Hey, I just notice that the 1989 944 had a Displacement of 2688 cc and the HP of 162 @ 5800 RPMs. But the 89 944S had a Disp of 2688 CC 188 @ 6000 RPMs. But a bigger engine was made, The 89 S2 Disp. of 3000 cc

HP is 208 @ 5800 RPMs. That's almost to a stock 86 944 Turbo with 217 HP.
The 90 & 91 S2 had Disp. of 3000 cc with 208 hp @ 5800 RPMs also.
If you don't have an 89 we all have a Disp of 2479 cc. I want 3000 cc!!
