Not 60whp, but 72whp. I agree you'd be in the 290's, possibly 300whp with E85 on your BNR16G. So the move to the BNR68 would get you right around 40whp. Still, probably not enough of a jump to warrant all the trouble.

Look up tommypenguin's old thread... He had an FP Green, at altitude, and never loved it. He ended up downsizing turbos, I believe. I'd be cautious of going that route.

I posted my new #1 favorite dyno sheet ever from that '07 WRX dyno'd last month. Over 3100rpms of continuous tq/whp > 360... That guy's damn turbo spools a lot faster than my BNR68 and makes >40whp more peak. Makes me look really bad. Simple out-of-the-box FPHTA68 with 2.4" inlet. Possibly capable of 11's at Bandimere (mid 11's at sea level). Personally I would try to replicate his setup. You'd gain over 100whp up top and at no point in the powerband make less than what you are making now.
