smileracing Turbo Oil Drain Line Kit for T3/T4/T04E/T60/T61/T70 — 40.5" feed, 21.5" drain, stainless braided, 7075 adapter

smileracing's Turbo Oil Drain Line Kit provides a complete stainless-steel braided feed and return solution specifically built for T3/T4/T04E/T60/T61/T70 turbochargers.

If you're assembling, upgrading, or repairing a turbo system, reliable oil routing is essential to protect bearings and maintain performance. This kit combines a long, stainless-steel braided drain line, an extra-long feed line, an aluminum adapter and the necessary fasteners and gaskets so you can install a tidy, leak-resistant oil setup without sourcing multiple parts. Components are sized and finished for durability under elevated temperatures and pressures typical of boosted applications.

Will this fit my turbocharger model?

The smileracing kit is engineered to be compatible with a range of common turbo housings: T3, T4, T04E, T60, T61 and T70. Fitment relies on typical industry port sizes and includes adapters to bridge common thread and AN fittings. Always verify your turbo’s oil port thread and flange type before installation to ensure alignment.

• Designed for T3/T4/T04E/T60/T61/T70 turbo families
• Includes 1/8" NPT to -4AN adapter for common conversions
• Multiple fittings and gaskets for straightforward matching to turbo ports

How does the kit manage oil flow and prevent seal issues?

The included inlet adapter features an internal flow-limiting design to reduce excessive oil pressure at the turbo, which helps lower the risk of blown seals. The braided lines offer structural resistance to expansion under pressure, keeping delivery consistent and preventing drips. Proper routing and secure fittings further reduce the chance of leaks at high engine temperatures.

• Special inlet adapter limits oil volume into the turbo
• Stainless braid minimizes line expansion and preserves pressure stability
• Complete gasket and screw set ensures dependable sealing

What are the material and length specifications?

All flexible lines are stainless-steel braided over a core for abrasion resistance and heat tolerance. The drain line measures 21.5 inches and uses -10AN return fittings, while the feed line is 40.5 inches end-to-end with a 3/8" internal diameter for robust capacity. The adapter is machined from grade 7075 aluminum for strength and light weight.

• 21.5" stainless steel nylon-braided oil drain line (return fittings -10AN)
• 40.5" stainless steel oil feed line, 3/8" diameter (extra long)
• Grade 7075 aluminum 1/8" NPT male adapter and -4AN male flange fitting

What comes in the box and how straightforward is installation?

The kit arrives with everything needed to fit the turbo and complete a sealed oil circuit: feed and return lines, the adapter fittings, and the necessary screws and gaskets. Install is simplified by pre-chosen lengths that suit most engine bays, but trimming or re-routing may be needed for custom layouts. Use recommended torque values and fresh thread sealant on NPT joints for the best leak-proof result.

• Complete set: feed line, return line, adapter fittings, screws, and gaskets
• Pre-measured extra-long lines reduce the need to join sections
• Installation requires basic hand tools and proper sealing compounds for NPT threads

Who is this for: The smileracing Turbo Oil Drain Line Kit is aimed at enthusiasts, tuners, and professional mechanics building or servicing turbocharged engines that use T3/T4/T04E/T60/T61/T70 family turbos. It's a practical choice if you want durable, long-length stainless-braided oil plumbing with included adapters and hardware for a clean, reliable installation without sourcing multiple separate parts.
