Not much at all by itself. Maybe 3 hp if your lucky, it also really depends on what else is done to the car. Just installing a bigger TB is not gonna net you great gains. If you did it in conjunction with other mods it would be more beneficial. Like: TB + Plenum + CAI + a tune.

I look at the plenum/TB instal more as a throttle responce mod than a HP mod, dont get me wrong it will add HP but none that will be noticable.

i dont plan on doing the headers just because i dont want the headache of taking them out just yet. depends on if your having someone do it i guess. for me i just am doing my exhaust from the manifolds back. in the spring i plan on doin cai, tb/plenum. Its whatever you can afford i guess, but i dont know if headers give you great hp gains, but as said in other threads i guess the 2v motors dont respond well with bolt on's

Um, 3 hp ? Maybe that much at flywheel, but it won't be enough to make a differance between dyno runs.

I got 4 at the wheels when I had mine dynod..Then I put the plenum and got a total of 11...hp is hp dont matter how lil it is. regardless you will need these parts later on for better performance
