Are you contemplating simply changing the spring for quick hp? I wouldn't unless you take precautions of an larger I/C , increase fuel enrichment for cooling and to deter detonation, exhaust upgrades, etc. I have a 930 motor that we checked c/r before even thinking of going to 1bar. I could go as high as 1.4bar, but that would make me nervous with stock internals so I am limiting myself to 1 bar with a full bay I/C on the 930 motor with a crossed drilled crank and balanced rotating assembly as well as efi for fuel control. There is some great experience on this forum that can help.
