well just to let you know, i'd never build a b20, not worth the effort for the results...i'm not a newb, and i have a pretty good idea on what i'm doing when it comes to honda's, and i know alot...but i haven't heard much about the b16a w/turbo application...i know that b18b is great for turbo, and honestly i've been back and forth between them...the only real reason i like the b16a is because, if i decide not to turbo down the road for whatever reason, i can always go N/A and still keep up the ponies....i mean i know it's good to plan for the future and all, but turbo is really far down the road. this isn't going to be some kind of half hearted effort....i'm doing it right...before i even think about turbo, i'm going to have pretty much every bolt on cept nitrous....so inreality, i think my best bet would be the b16a just for the fact that i'll be able to play with the fuel/vtec combo and tune it right to get some more ponies...but thanks everyone for your suggestions
