Phizinza Posted March 3, 2006 Share Posted March 3, 2006 The turbo coolant outlet does not dump into the head. The turbo coolant outlet dumps into the Thermostat housing. Sorry, I don't own a EA82T. Just thinking of ways to keep one cooler. Wouldn't seperating the turbo coolent and oil keep the engine cooler? They do glow after all. What difference does it make that the coolent out of the turbo goes the the thermostat instead of to the heads.. Doesn't it end up going thru the heads after the thermostat. Or is the flow of coolent the other way round? Link to comment Share on other sites More sharing options...
WJM Posted March 3, 2006 Author Share Posted March 3, 2006 The reason for the goinormousness and redness of the next is because the EA82T has been around for over 20 years now...and still people think think the coolant flows backwards then what it really does. The entire purpose for the coolant+oil cooler turbos are the increase turbo life. PLUS...you reach operating temps WAY faster in the engine as well....which is, believe it or not...a GOOD thing. The ONLY reason for oil only turbos are racing or aftermarket where they decide 'nah, not on this one...maybe the next one'... I've installed all kinds of turbos...MOST of the time they are water-oil...rarely do I see oil only these days. Anyhow...after the coolant dumps into the t-stat housing...it all flows out thru the upper rad hose to be cooled by the air. On an EJ...coolant flows out of the head, into the turbo, out of the turbo and into the coolan reservoir tank on the turbo side of the engine. It has 4 ports. One for the rad cap-system pressure overflow....1 small line that feeds directly to the top corner of the radiator....the turbo coolant-outlet-inlet...and on the bottom of the tank, a line that goes back around to the waterpump right at the t-stat just like on an EA82T (well, except for the waterpump part...but still, both outlets end up going back to the t-stat).

Myxalplyx Posted May 4, 2006 Share Posted May 4, 2006 Late reply but I guess this will thwart any efforts at turbocharging my XT6. Then again, I only have to monitor closely the coolant temps. I would definitely put an EGT gauge on anything that is modified with a turbo. When going N/A to turbo, I would try to shoot for EGTs the same as running N/A.

torxxx Posted May 4, 2006 Share Posted May 4, 2006 hehe, after reading this thread, it confirms my SCREW EA82T's. I'm actually pissed off that I wasted my money on a RX for it to blow up in 2 hours. Easiest solution for these engines is: DON'T BUY ONE Link to comment Share on other sites More sharing options...

bgd73 Posted May 4, 2006 Share Posted May 4, 2006 5-6mm is not too thin. Maximizing cooling dissipation needs it. If you exceed its ability to cool, it is your cause of problem.If a siamesed bore 400c.i. GM can run at "holy cow" HP(horribly extreme example). An aluminum suby can go quite far. Drop thermostat, and many other things to take the super heat of the super thing you did to get it super hot:) Link to comment Share on other sites More sharing options...
NorthWet Posted May 6, 2006 Share Posted May 6, 2006 After looking at manual diagrams, and not as yet having actually torn open the cases on an EA82 (Summer come quickly!), I have a question: Is it true that the only coolant passage to the "turbo"/non-disty side of the engine is through the little transom-port at the top of the case joining surfaces? And is this fed from the disty-side water jacket, or does it get some dedicated flow from the waterpump? The reason I ask is, that if I am interpreting the diagrams correctly, no significant waterflow reaches the non-disty side case (and head) if the water level in the disty-side water-jacket drops below the transom-port. If so, this could at least partially explain why the turbo side head cracks (apparently) more often than the disty-side. The "secret" may be as simple as water level and water flow. (FYI: I have been told that 2-row radiators are no longer being manufactured by the major aftermarket companies. ) Link to comment Share on other sites More sharing options...
ausubaru92 Posted May 8, 2006 Share Posted May 8, 2006 Come to think of it,.. I agree So somehow we have to find a way to provide more coolant flow into the turbo side head,.. but how???? Link to comment Share on other sites More sharing options...
