The Rotrex is the ONLY centrifugal Supercharger that is used as OEM factory fitment on a production car ‘ the world speed record holder Koenigsegg CCX.

Developed and manufactured in house, the Toyota 1GR-Fe installation is an exciting OEM style kit.

Designed to suit an internally standard engine, the intercooled Bullet/Rotrex kit reliably increases power to over 200 kws at the wheels! This is a gain of over 50% and is achieved with only 8psi of boost pressure. The power delivery from the Rotrex Supercharger is extremely smooth and feels like a factory installation. With unmatched boost response and silent operation, it really does turn the 4L Toyota into an exciting well balanced sports truck!

    Transformation is incredible!!! I bought this kit to fit to my V6 4.0 2015 (8th gen) Hilux SR5 automatic. Kit is well made & I was very happy with the quality & workmanship of all the components. I had the kit professionally installed by my mechanic here in Melbourne, complete with the intercooler & performance exhaust. It all fitted up as it should with no issues (well done Bullet)! Kit has been on the car now for around 6 years without any problems. The power comes on strong & smooth & I am very happy with the result. The engine was dyno’d after the install & produces 250rwkw & around 480nm of torque. Highway towing is a breeze & the power/ torque curve when sitting on 100kph is perfect. I recommend this upgrade to anyone considering. This kit is the best upgrade I have done to my Hilux. After driving this car with forced induction, I don’t think I’ll ever own an normally aspirated car again!!!
