ABOUT REMAN ENGINE
5.5-Liter engines: Mercedes-Benz manufactured their 5.5-liter V8 and V12 engines as a replacement for the older 5.4-liter V8 M113 class motor which stopped being put into all production vehicles except for the SLK in 2003. In the 5.5-liter V8 engine configuration, Mercedes produced 3 engines that are all similar but slightly different and labeled them in different classes: M273, M157, and M152. Inevitably, each one of these Mercedes V8 engines was given different cylinder heads but they all share the same aluminum block beside the M152 engine which was given an aluminum alloy alternative. It’s important to note that there is also a 5.5-liter V12 engine that Mercedes used for over a decade in the M275 class that also has an aluminum block and cylinder head.
