Throttle Body Question ok i have a 1996 Trans am with Lt1, borla cat back, k&n cold air intake, longtube headers,ory, short throw 6 speed, and i was wondering if u can get a bigger throttle body with just those mods? if so how much bigger without having to do anything else? 52mm? 58mm? i am just curious about getting a bigger throttle and what are the gains with one?

You can get a bigger one any time you want lol Do you need one, nope. Not till around 400hp technically. You'll probably want a 52mm around 325hp. You'd notice throttle response right now, that's about all.
Just when I thought the TB questions were gonna chill for a while! haha but its ok. The stocker is supposed to be good for up to 450hp. You will be essentially wasting your money by getting one right now. I would wait until heads/cam come into the equation. I have a cammed car but still running the stock TB myself b/c its probaly still a waste for me. You will get tad better throttle responce but also if you say slapped on a 58MM I wouldnt be suprised if you felt like you lost a little bottom end. Also a 58MM TB will require the intake manifold ports to be opened up to fit it. I vote for spending that money elsewhere maybe on some suspension, Im sure the wifey will still bitch about that lolol

There's always 1.6 ratio rockers, or go further (but more complicated when it comes to installing) 1.6 ratio Roller Rockers. You probably get 5hp from the 1.6 ratio and another 5hp from the roller. Since usual gain is 10, I figure at LEAST 5hp has to be from the increased valve distance.
