Technical Description

Is your MSM blowing blue smoke? Precision oil control starts here. The IHI VJ35 turbocharger found on the 2004-2005 Mazdaspeed Miata is highly sensitive to oil pressure. Excessive pressure can overwhelm the internal turbo seals, leading to oil blow-by and annoying exhaust smoke. This GryphonTek Signature Series Fitting is the professional solution to regulate pressure and protect your turbo’s longevity.

  • Precision 1.8mm Restrictor: Features an integrated 1.8mm orifice, specifically sized to provide optimal lubrication to the VJ35 bearings while protecting seals from high-pressure spikes.
  • Seamless 4AN Conversion: The essential bridge for upgrading your MSM. Replaces the restrictive factory banjo setup with a secure -4AN flare, allowing for a simple, leak-free connection to modern 4AN PTFE braided feed lines.
  • Dual-Style Compatibility: Designed to replace the factory-style banjo bolt (B660-14-615) with a high-performance 4AN adapter, ensuring a professional fit even in the MSM's cramped engine bay.
  • Rust-Resistant Finish: Machined from high-strength steel and electroplated for maximum corrosion resistance, ensuring long-term reliability in the intense heat of the MSM turbo "hot pocket."

Why Upgrade / Why Choose +

When replacing your aging or discontinued MSM oil lines, the connection to the turbo is the most critical point. The original factory banjo bolt setup is often difficult to reuse and prone to seepage. By converting to a 4AN oil feed adapter, you eliminate the headache of aligning rigid pipes. This fitting provides a clean, secure -4AN flare that makes installing a flexible 4AN PTFE braided line a "plug and play" experience.

The GryphonTek VJ35 Restrictor is a "must-have" for any MSM refresh. It solves the common "blue smoke" issue by managing the oil flow management at the source. Whether you are maintaining a stock collector-grade MSM or building a high-performance Miata, this fitting ensures your IHI VJ35 receives the perfect amount of oil without compromising the turbo's internal seals.
