The BNR Stage 4 is the world record holder for ANY S4 or S5 turbocharger upgrades for most power ever recorded on a dyno! It made 402.7 SAE RWHP and kept that power all the way through the power band. The boost went from 18 down to 15 psi and the car generated that HP at 15 psi. So why go to another manifold when you can throw down a tremendous amount of power with a sleeper of a turbo! The turbo upgrade consists of a P trim turbine wheel, 60-1 compressor wheel, 35mm wastegate port, and the trick is in the porting of the turbine housing. A 360 thrust bearing is standard on the stage 4. The turbocharger is common, but we specialize on getting out what you put in! The turbine housing is opened up tremendously therefore decreasing backpressure. Not only did we make 400+RWHP, we did it using a factory style internal wastegate! This turbocharger upgrade is bolt up and no fabrication is required.
