The sad fact is that our 924S and 944 cars are NOT Tri-Five Chevys or fifties Morgans. They will never attain “classic” levels, and we won’t see an ’84 944 with 320K on the odometer bring 2.1 Million at Barrett-Jackson. But these cars were made to be loved and driven, driven hard, driven at autocrosses and track days, and even in club racing. So make a list, prepare a budget and get to work.
It seems that when Audi designed the 2.0L engine for the 924 and other cars of the early and mid seventies, they decided that strength was important. So, the crankshaft and connecting rods are all forged, not cast. That instills a lot of confidence in this little engine as far as longevity.
