are oil coolers necessary?
 

I am replacing the engine in my black 07 ms3. we won't go into what happened but i do want to make this engine last as long as possible after putting in the $. first, are oil coolers necessary for someone who will drive their car very hard on AutoCross events and occasional spirited driving in the mtns?

since i (will)have a brand new engine i would like to protect it as much as possible. would an oil catch can be a good idea? sounds like one to me but i will admit being on the noobish side. i was looking at JBR and Corksport. main diff to me is that the JBR offers a check valve in the stage 2 kit while Cork doesnt offer on at at all. does this limit the Corksport to lower powered setups?

thanks! any help is appreciated.

We have a stock oil cooler that uses coolant to cool the oil. With that said, I would recommend an upgraded radiator from ron Davis racing, I think mishimoto offers one as well.

You, my prematurely posting friend, need to do a lot more reading on this site in order to understand the platform better.

On a DD car an oil cooler isn't necessary, even an occasional spirited drive, you'll be fine. Frequent AutoX or Track days I would strongly suggest one if you don't have an upgraded Radiator. See links below. IMO, upgrade your radiator and don't fret with an oil cooler.

An OCC question? Lack of research. Theres a How-To for this as well. For any MS3 (DD or track), I would strongly suggest one. I learned this from personal experience. Get the JBR. Get the Stage 2 with the check valve. The check valve prevents blowing up the OCC, amongst other things. I had a shitty secondary PCV valve, then switched to a quality check valve.
