sr20det compression test results. Seeking advice

I have a 91 redtop sr20det with a little under 81k miles and decided to compression test it last night before getting ready to install a new turbo (gt2871r) and supporting mods. Motor is bone stock (as far as I know) aside from basic bolt ons...exhaust, fmic, intake.

I did this on a warm motor, with the throttle wide open, and all the plugs out. This was done at 5600' elevation so I believe these numbers are about 15% lower than if I were to do it at sea level. Here are the results:

Dry: 110 105 113 115
Wet: 130 127 135 144

Are my rings toast? Do I need a bottom end rebuild?

If so, what are your suggestions? My plans are just for a gt2871r .64ar, ewg, s3 cams to get around 375-400hp. I have no plans to go any further than this in terms of power. I don't drift or daily drive the car.

Thanks
