So, my experience is, you can reach 997 GT3 performance with reasonable ride in street.

I am currently there, my car best time 2:20 in the track I participate, this is where most Caymans GT4 and 997 GT3 times.

A stock 991 GT3 should do 2:18-2:17 and 991.2 do 2:15 or less.

So, for myself to get there, I needed to invest in suspension (custom coilovers and full spl arms), OS LSD, OS clutch and flywheel, simple boltons and tune, brake upgrades (pads - rotors), and some other small details like bushing - mounts - cooling. Also, I drive on 200tw tires (Nexen sur4g). I don't know if I am forgotten something, but I have my build with all details.

Everything depends on the track itself, I gain time over other cars in braking and acceleration out of corners. Not a lot to expect in straights.

If I want to enter the territory of 991.1 or 991.2 GT3, I think I will need S2 Cams for better acceleration, full aero (splitter, wing mainly), weight reduction, full slicks. Aero good for 2-3 seconds, and slicks are good for another 2-3 seconds. So, it would be a 2:15 car.

Disclaimer, all estimations without cost, and all depends on the track I attend (Losail International Circuit).
