Skunk2 intake manifold for NON-vtec
Don't LEGO build.
You have to do a lot of planning and research before getting into and IM.
They work differently with different setups. Once you have surpassed the intake, header and exhaust, there is no more bolt on performance. Everything else must be well thought out and thrown into one giant equation.

umm i know after intake,header,exhaust, that many ls owners have gotten good results with intake manifold,tb,ctr pulley,etc.

You, apparently, missed the point of "Lego build". In other words, you can't just slap a 70mm TB, a Skunk2 IM, a lighter Crank Pulley and expect them to magically give you horsepower gains.

Since you are willing to listen....some of this info is from articles in Team-Integra.net. An excellent source for Integra info, you just have to search around there, sometimes pages at a time, and you'll find what you need.
To start, you're going to have to figure out where your powerband starts. (So decide now if you want to change transmission or gears, cause they change that)
Once you've figured out where your power starts, time to decide a good length runner on that IM that will create maximum "ramming" effect at that RPM range.
You'll match that up with when the intake cam opens. The lift doesn't matter too much here. Sometimes you'll have to find some dyno sheets of cams to find out exactly when they make peak power. Most will supply a sheet of a "guesstimated" rom range. i.e. 5000-8000 rpm. And that will give you and idea. To fine tune the opening time of the intake cam, obviously cam gears will be essential to aid that.
The size of the plenum on the IM is also relevant to the setup. A general rule is that FI setups require a larger plenum size than an N/A setup. Some people suggest, as an example, in a 4 cyl. N/A setup, for peak torque to occur between 5k-6k rpm, the plenum volume should be 50-60% of the equvilalent displacement. Equivalent displacement = actual displacement
For FI equivalent displacement = home much volume of air is being forced into the engine.
Anyways, all that and you will have to tune fuel to go with it.
So, as you can see, if you want to be technical about it, it's a pretty extensive process. I don't expect you to get out the calculus books and start computing equations, but, if you're going to spend the big $$ on these products, you might as well make them worth your while.

Do you have fyno charts before and after to prove the gains and show what adjustments were made to get them?

Not yet i just installed it. I plan on putting it on the dyno soon after i get my cams, as for right now i have i/h/e with the manifold and you can definitiely feel more power in the higher rpms.

Actually you can.I know that a skunk2 manifold and ctr n1 pulley and 64 mm tb on my friends ls made a good difference.

Well, unless you guys **** out dyno sheets, you don't know that for sure. I'm glad your *** dyno told you it was a good improvement though.
Too bad people don't actually do home work and do major modifications that coencide with each other.
Personally, I could care less., Integra21 asked some questions, and I answered them hoping he would take in the information and want to learn more about how it's going to work.
Either way, best of luck to all of you. I'm done with this subject.

Someone needs to come up with a variable runner length IM, as rpms go up the runners get shorter. just like the VWs have. I would try it if I had the money and a CNC
Integra21: you should drop by team-integra.net but be forewarned that the environment is more committed toward self-help article/forum searching.
ScreaminTeg: is right on the money about power package and lego building. Too many people are getting caught up in the whole F&F and Super-Street misinformation that's been floating around. When you start to work on your car, you should have goals and understand what setup is most beneficial to your powerband.
Slapping on like say... some cams and IM because some people said that it was good isn't going to cut it. Understand when people say "FEELS" faster versus actually dyno sheet numbers (which I have to admit too will not entirely tell you the full picture but would be a better start than just what people claim). Understand gear ratios and what setup will best suit your powerband... for example, getting a tranny that is too long will drop you out of your powerband if your powerband is very narrow and located at the top.
Anyways... Good luck and educate yourself. =] Be aware of the information that is around and ask yourself if it's really the truth.
