Every Boost Lab turbocharger is assembled by the same technician, to the same standard, every time. BL turbos are built on quality Garrett and MHI-based internals -- the same components we use to build them are the same components we use to rebuild them. The difference is that we know exactly what spec your turbo was built to.
A BL turbocharger is not a stock unit. Every one is a modified build assembled in-house with components and specifications that are proprietary to Boost Lab. Sending it anywhere else means sending it somewhere that does not know what is inside it.
Every BL turbo is assembled to a known specification. The compressor wheel trim, turbine wheel design, bearing selection, and balance target are all documented. We rebuild to that exact spec -- the same Garrett and MHI-based internals used to build your turbo originally go back into it on the rebuild.
Every BL turbocharger is built by the same technician for quality assurance. That same standard applies to every rebuild. Your turbo is not a production line unit and the rebuild does not treat it like one.
The BL Carbon Seal turbos use a Garrett-style carbon seal architecture with a Boost Lab proprietary seal plate. The seal plate is a BL-specific component. When a carbon seal unit comes in for rebuild, we restore it to the original BL build spec -- the same assembly standard as when it left our shop.
Every BL turbo leaves the shop VSR balanced. Every rebuild returns VSR balanced to the same target. A turbo rebuilt without VSR is not a turbo rebuilt to BL standard.

The BL Carbon Seal turbocharger line uses a Garrett-style carbon seal architecture paired with Boost Lab proprietary seal plates manufactured to our own specifications. Carbon seals offer superior sealing performance compared to standard piston ring seals under high-boost, high-temperature conditions -- reducing oil consumption past the seals and improving long-term reliability under sustained performance use.
The seal plate is a BL-specific component. The rebuild restores the turbo to the original BL assembly standard with the correct seal plate and new internal components as required.
When a Carbon Seal unit comes in for rebuild we assess the seal condition, compressor and turbine wheel condition, and bearing housing. The rebuild restores everything to the original BL build spec with new internals and seal components as required.
The BL turbocharger lineup extends beyond Subaru. All BL turbos across every platform are built to the same standard and fully supported for rebuild service.
Direct bolt-on for Evo 8 and Evo 9. MHI TD06SL2R-based modified build. Full rebuild support.
View Mitsubishi lineup →500HP to 1,600HP. Street builds, custom setups, and high-horsepower race applications. Every unit built in-house and VSR balanced. XR series adds dual ball bearing construction. Carbon Seal variants available.
Ford PowerStroke GTP38 OE-replacement and expanding diesel/truck platform coverage. Full rebuild support.
View Diesel lineup →BL vehicle-specific builds for Nissan, BMW, Hyundai, and Honda. Contact us with your model to confirm rebuild support.
View all platforms →A properly installed BL turbocharger running clean oil in a healthy engine does not wear out on a predictable schedule. Rebuild need is condition-based. These are the primary causes we see.
Start a rebuild request and ship your BL turbocharger to us. We will assess, document, and rebuild it to the original BL specification.
