Usually on a turbo NA engine (lol) the rods are the first to go.
So torque would be the biggest limiting factor there.

Usually people who boost end up replacing rods/pistons eventually though, if not as they were having the snail put on.

if i'm not mistaken, often times rally cars don't run wastegates, they just let the boost spike as high as it will go, and it trails off at higher rpms due to the restricter.
as far as turbo'd n/a engines, it's alllll in the tuning (well, mostly). you could run 5psi and blow your ring lands to pieces, or you could 10psi and have a safe, reliable engine. tuning, fuel, and maintenance. -Mike

i'd think any extra weight on the front of this car will diminish other performance characteristics; if engine swap is really something of interest, I could possibly see the 2.5L h4 turbo getting stuck in there as a first choice
