BMW custom-installation planning

Universal does not mean bolt-on. Check the manifold flange, turbine housing A/R, wastegate arrangement, compressor inlet and outlet, oil supply and drain, applicable water connections, engine-bay clearance, intake and exhaust fabrication, supporting fuel system and ECU calibration. No BMW chassis or engine fitment is claimed for this universal product.

The supplier rating is a turbo sizing reference, not a guaranteed engine or wheel-power result. Output depends on the engine, fuel, boost, supporting components and calibration. Confirm suitability and applicable road-use requirements for the finished vehicle.

M LAB workshop support

Contact M LAB by Boost & Tune in Melbourne for configuration review and a separate installation or tuning quotation. Confirm supply availability and dispatch timing for the exact configuration before ordering.
