How many cc's or how much HP before..., needing an external oil cooler in 914-6? Options

[horizontally-opposed]

Obviously, a 3.0-liter SC motor is gonna want an external oil cooler, but what about a 2.4E or S? Will an on-case cooler do the job, or is it iffy?

Also, who is using the right inner fender for the cooler spot on a /6? What size engine are you running and what temperature extremes have you seen?

Thanks!

Just my opinion, of course, but don't fool around. Put a good cooler in the nose. Mr. Anderson goes along with the factory's
example of a cooler for anything over 170 hp (in a 911) or so, and claims that 6s run hotter in 914s than 911s. I'm not real sure about that last bit but will bow to his expertise..

No ex coolers in the 2.7Ls (165 hp)and look what happened to them. The 2.4L, S motor has 190 hp, so there ya go. The E had 165hp, which would make it marginal. My 140 hp T in the 914 didn't need one.
