I have been doing some research trying to determine what to use when adding an oil cooler to my SC'd track car.

I have come to the conclusion that using a 2nd gen RX7 oil cooler is the way I want to go. The RX7 oil cooler has a thermostat built into the cooler itself.

I found this site that provided information about the RX7 oil cooler: http://www.negative-camber.org/crisp...c/fcpart28.htm

I like that both lines attach to the cooler on one side. No need to run any more line than necessary.

I plan on using a cheap sandwich plate and some -08 lines and fittings. I picked up an oil cooler for $30, so hopefully I can put this all together for under $150.

Am I missing anything?

Don't put the OC between any other exchangers as it will create some major heat transfer. Size has a lot to do with placement. IMO, find a spot it will fit and see what it does for the temps- that's what I'm doing. I found the small trucool wasn't enough for a turbo'd 2.0 in a MIata. I've moved to a mercedes diesel cooler 4x20x2.5 (not quite as big as the 2nd gen rx7). I'll stick it in front of the steering rack first and see what temps do. If I need more cooling, I'll run the vent holes in the OE spoiler to it. I think my biggest issue now is the Hayden sandwich plate with built-in tstat. I'm getting a mocal to install in the current setup to see if there's a noticeable difference.

hmm i have been thinking about putting a 1/2 inch by 6 inch by 10 inch oil cooler on the shelf under my drivers side wiper my measurements say that it would clear any movement there and it would certianly have good airflow etc, and cool the oil just before the turbo.

That could actually be a good idea.

Never thought about that.

Will have to take some measurements and think about it.

sticking a hot oil cooler in there might be nice for the winter (providing it NEVER leaks) but not so nice in the summer - that's where the ac/heat pulls it's air from

What's wrong with the ac/heater pulling air from there? That means the cooler should have a continously fresh supply of air rushing in to replace the air that the ac draws into the cabin. :dunno:

Oh wait, you're talking about the performance of the ac/heater systems now. OK then that would be a drawback for that location.
