Eliminate boost creep and spike commonly found with the GReddy TD06SH 20G turbocharger kit. The Greddy kit is awesome in its completeness, but why they offer such a powerful turbo with a small internal wastegate we will never understand. The ATS Racing external wastegate conversion kit includes machined (not cast) turbo adaptor with wastegate feed and flange, Tial 38mm external wastegate, wastegate dump tube with flange, and all necessary hardware. You have several options on eliminating the original internal wastegate: Removing the boost reference line from the Greddy actuator is enough to keep it shut. Or you can send us your exhaust housing and we will weld it shut for free.
