a few quick questions.
 

that has an electric water pump on their 13B turbo or N/A? How did you do it and where did you get it.? Any benefits from this on a street car.
And, any benefit other than the obvious ones from adding an oil accumulator tank

Bro, here is a member selling his setup if you are really interested in doing it, its a good deal:
