IPOSMotorsport IM500 B46/B48 Turbo Upgrade

Designed for racers and enthusiasts demanding the absolute highest power from their BMW B46 or B48 engines, the IM500 Turbo Upgradeby IPOSMotorsport is the biggest and most powerful turbocharger offered for the B4x platform.

If you want top-end power without compromise on OEM fitment, this turbo is your ultimate upgrade. While it introduces some additional spool lag compared to smaller turbos, the IM500 delivers unmatched top-end boost and power potential. It fits both Gen1 B4x and B4xTU enginesand can be installed on a stock motor, though Gen1 motors are recommended to be builtfor maximum performance and durability.

• Resized compressor housing (.57 AR) and exhaust housing (.64 AR)for optimized flow

• Optimized manifold exhaust pathfor better exhaust gas flow and efficiency

• Reuses OEM wastegatefor seamless integration

Important Notes:

• Lead time is typically 2-5 weeksdue to demand and production.

Recommended Use:

Perfect for racers and high-performance street builds who want maximum power outputand are willing to accept a slight spool delay. If faster spool and daily driveability are priorities, consider the IM450 turbo instead.
