The S2 was something else. It, too, had the new standard goodies of the base and Turbo models, but it looked like a Turbo and was almost as strong, thanks to a 16-valve engine stroked to 88 mm (on the 2.7’s 104-mm bore) for no less than 3.0 liters, making it the world’s largest four-cylinder in regular production.
Despite mounting corporate troubles, the S2 showed no less engineering care than any other Porsche. For example, the new 3.0-liter actually weighed 15 percent less than the old 2.5, thanks to joined cylinder sleeves without water jacketing, shallower jackets elsewhere, and thinner block walls. Switching from cast to forged aluminum pistons didn’t save weight but did wonders for high-speed durability.
A revised intake system gave a “pulse charge” effect for more high-end power (it was noticed above 4,000 rpm) and a catalytic converter moved closer to the engine to shorten warm-up time for reduced emissions. An adaptive knock sensor and the addition of an on-board diagnostic system to allow tracing any intermittent faults in the Bosch Motronic engine computer rounded out the improvements. With all this, the big four now delivered 208 horsepower at 5,800 rpm in U.S. tune and 207 pounds/feet of torque peaking at a usefully low 4,100. And that was on regular gas, despite tight 10.9:1 compression.
