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? |

Just an opinion on drawing fresh air from the engine compartment on a conversion car. Unlike the stock 914, where fresh air is drawn from the top side of the motor/engine tin through the engine grill (fresh, un-contaminated source with constant flow), drawing air from the engine compartment on a conversion car (non-Porsche) and blowing it into the cabin is potentially dangerous. I'd be mostly concerned with CO, aside from oil fumes, or fuel vapor.

So no engine fumes. Having said that I did not ever use this system. Just liked it's overall concept |
