Generally speaking, because of the turbo boost the effects of pinging are
far more dramatic. You'll hole a piston far quicker in a turbo engine than
a non-turbo engine.
That said, most have a knock sensor that knocks back the ignition timing, or
kills turbo boost. Which makes the car as fun to drive as watching mold
grow on a shower wall. Defeats the turbo. Some are soft, some are very
abrupt. It depends entirely on the car.
Current turbo beast drives quite well and docilely on 89 octane gas.
Previous one was hyper demanding of high octane fuel, and would fall flat on
its face when romped and ping was detected with 89 octane.
