Headers or Intake ??

Ok so I don't know much about cars... I have a 1995 Civic DX 2Dr and I was intrested in getting a little more performance & Hp for my little car... I know a short arm intake is a quick cheap fix, a Cold Air Intake is a little better... Headers I know nothing about really.. What's the advantage of a 4-2-1 one piece compared to a 4-2-1 two piece ?? Or a 4 into 1 ??? WTF is the difference ?? I'm fairly sure that if I want the desired results i'm looking for I should probably get both right ?? Any help/advise would be appreciated... Please speak normal english if you can, my car knowledge is very limited... I'm suprised I even know what I just typed...

Thanks...

depending on the header design youll get power at different points in the powerband...if you just want a LITTLE more power get intake header and exhaust...if your a little more serious about making your car faster there are more options...

Meaning the acceleration in different gears ?? I'm looking to just get more response when I press the pedal, in first or 5th... What do you suggest... Thanks for the quick response...

Also should i not even worry about any Mods if my engine has 140k on it ?? Should I just wait for the eventual swap ??

how much $$$ do you have? or how much are you willing to spend? about the header 4-1 will give you more power in low rpm and 4-2-1 header will give you more power in the higher rpm...so you can make that decision...most people with hondas go with the 4-2-1 design because hondas lack of torque

and generally a 4-2-1 is cheaper and definately easier to install...i would get the one piece so that you have one less gasket in your exhaust that could leak...

but honestly there isn't a lot you can do to make that stock non-vtec engine a lot faster.....sorry

That's not true.

Since you're a newbie though. Get an intake first. Then if you like get a 4-2-1 header. Note: 4-2-1 is for low end and 4-1 is high end. If you want to keep that engine and/or rebuild it you don't need vtec. There are other options, but it depends on what you want.

all that stuff istn't going to make that engine a lot faster tho....its going to help without a doubt, but its not going to make a huge difference....

The only way to make a D fast is to put it in a light car or boost it....

Schister66 is right...the only way to make a D fast is to boost or unless someone can prove me wrong

and in my 2nd post i meant the 4-1 for high end and 4-2-1 for low end

damn right i am....:p

Ok so I want to go with a 4-1 one piece for high end cool... Also what do you mean by "D"... DX ?? Thanks for your help guys :-)

what we mean by D is a D series engine...which is what you have now and is what most civics have without a swap

Seeing that I have 140k miles should I just wait to do anything before I swap ?

are you going to swap for sure...you could save your money, rebuld the d, maybe a mini me (nonvtec to vtec head swap), then boost the shit out of that engine!! You could make 300whp daily on a built turbo D.....or you could make less or more depending on your budget and goals....

bisi; nonvtec d15 and f22. yes its alot of money, but its still nonvtec. the only disadvantage to nonvtec is bad idle with high duration cams; if you can live with a high idle though it wouldnt be a problem. Hell, theres a guy with a D15B2 racing in a SCCA event thats pushing about 160-170whp; more than some b16s.

the best advice you will get, is...................................do a search.

I figure the swap is worth it seeing 140k is a lot (not in a honda I know), last thing I wanna do is put the $$ into it & my engine take a dump..

we still dont know how much you have to spend. is there anything else done to the car?

See as how you have limited knowledge of the automotive world, I would advise against a swap. Unless of course you can find a shop to do the swap for you. Are you looking for just a little more acceleration, or do you want to blow doors off of a z06? Ether way we will be abel to give you much better advice as to a path to take if you tell us what your budget is like. :smile: As to your original question i would say header, then intake, and if you have enough money a rear exhaust section. 4-1 header by the way. :cheers:

that was a good way to put it...:1:

Your car have a D-series motor on it, so it don't turn to and don't produce so high RPM power as a B-series. So I recommend a 4-2-1 to you, beacuse if you use a 4-1 header it will lost low RPM acceleration (beaucse the lost back pressure) (I have this problem now). Two piece header is just for a easier installation; the gasket should not leak.

And if the 95 non-VTEC intake manifold is like the 96-00 civic manifold, I really recommend to you to upgrade it to a 96-00 civic EX (D16y8) intake manifold, as with that intake manifold no matter if you use the best intake system (short ram or cold air) it will not do "anything".

Reaserch if this manifold fit directly on your head; I think it fit, but not sure.

honestly just get a damn header...it isn't going to matter that much...then get an intake...the Ebay ones work just fine! IDK what you have for power goals or a budget, but the ONLY cost effective way to make a D fast is boost.....

I think 4-2-1 header is better for a D-series engine. A B-series engine have a bigger bore so its produce more hp. A D-series engine have higher stroke so it should produce more torque.

And first intake, then header, then pressure regulator and VAFC (VTEC and air/fuel controller), and a y8 head...
Just logical reasoning, if you don't put more air (and fuel) into the cylinders, then what will go out through the exhaust port?

140k is a lot for any engine. "Refresh" your internals as: piston rings, bearings, oil pump and pickup, all gaskests, water pump, spark plugs, seals, igniton wires, timing belt, valve seals, fuel filter, etc. Also upgrade those components with a brandname aftermarket parts.

Installing performance parts in a 140k engine just will end in engine damage...

A D16 is very similar to a D17... My cousin had a 2 inch exaust system (cat-back) on his D17A2 VTEC, then "reinstall" the factory exhaust (I think 1.75 inch) on it and it really have better low RPM acceleration...

I install a 4-1 header on my D17A1 non-VTEC and it come to produce hp after 4,500 RPM... That's why my conclusion.

And sure, boost is the "fastest" and better way but more expensive.

Have u thought about an engine rebuilt?You know take it out unclog fuel and vacuum lines and take that nasty grease of it if u have some and u probably do....also another way that is recomended is you getting a new intake manifold....cuz air is free so the more u pack under the cylinders, the better..and while ure at it be good to get new spark plugs and spark wires..what do u guys think?

what are your goals for the car and how much do you want to spend......i could probably find you a good deal on a D series kit if you're looking to boost......they're not as much as you think if you really search for a while....my GSR is projected to cost me about $2600 max w/ a clutch, OBD1, Crome (pro?) and tuning on a dyno......most parts are new, but i'm thinking of saving a little and getting some that are "gently" used.....
