need more power

I have a 1982 regal limited 3.8 with 28k miles. This car is stock and i would like to pump some life in the motor, like turbo or some other means.

there is not really much you can do with that engine. I would not turbo it compression is too high right now. That and the turbo blocks where casted with a higher nickel content making it stronger. Sell it and get a 86 or 87 Turbo Buick. (more cars than the Grand National got that drivetrain. Regular Regal's,Limiteds,T-types,)
