The Porsche 944  KKK K26 turbocharger came limited from the factory.  They come limited b/c of the compressor housing not being able to take a larger compressor wheel.  BNR offers 3 stages of turbocharger upgrades.  All upgrades come with upgraded compressor housings and custom machined seal plates.  These upgrades are bolt up and come with a 1 year warranty.  Rebuildable turbocharger core required.

BNR stage 1

The BNR Stage 1 consists of an upgraded compressor wheel and compressor housing.  The factory turbine wheel is clipped to reduce back pressure.  It also helps stabilize boost control and rotating assembly RPM.  The stage 1 is rated for 300-330 RWHP in a properly tuned car.  The rotating assembly is balanced and blueprinted.  Turbo response is near to stock.  The turbocharger upgrade is remanufactured and given a 1 year warranty through BNR Supercars.
