Order controller and cooling system

I ordered the Zilla from www.evsource.com because they also offer a packaged cooling system. I was thinking of using the stock overflow tank and the heater core or a regular oil cooler from Kragen, but I would still have to get a pump and their kit was much cleaner and about the same price. The Zilla will take about 4 months to deliver, so it’s good to order it *way* in advance.
