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.

To construct a TTE400 N20, the folks at TTE change the original compressor and employ a far larger and more efficient billet 6+6 wheel and mill the compressor cover to the optimum gap to match the new compressor profile. Notice how they CNC mill the cover to have a smooth transition to the intake inlet, no big step to hinder airflow as you see on the competition's offerings. They replace the original exhaust turbine and CNC mill the turbine housing to install a larger 9 blade turbine for greater gas flow and lower backpressure.
