SouthSide Performance have been tackling the GT-Rs throttle bodies in a quest for a larger opening and a more responsive drive. SouthSide aren’t the first to go down this path as even Nissan has recognized that the base model GT-R could do with some improvement on the throttle body side of things when refining the SpecV’s version. These should be quite a bit larger though.

These billet items should be released soon as they’re currently in the final testing phases.
