Help prelude weight reduction

I have a 92 honda prelude with a h22 and a 5 speed I want to make it lighter but want to keep the back seat and the a/c. What are the best ways to get a lot or horse power to. thanks

That's a really general question, but I'll do what I can. Removing the jack and spare tire would save you some weight. Also a carbon fiber hood and trunk will save you some weight, but nothing all that noticable. To add horsepower, the list is endless. Intake, headers, and exhaust are the three most common and probably a good start.
