Used to own a S2 190sport. The engine was better developed than the S1 the engine map made it better at all revs. Mine was dyno’d by scholar at 195bhp without any mods. It still suffered HGF so its not immune from the usual issues.
As mentioned above, the options list was huge, mine had dynamic shocks, LSD etc which were all extras.
Great car and a good one is a keeper.
