Have a modified RX7 Oil Cooler that came with the car which was in process of a 6 conversion. Hoses are run to the engine bay ready to hook up to thermostat. Does anyone know if it matters if the oil enters from the top of cooler or bottom or does it really matter? Internal Tank thermostat is removed already I am going to run a Mocal. Appreciate the input especially from anyone actually running one. Thanks!

Do you have any more pictures you can post of how it's mounted? Also, are those electric fans mounted on the back side of the cooler? |

[/quote] Yes I have pictures of the fabricated frame and fans that I cannot take credit for making because the PO did it and a good job at that! Trying to post pictures but not working for me this time will try again later. Sorry |
