More Turbo for BMW F83
When it comes to turbo upgrades for the BMW F83 M4, enthusiasts have several proven options that deliver serious power gains while maintaining street drivability. The S55 engine responds exceptionally well to upgraded turbos, with the most popular bolt-on option being the Pure Turbos Stage 1 and Stage 2 PURE600 or PURE700 upgrades, which retain the OEM turbo housings while fitting billet compressor wheels for significantly improved airflow and spool characteristics. Vargas Turbo Technologies also offers highly regarded Stage 1 and Stage 2 billet wheel upgrades that pair beautifully with supporting bolt-ons. For those chasing bigger numbers, full turbo replacements like the Precision Turbo or Garrett drop-in units push well beyond 700 wheel horsepower on E85 fueling. It's critical to remember that the S55's charge pipe system, particularly the OEM plastic charge pipes, are a known weak point that must be addressed with upgraded aluminum units from BMS or Mishimoto before stressing the system further.
Always upgrade your fueling system, intercooler, and engine management tune simultaneously with any turbo work. Pushing a larger turbo on stock injectors and a stock DME tune is a fast way to damage internals. Work with a reputable tuner experienced specifically with the S55 platform to dial in proper AFR targets and boost curves.
