i/h/e

[schizo]

guys, i need your help. psensiya na, wala po akong alam.

what type (brand) of i/h/e would be the best for an a/t civic lxi? it's a daily driven car.

approx. how much HP would i gain from installing all these mods?

will this, in any way, have an effect sa emissions test?

for the muffler, what would you guys recommend na hindi masyado maingay during high rpm?

finally, where is the best place to get these mods installed? paki include na rin yung prices.

salamat!

schizo,

Meron akong OEM muffler galing Sentra GTS. Pero easily adaptable ito to any make baka gusto mo. Hindi siya kasing ingay ng sa Freemuff and mas malalim ang tunog. I just don't know kung may HP gains ka with this muffler. Php 2K only.

K&N is usually the best pero mahal. If you go with Simota, take good care of it. Never use high water or air pressure and use the proper cleaning kit at the proper intervals.

Most aftermarket intakes are CARB (California Air Resources Board?) certified, they will not affect your emissions in any significant way.

These mods are best installed in your garage by yourself. Madali lang iyan. Bonding pa kayo ng car mo.

you can get K&N filters and a FREMUFF or AutoXer's Mandrel Bent headers at 7.5k sulit ito and keep d stock muffler for no noise travel!!!

On my Civic VTi A/T, I got Simota Air filter (planning 2 get d K&N soon), DC sports 4-2-1, and orig. Honda Sports stainless muffler. HP gain, yes! ramdam na ramdam koang gain, but it increased my gas consumption a bit. siyempre, gusto mong humataw eh..... lalakas nga sa gas! but still nothing beats the manual......

i suggest that you get a free flow muffler if ur gonna install aftermarket headers and intake systems. if u dont, you'll feel the restriction of getting rid of the exhaust/waste gases of combustion which will result in that "pigil ang hatak" feeling pag umaarangkada ka. ganon kasi setup ko ngayon eh: simota air filter, jasma spec muffler, pero stock pipings. ayun, parang pigil sa gitna dahil added intake, pagdating sa gitna, sakal yung exhaust kasi stock 1.75" lang pipings ko tapos free flow muffler. to maximize power gains, or at least the feeling of power gains :mrgreen: , get the complete package na of I/H/E IMHO.

OTEP,
sir, thanks for the offer. i'll keep that in mind. anyway, i'm not sure if i'm capable of installing these mods. baguhan lang kasi ako. baka magkamali or may masira ako. hehehe.. medyo tight yung budget, so i don't have the extra cash for repairs (if ever).

fr3d3rick,
sir, stainless ba yung headers ni AutoXer? saan po located yung shop niya? also, magkano ang kuha mo sa dc headers?

ssaloon,
sir, sorry.. medyo na-confuse ako.. iba pa ba yung pipings sa headers itself? or are they one and the same thing?

guys.. thanks for your patience. pasensiya na kayo, baguhan lang kasi ako.

[ssaloon]

pipings yung pipe connecting the headers to the muffler

[wrecker]

i've read somewhere na if i change my pipings say to 2-1/4" i need to remove the cat and it would be hard to pass the emmisions test?

is this true?

[ssaloon]

i think hinde kasi i think may cat na kasama yun na bago eh... and one more thing, why would there be aftermarket cats kung di pwede lagyan aftermarket pipings?

[mazdamazda]

IMHO

don't mess with your stock pipings... lalo na IHE lang naman ang upgrade mo, you just really need to chage that when using force induction upgrades. if you really want to change your pipings hanggang 2" lang. you'll end up losing torque when you have oversized pipings.

if you want that sleeper look, filter, headers and port & polish ka na lang.

as for spark plugs and wires, you'd be better of with your stock ones unless you also change your ignition system.

[ssaloon]

depends sa car yung diameter ng pipings eh... kung 2.0L displacement and up, bitin ang 2" eh imho

yup, i agree with you on that... but his car is only a 1.6L

he can change that to 2" but it is costly as he'll only gain a meager amount of hp (and as i've mentioned, possible torque loss)

[ssaloon]

ang stock ba ng civic 1.75"?

[schizo]

guys,

would a budget of 16K be enough for an IHE upgrade (including header wraps)? :?:

[ssaloon]

ok na cguro yan, baka may sukli ka pa eh :mrgreen:

[crossback]

wat if Intake lang i upgrade (simota or K&N), headers/pipings & Exhaust all stock - meron ba SIGNIFICANT gain sa power?

[Ungas]

There will be slight as a pinch of gain, but not noticeable. But you will definitely feel money loss after buying it. :D

[empy]

as a general rule, pipe diameters of more than 2.5" are only effective for cars with forced induction. as mazdax2 said, you will feel some torque (arangkada) loss if you put this stuff on a N/A car.

while installing an intake is very easy, installing headers/downpipe/exhaust is not for beginners. you'll definitely need power tools, a lift, and maybe even welding/cutting equipment depending on your car's stock parts.

on a 1.6, i wouldn't expect gains of more than 15-20 hp - and that's if all the parts work perfectly with each other

[wrecker]

anong nga bang diameter ang stock pipings ng civic?

[icon]

I have a 2.2 liter vtec accord, anong ok na header pwede?

Allow me to express my opinion, but I think the whole idea of I/H/E engine modification is amiss. If you really think about it, I/H/E is actually the reverse order in which these mods have to be done. Thus it should be the other way around--E/H/I.

My reason behind this is that it is pointless and counterproductive to increase the intake capacity if the exhaust itself is restrictive--which it normally is if it is stock quiet, right? Afterall, what's the use of having a better, higher flowing, more efficient intake if the engine cannot expel the additional air and fuel out of the exhaust?

So if the car's exhaust is quiet(which it likely is, if it is stock and is in good condition), then the obvious system that needs to modded first is the exhaust. Only after the exhaust flow capacity has been increased will any improvements in the intake really take effect.

Now, as to the proper logical order of the modifications, if they are to be done on a step-by-step basis, I think the exhaust AFTER THE HEADERS/MANIFOLD should be taken care of first. This should be followed by the headers AND the porting, done together/simultaneously(smoothing of flow surfaces in the intake and exhaust ports), then finally the intake, which should be done last.

To recap, the order of the mods should be as follows:
1. Exhaust pipe AFTER the manifold(obviously includes the muffler, resonator, and everything in between the exhaust manifold and the tail pipe)
2. Headers AND head porting. The surfaces of the ports are smoothened and polished and matched with the headers and the intake manifold.
3. Replacement of standard air intake with Cold Air Intake or Ram Air Intake.
