His radiators are the GM Evaporator cores plumbed in series with AN-12
fitting and hose.  His oil cooler is the stock mazda oil cooler using AN-10
fittings and hose.  He also uses the stock Mazda 13B thermostat (that plugs
the 1/2" hole in the water pump).  Temperatues climb as high as 240F on the
oil and 220F on the coolant measured at oil inlet and water pump thermostat
housing.

I thought Tracy plumbed the cores in parallel -- series would lower the flow
rate through all the plumbing.
