the GTR is so well developed that it should be maintained standard on the outside as it gives the best balance..many owner would revert to the old rims for track days as it gives better performance..however the RB26 at stock gives about 310bhp which is considered very mild..throw in an ecu and let the engine breath with 1.2 bar boost from a mild 0.8bar, you would see and easy 420bhp at the wheels..my 33 has gotten a little more than that and pushing 680bhp at the wheels with a 2.8 litre kit by JUN and some turbo upgrades..however it is a little wild..my 34 is maintained at 500bhp as it is the best power setup for road use..
