ok. i have a 2000 civic si. i just swapped in a jdm b16a sir2. older motor, but a lot less miles than i had. anyways, so far i have aem cai, and am running an open exhaust from the cat back. I have the motor running about as good as it can be as of right now. what should i do next? the motor feels a little stronger than my old motor, i know it makes a little more power. right now im guessing i can run high 14's to low 15's with the set up i currently have. my goal for right now is to get into the high 13's, eventually lower. what would you guys recommend i do next? or what should my next few mods be to help me reach my goals? this car is daily driven, and i average about 35k-40k miles per year. i live in an emissions friendly place so im not worried about inspections or anything. so what do you guys think?

 

oh yeah i almost forgot. i plan to stick with the block i have now. at least while this car is daily driven.
