Oil cooler setups?

I'm trying to figure out the best way to setup an oil cooler setup. ATM, i have the stock 4age oil cooler setup which is a low pressure system that diverts via a therostatic plate attached to the block and then back to sump.
There is the option of including a remote filter setup so it'll look something like this:
The problem i have with both the factory setup and this high pressure one is that when the thermo opens, the oil bypasses the filter meaning you're just recirculating potentially dirty oil.
I was hoping to use one of these:
To setup something along the lines of this:
This way the oil will ALWAYS go through the filter 1st. Am i just being paranoid about the filter thing? I just don't like the idea of running unfiltered oil through my engine.
Eddie.

seems like the fix ... always filtered regardless of thermatic bypass.
who does such a kit if i may ask?

I'm not too sure if anyone actually does this in a full kit... i just made the setup through the research i did about oil coolers. I'm sure there would be someone that makes one like this though. My plan is to buy the stuff separately because i already have things like an oil cooler plate.

My thought is to get a proper aftermarket oil cooler that will cope with full flow and just run full flow to both filter and cooler. If it runs too cold in daily driving then just tape a piece of cardboard to the cooler to reduce airflow. Then take it off at the track.
An oil temp sensor is a good investment at this stage too as too cold oil is also bad.

This is what i've done, and it works quite well.

both Mocal and Permacool make nice thermostats..
i'll likely do that setup also.. seems noice. just means a bit more hassle when changing oil.

Fit a good sized full flow cooler, and if the oil is running too cold, then you're not putting your boot into it enough

Not trying to say that Big T is wrong, but is it confirmed that oil bypasses the filter when the thermostat opens? That would seem like a pretty major design flaw to me, especially for a factory setup.

I ran a remote filter & oil cooler setup on my 4AGTE, but without the thermostat. Its not a bad idea though (just its the most expensive part of the setup), as it helps to get the oil temp up quickly by bypassing the core until its needed.
Would there be any disadvantage though to revising that last diagram to put the filter AFTER the cooler & thermostat? Not that its very likely to have any shit come from the cooler, but for me it would be extra peace of mind 
All these parts are available from Motorsport Connections in Seven Hills (sydney). They do orders by phone/fax too.
One thing to note (as mrshin mentioned) is that if you go for a full flow cooler setup, you must have a decent aftermarket oil cooler with plenty of flow potential. I did try running a denso core commonly fitted to many jap cars, and it had enough restriction to drop 15psi oil pressure. Bad move

Remember that the sump oil comes up the middle and out the ring round the edge. The sandwich place just extends the center pipe.
The releif valve would prob become blocked over time if it was fed unfiltered oil

Are you trying to say a stock AE92 oil cooler wouldnt be up to task? remember im only using a stock 20v but they are known to get a bit hot on the track at times.

Yep, thats right. The AE92 cooler is only designed to flow the relatively small amount of bypass oil from the relief valve that would normally just go back into the sump, its a low pressure, low flow system. Running your full engine flow & pressure doesn't seem to work so well without a cooler designed for the task.
