Fixing Mazda's crap cooling system design

Many people find they have trouble with overheating after installing a turbocharger on a miata. The system is already pretty stressed in its stock form, and the added heat of a turbo usually puts it over the edge. Thankfully, there are many ways to fix this! The fix can range from a cheap fix brewed up from a member that you can do your self to an expensive but pretty re route set sold by a few companies.

While many people just assume a larger radiator is the answer to cooling problems, many times its not. If the car is just street driven, then just a coolant re route should be fine. If its a track queen, then maybe a large radiator is necessary. An example of this is Marc at M-Tuned, his company is creating a re route kit, and when he installs it, hes even going to try running with a half sized radiator!

Of course proper under body shrouding should be done before anything else. make sure the bumper mouth - intercooler - condenser- radiator is sealed up to make sure all the airflow flows through them. An extractor hood or outlets under the car can improve this further, creating a pathway for air to quickly enter the coolers and exit. This not only helps cooling, but aerodynamics too!

So lets get at it!
