PHR Lower Water Neck Rotator For Big Turbo


PHR Lower Water Neck Rotator For Big Turbo


If you run a large frame turbo,  you should rotate the thermostat housing to clear that bad boy!



With single turbo kits, one of the biggest problems with installation is the routing of the factory manifold. The Powerhouse Racing Lower Waterneck Rotator is the ultimate solution for turning your waterneck away from your turbo manifold on your 2jzgte.

With the lower waterneck in the factory position, there are two problems:

First, the waterneck gets in the way of the runners on many turbo manifolds. Second, the waterneck is blocking the ideal routing for compressor outlet to the intercooler piping. The PHR Lower Waterneck Rotator moves the waterneck out of this terrible location allowing the manifold to fit properly and the compressor outlet to be free of obstruction.

With other brand waterneck rotators, and even the earlier version of the PHR lower waterneck rotator, positioning of the thermostat has had to be moved away from it’s proper location in the housing.

With these designs, the thermostat is moved away from the bypass hole to accomodate the rotator itself, and the thermostat installs in the lower waterneck boss. This new position makes it so the bypass hole can never fully close, so even when the thermostat is open, the bypass hole is not closed and a large amount of the water is not allowed to go through the radiator and be cooled. This reduces the effeciency of the cooling system.

The NEW Powerhouse Racing Lower Waterneck Rotator solves this problem. The position of the thermostat remains in the factory location, allowing the thermostate to close off the bypass hole like it is supposed to and moving flow of all the water through the radiator, maximizing cooling system efficency.
