PEI posted a dyno graph a couple years back (no idea where it came from or where it is now) but it was from someone's b30 build that made about 300whp NA revving to around 8k rpm and if i remember correctly, it also had the ITBs from a s54 attached to the head. aside from an ATI harmonic balancer and the vaio (spelling?) re-engineered oil pump at a minimum, there are other things you'll need. PEI would be the best to answer your question so hopefully he'll pop in here and share his knowledge.
