Throttle-body hose diameter φ100mm, internal butterfly φ90mm, with low-profile throttle shaft Tuned internal velocity stacks on each runner for increased efficiencyĬNC machined inlet runners L90㎜, Pipe Size φ58-45 (tapered) SURGE TANK / 6 CNC PRIMARY RUNNERS / THROTTLE BODYĬollector Surge Tank Size is 4.1l(VS Normal121%) Skyline (BNR32 / BCNR33 / BNR34) GT-R Single Throttle Kit includes: Testing on a high-powered 958hp/663ft-lb R32 GT-R showed a substantial increased in power throughout the RPM range to 1023hp/697ft-lbs OEM Throttle position sensor and OEM AAC valve are compatiable.RB26 Single throttle plenum → Design for stand alone ECU.The kit comes anodized to provide a durable, scratch and rust resistant finish. The CNC machined primary runners are sized for optimal efficiency. Between each connection are carefully designed and manufactured sealing rings. For extra rigidity during high boost applications, it uses thick 3mm formed metal tank that is welded to a precision machined, grooved base plate, with six individual, internal velocity-stacks. The kit features a large 90mm throttle-body and a 4.1L surge tank, that is 121% larger then the OEM piece. The single throttle body surge tank conversion for the (R32 / R33 / R34) RB26 puts an emphasis on a balance of high power and mid-range torque. GReddy Intake Plenums are designed to maximize performance in highly tuned engines.
