MHI TD03 BMW N54

IF YOU ARE UP TO THE METICULOUS JOB OF REPLACING A TURBO CARTRIDGE YOU CAN PURCHASE THESE READY TO INSTALL CHRA TO GET YOU BACK ON THE ROAD. WITH THE TURBOS OFF THE CAR WE RECOMMEND INSPECTING YOUR WASTE GATE FLAPPERS  AND MAKE SURE THEY ARE NOT TO LOOSE BEFORE RE-INSTALLING.

Direct OEM replacements with Upgraded TD04 Thrust assembly.
These are a direct replacement for the factory turbocharger. All brand new internals using the upgraded TD04 thrust assembly.
PLEASE NOTE: This is very important to be aware of. Replacement CHRA's DO NOT COME READY TO RUN. You must disassemble your old N54 turbochargers, and install the new CHRA's into your old housings. This can potentially be VERY difficult, damage to the new CHRA can occur very easily if care is not taken when performing the swap.
ALSO NOTE: These CHRA replacements WILL NOT help with any wastegate rattle, or worn watsgates, which can cause low boost conditions, sticky wastegates, etc. These are replacing ONLY the center section.
