Clear BMW chassis

Please ensure your correct model is selected

If more boost and reliability are your goals choose from one of our BMW turbo upgrades. Our turbo upgrades range from stock turbos rebuilt with stronger internals to all-new, ground-up turbo upgrades. BMW turbos such as the N54 are capable of really impressive power numbers on stock engine internals but the factory turbos lack the precise tolerances and reliability that an upgraded unit will deliver. In other words, the stock turbos can only do so much and if big power (>400whp) is your goal a turbo upgrade must be in your plans. Our partners are leading experts in turbo technology and upgrades. Each Stage has been professionally developed and tested. Additional upgrades and tuning may be, or is, required. Contact us for more details on tuning options.

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.

The TTE550 for the N55 motor. Still keeping the original turbocharger the compressor wheel is exchanged for a TTE milled aluminum wheel with state-of-the-art geometry, 7+7 blade so producing extra power. Equally, The Turbo Engineers change the original exhaust turbine for a far larger but very lightweight 9-blade TTE-designed turbine for lower exhaust gas backpressure giving greater performance, yet still giving a good spool response. The Turbo Engineers also fitted a TTE motorsport upgrade bearing system for durability. Equilibrium Precisely balancing the turbochargers is a key critical factor to becoming a TTE upgrade unit as longevity and performance are paramount. Good balance improves acoustics also. Subsequently, great care is taken with all TTE turbochargers to achieving balance standards. Firstly, parts are balanced at slow speeds up to 2800RPM in multiple planes using a single parts machine, then components are assembled and the CHRA are dynamically balanced, but this time depending on the application at up to 250,000 RPM in multiple planes using an in-house VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM. Each turbocharger is supplied with a serial-numbered balance test result document.

TTE580 is the very latest hybrid performance upgrade turbocharger based on the Original turbocharger for the BMW B58 inline-six-cylinder turbocharged engine. Superfast spool and response with extra power. We feel this is the best performing 550+hp hybrid. Engineered & Enhanced To construct a TTE580 The Turbo Engineers change the original compressor and employ a far larger and more efficient billet wheel with extended tip technology and mill the compressor cover to the optimum gap to match the new compressor profile. The Turbo Engineers change the Original exhaust turbine for a larger 9-blade high-flow item to lower EGT and raise the power potential but maintain a great boost response profile. Equilibrium Precisely balancing the turbochargers is a key critical factor to becoming a TTE upgrade unit as longevity and performance are paramount. Good balance improves acoustics also. Subsequently, great care is taken with all TTE turbochargers to achieving balance standards. Firstly, parts are balanced at slow speeds up to 2800RPM in multiple planes using a single parts machine, then components are assembled and the CHRA are dynamically balanced, but this time depending on the application at up to 250,000 RPM in multiple planes using an in-house VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM.
