In the last episode of my '76 Mazda Cosmo restoration, the basic components of the water to air intercooler system were laid out along with the considerable amount of fabrication needed to build the throttle body inlet, intercooler piping and water tank. As well as mount the heat exchanger and BOV. In part 35, we finish up the water to air intercooler installation by taking care of mounting the pump, plumbing all the water lines and wiring up the system. Additionally support brackets are built to support the piping. Lack of space meant I had to get creative with pump position after accidentally creating a clearance issue with the water fittings. However once mounted I was very happy with pump position and the plumbing was straightforward. Included in this episode: Cutting/grinding/drilling aluminium, making aluminium brackets, assembling AN house and fittings, wiring relay to spare Megasquirt output, adding temperature sensor to Megasquirt analog input, plumbing air to water intercooler with tank and pump, TIG welding brackets.
