Water to air intercooler on a KA

[Id-]

what wiring?

air/water is the best setup possible; but most people dont have the patience nor the know-how to set it up

it takes a air/water core (can make one from a air/air core actually), coolant tank, two lines, small electric water pump (can get a good brand for like $50, some stock fuel pumps work too, gotta research), and a cheap oil/water cooler from some junkyard car (or from autoparts place)..

basically the pump pulls water from the bottom of the tank through the line, pushes it into the core, it comes out the other side and is pushed by the pressure into the oil cooler, it comes out and is drained into the tank... pretty simple...
whats really nice is getting ice water in there
this setup works best on a pressurized setup, you can also place the cooler BEFORE the core and get away with not being pressurized

only wiring involved is the pump itself, which is very simple; just run it off the ignition power on the ecu
