i have a 3071R turbo and boosts up about 4k on an SR20 so similar time on a B18 seeing that the capasicity is smaller same or longer time and that is with a .63 housing and larger trim.

i would stay the smaller housing but with that front you wont run out of puff on that boost level and also consider the turbos effecincy range and 8-10psi on a 30 with .86 isnt in it.
dont take this the wrong way..................but u can not compare an sr20 with 8.5 comp compared to a b18c with 11.1 comp..........

the difference in spool time is rediculous and if the honda tuner knows how to tune a honda, with plenty of ignition timing a larger turbo will come onto boost just as quick as the smaller unit..................

b18c needs a minimum gt30 (500hp) roller...............and 0.82 rear........

good luck with it all...............i have done it before and would never look back from a t28 ...

pm me if u want any help
