Description
I am so excited to be releasing this badass upper water neck for the 2JZ-GTE market! Totally different from everything you’ve seen before… a purpose-built billet swirl pot flange that eliminates the notched, thin-walled intermediate tubing that usually connects my billet flanges to the swirl pot body.
The billet flange portion is a 2-piece design that incorporates your choice of base: one that keeps the original water bypass feature, one with a blocked water bypass feature that still holds the tube sandwiched between the flange and pump, or one with no water bypass feature… for use with an electric water pump. All bases have a relocated M12 x 1.5 OEM temp sensor port, and a couple of spots that can be drilled and tapped for a small 1/8″ NPT port. The result is a seamless-looking CNC’d part made for swirl pots!
- 6 Second 1/4 Mile Tested – Currently on White Rice Jr.
- Compatible with Virtually All Turbo Setups
- Direct Bolt-On – No Modification to Timing Cover
- M12 x 1.5 OEM Temperature Sensor Port
- O-ringed Sealing Surface (No More Paper Gasket)
- Multiple Outlet Sizes and Clocking
NOTE: The cap bung has a 1/16″ NPT port for overflow connection and uses early-model Toyota radiator caps, such as an 86′-92′ Toyota Supra (PN: 16401-63010). If you are using AN lines, I recommend designing the upper radiator hose with droop/give so the engine’s movement doesn’t push/pull on the radiator and fatigue any parts.
OEM – Water Bypass
