The M5M, also known by its Nissan code MR16DDT, is the only modern direct-injection turbo engine in this run of pages: it powers the Renault Clio 4 RS and the Megane 4 TCe. Two references serve it here, and they belong together. WISECO forged pistons, 79.7 to 80mm bore depending on the option, keep compression at the 9.5:1 that boost demands. The COMETIC multi-layer steel head gasket, 81.0mm bore and just 0.71mm thick, holds boost pressure without adding chamber volume. This is the only page in the run where WISECO and COMETIC appear.
