yea I wish someone made a rear bumper like that for sale to the public.
I have tech2. can i make 1 option with it ?I recommend SPAL fans for several reasons:
1. they are sealed so they last a good amount of time,
2. have different versions from normal, long life and very long life
3. They produce fans for GM production vehicles
Depending on the size of the fan check this chart:
http://www.spalautomotive.com/eng/products/axial_12.aspx
Get the highest amp fan in that size for best performance and if you want to compare different fans check the cfm rating at different pressures (for your setup without condensor look for cfm at 0.2 static pressure)
I also recommend you get a Long life or very long life fan (on ebay)
Long life will have a LL code while very long life will be VLL (approx 20000 hours)
As to fan control, you have several options,
1. Difficult option, pcm controlled (only need hptuners and 1 wire from pcm to relay)
2. Easy option, coolant sensor plugged in engine block similar to how the stock sensor is plugged in (rear of passenger side of the engine for new sensor, stock sensor is in the front driver side of the engine block)
3. Normal option, get adapter into the radiator hose and plug sensor into adapter
4. Normal option, drill into radiator and put the sensor.
Option 1 and 2 are most accurate, 4 is slighrly less accurate and option 3 depends on where you drill the sensor (top or bottom)
Finally, the SPAL HO fans are really loud so dont think of them unless you dont care.
