Started to put together the cooling system for the car. Purchased some miscellaneous hoses with roughly the right length and shape for the top of the radiator to the thermostat and the bottom of the radiator to the engine block. The honda civic radiator has smaller hoses so will have to step down the larger miata size hoses so there are no leaks.
Will need to pick up a few more items for the system including a the thermo switch on the top of the thermostat. According to this site: http://www.miata.net/garage/CoolingSystemProblems.html the thermo switch on the thermostat controls the radiator fan, and will turn it on at 207 deg F . The Supercharger add on came with a 160 deg F thermostat, to help with engine pre-detonation. If the cooling system functions nicely, then I will not need the fan, but I have a feeling that by downsizing the radiator (civic) that I may want the fan running at lower temperatures that 207 deg F to keep everything cool.
After reading this article (http://www.tuneruniversity.com/blog/2012/04/low-temp-thermostats-whats-the-advantage/) on lower temp thermostats, it seems like it may not help the engine all that much, and what I really want to make sure of is that my radiator is up to the task and that my fan will kick in and help out the radiator enough.
Will probably have to get a overflow reservoir for the cooling system as well.
