2 questions about Turbo & Brake Servo

[Dragun]

Hello

Just a few queries I'd like to run by you guys.

First off, shortly I'll be installing an efr series turbo, could someone
tell me the best location to get the water feed and also best place to plumb
the water return too. Pics would be great. (All units I've ever installed on the 13b
always been oil feed only).

2nd. Has anyone had any experience with this unit?

I like Idea, but most forums don't have good things to say about the company, but found nothing
on this specific product.

Many thanks

Rob
