There are so many 1JZ owners with faulty hydraulic water pumps that we put together a simply package for conversion.
This is a genuine 2JZGTE water pump from Toyota and is designed to eliminate the hydrofan pump on a 1JZGTE engine.
You will receive a complete water pump with rear housing and also includes two new o-rings for the coolant bypass tube directly above the thermostat.
This is just for the water pump assembly and assumes you already have the correct pulley. Not to fear though, if you are just doing the conversion for the first time you will need the correct pulley assembly which mates to your 1JZ engine and the new water pump. We have those available, so simply select this option in the drop down menu!
We have shipped these conversion kits all over the world and they work on all 1JZ engines.
