“R/T Tuning is proud to offer upgraded stock location replacement turbos for the Infiniti VR30 motor. These upgraded turbos still retain the stock housings which will allow you to use your existing exhaust and intake configuration. These turbos flow about 30% more without sacrificing spool response with their custom machined billet wheels. These turbos are available for both red Sport and non red sport models. The red sport turbos still retain the OEM functionality of the turbo speed sensor.
