As you know my head has cracked- yes long ago I know

I would like to find out what parts I need to get, to fit the intercooler off the '96 and later Prados or intercooled Hilux's etc.
The other option would be the water to air intercoolers and how do they perform in comparison. Obviously the air to air will only work effectively at moderate or above speeds. What are the downfalls of the water to air variety?
Does anyone know if the fuel injector pumps, injectors or ECU's or anything else differ between the non-intercooled and the intercooled versions of this motor?
Thanks in advance
Cheers John
