GReddy RB26 (Single Throttle) Surge Tank Kit





GReddy Intake Plenums are designed to maximize performance in highly tuned engines. 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. The kit features a large 90mm throttle-body and a 4.1L surge tank, that is 121% larger than the OEM piece. 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. Between each connection are carefully designed and manufactured sealing rings. The CNC machined primary runners are sized for optimal efficiency. The kit comes anodized to provide a durable, scratch and rust resistant finish.

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
