Throttle body

a 65mm would be good for mild upgrades after that you might want a 70mm, but putting a bigger tb on a stock intake won't do anything. There are plenty of other upgrades you can do for the same cost as TB that will give you better gains.

Well heres the problem, i have a 300 dollar budget at the moment. Since i am buying my pully's. So the TB was my next choice of modifying, unless you have another choice next, got headers, cold air, distributor.

A full O/R exhaust system and gears are the best bang for the buck on an uncracked 5.0 motor. Gears are cheap just save a lilttle more for the install, it's something you'll feel SOTP instantly...

Ya forgot to mention my flowmaster exhaust which is o/r. And the other problem is its auto, hopefully in a year ill drop it for a t5 or keep moding the engine till the trans goes. So now i am stuck on what to get next.

$100 for summit headers (regular length not silly short headers). Best power gain for the buck probably. Next best thing, $:P that is, go get a different cam.
