This is where you will find upgraded turbochargers that make more boost and can handle higher power levels. If your stock turbos are worn, it is a perfect time to look into upgrading the factory snails with something larger.
Stop letting your N20's factory turbo strangle your lap times and choke out your top-end speed. The Pure Turbos Pure400 EWG upgrade is the track-proven weapon your four-cylinder BMW has been begging for. This isn't a simple rebuilt unit, it is a brand-new aftermarket housing packed with performance internals designed to take a beating and keep delivering. Featuring a custom billet compressor wheel, a high-flow turbine wheel for rapid exhaust scavenging, and an upgraded CHRA that is VSR-balanced to perfection, the Pure400 is built for those who push their cars to the limit. It drops right into place, replacing your stock turbocharger, and provides a reliable 300+ wheel horsepower, with supporting modifications.
