Whats wrong with the 83? lighter to start with and has manual steering. Cheaper A arms of steel too. I dont think you could but the 944S(87) into the 83 because they came from the factory with the Steel A arms and steering.

It's been a few years, but if I remember, the 83 was only 143 hp............ not exactly ITS numbers.......at any weight.........and no removable chip.
