The 1600cc CVH engine and gearbox had the following
revisions over the Series I unit:
· The Garrett AirResearch TO3 turbo used a revised central
housing which allowed the engine coolant (water) to flow through
it. Thus improving turbo cooling and longevity.
· Revised engine management settings.
· Lower overall gearing (final drive ratio changed from
4.27:1 to 3.82:1).
· Improved and toughened gearset, featuring an additional
pair of bolts for the crownwheel.
· The Limited Slip Differential (LSD) was retained, with
an improved softer lock-up action.
· Clutch enlarged by 20mm to 220mm.
· New fuel injection system was provided by a Bosch KE
Jetronic unit.
Even
with these various engine improvements, the engine still produced
132 bhp at 5750 rpm (250 rpm lower than the Series I engine.)
Similarly the maximum torque of 133 lb/ft was produced at 2750
rpm, again 250 rpm lower.
Suspension changes included:
· Stiffer front and rear springs, increased to 135 lbs
at the front and 291 lbs at the rear.
· Uprating the anti-roll bars to: 24mm front and 16mm rear.
