T51R Modification - Available at AGP; But What is It?

26th Sep 2019

Back in the early tuner days of turbos and wastegates and blow off valves and boost controllers and VPCs and Super AFCs there was a turbo line from HKS, called the T51R.  HKS used Garrett GT Ball Bearing technology and developed their own end housings to promote their elite product line of turbos, and one of those features was a compressor housing that had a sound like no other.  Call it a whine, call it a whistle, call it a jet engine taking off, the T51R certainly was not a stealth.

Fast forward a generation or two, and people still want that unique sound and we are able to provide that on modern technology turbos.  We call it the T51R Modifcation or T51R Mod.  We are currently offering the T51R Mod as a $350 option to all new Borg Warner S300SX-E turbos.  Please allow approx 5 business days after the order as each Mod is made to order.

The process begins with completely machining the inlet away on the compressor housing in our CNC, and pressing in a billet slug to fill in all the dead space.  The housing is then back on the CNC to be re-contoured for your specific wheel profile, ported shroud slot groove machined, and then tapered all the way to the outer inlet.  The result is a beautiful machined masterpiece and the sound will definitely get you the attention you're after.
