I got all the basics (4-2-1 header, CAI, high flow cat) but i was wondering what would be a good hp gain i could do next. I will be doing a turbo in the future, but as far as a bigger throttle body or intake manifold i don't know what gains i would get. I am looking for at least 10hp more.

Well, if you have an EX, you probably won't see as much gain with a bigger intake manifold. You may see a little increase though. If you do go that route of getting a bigger throttle body, just get the intake manifold port matched to the throttle body. If you have an HX, DX, CXor LX, then you will see bigger gains with a intake manifold swap. People refer to the D16y8 (EX) intake manifold as the type R maifold of the D series.

 

save the money for the turbo
