What's the best radiator set up?, Most efficient set up for overall cooling, airflow ect... Options

[Fastcruisin914]

I am doing a Subaru conversion, and am looking for the best proven cooling system.

I have seen the Renegade Hybrid kit, worth the cost??? I have also seen some refer to Desert hybrid, are they still even around or doing 914 radiator kits, and if so are they any good?

So many factors like, front trunk radiator set ups, or rear truck set ups?

The angle of the radiator in the front truck, straight up against the front saving trunk space, or sitting back further and angled, or even in the floor of the trunk?

Also with the air flow, big cuts in the wheel wells, or many holes in the wheel wells, or venting through the trunk floor, or through the hood with the air going up, what is the best way for the air flow without taking from the vehicle structurally?

Pictures would be nice, or even something that may show the step by step process from start to finish with the cooling system install/fabrication.

Here are some pictures I took today.

The holes in the shroud are new... as a test top see if it made a difference. I think it did because in the past (with no holey shroud), it did not matter how cold it was outside; the temp would always go to 200 and beyond (have a 160 t-stat with bleed holes drilled and the fan is set to turn on at 180). After cutting the holes in the shroud, the temp would stay at around 180 (acceptable) although it was when it was cooler outside. Now in this 100 degree weather... it does not matter... it still get to 200 and beyond).

The extra fans are from a Toyota 4-Runner AC condenser units and were mounted there temporarily to see if they made any difference in assisting the main fan exhaust air from the front area (they were wired to push air out). They did not work.

Also; my temp sensor is mounted in a port right next to the t-stat/intake manifold.
