The 1995-1999 uses the 606 engine. Only the 1998 and 1999 were turbocharged. I know that the turbo version can be 'chipped', but I do not know about the non-turbo. I do not think that I would discount a non-turbo 606 engine. True there is less power, but I would think that the power would be much smoother and make for a very nice ride. My 1999 will jerk you around if you put the pedal down hard when the transmission is in the 'S' setting. I usually like to drive it in the 'W' setting except for when I fell like humiliating showing some teenager in his testosterone buggy.
