The Big Wang is here! These Airfoils can produce incredible levels of down-force without killing top speed. Exactly what racers are after. Extruded aluminum wings were developed, patented, and built for a prototype project. Nine Lives Racing takes the raw material and makes them readily available to the public as a working part. It's the best wing in its class. 15.2:1 lift-to-drag ratio*. Nothing else compares. A built-in gurney flap relief allows for down-force adjustments in seconds.
An LS swap in a Nissan provides numerous benefits, including increased power and torque, improved tunability, and a greater range of aftermarket support. LS engines offer a great balance of performance and affordability, with modern technology enhancing power and drivability.
Choosing the right motor mounts involves selecting mounts specifically designed for your Nissan model and LS engine configuration. These mounts ensure secure and precise placement of the engine, accommodating any modifications needed for a seamless fit.
PCM tuning is crucial as it customizes the engine control unit to optimize the performance of the LS engine and transmission. This tuning adjusts fuel maps, ignition timing, and other parameters to ensure the engine runs efficiently and reliably within the Nissan chassis.
PSI Conversion’s standalone wiring harnesses are designed to be versatile and can fit a range of Nissan models. However, it’s important to confirm compatibility with your specific vehicle and engine setup to ensure seamless integration and optimal performance.
