belltech lowered (4/5) S-10 i have put on a gibson exhaust, msd ignition with blaster coil, ngk platinum spark plugs, flex-a-lite fan, jba headers, k&n gen. 2 intake, jet chip, jet shift improvemnet kit, tb spacers, and underdrive pulleys. i have a vortec 4.3 V-6 engine. i can't put on a mass air flow sensor since mines all one unit and superchargin' is too expensive for me at the moment. i dont want to ruin my engine with nitrous. any other mods anyone else can think of while being reasonable?...thanks for reading.
