Holset Wastegate Controller
When swapping a wastegated Holset turbocharger, you'll need this controller/actuator to be able to set the maximum boost level for your application. These directly replace the pressure referenced "pot" assembly that is bolted onto these turbochargers. Those are usually set at 20+ psi and are not adjustable down from the base pressure.
Please verify your housing arm style before purchasing as there are two styles available. Both the genuine Holset and knockoff copy housings can come in both configurations! The waste-gate arm (on the turbo) is either Vertical or Horizontal when in the CLOSED position. Order accordingly.
Compatible with Super 54, WH1C, HX35W, HX40W, HX40WII
*Downpipe adapters and full installation kits are available in our other listings to complete your project!
