1.2L 8v - XZ7R This page covers the engine build parts listed for the XZ7R 1.2 8v, fitted to the small Peugeot, Citroën, Simca and Talbot models of the 1980s. The range is deliberately narrow: one selected reference, a WOSSNER forged piston set, intended for a full rebuild of an ageing block. Forged pistons give far better mechanical strength than the original cast parts, which makes them the sensible choice for a rebuild or a fast road build. No other part family is currently listed for this engine.
