RX-7 Oil Cooler Help

[bander]

I am putting in an Rx7 oil cooler and need to know which of the fittings is the inlet and which one is the outlet, if it matters. I still have the stock thermostat in the cooler and a thermostat in the sandwich plate.

I saw a link to a page a few months ago that showed the different RX7 coolers but I can not find it now.

Unless I hear differently, I think that I will go into the lower fitting and out of the upper one.

Thanks

This topic comes up quite often on the 911 board. Apparently there is an internal thermostat you have to remove. This thread should get you started: Radiator-style Carrera oil coolers

That would be my cooler being discussed.

I didn't put it in, so I have no idea if it has a flow direction. Given I was told it has a pressure limiter in it, it may well have a specific flow requirement.

I am very interested in this as well. I read the attached link/thread and have a couple of (hopefully) easy questions....

1. What year rx-7 has the appropriate cooler?
2. Is changing the AN fitting size a requirement or can you use the cooler "as is" (this is for a 4 cyl application)
3. Can someone explaing the internal pressure limiter feature and it's benefits/pit falls?

Thanks!
