Oil coolers definitely make a big difference in temps. i'll be adding one to the Mini before next season. Oil capacity also helps with keeping temps down as Salomon says indirectly.

The stroker 4g63 I'm building will have a moroso extra capacity oil pan and an external oil cooler. Oil capacity should be approaching 9L.
