Buying Guide: How to Choose the Best Drop-In Turbo for Your 5.9 Cummins
Choosing the right drop-in turbocharger and related components such as oil return lines and intake elbows requires understanding a few key factors:

- Materials and Build Quality: Look for high-quality construction like TIG-welded aluminum or precision-machined components that withstand higher boost levels and heat.
- Complete Kits vs. Individual Parts: Oil return lines and intake elbows are often overlooked but vital to turbocharger longevity. Choosing complete kits with necessary gaskets and hardware simplifies installation.
- Warranty and Support: A robust warranty and clear installation support (tutorial videos, customer service) can ease the upgrade and repair process.
