I hope YOU are kidding. The guy says he wants to add a forced induc-
tion system, which a turbo is. Yes, you can get that kind of power out
of a 4 banger, especially a weak one. In rough terms, if he can 
achieve 0.5 atm of boost at 5000rpm, and assuming horrendous losses
costing him half of that, he will get nearly 25% more torque than he
is in N/A form. If the Chrysler makes 80hp @ 5000rpm in N/A form(and
we know it makes much more than that), he will have his additional
20hp. His goal is easily achievable.
