Engine Overhaul / Replacement Engine 1.8 TSI / TFSI BZB (EA888 Gen2) Reconditioning

Engine overhaul / replacement engine 1.8 TSI / TFSI BZB (EA888 Gen2) rebuild — better than factory standard

The BZB is a 1.8-liter TSI/TFSI four-cylinder (EA888 Gen2) from the Volkswagen Group with 120–160 hp, widely used in Audi, VW, Seat, and Škoda models. MIK Motoren rebuilds this engine to a level that significantly surpasses the original production standard — known weak points such as oil consumption and timing chain wear are permanently eliminated.

MIK Upgrades — why this engine lasts longer

The work carried out includes not only the replacement of all wear parts, screws, and gaskets, as well as the machining of the mating and running surfaces, but also the replacement of components that, at the factory, are marked with weak points and the Limit the engine's lifetime.

• upgrade oil pump — The biggest weak point of this engine is its oil pump, which does not deliver enough oil pressure from the factory and keeps causing failures. Without sufficient oil pressure, warning messages, rattling noises, and a loss of power quickly become noticeable and almost always lead to engine damage. For this reason, we rely on a specially developed oil pump that increases oil pressure across the entire rev range and protects the engine from wear.
• reinforced pistons — When tuned for more power or driven in a sporty manner, this engine is increasingly prone to piston damage in the ring zone. It is not uncommon for oil consumption of 0.5L/1000km or more to occur, and compression, as well as power, decrease significantly. The higher temperature in the combustion chamber then puts particular stress on the pistons and valves. Modified pistons, improved piston rings, and a specially honed cylinder surface provide the remedy.
• high-quality bearing shells — During the overhaul, all components are precisely measured and machined. The bearing clearance between the individual components is set for lifetime and performance, ensuring especially smooth engine operation. Combined with high-quality bearing shells, this engine is also ideally suited for sporty drivers.
• reinforced timing chain kit — The increased wear of the timing chain is largely related to the chain's design and the freedom of movement of the chain links on the guide rails. A modified chain design, along with a special guide rail geometry, ensures maximum lifetime of the timing chains in this engine.
