After market turbo

where do you pull coolant from on a rotary for a turbo? On my other car it was plumbed from the head it's self, seeing as how rotarys don't quite have a head I have the feeling this wont work the same way!

If the motor is already turbo then the cooling is there. One side comes from through the manifold and the other side goes to the water pump housing.

Any coolant source...

The factory turbo 13Bs have plumbing already as mentioned above.

On the NA engines there is a convenient nipple on the rear iron and rear of the water pump housing.

I blocked off my coolant lines because I only have an oil-cooled aftermarket turbo. But here's the question--if I remember correctly the coolant feed is a hardline that is connected to a flange on the motor, correct? Given that there is a flange (as opposed to a threaded fitting like oil feed), how do you use that on an aftermarket turbo? Is there a fitting or flange that you can buy to connect to 6AN lines?

Coolant return is barbed, so that seems straightforward enough.

Off hand, the flange looks to be the exact same size as T3 oil drain flange. So you can probably get a T3 drain flange with an AN flare to fit.
