How much psi can stock internals hold?

Boost is not relevant, it is your power output that you need to be concerned about. Regardless, you will be fine on the stock bottom end with a safe tune.

X2.
Pump gas doesn't usually equal very high boost on a dsm motor. I'd be more focused on what kind of power goals you have than how much boost you want to run.

Last summer on e85 I ran around 32-34psi daily through my stock 6 bolt and had boost spikes of 38 at the end of the year on the dyno. Also probably have around 30 pulls at 30ish psi plus a 75, but that was with an amazing tune from Shane @ DB.

Either way I would take it over to Shane @ DB so you can get the most out of it as safely as you can.

Stock cams and stock intake manifold?

Maybe 280-350whp FWD on a Dynojet. Just make sure they have all the hardware/software to properly datalog your car for knock.
