BNR Supercars has developed a new T04 turbocharger that performs really well for the price! Biggest bang for the buck for power and response for a medium sized turbocharger! This unit will flow 75 lb/min and has the response of a GT35R!

There are 2 turbine housing options: .81 a/r and .96 a/r. If your car is Rotary powered a .96 is suggested for this turbocharger. The turbine housings have a 3” v band outlet which makes it a direct bolt on for many using Garrett T4 turbochargers on their cars! You also have the option of a water cooled bearing housing and a non-water cooled bearing housing. All turbochargers have high performance thrust bearings to ensure a long life with higher boost applications!
