Machine Work Required for Forced Induction

Honestly, I'm not sure what horsepower to expect. This is my first small block, and my first experience with EFI and a turbo. I would hope that with forced induction, 400 "drivable" hp would be possible. Remember, this will be my daily driver. I'm looking for reliability, 15-20 mpg, and the turbo is just for my ego and to slap the ricers.

My engine budget is flexible, as the car only cost me $200. So far, I've got $3,000 into it in paint. I'm hoping to do brakes, suspension, rearend, etc. for another $3,000. If I can do the engine for under $5,000, I'll have a kick-***, fun daily driver--and a lot cheaper than any new car.

As for internals, forged dish-top pistons, forged rods and crank are all part of the plan. As I said, I'm looking for reliability, so I won't skimp on the engine.
