Turbo Upgrade Kits for Audi, Volkswagen VW, BMW & Porsche Vehicles

The people you know may not function better under pressure, but your engine does. Forced induction extracts more horsepower and torque from your engine by compressing air that delivers more oxygen to the combustion chambers. The aftermarket turbo upgrade kits that USP Motorsports sells generate higher performance than stock turbochargers do, from the low end to high.

Below you’ll find turbos, turbocharging accessories, turbo manifolds, stronger pistons, turbo upgrade kits, conversion systems, supercharger systems, high-flow exhaust manifolds, and other forced induction enhancements. Our inventory comes from top suppliers, including 034 Motorsport, APR, Assembled by USP, ATP Turbo, BorgWarner, Forge, Integrated Engineering, OEM Audi / VW, Spulen, TiAL and USP Motorsports... more

More oxygen in the combustion chambers means more power — more than 450 HP in some applications. Today’s turbos spool up quickly, delivering a broad power band evident almost instantaneously when you apply more throttle, with gobs of low-end torque.

Most of the turbos for sale by USP are stealthy: Not just universal turbochargers, they look like an Audi or VW stock unit from above, and they often retain stock heat shields and oil feed lines, sometimes with a step-down fitting. You can buy a complete turbocharger kit, with every part you need to install your new unit. And we have awesome Stage III turbo kits, some that the manufacturer requires us to send only to an authorized installer.

If you buy less than a full installation kit, any forced induction accessory you may need, such as inlet hoses and pipes, compressor outlet hoses and coolant lines, can be purchased from USP. We’ll help you get the right parts for your ride.

The turbos, turbo kits or turbo parts in our inventory, depending on brand and model, fit the VW GTI and Jetta, 1.8T and 2.0T engines, both FSI and TSI, and Golf R; Audis with 1.8T, 2.0T or 2.7T engines, including the A3, S3, RS3, A4, S4, A5, A7, RS7 and R8; and Porsche 993, 996 and 997; and more.

To get the most from your turbo upgrade, explore ECU software, which helps you set your vehicle to its optimal tune; exhaust systems and parts, including downpipes and test pipes, catback exhausts and free-flow catted exhausts; and intercoolers, including boost hoses and outlet pipes and hoses, that lower the temperature of the pressurized air going to your engine. Some especially powerful turbos require upgraded intercoolers.
