You could run up to around a 50 dry shot shot of "nitrous." Don't say NOS, it makes you sound like you live a quarter mile at a time. You would want to pick up some colder spark plugs, NGK has some good copper plugs for nitrous. Your also gonna want to retard your timing. About two degrees every 50 shot you run. There are other things you could do if you were to run a little bigger shot, but if your only looking at a 50 shot, you should be fine with those simple upgrades.
