We have created a new adapter plate which allows you to run a Gen2 3SGTE water neck onto any Gen3 or Gen4 cylinder head. This works for many people who swap the Caldina Gen4 3SGTE into the MR2, which needs a different routing for the water filler neck. This adapter allows you to take the water neck of the Gen2 and install it on the Gen4. The Rat2 adapter is also built to mimic the factory Gen3/Gen4 water by having a water passage between the multiple cylinder head ports, leaving the factory water system to work as designed by Toyota.
Made out of aluminium, this part is CNC machined guaranteeing a perfect fit on your engine, every time. Lifetime warranty and comes with FREE SHIPPING and where in the USA 48!
