COBB Tuning upgrades the GTR turbos

The testing phases of our upgraded turbos for the Nissan R35 GTR has begun.

GTR Turbo and Manifold

We have upgraded the compressor wheel to be 8.5mm larger than original while the turbine wheel is an impressive 10mm larger than stock. To fit these huge wheels, we have machined the stock turbos and are using custom sleeves and bearings. We are hoping, with help from the COBB Tuning AccessPORT, that we will be able to see power increases in excess of 150 HP with this 44 lb/min. wheel.

GTR Turbo 3

As you can see, the new wheel is much larger than the original.

More information will be posted as it becomes available.

Stay tuned.

  1. Jason,

    While I understand the appeal of an upgraded turbo + tune from a single source, rest assured that the AccessPORT will complement any upgraded turbo kit and get the maximum power available from the kit while providing exceptional driveability.
