The Magnuson MP90 Supercharger system for the FJ Cruiser’s 1GR-FE 4.0L forcefeeds the V6 with 5-6psi of boost for a total output of 305hp and 335lb-ft at the crank. This roots type blower gives the FJ instantaneous response and torque on demand across the rev-band with none of the lag of a turbo. Furthermore, the bypass valve system virtually eliminates parasitic loss when cruising, preserving your MPG. Mash the go pedal, and you’re greeted with a tsunami of pin-you-to-your-seat torque.

The MP90 boasts great underhood appeal thanks to fit and finish on par with factory equipment. Engineered to keep heat soak at bay, this system features a large integrated liquid to air intercooler chilled by a front mounted heat exchanger, fed by an electric water pump. The robust cooling system ensures consistent performance from startup to shutdown, whether that’s a hard day at work or a day at Glamis. Engineered to offer Toyota-level reliability, this system’s all in one design integrates the intake manifold, supercharger and intercooler eliminates potential leak points. The blower’s maintenance free design comes pre-filled and sealed, so there’s no oil to fill or change, ever.

A calibration with handheld installer is included. Our engineers have tailored this calibration for excellent below the curve power and torque you can use in the real world, as well as peak hp. Installing this 50-state legal direct-bolt on is straightforward – a pro can do it in about a day, an enthusiast can in a weekend. Easily reverts to stock if needed.
