So whats the deal with boosting a b16?

I was gunna go all motor type R in my rex which would be very kool, or a boosted b16. how easy is it to get this set up into the 11's? ...the only reason i say 11's is cause it seems very possible with a CRX and a b16, and a greddy turbo kit.

what do Si's run with a greddy turo kit? i guess you can jsut take that number and knock off, what? like a second or two? haha.

thanks for your time.
