GReddy Billet Air Intake Surge Tank Kit (Single Throttle) - RB26DETT R32 R33 R34

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 then 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 increase in power throughout the RPM range to 1023hp/697ft-lbs
