Design, development and variant notes
Most M52 engines used an aluminium block; many early US and Canadian installations used iron blocks, with exceptions. Original M52 engines have inlet VANOS, while M52TU added exhaust-cam timing adjustment.
Wikipedia describes bore wear associated with high-sulphur petrol in some Nikasil-lined engines and later iron-sleeved designs. The North American S52 is an M52-related performance engine and uses an iron block.
Variant dimensions and compression
These values are associated with the named variant and source qualifier; equipment and market specifications can differ. A dash means the value is not listed here.
