MuchBoost TD05-20G/TD06-25G Upgraded Turbocharger with a Custom Billet Compressor Wheel and Enlarged Turbine Wheel. It is based on an original Turbocharger, which means that the installation is 100%P&P. The turbocharger is meant to work with Subaru Imprezas with the EJ 220-300HP engines.

The turbo delivers up to 218% power (260 extra HP) over the factory specs. It is a great choice for someone looking for a bit extra HP from their daily driver. MuchBoost turbo allows you to get more from your engine and enjoy it even more than you’ve been so far.

We have developed 2modification options that allow you to reach anywhere from 420HP to 480HP.
