When it comes to the overall performance of your custom vehicle, nothing comes close to an upgrade like a supercharger.
With the new look, sound, and an extra 30- to 35-percent gain in horsepower, it's one engine mod that will get you noticed. Superchargers are beltdriven from the crank, delivering more torque and horsepower from idle to redline.
There are many choices out there, but when it comes to Toyota performance LC Engineering offers positive-displacement Roots-type superchargers for most Toyota applications. This kit is designed and developed extensively for the popular Toyota 2RZ that we are working on here. This original TRD supercharger kit manufactured by Alpine comes with all the hardware and electronics you need to complete this build. Follow along and see the steps we took to install this supercharger.
