LC80 Oil Cooler Upgrades

Endless, do you feel that there is a need for an upgrade? Just curious. Seems that the OEM cooler does just fine. I have thought about upgrading hoses and stuff to the pretty braided stainless and colored aluminum fastners and ends.
 
Endless, do you know of a good place to find braided stainless hoses to replace rubber ones on the 80? like for the radiator and such?
 
Search for some projects submitted by Photoman. He added a lot of usefull mods to his rig including some additional trans coolers. Not sure if he did anything for oil or not.
 
The blue thing pictured looks like it replaced the transmission cooler (or did they just paint the OEM one and put nice lines on it?) , the engine oil cooler is located on the side of the block under the exhaust cooled by coolant, the tranny cooler is already quite large, not sure replacing it will get you much for your effort,


The power steering cooler on the other hand is a weak spot, tends to rust and cause problems, and is kind of small, replacing it might be a good idea. If you replace it the stacked fin ones supposedly flow better then the winding tube variety,
 
Endless, check into the oil cooler for the Mazda RX7 turbo. It's a nice heavy duty aluminum one that fits nicely lower along the bottome edge of the AC evap. A little thick but it's about the same thickness of an intercooler - which sits nicely above the oil cooler. Good ones are on eBay regularly for under $50. Hope this helps.

Now if you talking about direct replacements for the 80 its so far i havent seen '
em in the states.But for the universal kit you can check @:

clownmidget, What year the RX? you mean stock factory RX?

Hey, but actually my point is that really necessary to upgrades it?

Haven't ever heard of any issue related to it. Pehaps Cary our fairytale (meant in a positive way) personal 80 oil guy will chime in.
 
endless, yeah oem like this (http://cgi.ebay.com/ebaymotors/ws/e...tem=7953890202&category=46095&sspagename=WDVW).

Something like 1987-1993 or so. One nice feature related to the braided lines is that it has the threaded banjo fittings already. Of course you'll still need to rely on a plain old hose clamp on the other end where it mates to the bottom of the rad and the hard line from the tranny.

I think the one reason to investigate relocating and possibly upgrading this is in cases where you would want to install an intercooler and then the stock cooler is in the way and will need to go. Once you stick that intercooler up there you'll be left with a pretty limited space to put the oil cooler - about 20" to 24" wide and maybe 6" or so high.
 
Yes that pics above from Greddy and GREX oil cooler kit.Hey Turbocruiser can you post the pics of your car where exactly mounted behind the ARB bumpers with all the necessary fittings and stuff? Im just wondering the Safari kits looks like:rolleyes:
But in terms of longer life do you strongly recommends to get the better flow compares to stock?

Thanks
 
Turbo, just not to confuse what is being discussed, the cooler you have as part of your Safari system is a transmission oil cooler. The turbo is cooled by the engine oil but none of that gets routed through any additional coolers.

2: Safari must think that the motor oil requires NO additional cooling than with the stock setup.

Maybe #2 more than anything so far proves that the stock oil cooling setup is sufficient EVEN WITH forced induction. If so that is impressive. Since the Safari system in general, as I mentioned above, is so specifically reliability minded, and since they apparently left "well enough alone" with the oil cooling, I gotta wonder why anyone would need more oil cooling. Is my thinking off on this? I wonder whether anyone has an oil temp gauge or even better does someone with stock engine AND someone with forced induction have oil gauges to compare the stats?

Sound logic IMO, the stock IFZ water-cooled-oil-cooler is quite large compared to the Tacoma V6 cooler (little larger than a tuna can), it looks expensive Toyota put quite a bit of effort into it, oil coolers are rare in other vehicles

No oil temp gage but I have a non contact IR thermometer, after a 35 mile freeway commute on a upper 80's spring day checked the oil pan, trans pan T-case and diffs,

oil pan is 191*F,
Transmission pan 141*F,
T-case 188*F

The oil and transmission seam quite acceptable to me, both have excellent stock coolers that are comparable to “heavy duty” aftermarket units, towing, stop and go traffic or extreme tropic climate may change that, but I rarely see any of those.

The T-case on the other hand surprised me,

The quickness the PS fluid darkens also bothers me, as does it’s the PS cooler poor track record for reliability, also PS systems tend to get very hot on trail,

For a standard normally driven 80 I would look at those two before I bothered with the engine oil and transmission, if you routinely pull a 10,000 pound trailer through metro traffic or pikes peak then defiantly trans cooler upgrade (or buy a truck)
