You'll find that this is the predominant small-chassis swap on Motorgeek, although lately it seems the 4.2 V8 is becoming wildly popular.
There are a lot of good build threads, such as:
Just to take a couple from the first page of search results.
In short, yes it will bolt up to the transmission just fine. I don't know about horsepower/torque numbers, but I have yet to hear of a major catastrophe with putting big power through the 4kq drivetrain. If you browse enough threads on Motorgeek you'll probably learn all you need to know as far as swapping. A good site to keep handy for technical stuff is this:

I've seen a lot of cool 20vt setups build from 034 Motorsport parts. I'm sure there are others out there, but that seems to be the most popular.
Since you're swapping into a car that already has a turbo setup, it might be easier than if you were starting with a stock car. The 20vt is a little different than the 10vt, but I can't think of anything that would be a deal breaker for someone doing their first swap if you have any kind of mechanical ability. If you look at the first link I posted there's a lot of detail shots to compare to.
I admit I've never messed around with the 20vt, so hopefully someone who has will chime in to fill in the blanks, but that should get you started.
