I think you'd be safe on more like a 100, better to keep it at a 100 and be conservative... I know the NBS (99-06) and NNBSs (07-Current) can spray usually up to around a 150 on a stock motor... I'd say spray the crap out of it until it blows, then start on the swap... I definitely don't have any experience with nitrous though, so maybe one of the smarter guys will chime in for you.
