The PHR Thermostat Delete provides a simple solution for those looking to completely remove their thermostat from the 2JZGTE.
If you simply remove the thermostat, there is no longer a valve to close the bypass off and water can freely run back to the waterpump without entering the radiator. This kit provides a thermostat replacement ring and radiator bypass tube that is closed on one end to keep flow through the radiator at all times.
