8 Best Subaru BRZ Turbo Kits? Massive power gains.

While the BRZ is a popular affordable fun sports car, it definitely could use some extra power. Its FA20 engine is naturally aspirated, while the WRX gets a turbo variant of the same engine, so what better way to go faster than by adding a turbo? A supercharger kit is another great option for forced induction, but with a turbo, it's possible to build more boost and make more low end power.

While the car well deservedly has received a lot of hype, with its great styling, its low weight of under 2800 pounds, and its well-balanced chassis, the stock engine only delivers around 200 horsepower. Compared to many cars, that's a decent number, but this is meant to be a sports car! Fortunately, there are many manufacturers that offer complete kits with everything you need to install a turbo on your BRZ.

We've reviewed the most popular to help you decide on the best Subaru BRZ turbo kit. These turbo kits also work with the Scion FRS and Toyota 86 since these cars are essentially rebranded versions of Subaru's BRZ.
