Airwerks turbochargers are designed for the competitive motorsports market as well as drivers retrofitting a naturally aspirated engine or looking for a little more performance from a factory turbocharged car.

Engineered specifically for drag racing, pulling and road racing, AirWerks turbochargers have earned a reputation as robust, brute-force induction systems. Looking for a no-frills replacement? Want to upgrade your turbocharger? Working with limited space? BorgWarner’s AirWerks turbochargers are the perfect go-to product for many applications.

With a twin hydrodynamic journal bearing design, AirWerks turbochargers feature an effective high-pressure ratio compressor stage, extended-tip technology and a high-efficiency turbine stage. The configuration provides ultra-fast response and more than 70 PSI of boost.

This guys are hands down the best turbo specialist in South Florida. Well worth the 2 hours drive. Got my Perkins Marine turbo Remanufactured and all I can say is wow. From a rust bucket to a brand new looking turbo in 3 days exactly. Just as promised, and the best part is I saved over $1k compared to the cheapest price I could find. They just got a life long customer.
If you are looking for a true turbo specialist, give these guys a call. Highly recommend them!
