Oil pressure/cooling protection
We need experience input. In our rebuild, 2.258engine keeping the stock oilcooler and tin, we are now thinking about keeping the oil pressure stable and have added cooling protection. Loss of oil pressure occurs with hard cornering and can be prevented by the use of a deep sump.
My understanding is that a deep sump 1) does not provide for significant cooling 2) because of its location, is prone to road damage.
External oil coolers provide for increased cooling capability and increased oil volume but I don't believe it prevents loss of oil pressure at the sump level. I noted a mention of an, "Accurapump (sic)", but have not found a site for further information.
Thoughts?

Sump extensions provide a little bit of extra surface area and so will help cool the oil a tiny bit. From what I can tell, the difference is too small to notice. It will increase your oil capacity, which means it will take longer for your oil supply to change temperature--to get up to "normal", to get too hot, to cool off after a drive, etc. An oil cooler, of course, will provide a lot of cooling capacity. And will also increase your oil capacity.
I like the small "tuna can". It holds enough oil for one good sweeper in my experience, or a couple of off-ramps. (Less if you have really grippy tires and suspension; more lateral G's == more oil getting sloshed away from the pickup.) I find that it does not stick down as far as the motor mount bar (side-shift version, at least) does. It does stick down, however, so it is possible to waste your engine by getting high-centered. The full-size deep sump is larger, so damage is more likely.
The Accusump can be mounted just about anywhere. Its capacity is at least one full quart, but larger ones are available. This should keep oil going through the system for significantly longer than the ~1/2 quart of the "tuna can". However, it is somewhat more complicated to install and it costs much more.
The "best" solution to both problems (oil pressure and heat) would be to install both an Accusump and an oil cooler. I am happy with my tuna can, however.

The dry sump setups that I have seen will not work with stock cooling. (Remember, that was one of the constraints listed in the original note.) The pumps are simply too large to fit between the engine and the fan shroud. Fine for upright-converted engines, not so fine for the rest.
Hot Wheels, will your setup work with stock pancake cooling?

I and others have had problems make the "tune can" sealing properly - has to do with the angle on the pick-up pipe.
Went to Accusump.
