For CVH Rs Turbos up to 300bhp we offer uprated IB5 gearboxes with the option of shot peened and polished gear sets, and either an uprated viscous LSD or a quaife ATB. All uprated gearboxes are used with uprated cerametalic clutches.
Above 300bhp we offer a 6 speed conversion using the mk2 focus RS gearbox. This conversion also requires the use of a zetec bottom end. (Not compatible with CVH block due to starter location). The vehicle chassis has to be modified with new engine mount locations, and the conversion includes new flywheel and clutch along with new driveshafts with intermediate shaft to give equal length outer shafts. It also requires a cable conversion to the gear shift and adapter plate to fit gearbox to zetec block.
