Depends, but in my opinion 320/340 crank HP is running it close to the edge, on stock internals.If you just crank up the boost with a boost controller you can not go as high as with a full remap.
Also the stock injectors and pump will be the limiting factor before the engine internals, as the stock 380cc injectors (is it a WRX wagon, not an STI)will run @ 100 duty cycle at 310-320 crank HP assuming the stock pump still works like a new one (and it's safe to say it won't work like a new pump after 17 years)

It depends on the tune to be honest.
I've seen tunes that used a lot of boost for a certain HP number, and have seen tunes with the same power, but much less boost.
But I would err on the side of caution, and not go much above 1.3 bar (with a good tune, DO not use a boost controller and just crank up the boost) on a stock EJ20 with a 16G.
Especially with the small slant mount IC, as higher pressures cause a rapid rise in charge temperatures.
I ran my car on 1.5 bar with a Super16G, but the fueling and ignition were mapped to suit,also I had a FMIC.

When I got my Scooby, the guy had set it up in a stupid way. It was boosting to 24 psi. I took it back to standard but it had messed up the engine. Yet to find out what the damage is. Haven't got round to rebuilding it yet. Bought a spare Scooby for parts and rebuilt the engine in that and did a swap
