My standard series 3 with a landie petrol engine would cruise at 110kph on the highway with a top speed of about 120. Even my old series 1 with a holden 161 would do the same so if you are only getting 80 -90 there is something wrong. Even with the original 2 litre engine, the series 1 still did 55-60mph with a long, long, long, long, long runup.
Both were my everyday cars that were used to travel from Newcastle to Canberra or Nowra each weekend - so "high speed" driving on expressways was the norm for both of these. The series 1 with the 161 fitted and the the windscreen down was limited to about 75mph indicated on the speedo by the wheel wobble from the slack front end.
Oh - speeds were not based on the speedo - based on passing other cars on the freeway with large LCD speedos that I could see as I zoomed (well crawled) past them.
