wow ok thanks so knowing what i have.. i know this sounds really noob like but what can i get that can give me... say 10-20whp gain? i will go big later, i would love to get a B16 and turbo that, but like i said, cant because of my financial situation (only 19 and goin to college).

 

B16 is an overrated torque-less engine. If you want B-series, get a B18, that's where it's at.

Intake, header, @ exhaust would get you about 10-20 WHP (probably closer to 10 than 20). Intake manifold and high flow cat would be a good idea too. I read that a good intake manifold makes for a pretty nice gain if you have done intake/header/exhaust. The high flow cat would finish it off basically and give you a few more WHP.

 

thanks! thats what i was gonna do and you sayin that really makes me wanna do it and seem worth it

 

Those mods don't give very much power individually but they support each other. For example, if you have just an aftermarket intake manifold it's going to gain a little bit of power. If you have just an aftermarket intake it'll add just a little power. But if you add both, they complement each other and restriction throughout the entire intake system is reduced.

You can also swap on a bigger throttle body (don't go too big... I would recommend staying around 60-64mm... go too big and you decrease your air intake velocity... the key to throttle body size is keeping a good balance between intake air volume and intake air velocity) or have yours bored out. It won't help a lot but it will help some. Don't waste your money on expensive aftermarket ones, just swap on a bigger one from another Honda engine. Your stock one is 56mm.

Here is a list of them: https://www.hondacivicforum.com/foru...ead.php?t=3659

Most, if not all, of these are interchangeable (bolt-on wise). Some have different sensors on them than others though so make sure to check first that the one you are buying has all the stuff yours does.

 

ya i totally understand that. too big of a intake will actually not get enough air. kinda like the whole water hose thing. bigger hose vs. a smaller hose kinda thing. and i have an intake right now so the intake manifold would help me, and it seems like if i get a header with new piping, hi flow cat, and muffler that they would all help each other again.

now throttle bodies. it seems like a 58mm or 60mm would be a good jump. but are the bolt patterns and everything like that all the same?

 

I'm not too knowledgeable about the throttle bodies. I've been looking at them myself and I can't tell which ones have all the same parts on them. I believe the bolt patterns on D-series, B-series, F-series, and H-series are all the same

 

i understand the physics of why it would seem that a bigger TB would add HP, but my tuner and i agree with trust; dont waste money on an aftermarket one when an OE honda TB will suffice. i have not, and will not waste my cash on a bigger TB, mainly because the gain doesnt justify the cost. if u have an air intake already installed, next step for me would be a good filter (i bet u could use a nicer one), intake manifold, header, and FULL exhaust. in that order, but thats just an opinion. as trust stated earlier, a tune isnt necessary, your ecu should compensate somewhat for the mods. if u plan on seriously modding the car in the future though, hondata is always a good bet as far as ecu tuning goes and it wouldnt hurt to go ahead and get familiar with it.

 

thanks for all the advice guys, thats really helpful, i have an AEM intake with a AEM dry filter that when clean vs. dirty makes a huge difference. so should i get a different one? and if so which one?
