Summit’s Ford 300 I6 Turbo kits turn you into 500-horsepower thoroughbreds

You can say a lot about Ford’s 300-cubic-inch inline-six. For starters, you could say it’s insanely durable and laughably simple, which is exactly what you want in a workhorse. But you can’t really say it’s a strength, at least in stock form. Fortunately, Summit Racing sells some kits that remedy the problem by providing everything you need to boost your cast iron engine to high numbers.

This is an excellent compilation of parts that will allow you to go as wild or mild as you want, for as little or as much money as you want. I know a lot of people like to make their own turbo setup, maybe one with a smaller supercharger for a flatter curve, and still benefit from the top-end kit. Or maybe someone has already done the hard work of building the short block and haven’t messed with turbines before, so this kit suits them better. Or maybe they just want to buy it for $7,783.09 and not worry about anything else.

Either way, these settings could be your ticket to embarrassing V8s, so spend accordingly.
