No turbo, no problem.
your blower moter should be fine, stop your car and listen to see if its still on. im thinking its the thermostat. i know its new, but if it s a high performance therm, its going to be cycling more often than a regular one, so its going to be cutting off your radiator from the engine more often. when it stops heating, check the temp of your upper radiator hose. oh, and is your engine temp changing with the heat coming from the vents?
