BMW B48 Turbo Upgrade - Up to 550bhp

As used on our B46 race cars and B48 engine packages.

This turbocharger features nearly factory fitment. It has a larger cast exhaust manifold to allow increased flow. 

48mm Version good for 390whp

54mm version good for 460whp

The turbo core has the same sizing specs as the Garrett G25-550 or G25-660.  It has a ceramic ball bearing cartridge and the plumbing to match the stock B48D ( 2020-2024 G20 330i and similar) oil and coolant hoses. We have modified it further so it bolts right in and all you need is to make an intake.

• Features a 48/60mm or 54/67mm Compressor Wheel with 0.57 AR Housing
• 49/54mm Turbine with 0.64 AR Housing
• Good for 390whp with 48mm version or 460whp with 54mm version. Power is very dependent on fuel and other engine factors. Ethanol is generally required to make the stated numbers.
• 2.75" Inlet requires use of aftermarket or modified intake but allows for greater flow than stock housing.
• Anti-surge inlet housing. 
• Depending on load can make peak torque around 2800rpm.
