Audi 1,8T Turbokrümmer T3 Flansch + 38 mm WG

VW/Audi 1.8T Turbo Manifold – T3 Flange – Nickel Cast – 38 mm Wastegate Port

This high-performance nickel-cast turbo manifold is purpose-built for VW and Audi 1.8T 20V engines. Featuring a standard T3 turbo flange and an integrated 38 mm external wastegate port, it's ready for serious turbo upgrades with GT30, GT35, T3/T4 turbos and more.

The robust nickel cast construction ensures exceptional heat resistance and durability under high-load conditions. Optimized runner geometry provides smooth, equal-length flow paths to minimize turbulence and ensure fast spool-up and even cylinder distribution. Perfect for applications with high boost and extended full-throttle usage.

Key Features:

• Engine compatibility: VW/Audi 1.8T 20V (AEB, AGU, BAM, ARY, APP, etc.)
• Flange: Standard T3 (4-bolt pattern)
• Wastegate: 38 mm external port (e.g., Tial, Turbosmart WG38)
• Material: Nickel cast – highly heat-resistant and pressure-proof
• Position: Top-mount or low-mount (setup dependent)
• Turbo compatibility: GT30, GT35, T3/T4 hybrids and similar

Benefits:

• Thermal stability above 1000 °C
• Thick-walled casting – no cracking or warping
• Perfect match for 1.8T OEM heads
• Even flow distribution – faster spool and better response
• Clean solution for external wastegate-only setups
• Ideal for big turbo conversions with no compromise

Applications:

• Custom turbo builds with external WG
• Track tools, race cars, drag setups
• Big turbo street performance upgrades
• GT30/GT35-based 1.8T builds

Recommendation: Use thermal wrap or ceramic coating for heat management. A flex joint in the downpipe is highly recommended to relieve stress from thermal expansion.

Conclusion: This nickel-cast T3 manifold with 38 mm WG port is made for enthusiasts and professionals pushing their 1.8T engine to the next level. Strong, heatproof, reliable – built to perform.
