currently i have 1-5/8" hooker unequal length headers, x-pipe, flomasters, bbk adj fuel pressure regulator, bbk fenderwell intake, underdrive pullys, msd coil and 6al w/fms 9mm wires. the car has 68k on the odometer and i bought it from the second owner who put the mods on the car within the year he owned it, what should i get next?? i was thinking about throttle body and mass air, getting rid of the flowmasters for borla, and stiffining the chassis alittle. as far as supercharging goes with the stock internals(hypertectic pistons) will the engine take it with the miles or at all?? gears? cams? i would really appreciate anything you can throw out there. thanks!!
