Whats next?

I bought a aem intake, a magna flow exhaust system, and a obx header. Where do I go next to upgrade. I don't want to put a turbo or supercharger in and don't want to put a different engine in but what else can I do to increase horsepower?

hmmm well help us out some, we will need to know what type of tiburon you have, and the year.... Do you have a V6 or a I4?

97 tiburon FX automatic

ok i4 then.....

well, I would suggest you take a look at the diffrent links posted for engine mods. Something you might want to consider if modifying your fuel delivery system or adding cams and other little engine stuff like that. I agree, turbos cost too much money, but damn they sound cool.

you could get lightier pullies and wheels wont add hp but free up a few
