*Special note – CarBahn Stage 2 software for the F-series M5/M6 requires this turbocharger upgrade. Core charges may apply.

CarBahn Autoworks is excited to present the Pure Turbos Stage 1 turbocharger upgrade system for the F10/13/12/06 M5/M6. Pure Turbos represents a premier name in the turbocharger market at a great price point.

Pure Stage 1 turbochargers are rebuilt with a larger compressor wheel. The turbo upgrade makes the turbocharger more efficient at higher volumes. This reduces charge air temperature at high RPM. The reduction in temperature means we can run more boost safely.

When paired with the CarBahn Stage 2 engine software, the end result is a car that not only delivers a massive amount of performance and power, but does so in a predictable way that enhances the driving experience without breaking the drivetrain.

Features and benefits of the Pure Turbos Stage 1 turbocharger upgrade:

Upgraded billet compressor wheel
Heavy duty large pad upgrade thrust
CNC machined
High Speed VSR balanced

For the racing enthusiast or those just looking for the best, this is the ultimate upgrade to fully maximize the power output of your EWG N55engine. The compressor wheel inside theturbochargerisincreased in size allowing ~30% greater flow thusenabling additional boost pressures at higher engine speeds while retaining efficiency. These are fully cast turbos that are manufacturedto our specifications along with anupgraded thrust system over the stock turboto ensure reliable and prolonged life. In order to attain maximum advertised power gains these big turbos will need to be paired with Carbahn’s smooth power flashas well as our intercoolerto fully regulate the boost increase and deliver a polished product.

Benefits of the Carbahn High Performance Turbo for the EWG N55 Engine:

–Fully cast turbo that is manufactured to Carbahn specifications with an upgraded thrust system thereby avoiding lengthy turnaround times caused by a core exchange program.
–Larger billet compressor/impeller wheel that allows ~30% greater flow over stock which thenenablesadditional boost to be realizedwhile retaining efficiency.
– Turbo assembly is compatible with electric wastegate vehicles only. Use in conjuntion with CBN55-1001H (N55 Turbo Hardware Kit)
–Installation instructions detail a procedure which is quicker than BMW’s turbo replacement procedure saving the end-user money and time at the shop (Applicable to RWD vehicles only).

*Special note CarBahn Stage 3 software for the F-series M2C, M3, M4 requires this turbocharger upgrade. 

CarBahn turbocharger upgrade system for the F-series M2C, M3, M4 are new not rebuilt units. They come with larger compressor wheel and housings, Larger turbine wheel and housing and a new high-performance exhaust manifold casting. The turbo upgrade makes the turbocharger more efficient at higher volumes. This reduces charge air temperature at high RPM. The reduction in temperature means we can run more boost safely. This superior design has more flow and less lag than most other high performance turbochargers on the market.  When paired with the CarBahn Stage 3 engine software, the end result is a car that not only delivers a massive amount of performance and power, but does so in a predictable way that enhances the driving experience without breaking the drivetrain.

Estimated Installation Time: 17 hours
