bus boys sells a heavy duty oil cooler with a fan that can be controlled by
a temp sensor and it has an oil stat. this is connected to the oil filter
with the use of an adapter that would sandwich between the block and the
filter. I'm not sure how the current 2.1 configuration would allow this to
work. Gene berg sells a oil pump adapter that would have an oil line take
off from the pump cover and you could have the return come in at the dynamic
warning oil pressure switch position but it would be a tight fit
I have allot of air-cooled customers that use this set up and like it. they
mount the cooler above the trany for safe keeping.
I recall that someone had some statistics on highway RPM or MPH and oil
temps a while ago

going faster miles an hour without an oil cooler
