Muchboost ADU 2.2 Hybrid Upgraded Turbocharger with a High Flow Compressor Billet and Turbine Wheels. It is based on an original KKK (BorgWarner) turbocharger, which means that installation is 100% P&P. The turbocharger is meant to work with Audi RS2, S2, 200, snd S4 equipped with the 2.2 ADU/ABY/AAN/3B 220-315HP engines.

The turbo delivers great power characteristics and has something to offer for anyone that’s interested in gaining more power from their daily driver or trying to get maximum performance from their fun weekend car. You don’t have to worry about being taken over anymore. All of the upgrades listed below are based on a brand-new turbocharger!

We have developed 3 modification options that allow you to reach anywhere from 420HP to 550HP.

MuchBoost RS2 K24 420

Upgraded turbocharger with an estimated ~420HP at the crank. List of modifications:
