Water Neck Adapter - Gen3/4/5 3SGTE
This adapter is a complete conversion kit for the GEN2 3SGTE coolant neck (stock component on any 91-95 MR2 turbo). The adapter is o-ring sealed on one side and factory sealed on the other side. In addition to the adapter plate we provide the water neck o-ring, 2 new studs and 3 new nuts (you can re-use one of the existing studs). You can either use a E-socket or double nut the existing studs to remove them.
This adapter will allow the use of a GEN2 water neck on any Gen3 or Gen4 3SGTE.
