the coolant sensor on the back of the water pump housing.............are they all the same for the N/A's and TURBO models or are they different and need to be upgraded when doing a turbo build with a turbo ecu and harness?

 

now i dont know for shure, but when reading arron cakes high compression turbo or 6 port turbo it says nothing about swapping in or changing them out.
hope this helps but im not entirely sure, there people with way more info that could help.

 

They are the same.
