V8 M113 (V8 M113) — better than factory
Engine overhaul and replacement engine V8 M113 — professional reconditioning for Mercedes: CL 55 AMG, S 55 AMG. Depending on the variant, this gasoline engine delivers 354 to 500 hp (AMG). In AMG specification, the V8 M113 is a classic among high-revving naturally aspirated eight-cylinder engines — built for vehicles that demand far more than standard operation. Timing chain wear, bearing wear at high mileage, and piston damage under high load are known weak points. MIK rebuilds this engine to a level that Mercedes did not achieve at the factory — with targeted upgrades that significantly extend lifetime under typical AMG loads.
MIK upgrades — why this engine lasts longer
The overhaul at MIK Motoren includes not only the replacement of all wear parts, bolts, and seals, as well as the machining of all mating and running surfaces. Components that are known to have factory weak points and limit the engine's lifetime are also specifically replaced. The following MIK upgrades extend lifetime drastically:
- Timing chain (reinforced) — Increased timing chain wear is a classic ramp-up problem on the M113: in the original version, the chain design and guide rail geometry limit lifetime. MIK uses a modified chain design with revised guide rail geometry — maximum lifetime, even under full load.
- Reinforced pistons — With sporty or performance-enhanced driving, the M113 shows piston damage in the ring zone. The consequences are oil consumption, loss of compression, and reduced performance. MIK uses modified pistons with reinforced rings and a specially honed cylinder surface.
- High-quality bearing shells — All components are measured precisely and set up for lifetime and performance. The precisely adjusted bearing clearance ensures exceptionally smooth engine running — including for the sporty driver.
