Description
For the racing enthusiast or those just looking for the best, the DINAN BIG TURBO is the ultimate upgrade to fully maximize the power output of your BMW 'F' Chassis N55 engine. By increasing the size of the compressor wheel inside the turbocharger, this upgrade allows approximately 30% greater flow compared to the stock unit. The result is the ability to achieve additional boost pressures at higher engine speeds while retaining efficiency.
Special Note: Installation times vary depending on application:
F30 335i RWD - 5.0 hrs
F30 335i xDrive - 9.9 hrs
Unlike standard rebuilds, the DINAN BIG TURBO consists of brand new units with a custom cast, upgraded stock turbine, and an enhanced thrust system. These features ensure reliable and prolonged life, providing peace of mind for high-performance driving. To unlock the maximum advertised power gains, pairing the big turbos with DINANTRONICS Stage 4 and Dinan's intercooler is recommended, along with considering upgrades to the exhaust and intake systems.
Benefits of the DINAN BIG TURBO for the BMW 'F' Chassis N55 Engine include a hassle-free upgrade process with no core charge or return required. The turbo assembly is compatible with mechanical/vacuum wastegate vehicles only. With the larger billet compressor/impeller wheel, you can experience approximately 30% greater flow compared to the stock unit, enabling additional boost while maintaining efficiency. The brand new stock turbine ensures optimal performance.
When combined with other Dinan Performance upgrades, such as the MPPK (M Performance Power Kit) and automatic transmission, the DINAN BIG TURBO can achieve peak power of 428 HP at 5500 RPM and 443 ft-lbs of torque at 4500 RPM. The maximum gain is an impressive 122 HP at 6000 RPM and 107 ft-lbs of torque at 6000 RPM (data based on F30 335i MWG). Please note that different variants may produce varying results.
Installation of the DINAN BIG TURBO is made easier and more cost-effective with detailed instructions provided by Dinan. The procedure is quicker than BMW's turbo replacement process, saving you both money and time at the shop. The package includes all necessary o-rings and gaskets for a complete installation on a rear-wheel-drive (RWD) vehicle. For installation on an xDrive vehicle, additional installation hardware (Dinan P/N D313-0117) is required.
With the DINAN BIG TURBO, you can enjoy the peace of mind of a factory-matching new car warranty (4yr/50k) when the system is run in Dinan specification. Additionally, this upgrade is 50 State Emissions legal, compliant with CARB EO # D-176-49, ensuring its legality for use across the United States.
