ls throttle body???

ok- im currently running a d16z6 with i/h/e and i was wondering if it would be worth it to switch my d series throttle body for the bigger b series ls throttle body. is it that much bigger that it would make a difference? i should be able to pick one up from a local junkyard for pretty cheap and the install wont be bad. im just not sure if it would be worth it. any and all info is welcome. thanks

Not unless your intake manifold is ported to match. Kind of pointless if it's not.
