If i were to get a bigger throttle body would i have to get a larger intake to fit around the throttle body?

Whats the gains when getting a better throttle body?How much HP do you normally get?Is a bigger throttle body really needed?

Would i be better of getting a bigger throttle body or an better Intake Manifold?

And also what is a good brand for an 92 LS and how much should it cost and whats a good place to get one from online?

 

I've seen dyno charts on a 98 GSR with jg throttle body and it got 5 whp and 4 lbs of tq,whic is not a bad bolt on.I don't think they had to make any fabrications.

the place where a larger throttle body is larger is the inside diameter. they shave the inside of the throttle body out, or if you get an ITR TB it comes that way

it is a good idea (for better flow) to have the intake manifold inlet ported to match the new TB diameter, it is with this that you will see the best gains. you can take it to a machine shop and have them do it, or if you feel confident with a dremel tool you can try it yourself, but consider highly having a spare...

Or how bout a 68mm, or even 70mm unit from BBK or Ericks racing?

what would the power gains on those be on a Hi compression Teg with the Skunk@ manifold?
