I'm planning on doing a complete engine rebuild at some point when i have the money, and I'd like to build it with as much power as I can within the next couple of years. For starters, what's a good engine swap that will hold up to high horsepower and torque? And from there, what's the best way to put a couple hundred horsepower into it?

Are you planning a turbo or n/a build?

All of the Subaru engies are pretty tough when maintained. The RS engine is the 2.5 N/A version...The WRX engine is a happy medium where as...The STI engines are race ready
