i have a 2005 EX and my next step in my modifying process was going to be a throttle body. the stock opening on my intake manifold is 66mm and through some small talk i come to find that the only real way to get power from an aftermarket tb is enlarging the diameter from 66 to 70 or something like that. if i go this route i am going to have to get my intake manifold punched out, considering the fact that no one makes aftermarket intake manifolds except kms, which i heard sucked.is any of this making sense or even worth my time

 

You could get your throttle body bored out to 68mm or 70 too, aftermarket throttle bodies can be expensive. From what i've heard it wouldn't make enough of a difference in power to be worth it unless you've done some internal engine work,likean aftermarket camshaft, stuff like that.
