BorgWarner 3LM-26 Core Assembly

This is the BorgWarner 3LM-26 core assembly, part number 198290. It's a critical component for rebuilding or upgrading your vehicle's turbocharger system. The core assembly, often called the CHRA (Center Housing Rotating Assembly), contains the turbine and compressor wheels along with their shafts, housed within the center bearing housing. This is the heart of the turbocharger, responsible for spinning up to high RPMs to force more air into your engine, increasing power and torque.

BorgWarner is a well-known name in forced induction, and this 3LM-26 core assembly is built to their standards. It's designed as a direct replacement for specific applications, meaning it should fit right into the existing turbocharger housing. When you're rebuilding a turbo, replacing the core assembly is often the most practical approach, as it addresses the most common wear points like the bearings and seals. This ensures that your rebuilt turbo will perform reliably. The assembly includes the turbine wheel, compressor wheel, shaft, and the center housing with its internal oil and water passages for cooling and lubrication.

Because this is a core assembly, it's intended to be installed into the existing compressor and turbine housings of your turbocharger. This is a job that requires careful attention to detail and proper sealing to prevent oil leaks or boost leaks. If you're undertaking a turbo rebuild, having a fresh core assembly like this BorgWarner unit is essential for restoring performance and ensuring longevity. It's important to note that this part is not CARB approved and cannot be shipped to California.
