* RAD DAN SUPRA ITEM *
The RAD Industries billet 2JZ-GTE RACE VERSION Upper water neck with -16 orb port. This product was designed with simplicity in mind while still maintaining the clean machined billet look in your engine bay. It offers the same functionality as the the original RAD Industries Upper Water Neck but we have minimized the overall size allowing the end user to run larger turbos without interference issues. We have also removed the rear recirculation port for the OEM water pump, making this part strictly for electric water pump race cars. (If you are still running an OEM water pump, you need this RAD Industries Upper Water Neck) With the female -16 orb threads you can choose between a -16 AN (980016) or -20 AN (980021) for your upper water hose.
• There are 3 threaded ports on the bottom side of this Upper Water Neck; 3/8", 1/4", 1/8" NPT (plugs included) We chose to include 3 different sizes to accommodate different combinations of sensors for a variety of race car builds.
• M8 x 1.25 HARDWARE INCLUDED for mounting water neck to head
* Uses o-ring to seal to head (included), OEM gasket not required
WATER OUTLET THREAD PITCH: -16 ORB Female
