@tmkhan: go fer STAGE 1 mods, a frnd ov mine got it fer like round 30k fer his nissan sunny frem RPM MOTORSPORTS. it cost him like 30k because the car had SENSORS in the engine bay and if sumthng had gome wrong, the car wud have gone malfunctioned. Stage 1 mods wud give u round 50+hp increase. Exhaust, Spark Plugs, Piping, Ground Wires, Air Intake all go into Stage 1 Mods.
