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.

Introducing VTT-FAB Billet TIG Trailing Shields VTT-FAB is proud to announce our Billet TIG Trailing Shields, designed to set a new standard in the trailing shield market. We identified a gap where existing options were either too expensive or made from materials that degrade, melt, or fail when exposed to hot surfaces during welding. With this in mind, we took a fresh, innovative approach and developed two high-quality trailing shields to address these issues.
Product Highlights
- Premium Construction: Crafted from billet 6061-T6 aluminum and anodized in red for corrosion resistance and durability.
- Optimal Gas Coverage: Equipped with an internal diffuser and a finely calibrated screen to fully diffuse gas, ensuring optimal coverage for stronger, cleaner welds.
- Versatile Design: Two versions are available:
- Radiused Trailing Shield: Contoured to match 2.5"–5" tubing.
- Flat Trailing Shield: Ideal for flat surfaces and other specific welding needs.
- Universal Compatibility: Suitable for all materials and designed to attach directly to your TIG torch.
- Extremely light: With fittings only 2 Oz for the flat version, and 3 Oz for the radiused!
Innovative Features
- Continuous Argon Flow: Prevents contamination, resulting in cleaner, stronger welds—an essential for TIG welding.
- Swivel Quick Disconnect (QD): Each shield comes with a VTT-FAB Swivel QD Female Connector and a 1/4" Barbed Male Fitting (available in straight or 90-degree options).
- Ensures smooth, tangle-free operation as the swivel moves effortlessly with your hand.
- Allows for quick detachment if you choose not to run gas, enabling you to leave the shield attached to your torch with no line in seconds.

Are you building a single kit for the N54, N55, or S55 platform? The stock studs are usually a little bit short for most single-head flanges, and finding M7 studs is not easy. So we made our own longer studs to combat the issue. Made from 10.9 grade steel, and coated in black oxide, these are the perfect solution to the short stud problem. Sold individually so order the number you need. Stud details are as follows
- Overall length 47mm (stock 39mm)
- 3mm shoulder
- 6mm head which is 5mm hex
- 14mm short end
- 24mm long end (stock 15mm)
Dont forget our M7 copper lock nuts as well to complete the job - https://vargasturbo.com/product/vtt-fab-m7-copper-locking-exhaust-nuts/
