How much HP can a stock system handle?

Been toying with the idea of putting twin turbo's on my 2012 G-37 Coupe.
I really bought it for my winter driver cause it's a 4 wheel drive but it gets around OK in traffic and it's already had a few performance things done to it so I'm just wondering if the engine and power train can handle the extra horsepower. I don't want to be tearing something up every time I get a little hard on that right most pedal.
I do tend to use the horsepower I have available sometimes, and if I make this car fast, which it certainly would be if I added a supercharger or turbocharger my 71 year old *** might be getting tickets again too...
Do you think the stock drive train would handle turbocharging?

its not really the HP that leads to failure with these cars its the Torque.. From what Ive heard you start to see failures around 550+tq so... good to stay under those numbers. By the way if you're deciding to go twin turbo I'd love to know your budget ....

Being an old fart of 71 years and liking fast cars, and now having my first Japanese Tech, if I dig around in the mattress a bit, I can probably come up with the 13+ grand I been quoted. I'd rather have a car like my G 37 beefed up a bit with about 35 G invested than a brand spanking new Escalade (barf barf) that would probably cost twice as much and still be just traffic
