This modification is for the Gen4 3SGTE engine ONLY. When you swap a Gen4 3SGTE into your MR2, you also have to track down a hard to find Gen3 water neck in order to finish your swap! We take the existing Gen4 water neck and modify it to retain your factory coolant cap, all the while really cleaning up your engine bay!
This price assumes that you will be sending us your Gen4 water neck to be modified. These cores are rare, so we require you to send us yours after you place your order. Turn around time is typically 7-10 business days.
