SneedSpeed BMW B48 Engine Rebuild Kit
The BMW B48 is a strong modern turbo engine, but when it is worn out, damaged, or being pushed for more power, cheap rebuild parts are not the answer.
The SneedSpeed BMW B48 Engine Rebuild Kit gives you the parts needed to rebuild the engine the right way, with components tested and selected for fitment, sealing, durability, and real performance use.
Every kit includes the SneedSpeed Super Duty Head Gasket because cylinder head sealing is one of the first places cheap rebuilds fail.
All kit components are SneedSpeed parts unless otherwise stated. When a component is supplied by a partner manufacturer, it is selected to meet SneedSpeed build standards for fitment, durability, and performance.
Kit Options
Street Kit — Re-Ring Kit
For B48 engines being refreshed without replacing the pistons.
The Street Kit is for rebuilds where the engine is being re-ringed, resealed, and refreshed around the original piston setup. It includes the rings, bearings, gaskets, seals, SneedSpeed Cryo timing components, and SneedSpeed Super Duty Head Gasket needed for a proper engine refresh without stepping up to a piston replacement kit.
Includes:
- Piston ring set
- Main bearings
- Rod bearings
- Thrust washers, if applicable
- Complete gasket set
- SneedSpeed Super Duty Head Gasket
- Front and rear main seals
- Valve cover gasket

Sport Kit — OEM-Type Pistons
For B48 rebuilds that need new pistons while keeping the engine close to the original factory design.
The Sport Kit is the right choice for a stock-style rebuild, daily driver repair, or mild performance street build where forged pistons are not required. It gives you new OEM-type pistons, matched rings, bearings, gaskets, seals, SneedSpeed cryo timing components, and the SneedSpeed Super Duty Head Gasket — without stepping into a full race-level piston package.
Includes everything in the Street Kit, plus:
Super Sport / Race Kit — Forged Pistons, Head Studs & Coated Bearings
For B48 builds where stock-level parts are no longer enough.
This kit is built for higher horsepower, upgraded turbos, racing, and hard street use. It upgrades the core failure points with forged pistons, coated performance bearings, and head studs for stronger cylinder sealing under boost.
Use this kit when the goal is not just to rebuild the engine — it is to build a stronger foundation for power.
Includes everything in the Sport Kit, upgraded with:
- Forged pistons with matched ring set
- Coated performance main bearings
- Coated performance rod bearings
- Head studs
- Main studs, where applicable
Professional installation is recommended. Engine rebuilding requires proper measuring, machining, clearances, torque procedures, and assembly practices.
