Ready to take your BMW G8X M3/4, or F9X XM3-4  to the next level?  Don’t want to deal with core charges, long lead times, or restrictive factory housings? Look no further! VTT has you covered with our 100% new casting  “GC” turbocharger upgrade. We start by keeping the great design elements of the factory BMW turbochargers and removing the not-so-great ones such as the small factory inlet area, bearing housing oil structure, thrust bearing, and anything else we saw that could be improved upon.  With the basics covered, we stepped it up a level by adding proprietary VTT changes and finished off by having all these parts cast to OE quality.  What this means for you is serious power made easy; GCs are a drop-in turbocharger upgrade that supports  800-950WHP while maintaining near factory spool and all factory connections including oil, water, downpipe, and charge pipe. These are record-breaking turbochargers that hold all the G8X records fo ET, and Trap speed as of 7/24/22

Key Design Elements:

  • All new castings with factory restrictions are removed. No oversized wheels stuffed into factory housings here!
  • TWIN-SCROLL 310 Stainless Steel Turbine housing for the ultimate in heat, and corrosion resistance
  • GC 52mm – GC+ 54mm G25 Spec 9 blade Superalloy Mar-M 246 turbine wheel with the latest aero technology for increased flow while maximizing spool
  • GC 58mm – GC+ 67mm 9 blade “point-milled” compressor wheels with the latest aero technology to maximize flow while virtually eliminating surge
  • Direct connection to ALL factory lines including oil, water, downpipe, and factory charge pipe
  • Redesigned, and improved internal components including bearing housing oiling, and an upgraded thrust bearing
  • NO CORE CHARGES. The new unit is sold to you outright. Keep your old unit in case you ever want to go back to stock. Or sell it to recoup your investment -it’s up to you!
  • No long lead times; once fully released production units will be on the shelf for same to next day shipping (please inquire about stock levels when ordering)
  • 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 – VTT  set “GC/GC+” turbochargers
  • 1- VTT set of GC/GC+ Silicone intakes

As with any turbocharger upgrade it should be coupled with complimenting upgrades such as fuel system upgrades, intake, downpipe, intercooler, tune, etc. While you will see gains going from stock turbo to a GC with no other changes, to realize the full potential of the upgrade other parts/tune must be added.
