Is there any companies that sell and make super chargers for that would work with the 4.0L OHV V6's. Basically I want to super charge my 1994 Ford Ranger 4.0L Ranger. I know that they make super chargers for the newer 4.0L engines. But I cant find any info on super chargers for the 4.0L OHV engines.

If they don't make a super charger for the 4.0L OHV engines, what turbo would be safe to use with a bone stock motor, and how much boost could I run in a stock 4.0L OHV engine?
