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 and exactly what you would expect from a small company that is hyper-focused on the details.
I challenged my machinist to produce a dedicated weldable flange that would eliminate the notched, thin-walled tube usually used to connect my billet flanges to the body of my swirl pots, and he did not disappoint. We are working on getting a more uniform tool path, blending those tool paths when fixtures change, and we are getting there… but I won’t be filling orders until we are both happy with the finished product.
The billet flange portion is a 2-piece design that incorporates the original water bypass feature, a relocated M12 x 1.5 OEM temp sensor port, and geometry that mimics the original cast water neck. The end result… a seamless-looking CNC’d part dedicated to making swirl pots!
- 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 Clockings
NOTE: When running our Upper Water Neck on a 1JZ-GTE, the OEM water bypass pipe will be a few mm too long; you will NEED to purchase a 29mm water pipe from RAD Industries.
