dat240zg Posted October 18, 2002 Share Posted October 18, 2002 Curious; has anyone tried to use one of the radiators from an automatic Z with the tranny cooler integrated into the radiator and switch the lines out to work as an oil cooler? Is there any reason why that wouldn't work? Possibly too restrictive? I have one sitting in my barn and was wondering if it would work as an oil cooler in my turbo swap into my 240...

Mike C Posted October 18, 2002 Share Posted October 18, 2002 I think you are spot on about the restriction. Oil cooler lines are typically at least double the diameter of the auto trans lines cooler lines. I think you can get a rad with a heat exchanger built in it that will have sufficient flow to function as an oil cooler, but if memory serves they cost as much as a good used Datsun...

johnc Posted October 18, 2002 Share Posted October 18, 2002 C&R makes really nice ones. Figure about $1,000 for an aluminum double pass with a 4 plate heat exchanger. Quote Link to comment Share on other sites More sharing options...
turbobluestreak Posted October 28, 2002 Share Posted October 28, 2002 no do what I did I bought a turbo 2 rx7 oil cooler for $15 mounted it in front of the raidator and had the place where my dad works make me the lines to run it, or you could get stainless line for a good price. The Oil cooler doesn't go for much on ebay and keeps my oil really cool too. tbs Quote Link to comment Share on other sites More sharing options...
Mike C Posted October 28, 2002 Share Posted October 28, 2002 I wonder what kind of oil filter that older Ford cop cars had? Since the Z motor uses the Ford filter, a sandwich adapter and the copcar cooler could be used quite easily. Quote Link to comment Share on other sites More sharing options...
Tony240ZT Posted October 29, 2002 Share Posted October 29, 2002 I have a sandwich plate on my orange Z with the L series, got it from perma cool. Am using a B&M oil cooler. I have one of the Rx7 coolers laying around and was hoping to use it on my silver car, but it may be too larger to fit in with my FMIC. They are super nice! I T'd off of the oil return line from the cooler with a SS braided line half the size of the main engine oil feed for the turbo. Quote Link to comment Share on other sites More sharing options...
Guest Zachb55 Posted October 29, 2002 Share Posted October 29, 2002 when you guys ad the coolers do you feel the need to use a higher viscosity oil? it seems like those would be so effective that maybe a real low viscosity oil might not flow well and build up in the cooler, which coul obviously lead to badness... -ZAch Quote Link to comment Share on other sites More sharing options...
Tony240ZT Posted October 29, 2002 Share Posted October 29, 2002 I put on the turbo on at the same time as putting on the cooler, and I changed my oil pump so hard to say exactly with all of the changes. Anyways, I'd say my oil presure acts about the same as it did when the engine was a NA with SU's and old pump. Oil cooler gets pretty warm when I drive hard, but not so bad if I'm just cruising, over all I'd say it does it's job well. I've got some pretty big lines going into the thing, and it has some good sized fittings on it. Maybe since I have an aftermarket one it flows more than some OEM ones, but no proof. There's probably only one perfect sized oil cooler for a particular engine, but how to figure that one out and if it really makes too difference is another question that may not matter all that much in the end. These engines last pretty dang long as is, even without oil coolers. Running a center piece in your turbo that allows you to run water may help more than a larger cooler, who knows. The RX7 cooler is by far the cheapest and largest you can get your hands on, that's the only answere I'm really sure about Quote Link to comment Share on other sites More sharing options...

Your thinking backwards, you would be able to stick with low viscosity oil for better flow with a cooler. Oil temps in my car have gone up to about 270º IIRC, with a cooler and 6 quarts, stock cooler in a 94 Camaro. Road racing gets the car hot pretty fast, especially in 90º+ heat.
