Accufab has recently developed a SWAP program for Nissan GT-R throttle body customers. They manufacture an aftermarket throttle body set for the Nissan GT-R. Each throttle body is CNC machined from top quality billet aluminum, no cheap cast product like the OEM set! Then, they polish each piece to a brilliant, mirror like finish.
All assembly component parts, from the shaft, butterfly, seals and bearings are all the best the industry has to offer. Each has a stainless steel split shaft using strong & reliable ARP screws in each throttle body shaft. More specifically, they use a 65mm blade with a throttle body inlet opening, approximately, 73mm OD. The bolt pattern is exactly the same as the stock unit.
