Mocal oil cooler & sandwitch plate ordered

Dont understand your story, but yes you can fit an oil cooler. Best get rid of the stock setup though, it's not very good.
I cant understand why toyota would not put an oil cooler on a boosted engine.. if anything, those need it much more than NA 4age's.

What you need to complete a stock setup:
-adapter plate (below oil filter)
-oil cooler (duh)
-some oil lines to connect everything with
-a return plug on your oilpan.

Not difficult to do, but it's a pressure bypass system, meaning it will actually work worse as the oil heats up an pressure starts dropping. It will be an improvement compared to no cooler at all though.

Otherwise, get yourself an aftermarket thermostatic bypass type sandwich plate and a decent oil cooler (stock rx7 cooler is nice too), and plumb it all in. This would be the better apporach if you want to take the engine a bit further than it is at the moment.
