WHP Level supported (with proper fuel, upgrades, and tuning) Stock-850WHP

VTT is proud to announce an All-new VTT GC redesign for 2021! The latest in our line of N54 VTT “GC” turbochargers. The GC “F-RB” or Full-Rebrand.

This is an all-new take on the VTT N54 “GC” turbocharger, using 100% new parts throughout that is pure performance. Some of the new groundbreaking features include: All turbine side parts are now fully cast from 310 Stainless Steel for increased temperature resistance, and ultimate corrosion resistance. We also fully redesigned the turbine housing -the F-RBs have a much larger volute as well as a proprietary AR which will dramatically increase flow capacity, helping to eliminate stress on the turbine wheel. Fully redesigned compressor housings which now include V-band OR Hose Barb connection options (while our current stock of hose barb connections last). The CHRA’s are redesigned with new compressor wheels, bullet nuts, and better internal parts. These are new turbochargers from the compressor housing to the bearing housing, to the turbine housing. WeEngineered them to fit in the stock N54 location but provide the full flow of a much larger turbo -the F-RB’s outflow the GCV2.0’s by a significant margin.

With this all-new design, there is no other 850WHP capable turbocharger option on the market single or twins that can match the spool, ease of fitment, power, reliability, OR price of our GC “F-RB”  turbochargers!

GC F-RB turbocharger Features:

• Turbine housing cast from 310 Stainless Steel for the ultimate in temperature and corrosion resistance
• Turbine Manifold cast from 310 Stainless Steel for the ultimate in temperature and corrosion resistance
• Redesigned Turbine housing with an increased volume and AR size for improved flow over V2 GCs
• Mar-M246: Every set of F-RB Turbochargers comes with a Mar-M26 Superalloy turbine wheel for unmatched durability
• Re-designed compressor housings with the choice of V-Band or Hose Barb
• Upgraded Internals: Every set of stage F-RB turbos comes with a performance upgraded thrust, as well as upgraded internals to extend the life of the turbochargers.
• Anodized 9-blade “Hi-Flow” Billet Compressor wheels are used to maximize flow per shaft revolution and help eliminate surge
• We also offer 2000-degree ceramic coating for the ultimate in under hood heat reduction, and to help aid in spool! Please choose from the options if you want your turbo coated!
• All sizes utilize the same 52x46mm turbine wheel for increased flow

The “GC” F-RB comes in 3 sizes to meet all Power/Spool needs.

• F-RB+ 63x46mm Anodized Gold – 10-15% flow increase over Standard Billet GC Wheel Rated at 850WHP – Very good spool
• F-RB – 58x46mm Black Anodized wheel Rated at 800WHP – Slightly better spool than the GC+
• F-RB Lite – 58×43.3MM Purple Anodized Rated at 750WHP – Very close to the stock spool

VTT Inlet, AND/OR outlet bundle: The GC F-RB turbochargers work perfectly with our very own VTT 2″ inlets, and VTT aluminum outlet, and were designed to be used with these pieces. If you already have inlets or want to use another inlet brand that is not a problem, simply do not add them to the dropdown. These turbochargers will work with the stock outlet, any V-band outlet, or our GC Barbed outlet if that option is chosen.

Note: If you remove the inlet options, and do not have these items, you will not be able to install the turbos, as the stock inlets will not fit the new turbos.

We always suggest the use of an aluminum aftermarket charge pipe, and BOV combo, with upgraded turbos. Please see our BOV article for proper installation to avoid compressor surges!

Install package price is for turbo installation only, added parts such as inlets, fuel system parts, etc. will be additional labor.

*Please choose if you need BOV inlets or DV inlets from the options.

(Please specify the vehicle model when ordering. Currently, we have kits  for all models.)

We also always recommend upgrading your PCV system at the time of turbo upgrade or replacement, as the stock valve/system can be worn. This means it can stop functioning to its full potential, causing oiling issues with your BMW. This upgraded valve not only replaces the worn stock valve it is also much stronger and will help eliminate any future PCV issues. We have many PCV options available including our catch can, and aluminum valve cover options.

Engine oil choice with upgraded turbochargers is a very important aspect for longevity, we only recommend 40W oils and higher, with high Zinc, and Phosphorus content, for high shear strength.
