alright heres my say about this....
if you got money and 270ish horses at 9000ish or 10000ish is enough with u then go NA for sure
if you got money and 300+ hourses at 8200ish is what u want then only boost will help u out
if you got money u need to dyno tune that sucka with a hondata ecu(recommended), because the best ecu is custom programed for your individual setup
if you said yes to two off the above then u should allow some green to flow this way
as for TB's don't don't help for shit interms of rev's
personally i like to go NA if i can afford it because individual throttle bodies look and sound so nice, almost better then sex
