Looking for new Oil Cooler and PS cooler

This is a small start. I could swear I wrote a lot more on the subject in the past but I don't have the time to look for it right now. http://www.toyota-supra.info/forums/...il-cooler.html

The stock setup uses pressure not temperature to determine when to send oil through the cooler. It is also a bypass setup, meaning that it only sends a portion of the oil moving through the filter head to the cooler. All around it's a weak system. The preferred setup, I feel, is a full flow cooler setup with thermostat. You remove the whole filter head from the block of the engine. Install the N/A's oil filter nipple which allows you to place a filter or block adapter directly to the block without the larger filter head/cooler valve assembly. Run 1/2" or -10AN hose to a thermostat from both ports on the head (flow direction is labeled on all components usually). Then from the 3rd and 4th ports you run the hose the rest of the way to the cooler. You'll want to install the remote mount filter head in the line running from the block to the thermostat. Try to avoid using 90? fittings and tight bends of the hose to reduce pressure and flow losses. Always use filters with an anti-siphon valve (most have this).

For the power steering any 12" single row transmission rail cooler will work fine. Anything more will be a waste of space and money. If it has a lot of fins 12" is overkill already. Consider adding a filter to this line as well... Your engine, power steering, transmission AND cooling system deserve good filtering.
