Question Oil coolers, what are my options?

I know about the Subaru oil cooler, but are there any oil cooler kits out there that would air cool the oil with a dedicated radiator? I would think that an air cooled system would be much more efficient and easier to install in the aspect that I wouldn't have to touch the coolant.
Thanks

Thumbs up Oil coolers.......

Hey Jay25rs, Rallispec makes one that is the same price as the OEM subaru oil cooler (which is $400 right). anyway, the rallispec oil cooler is also $400 dollars.

The rallispec oil cooler sits in the lower bumper air dam, and has direct airflow. it' so cool, and sorta looks like a small intercooler!

I know rallispec's site is down.........www.rallispec.com

but, check---- www.subarureview.com --------- click on impreza 2.5rs section and go to engine products, it should be at the bottom.

hope this helps, seeya later

A water to oil cooler will not drop temps as much as an air to oil cooler, but keep in mind that a water to oil cooler also warms your oil more quickly when the engine is cold. (the oil is the last thing to warm up) Also in very cold weather, an air to oil cooler may overcool your oil. For the average streetcar, even a modded one, I personally think that the water to oil cooler is plenty efficient enough for cooling, with the added benefit of warming the oil faster at startup.

I once saw on TV an oilcooler that had a thermostat in it so that it wouldn't open until a certain temperature thereby allowing the oil to remain in a closed loop until it hit the desired temperature. Also, one time I saw an automatic transmission cooler setup where it was air cooled first then water cooled so that it would build temperature quicker.

Rallispec's site is down because Rallispec is down, so I'm thinkin' you'll have a hard time finding a Rallispec oil cooler kit.

We discussed different oil cooler possibilities in the NESIC Forum a couple months back - check out http://i-club.com/forums/showthread....ght=oil+cooler for quite a bit of good info.
