WJM Posted March 29, 2007 Share Posted March 29, 2007 Ok, so I finally got the DEFI gauges installed last night, after that I went out for some more tuning. I installed...EGT, Oil pressure, Oil temp, Water temp...I have a fuel pressure gauge, but no fittings yet, so that will be for later. Oil pressure was good. When warm, 18~20 psi at idle. 58~60 at cruise (anything more than 3000 RPM). The oil temp leveled off at 220F during cruise and long periods of idle time while I was changing the map. However...during ONE 3rd gear pull, the temp would rapidly climb to 230~235 FAST. 240F is where most people put the limit, its too hot. SUBARU runs the all of their EJ turbo engines at 200 F oil temps normally. On autox runs, spirited driving, they'll get to 210 and no higher...no big deal. During tuning pulls, the oil temp gauge (when one has such gauge) doesnt even flinch. I believe that the EA82T has a serious oil heat buildup problem under the conditions that most of them put them thru. Unfortunatly, the oil cooler equipment that came on the EA81T, it all gone forever, cannot get it from SOA anymore. Link to comment Share on other sites More sharing options...
Reveeen Posted March 29, 2007 Share Posted March 29, 2007 Something like this: http://www.thepartsbin.com/sitemap/subaru~oil_filter_housing~parts.html ($60) plus an oil cooler in-line? Plus too, you get a listing of engines (that may, may not have a oil cooler installed) that you can keep an eye peeled for junkyard parts. I wonder how the temperature would change with a large remote filter that had some air flow around it. Link to comment Share on other sites More sharing options...

So that will work on my RX? I already have the cooler, but no attachment Link to comment Share on other sites More sharing options...
Snowman Posted March 29, 2007 Share Posted March 29, 2007 So, do the EJ turbo soobs have an oil cooler from the factory like the automatic foresters, or is it just the larger oil capacity that helps them stay cooler? I'm still trying to track down one of those coolers if anybody has one, as I do lots of 80 mph plus driving for hours on end, and I worry that my oil temps might creep up there during the summer months. I also think that an oil-to-water cooler like that would help to keep the oil warmer in the winter, when I often find it cool to the touch after long stretches of highway driving.

I can't speak to US spec cars, but mine has an oil cooler. Link to comment Share on other sites More sharing options...

Anything that ads oil capacity to the lubrication system is a good thing. Remote oil filters will also expose more oil to the air. I may be wrong, but Ive seen a cooler that went in like a sandwich plate, fed the tstat housing, and returned. I wish i kept that picture. nipper Link to comment Share on other sites More sharing options...
Reveeen Posted March 29, 2007 Share Posted March 29, 2007 So that will work on my RX? I already have the cooler, but no attachment It should. The listing has other cars that the remote filter kit fits, so I would *think* you could turn up something at a junkyard that would fit, maybe a Ford 2.3 Turbo? When doing external oil lines make sure to use "proper type" hoses. Link to comment Share on other sites More sharing options...

I ran into serious overcooling problems with my automatic transmission this winter, and I'm sure the same would happen if I installed an oil-to-air cooler for the engine oil.

I wonder how the temperature would change with a large remote filter that had some air flow around it. it says '81-'89 GL, so I would suspect they mean EA81. I couldn't find the same part for an EA82, but found this: http://performance.thepartsbin.com/basket.php?makeid=31&modelid=503&year=1992&partid=536&brandid=3705 scroll down past the tranny cooler ones, and there's a full oil cooler kit. none of our subarus have had factory ENGINE oil coolers. but all the autos have a seperate core in the radiator for the tranny fluid (heck...so does my toyota). you could probably get a radiator for an AT and just plumb into that.

mikeshoup Posted March 29, 2007 Share Posted March 29, 2007 it says '81-'89 GL, so I would suspect they mean EA81. Should work on the EA82. EA81s use the same oil filters as the EA82, so the fittings are all the same. Link to comment Share on other sites More sharing options...

I highly doubt that the little 3/8" tranny cooler lines in the rad are big enough to not result in restricted oil flow. I would also imagine that that the tranny cooler portion of the radiator is not meant to contain engine oil pressure. It typically sees just a few pounds of pressure.

Reveeen Posted March 30, 2007 Share Posted March 30, 2007 For years motorcycle guys have been able to buy oil cooler thermostats that cause the oil to by-pass the cooler if too cold. I have never bought one: 1) because they are expensive. 2) I get nervous adding stuff that could break down in vital engine systems. I *think* that maybe a remote filter kit with the filter mounted in an area that recieves air flow might do the trick. Link to comment Share on other sites More sharing options...
WJM Posted March 30, 2007 Author Share Posted March 30, 2007 Yeah, ALL of the US-Spec EJ turbo engines came with the oil-water oil warmer/coolers....as well as the 4EAT Foresters. It sure does get the oil up to temp fast, and keep it around 200 F under normal conditions. All of the EA81T's that the US got had the oil-air coolers...and as far as I know from the information i gathered...ALL of the non-US EA82T's got oil-air coolers. Only the USA didnt get them. Also, many MPFI-N/A EA82's also got oil-air coolers. Link to comment Share on other sites More sharing options...
86BRATMAN Posted March 30, 2007 Share Posted March 30, 2007 If you can use an ea81t factory oil cooler let me know quick. I'm going to the junk yard tommorow, for an ea81t engine crossmember. I'll be staring at the cooler for a little bit. Link to comment Share on other sites More sharing options...
rllywgn Posted March 30, 2007 Share Posted March 30, 2007 the oil cooler i thought i might use on my ea82t is from a second gen rx-7 although im thinking it may be overkill due to size and may be difficult to find a good place to mount.. volvo's particularly the 740's have a somewhat small oil cooler mounted just in fron of the radiator that looks promising.. (should be) easy to mount and the lines are straight forward.. there was a thermostatic oil sandwich adaptor that i had seen for sale (ebay?) but it was listed for a nissan.. sentra maybe.. need to google it i guess thought i had heard about it here Link to comment Share on other sites More sharing options...

There is an 83 ea81t wagon that I'm getting the endine crossmember out of, possibly today if they can turb the car on its side for me. If not it'll be tomorrow. I can get the cooler if you don't mind used. Link to comment Share on other sites More sharing options...
