Protect your new turbo with a complete install kit matched to your vehicle. Turbo install kits include the gaskets, studs, nuts, crush washers, and O-rings needed for a clean, leak-free installation, and many also include new oil feed and drain lines. Our Turbo Install Kits cover: Cummins, Duramax, Power Stroke, EcoBoost, EA888, Subaru, OE replacement, remanufactured turbos, and performance turbos. Gaskets and seals are one-time-use parts, and old oil lines can hide debris or coked oil that starves a new turbo on first start. Installing fresh hardware is one of the simplest ways to prevent early turbo failure and leaks. Shop by year, make, model, and engine to find the right kit for your turbo replacement or upgrade.

Install kit questions usually come from a problem after a turbo replacement: an oil leak, a ticking exhaust leak, a coolant drip, or a new turbo that failed early. The answers below cover the most common installation problems, which parts should always be replaced, why new oil lines matter, and how install kits affect warranty coverage. Because install kits are matched to specific vehicles and turbos, confirm fitment for your exact year, make, model, and engine on each product page before you buy. For help choosing the right kit for your turbo install, talk with your tuner or contact our team.
It's strongly recommended. Gaskets, crush washers, and O-rings are one-time-use parts, and reused parts are a common cause of leaks after a turbo replacement.
Common causes include a reused or wrong drain gasket or O-ring, a kinked or restricted drain line, or high crankcase pressure. Check the drain path before blaming the turbo.
A ticking sound under load commonly points to an exhaust leak at the manifold, up-pipe, or turbine inlet gasket. Recheck gaskets and torque.
It's commonly recommended, especially if the old turbo failed. Old lines can hold debris or coked oil, and clogged filter screens can starve a new turbo.
It's not recommended. Exhaust studs and nuts commonly corrode, stretch, or lose locking ability after heat cycles.
Early failures are commonly caused by oil starvation from a blocked or old feed line, sealant in oil passages, debris left in the intake, or skipping pre-lube.
