Gregs Nissan HR32 Skyline GT-S4 AWD RB20DET Turbo Custom GTR FMIC

Notice the intake AirBox is not standard with a much larger outlet with the Mass Airflow Meter mounted in the side of it. This was originally done to balance out the fuel flow for the Mazda RX7 Fuel Injectors and worked perfectly to be able to drive to be Dyno tuned when the whole system was optimised by DR. Drift. Does not show the extended entrance to the AirBox that ducted cold air via much larger piping from under front bumper opening on passenger side. AirBox was fitted with High performance foam filter.
