Installation & Compatibility Guide

Correct plumbing is the most overlooked part of turbo performance. To ensure a reliable setup, keep these technical requirements in mind:

  • Oil Control: Ball bearing turbos typically require specific oil restrictors to prevent seal damage, while journal bearing units often require full flow.
  • Drainage: Ensure your oil drain flange and return lines are sized correctly—at least -10AN or equivalent—to allow oil to return to the sump freely.
  • Sealing: Use high-quality adapters and AN fittings to prevent high-pressure oil leaks and ensure a service-free installation.

Fittings FAQ

  • What size feed line do I need? Most setups use a -4AN feed line, but always check your specific turbo model's requirements.
  • Can I reuse gaskets? It is highly recommended to use new gaskets with every oil drain flange or feed adapter install to ensure a perfect seal.
  • Are these fittings universal? While many utilize standard AN sizes, the flange patterns vary, check your order carefully.
