i was actually thinking about this kind of thing today. i have a d16z6, but i suupose some of the same principles could be applied. without boost, i think you would have to go with N2O. but like Never said, they didn't say stock internals. that would probably be impossible. but i'm sure if you really built the motor the right way, 200hp isn't impossible. i was thinking this because i want to build by sohc vtec motor up instead of swapping, atleast for now. a d16 pushing 200hp would be awesome.
