RB Turbos are complete OEM upgraded replacements. They are shipped to you complete as if you had bought new OEM Turbochargers from BMW.

The installation of turbo hardware will require the use of some new gaskets, seals, and other supplies for a quality install. As a nicety I have provided a spreadsheet illustrating the components you should consider for installation, there are several footnotes so please pay close attention to that detail. Your local performance shop will appreciate you sharing this with them, and you DIY guys definitely will benefit as well. If you have a cooperative and understanding BMW service center who will be doing your install, they likely will not need this information.

RB Turbo provides hardware only and does not offer tuning equipment nor support. However we have worked with the biggest players in the N54 tuning market and are confident in each and every one of their abilities to extract substantial gains from our hardware (see below).

Installation Notes:

  1. Do not run low volume flow oil Catch Cans with the upgraded turbos. We recommend the BMS Oil Catch Can as it is an high volume flow design and does not compromise the PCV systems ability to perform its function. We are not aware of another OCC that flows as well at this time. Also make sure existing PCV system check valves are in good condition and/or replace.

  2. Remove the oils FEEDs and Drains and clean thoroughly with compressed air and solvent/brake parts cleaner (replace lines if any debris can not be cleaned or there is uncertainty in condition).

  3. RB Turbos are hand built on a limited batch production run basis. Although RB Turbos can be ready to ship at time of payment there is also potential that they are not ready for immediate shipment. Please expect less than 6 weeks until your product is shipped. If you are in dire need of turbo replacements and can not wait please contact us so we can accurately discuss our place in the production cycle and/or perhaps attempt to expedite your shipment to meet your needs.

  4. Leave the plugs in the turbos oil holes until you are ready to install the oil lines to minimize chance of debris falling in and damaging turbos.

  5. Make sure there are no kinks in the oil lines after assembly (the original lines seem to be better formed to the car and install better).

  6. Use only new oil to break in RB turbos, use BMW approved oils for this application. Try to maintain use of the exact oil the engine has always utilized.

  7. Try to crank over the engine a few times without starting to prime some oil through the turbos.

  8. Make sure all intercooler hosing is fastened well and not leaking, boost leaks are not good for turbos and high boost can make small leaks larger or turn what was no leaks prior into some leaks (induction pressure testing recommended).

  9. Make sure the diverter valves are adjusted properly and/or not leaking.

  10. Use the provided custom coolant line spacers on each turbos' lower coolant line. The top coolant line installs first, then the lower last with spacer. There are two spacers taped to one of the turbo bags. DO NOT throw the bags away without first locating these spacers.

  11. Do not over-tighten or force sockets on the coolant line fastening nut, stripping the preinstalled stud may occur. Use a 10mm wrench and tighten lightly.
