Yes you can put a turbo on it and yes it will last. If you don't intentionally brake it.
I believe others have said similar things before me somewhere here in the forum(?), but still here's a little lengthy answer:
Completely stock B6254/B6304 engine internals will take around 300hp with no problem. High compression does cause need for good ignition adjustment if not using E85(if available). Even a lower hp gives a nice feel and more driveability.
If you have to replace headgasket for any reason, I would fill the gaps between cylinders with 0.8mm shims in any case. Prevents the block cast from falling towards the gap and therefore cylinders from cracking. Have had and seen several stock 5- and 6-cyl engines with this failure due to overheating badly or other reasons. Those reasons on boosted engines being most likely overboost, fuel or spark problems, etc.
260-270hp is completely doable with stock 960/x90 Motronic, E85, 2.8l T6/2.5T(300cc) injectors and around 4bar base fuel pressure. No other mods needed than to add turbo and make a new exhaust. Or at least rear muffler because stock is restricting as hell.
Did a 245 few years ago with stock -95 2.5l, M90 and T6 turbos. According to 1/4 mile had ~260hp with 0,5bar boost or so. Great driveability and good mileage. And just did one 965 -95 with stock 2.5l, M90, HX40, built exhaust. Fuel pressure might be around 4.5bar? Dyno said 287hp on 0.5bar boost. On the sheet it looked like only thing restricting power was stock rev limiter
Dyno runs:

And might not apply OP:s car or question, but stock 2.5l block shoud take at least 600hp with gaps filled so there is no problem from that side. 550hp is completely on the safe side. Of course good blocks are getting harder to find and 2.8l T6 bottom end is a good replacement. Nonexistant wear on cylinders even on high mileage engines and needs just rods and cylinder gaps filled for 700hp...
