Based on a guess of the limited info available, the chainline would probably be aprox. 5mm further out. So, if the Suntour info is correct giving a 48mm chainline with a 113 BB then you'll be at aprox. 53mm with the long side of your current spindle on the DS.
This is based on common 113 BB that has symmetrical or nearly symmetrical sides (don't know what BB Suntour is basing their measurements on), and an 120mm older spindle which is 4-5mm longer on the DS (info pulled from Sheldon Brown's BB data). The link is in the 'sticky' to Sheldon's site and go to BB length article.
The longer chainline by 5mm wouldn't be much of an issue if your riding style/terrain would keep you on the smaller cogs end of the cassette. A 5mm longer chainline would be about 1.5 cogs to the outside.
Don't know the specifics of the Suntour, so can't guess of the effect on the Q distance (thread distance between the pedals).
