I plan on using an evap core for oil cooling. I have a similar situation where the 2nd gen oil cooler won't fit. Plan B will be as a result from talking to Pacific Oil cooler guys. There is a 19 row cooler (Aero Classic) that could cool the rotary and is similar in size to the evap core. Keep the reports coming. Thanks.

Hey, quit talking about me like I'm not here :-)

I refuse to believe the stock core is all that special. I do know that I can't fit the long stock 2nd gen core, but could possibly fit a 3rd gen core. I doubt one of those would be enough though. I'm sure the evap core will be just fine, once I get the airflow straightened out (get it, straightened... never mind). I could do unlimited climbs at 90 mph an 90+ degrees F before I went to the C drive, so the extra power is what's causing me problems. Even now, I'm probably only 15 degrees away from being able to climb at will. If necessary, I still have the Setrab cooler that I used in an earlier revision, and I'm sure that will do the job. It might even fit.

Cheers,
Rusty
