Since the motor is currently out of the car, don't ask me to elaborate on what our times/BHP is at the moment, cuz there aren't any, but this is the setup:
HKS T51R Single Turbo
HKS 60mm GT wastegate
HKS 3" downpipe
that is the standard upgrade for the single, but along with that we are in the process of completely working the motor, with all new HKS goodies. The fuel system is being handled by HKS Fuel Mgmt system, with 1000 CC injectors, SS braided lines, 1500 HP extrenal pump w/ multi filter setup, huge Race Spec FMIC etc etc.
Now, I didn't read above - but what are you asking about the single?
