can I put a 140mph speedometer in a 4cyl? I cant stand the 85 mph one. What is needed if anything to do so?

No one has given me a straight answer.... will it bolt right in and work ?
car is a turbo car and 85 mph is too slow, I want a 140mph speedo.
Someone please help.........
Besides, a 2.3 n/a has a hard enough time pegging the stock speedo...
