This is the SteamSpeed STX 67 Turbocharger designed to be a direct replacement as well as an upgrade for the N55 inline 6 cylinder motors with the TwinPower Direct Injection. SteamSpeed made this turbo to be a stock location replacement which means that not only will it appear stock, and it can also utilize exhausts and intercooler components that your factory turbochargers had used.
Additionally, SteamSpeed makes their turbochargers using all brand new components which means that there are no core deposits and you do not have to return your factory turbocharger. This is a brand new turbocharger that features a compressor wheel that is crafted from 5-axis CNC milled billet aluminum and flow up to 30% more than the stock turbocharger. The turbine wheel is 47mm/53mm with a compressor wheel option of 45.8mm/67mm.
The result is +75-90 WHP over stock.
Note that this upgrade is designed for stock fitment and replaces the center cartridge and compressor housing. This means you will reuse the stock turbine housing, actuator, as well as the blow-off valve. The SteamSpeed CHRA and compressor housing will fit directly into your stock turbine housing.
