Description
VTT is hitting the ground running in 2023 with the F8X platforms, proudly introducing our "GCMAX" evolution of the insanely popular and record-holding GC Series of S55 turbocharger upgrades. We took what we learned from those and elevated them to the next level! By increasing all the internal flow channels, optimizing AR ratios, maxing out the inlet size at 2.5″, and increasing the compressor wheel to 67mm, we have significantly enhanced the performance capabilities.
Key Design Elements
- New Castings: Larger flow channels, optimized AR ratios, and improved aero over current GC/GC+ housings.
- Material Excellence: 310 stainless steel turbine housing for superior heat and corrosion resistance.
- Advanced Turbine Wheel: 54mm G25 spec 9-blade superalloy Mar-M 246 turbine wheel with cutting-edge aero technology for increased flow and faster spool.
- High-Performance Compressor Wheel: 67mm 9-blade "point-milled" compressor wheel with the latest aero technology to maximize flow while virtually eliminating surge.
- Direct Factory Connection: Seamless connection to all factory lines, including oil, water, downpipe, and factory charge pipe.
- Redesigned Internal Components: Improved internal components, including bearing housing oiling and an upgraded thrust bearing.
- No Core Charges: Sold outright with no core charges. Keep your old unit or sell it to recoup your investment.
- Fast Shipping: No long lead times; production units will be on the shelf for same to next-day shipping (please inquire about stock levels when ordering).
- Comprehensive Warranty: Full 12-month unlimited mileage, no-hassle warranty. If you have an issue, we will replace the unit no questions asked.
Turbocharger Purchase Includes
- 1 set of VTT "GCMAX" turbochargers
- 1 set of VTT "GCMAX" silicone intakes
Performance and Compatibility
This setup is designed to support power levels up to 1000WHP, making it the ultimate choice for both stock and built motors. The GCMAX setup has already achieved impressive performance figures, such as going 9.44@146 in the G80 with a completely stock motor and drivetrain. This bolt-on solution is designed to offer big power without the hassle of single turbo conversions or the lag and complexity of other setups.
Fitment

- 3 Series: F80 M3 (04/2012 — 06/2015), F80 M3 LCI (01/2015 — 10/2018)
- 4 Series: F82 M4 (02/2013 — 02/2017), F82 M4 LCI (05/2016 — 12/2019), F83 M4 (06/2013 — 02/2017), F83 M4 LCI (05/2016 — 12/2019)
Additional Information
As with any turbocharger upgrade, it is recommended to couple the GCMAX with complementing upgrades such as a fuel system upgrade, intake, downpipe, intercooler, and tune to realize the full potential of the upgrade.
Vargas Turbo Disclaimer:
Vargas turbo kits are built to order and typically take 2-4 weeks to ship. Cancellations for any reason before 7 weeks will result in a 20% fee. Once a turbo is built, it will ship within 2 business days. Cancellation of any turbo after it has been built will result in a 50% fee. The same applies to all turbo returns, except for warranty and defect claims, where no fee will be applied. Custom items, such as coated parts, any VTT-FAB single turbo kits, and custom driveshafts, will also incur a 50% restocking fee.
