I found this oil cooler in a catalog that I get. I don't know if anybody here has priced engine oil coolers, but my NAPA told me the cheapest one they carry is around $150, and is sized for a V-8.

This surplus place is right here in Lincoln, Nebraska. I have gotten lots of stuff from them, and it's all good stuff.

Here is the cooler I plan to use in the spot where my intake muffler used to be.

And here are all the coolers that they offer.

Dude, this is the spec's of the unit your looking at :

Oil Cooler


• New HAYDEN. Oil cooler for hydraulic systems, engine or transmission coolers, etc. Copper tubes with aluminum fins. 3/4" diam. cooling tubes.
SPECIFICATIONS
• GPM 6
• PSI 300
• 350° F
• Ports 1/2" NPT
• Cooling fin area
12" x 3" x 4"
• Overall size 16 1/4" x 4" x 5 3/4"
• Shpg. 7 lbs.


**I'm worried that with the GPM6 equals 6 Galloons Per Minute
Which makes me wonder What this will do to the Oil PSI?

Am I just being too cautius?

Well, I'm not sure. I haven't actually gotten down there to have a look at one yet. Although, it states the tubes are 3/4 inch, which is the same size or bigger then the pick-up tube in the pan, so I don't see that it would restrict flow too much...

And my Subaru's only hold 1 gallon of oil, which means this cooler could pass all the oil in the engine 6 times in a minute...that seems ok to me, but I'm no oiling system engineer...

Here is a pic of the one that I am useing.

It's sold as a tranny cooler. But that doesn't really matter, cause a tranny cooler is just an oil cooler anyways, it's just cools the oil in the tranny. It's got 3/8ths inlet and oilet, and doesn't effect my oil pressure but it seriously cools things off good. Before I put it on there, if I had my motor running with the fan on, and not moving, my engine temp would get about an 1/8th of an inch over half on the guage, but after the oil cooler, the temp now sits at about 1/4 in the same situation. I've never had my temp go over half now.

HuH?! It usually pops up with a little box when I get a message, didn't do it this time, had to go in and check my messages manually. Thought I'd share on here, so everyone else could know.
As most people know I've got an 84 Hardtop Turbo, EA81T. Well, I managed to uh (cough, cough) pick up a motor by pure luck, whole motor (sans turbo unit, what I need). Well, it didn't dawn on me untill almost 3 months after I got it, when I was cleaning the find on the OC on my car, the EA81T's had an oil cooler that sat between the filter and the pump. It's a real simply set up, and if I sat down and looked at it long enough, I could prolly machine some up. What it is is a round piece of metal, it has a bolt that is threaded on both end and is hollow, the bolt goes though the OC unit, and threads into the part of the pump where the filter would screw in, then the filter screws into the bolt. Oil flows into the filter like normal, but after it comes out the filter it gets diverted through a pipe to the cooler, then returns from the cooler and goes into the pump where it would go if it came from the filter. (anyone understand that? Should I draw a picture?)
But anyways, if I get some time and little cash to play around with, I'm going to try and reproduce these, as they are really simple, I think that the hardest part would be the bolt it's self, as the rest is just machine work. Hope this helps.

Ohyeah, if you ever see an EA81T, check the oil pump, if there are two lines coming off it, pointing towards the drivers side, this is the cooling unit, grab it, just take off the filter, then use either a 19 or 7/8th wrench on the larger bolt in the middle of it, and it comes right off, and getting a new gasket is easy, uses the same one as the oil filter..

These are already commercially availiable. Perma-cool makes them, as do a couple of others.

Look here for the perma-cool one.

Most of our older subarus will use the 3/4"-16 threads. I was surprised my self, but I found this out when I bought the pieces to relocate the filter on my 86 XT with EA82T. This means they will take a larger filter too, like a Fram PH8A, which is used on most Ford V-8's, like the 302.

Did some more testing, and found that, although the older EA-81s and EA-71's call for a different filter, they are the same thread and gasket size as the shorter one the EA82T calls for. Also, the same (thread/gasket wise) as the filter for a 91 Geo 1.0 liter, as well as the PH2 that my Crown Vic uses.

I hope somebody finds this to be useful in some way, shape, or form.
