I have a '97 Toyota Camry LE 2.2 Automatic and its stock but i was hopin to learn about how to give it a little more pep. I have a k&n wimp intake but it does the job and it was better than stock. I recently found the Injen IS2020 ram air, which looked like the only legitimate air intake on the market. It also seems that OBX is the only company that makes headers and exhaust for camrys. I was hopin to get to 150HP without major expensive upgrades and i'm not sure if you can do that without various tranny, valve, rod, and differential problems. Anyways, I dont know much so any help is much appreciated.

 

150 is a decent target.. well you have the options of:

Racing Pulleys ($200)
Air Intake (like that injen one) ($200)
Exhaust + piping ($350)
bored out throttle body ($250)

welcome and good luck!
