I was wondering if an oil cooler like this one would work as a front oil cooler of a 2.7 6 conversion.

What are your thoughts? BTW it's a Behr from an old Mercedes.

The one I have is out of a euro-spec Mercedes M110 engine (2.8l DOHC inline 6 with 185HP) but that engine is pending sale along with my car.

I was just outside and thought the dimensions were close to the 914/6 GT coolers and since it helped with a 2.8l inline six.....

I'd have to find another one, but I'm sure they are out there.

Thanks to all you guys for your help. I'll probably run either braided lines or those cool GT-style hardlines to the front (the ones PMB are doing). I've been told a front cooler is best, so what the heck.

If anyone has a line on a good RX7-cooler or of a place to get one, I'd be willing to think about that too.

I have two RX7 coolers for, say $ 30 each. I used one for a while with the thermostat plugged off since I have a mocal in line tstat. They are a great fit for a front mount setup. However, do a search on Rx7 coolers here and you'll find the thread on how to remove the strips from inside the tubes & re-weld the tank on the end......without doing that the cooler is very restrictive when the oil is cold & causes an oil pressure drop when the tstat switches. Let me know if you want one.

Not to start an argument, but:

Since the cooler is on the scavenge side of a six pump and no pressure is measured there, I fail to see how it would effect the oil pressure in the engine. The oil returning to the filter and tank is what is cooled.

A six pump is a flooded suction pump with 8 quarts of oil in the tank feeding the engine oil pump.
