Mocal oil cooler & sandwitch plate ordered

[NoHachi]

If you run the oil through a cooler that is in series with the filter it will take forever to get oil temps up during cold nights and do more harm then good. Thermostatic valve to open and close the oil cooler seems like the best idea. When the oil gets too hot, the oilcooler valve opens and reroutes oil through the cooling element. You are right to assume that its not being filtered when this happens (no way to prevent that really, its a characteristic of almost all systems). As soon as oil temps drop, the valve closes and the oil runs normally through the filter again.

The water cooled system from the MR2 (the tube is a heat exchanger) is pretty nifty too. Water heats up quicker then oil so it helps get things up to temp. Max temp of water is 100degrees so it does help a bit with the cooling when things get hot. Probably not that much though. Would be a nice addition to any car if the pipe can be plumbed in easily into the AE86.
Don't see it fitting in easily though.
