I was thinking about installing an oil cooler. I think the easiest way to do it would be to find one with 4AN fitting and just put it on the oil feed line to the turbo. This would cool the oil going to the turbo, but the cooling affect may not even make it into the motor after the turbo heats the oil up. Does this sound like a good idea? Anyone know of a good oil cooler with 4AN fittings?

i use a dual circuit oil cooler (2 coolers in 1).. one for the block and one for the turbo.. it does help heat thats for sure. its just rough to install because you have more lines running and they could leak.
