How much RAM?

Hello list :)

I wonder if there is any possibility to calculate the estimated amount of RAM 
needed for an Oracle instance to run smoothly. To be explicit, I have a 2-node 
Oracle 10g RAC running on SuSE Linux, with 4 CPUs and 8 GB RAM each. There are 
already four instances installed each of which equally uses 2GB RAM. For the 
machines are avg. 80% idle (rather small databases, few users), we are thinking 
about adding another two instances to the RAC which have a total of about 200 
(~130 + ~70)users together. So, can I somehow figure out how much the basic 
usage for one instance is plus a variable amount depending on the number of 
users?

Any help appreciated - hints, infos, links etc.

Thanks in advance!

Cheers,
