1998
In 1998, the engine supplier changed to Vauxhall, with 1600 single overhead cam engines being used. They featured a ported & skimmed cylinder head, standard Vauxhall camshaft, flywheel and clutch cover plate, two Weber twin choke 40 DCOE 151 (sidedraft) carburettors, main jets size 115, with K&N performance filters. The maximum power was 101 ps at 5,500 rpm and a max torque of 107 lb ft at 3,600 rpm. The main visual difference between the Fords and the Vauxhalls was that the Vauxhalls had a side-exit exhaust, as opposed to the rear exit of the Fords.
The early Vauxhall cars used the same Spax dampers with manual adjusters as the Fords, with an option to adjustable spring platforms.
