NST 1GR TRD SC Kit NST 1GR TRD SC Kit NST 1GR TRD SC Kit

The 178mm NST Overdrive Kit designed for the Toyota 1GR easily replaces the TRD Supercharger's crank pulley insert, idler, and tensioner pulleys. In comparison to the TRD crank pulley insert, the 178mm NST kit increases the rotational speed of the TRD SC to increase boost levels from the stock 6.5 psi to roughly 8.0 psi.
