I have used this item in several "unique" applications and it works great.=

Just plumb it after the first cooler, which is in the rear of the plane and=

Chris,
=A0 =A0 What would be the possibility of getting/salvaging a bypass valve o=
ff a mazda cooler? something that sends cold thick oil though a bypass to t=
he exit, and not through the cooler. As it heats up it opens slowly letting=
 thinner, hotter oil down through the cooler, and once its HOT oil, it ALL =
goes through the cabin heater. This does add complexity to an already probl=
ematic and may not be the cure, but it gives you additional oil cooling cap=
acity which as we both know is a larger percentage of the heat shedding equ=
ation that in non-rotary engines..

=A0=A0=A0If this isn't an option, then you could plumb (like you are asking=
) the front cooler to use hot coolant for cabin heat, and in my best estima=
tion will work just fine for this function. The big outlet on the rear iron=
 is the traditional heater outlet - its the hottest coolant... the return o=
n a stock engine was on the water pump housing. The front oil cooler is mor=
e than robust enough to manage the thinner, lower pressure aqueous coolant.
