VAG 1,8L 20VT Sidewinder Twinscroll Turbo Manifold
Description
Engineered specifically for high-output motorsport applications, this manifold utilizes a specialized top mount configuration to perfectly position your turbocharger for optimal engine bay packaging and serviceability. Our innovative engineering incorporates equal length piping in a true twinscroll configuration, pairing alternating cylinder pulses to completely eliminate exhaust gas interference. This optimized scavenging effect guarantees incredibly rapid boost response and smooth, linear power delivery across the entire RPM band.
To endure extreme exhaust gas temperatures (EGTs) without fracturing, this manifold is constructed from your choice of high-grade SS316 or SS321 stainless steel, assembled with flawless high-quality TIG weldings. The system anchors to the engine via a precision CNC-machined billet head flange that prevents warping under intense thermal stress. To match your exact power goals, the manifold can be configured with 42mm or 48mm heavy-wall piping and features a dedicated high-flow T4 twinscroll outlet flange along with dual provisions supporting 2x external wastegates for absolute boost stability.
- Twinscroll Split-Pulse Design: Separates exhaust ports into dual channels to isolate exhaust pulses, maximizing turbine efficiency and transient response.
- Dual Wastegate Runners: Equipped with precision-engineered provisions for 2x external wastegates to provide flawless high-boost control and prevent boost creep.
- Billet Head Flange: Ultra-thick CNC billet design offering superior sealing capacity and maximum resistance to high thermal cycling.
- Engine bay modifications may be required depending on your exact chassis configuration.
- Depending on your turbocharger size, custom modifications such as installing an aftermarket brake booster may be strictly necessary to ensure proper clearance.
