Yea, the 2ZZ has a pretty high compression; not that you couldn't go FI, but the boost can't be that high, and you really need to watch your A/F ratio when running boost; It was designed as a NA motor though. I think the 2ZZ could hold up if the boost was around 5-6 PSI or so, but more boost requires a lowering of the compression ratio, not to mention beefier internals.
The short, boxy stroke of the 2ZZ would be nice either FI or NA, but the factory designed it to be a high-revving, NA motor; Similar to the VTEC motors. Yes, you can boost those too, but not without either keeping the boost low, or by building up the engine first.
Cars like the SRT-4, Evo Lancer, WRX and all the other factory turbos is simply that they were designed to run boost from the factory. Fuel Systems, compression ratio, gearing, valvetrain; Everything is ready to run FI from the factory.
Serious boost will require some engine work, but even modest boost on a 2ZZ will show good gains, especially low in the revs, where power is needed most.
So if you're looking for improved performance and daily drivability, a basic, low boost turbo or SC would probably be a good investment. That's just my opinion, though.
