Just like most things, it all depends on your budget and which engine you're swapping, if it's the 2AR or K swap, you can get there easily. But those require lots of modifications and rewiring.

The 2ZR like mentioned before is straightforward, my guesstimate for NA application is around 150-165HP at the wheels with I/H/E upgrade and still be streetable, and that's plenty, that's almost doubles the stock WHP. I've seen a 2ZR outfitted with the 2ZZ intake runner! I'm giving out my secrets.
Turbo is another option, but the hard part about it is tuning the stock PCM/ECU. Those who have cracked the stock Toyota's PCM/ECU seems to be keeping the information to themselves for profit. Unlike Honda, with the HONDATA, once you have the added circuit board installed, you can mess with the settings all you want. You could piggy back or get a standalone, but again lots of money and that's a lot of setting that you'd have to mess with to get all the amenities functions to work like the stock.

I'm not sure what the xB's final drive is, is it's the same as the xD's? The xD's manual transmission has the same 1st to 5th gear ratio as the Yaris, except the final gear ratio, which higher. I'd go with higher final drive, and just swap out the 5th gear with the C6X 6th gear for highway crusing. Giving out my secrets again.
