I doubt it.  Maybe you could just get someone to help push the car.  ;D
Gosh I'm witty!

In combination with other mods the bigger bore throttle body is worth it, but on its own, I would say no. Now if you got a header, and ported out the head and did some intake work, you may find it worth the bigger bore.  It has to be part of a package, its no wonder mod!

yeah for $350US I don't think you get much increase,  for $350 you can get a pile of Type-R stickers ;)

I've heard some say boost the 92 horses to 110-120 but others mentioned not that much

If you go on PFF you will find thousands of threads, some suggest Cam swap, check it out. Was never intended to be a powerful engine and there are restrictions, plus with gas prices may not be a bad idea to mod for mileage.

CaddyRob is right; it will only pay off if it is done in conjunction with other mods that create freer flow - head porting, maybe intake manifold porting; headers or improved exh system; and a CAM to make the engine breathe deeper.  By itself (if you go TOO big) it might even create driveability problems - air velocities at idle and low spd might not be high enough etc.
Good luck and keep us posted on what you do and how it turns out!
