how to get 20 more whp???
alright guys here goes, i went and had my car dynoed in like march and at that time i had Injen SRI, DC 4-2-1 headers, AERO 14" resonator (not really for power but it effects exhaust flow) and trd exhaust and i dynoed at 160 whp and 161tq which i thought was pretty good, i have a solid torque curve from 2500 all the way up, but i'm looking for a little more pep so i converted from SRI to CAI and got rid of the trd exhaust and picked up a greddy evo 2. haven't been dynoed since but i can feel its a little stronger not by much though, so i'm looking to upgrade, so what should i do? heres what i was thinking
getting rid of my dc sports headers and trying to get my hands on a set of MMW headers and s-pipe because from what i read those will get me the most power
either buying or having a custom made 2.5" midpipe made at an exhaust shop
and adding a water/meth injection to my car either devils own, snow performance or the AEM one
i'm looking for around 180whp because then i'm cutting into SI and type S territory i'm not looking for crazy speed but enough to hold my own and pull a nice 1/4 time
i know this can be done to get to 180whp, because a friend of mine had a tc with injen cai, i think he either had MMW headers or Alphawerks, or are they the same? and a full 2.5" magnaflow exhaust and he dynoed at 179whp, he still has the dyno sheet and i'm working on getting it so i can scan it
also i dont want to be too loud but it basically goes the louder you are the more power...well sometimes...so can anyone think if how i should have the mid-pipe built after the s-pipe to still make power and keep the noise down? thanks guys!!!

no really the pulley will give you like 10 whp, thats definatly something to be at the top of your list. Having a 2.5 custom mid-pipe built with a big resonator is a great idea too!

Port and polish your head and get a stage I or II cam and get high compression pistons.

Yea I had a fuel management but I recently sold it bc I wasn't s/c anymore (I kno I shoulda kept it but loooooong story) I'm not looking to spend too much money so maybe I'll avoid an engine management because I'm not mesisng too much with the a/f's nd such so I'm leaning towards upgrading headers, full exhaust and possibly the water/meth as of right now, I'm also going to consider a pulley set and the cams, I'm still looking for more input about the header thanks

if you do cams you're gonna need tuning
the pulley should be a must but I wouldn't do the water/meth if i were you. And really changing the header isnt worth the hassel for 1 or 2 hp at most. If you really care take care of it after everything else but it should be low priority, the one you have now is fine

Yea I gotta see if I can get my hands on a mmw header for a good price, another reason I want it is cuz of the s-pipe as well, also batman jw why you say to avoid the water/meth injection? From what I know it offers better cooling, helps clean your motor and as a biproduct you gain some hp I'm also going to do some research on the pulleys
