1.4L 8v - 840 726
The 840 726 is the turbocharged 1.4 8v of the R5 Alpine Turbo, also carried as C6J 750, and its compression ratios say so: the WÖSSNER forged piston kit runs 7.5:1 at 76mm, 7.6:1 at 76.6mm, 7.7:1 at 77mm and 7.9:1 at 78mm and 80mm, figures that belong to a blown engine. This is also the only 840 page that carries valve timing. CATCAMS supply a sport camshaft and an adjustable cam gear, so the timing can be dialled in on the bench rather than left where the factory put it. Bottom end and valve timing are therefore prepared together here.
