high compression question

I am planning on doing the PI swap on my 96. If I have a compression ratio of 10.3 to one on a N/A daily driver, is there any danger to my engine? I will be using 91 octane fuel, as there is not any higher octane fuel around here. So as long as I don't go with forced induction right now and use 91, will I be ok, or are there still any hazards. Thanks a lot for any advice.

You should be fine, but its all in the tune. If you run a tune with the timing advanced you will need to run 93, but I am sure you can have the tuner set the car up for 91 octane (or the stock tune, which will be fine)
