Best way to add heat to a Subaru conversion? Options

[CptTripps]

I would like to add heat and defrost to my Subaru conversion, but I'm not sure the best way to do it. Now, I'm no expert on the ventalation system of these cars, but I was hoping to have something simple like 2 discrete motors. One for the vents on the dash, and another for the defrost.

The stock heat blowers are intact on the car, but I don't believe they're hooked up at all, since the PO had a SB350 installed. That motor is going bye-bye, and I'm not sure the best way to add something to replace it. I don't need fire shooting out of the vents like my Land Rover, just enough to get the windscreen clear and take the edge off of a cool night.

I see a few aftermarket blowers that I can put in-line with the heat tubes, but how should I GET the heat? Is thee a way to do it from the water in the radiator?

I'd look at a motorcycle oil cooler, mounted in front of the tubes in the engine bay and plumbed in the water system. Fabricate a shroud to connect the cooler to the round pipe and put a fan on it. One on each side probably. Wouldn't need a valve in them, IMHO. Just control the fans. And use the stock diverter valves to control direction.
