Based on what? That sounds way too big to me. If you can make 270hp on 50mm ITBs on a 3SGE beams revving over 9k rpm what would make you think the FA20 (that cant even safely sustain revs to 8k) would need TBs that big?
Edit: After some googling I am guessing you are used to Hondas. FA20 =/= K20. FA20 is lower revving and doesn't have the Vtec big cam to deal with.
