I wouldn't bother with a external oil cooler unless you are strictly tracking the car. I think it would be overkill for a mostly street driven car.

How does the spec C oil cooler work exactly? Is it hard to retrofit a regular ej207 block to have the same system? I assume I can increase the reliability of the motor significantly through an oil cooler.
Or should I just use a universal oil cooler kit? I plan on occasionally tracking the car in the summer and want to maintain absolute reliability because this car will continue to be my daily driver...
Buying a Spec C motor is out of the equation because it's hard to get and my local JDM places offer great prices on regular ej207s
