Paul and All,
Do you have a recommended radiator and oil cooler, part # and where to
obtain? I know the oil pressure runs allot higher in a rotary than
piston engines. I'll be running the Renesis and I think the rad and oil
cooler will be in a plenum under the oil pan.

Thanks,
Rick

Just about any core that is about 2 inches thick or less and 650 cubic inches
will work for the water rad. Check with Summit Racing.
The stock 2nd gen oil cooler works well but if you can't find one
Setrab oil coolers have a good reputation. You will need a core
volume of about 250 cubic inches for the oil cooler. For a two inch core
that is an oil cooler core about 12 inches by 10 inches. Two one inch thick
cores back to back would also work. Put them in series and plumb
the hot oil in the back cooler first. Keep them thermally isolated
from each other with fiberglass or Bakelite.
