VTT B58 “GC / GC-MID / GC+” Turbocharger Upgrades
Wheel Sizing / Power Support
Model Wheel Size (Comp/Turb) Stock Engine Power Range GC 54/55 Up to 600WHP GC-MID (TU ONLY) 54/60 Up to 650WHP GC+ 67/68 Up to 800WHP
Ready to take your B58 platform to the next level—without core charges, long waits, or compromising spool? VTT has you covered. Our 100% new casting B58 GC-Series turbochargers (GC, GC-MID, and GC+) retain the OE packaging advantages while removing the factory airflow limitations and weak internal architecture.
We start by keeping what BMW did right, then eliminate every bottleneck we found: the restrictive factory inlet, inefficient bearing housing oiling, small thrust assembly, and anything else holding the B58 back. Then we incorporate proprietary VTT improvements and cast everything at full OE-level quality.
The result? Serious B58 power made simple. GC turbos are direct bolt-on upgrades that retain all factory connections (oil, water, charge pipe, downpipe) while supporting 600WHP+ — with factory-like spool.
NOTE: The GC is Super Core ONLY, meaning no exhaust housing; this turbo plugs directly into your factory exhaust housing.

VTT x PFS EBS (External Brushless System) Fuel System
VTT, in collaboration with Performance Fueling Solutions (PFS), is proud to introduce the PFS EBS — External Brushless System.
The EBS is a fully stand-alone, next-generation brushless fuel system available in both platform-specific and universal fitments. Built around state-of-the-art Protec brushless pump technology, this system is capable of supporting up to 2,500 HP on ethanol-based fuels — and even more on gasoline or ethanol blends.
With its compact 15" x 10" footprint and ultra-lightweight construction, the PFS EBS is engineered for performance without compromise. The complete system — including pumps, surge tank, FPR, controllers, and wiring harness — weighs in at under 10 lbs (dry), thanks to a carbon fiber mounting plate and carefully chosen lightweight materials.

VTT-FAB B58 Factory Control EWG Top Mount Single Turbo kit
For BMW G-Series & Toyota A91 6-Port B58 Platforms
VTT-FAB is proud to offer the premiere top-mount single turbo system for the BMW G-Series and Toyota A91 B58 platforms. This kit is 100% made in the USA at our Hayward, CA facility, using only the highest-quality materials and components.
At the core is a hand-fabricated equal-length 321 stainless steel manifold with billet flanges, designed for maximum flow, durability, and that signature 6-into-1 turbo sound. The system is paired with our factory-controlled external wastegate setup, featuring a Turbosmart 60mm Straight Gate. This innovative design allows full external gate control through the OEM ECU — no additional boxes, MAC solenoids, or vacuum/boost lines required. Simply reuse your factory actuator with our adapter for seamless, plug-and-play control from 0 PSI all the way up to your turbo’s limits.
Unlike other kits, the VTT-FAB system uses no silicone couplers. Instead, we provide VTT-FAB HD clamps to eliminate the risk of blown boost hoses under extreme load.
⚠️ Important Notes:
-
Every VTT-FAB kit is built to order and cannot be canceled once fabrication begins. Please order carefully.
-
If your kit of choice is listed out of stock, email [email protected] for current build times.
-
Garrett turbo options are oil-cooled only (no water lines). This is perfectly fine for street and drag applications. For extended track/road-race use, we recommend adding water cooling
