i have a 98 integra ls. im thinking of boring my throttle body and my intake manifold. has anyone done it and how much hp did it add. also is it pretty easy to do. if it is can someone tell me how to do it , like what do use and what mistakes not to make. thanks

 

I didn't realize you had to keep your throttle body entertained.

At any rate, I understand that you souldn't bother boring out your TB unless you plan to or already have done major engine work - cams, turbo, whatever. Just thought I'd throw that out.

 

I had my GSR throttle body bored out 6 years ago from AEM. If I can remember correctly, it cost me $175.

 

I know for a fact that not too long ago http://www.jgenginedynamics.com was boring t.b.s for $105!! Of course as far as you can take the stock t.b. is 4mm over (that is how much they bored it)... but on a N/A LS that is plenty. I would think that you would see a nice gain in the throttle response area.
