200 HP to the wheels

Hey everyone

I'm in the process of figuring out what kind of engine I want for my swap. I plan on performing the swap late this winter and early spring, so I want to get as much info as I can before I decide what motor to put in.
My goal for right now is to put down 200 Hp to the wheels. What would be the easiest/cheapest way to do this? Which engine setup would you recommend in order to reach this goal?

Thanks for your help, I look forward to your replies!
