toyota altis 2004

[anne kelly]

hello guys!

im very new here and about to end my college years. i know little about cars although i have friends that are into it. hiya ko lang mag ask and ask.

my family recently bought a toyota altis 1.6e. although it is a reliable car, i would want it a little faster sana. the hp rating is somewhere around 116.

what is the cheapest way to increase its horsepower?
what is the safest way to increase its horsepower without going to the extreme, say, replacing the whole engine? (sowi po, wa me alam).
;)

thank you so much.

imho, it's a brand new car...don't mess with the warranty B).

don't resort to extreme mods -- esp. if it's the *only* family car B).

pero to answer your question...changing to aftermarket air filters would be an option...pero ewan ko lang kung magiging noticeable ung added hp

[Ungas]

Simple modifications on your cylinder head will do wonders. Though not noticeable aesthetically, but performace wise, you'd edge the same engine.

[benchph1]

yep...even the combination of the intake, headers and the exhaust upgrade can only give you an average of 10 hp increase on most cars....what more if its the intake only.

changing to fully synthetic oil is another option :D

[ebbfolls]

116 hp is already a powerful lot, and I doubt a newbie could efficiently, if not safely, handle all that power (no offense). That car could effortlessly leave all but the fastest of traffic in the dust, even with the a/c on. What do you intend to do with the car, if I may ask?

[anne kelly]

thanks guys for the replies. they are eye openers for me.

i actually just want to increase the hp to approximately 10 hp to bring the rating to around 126. my girl friends drive civics and galants (mostly modified by their kuyas) which i know have higher hps. I just wanna bring it closer lang sana. I also dont have a kuya. it was gift from dad and i dont wanna "ruin" it yet. :worried:

how much would a cylinder head modification cost? what would they do actually? further, whats a fully synthetic oil? whats the difference between that and the factory ordinary engine oil we use with toyota?

sowi po uli if im dumb with these.

It all depends on what the mods are, some may fetch to a couple of thousand pesoses to hundred thousands.

Some of the mods that I could remember as of now are: stress relieving, multi angled valves and seats, magnetic tipped, new cam design, adjustable cam gears and so on...

since you are a newbie when it comes to cars, do it a step at a time. btw, don't go messing your car around too much as it may void the factory warranty.

you could try to fit in a free flow muffler to you car. does tom's carry a bolt on application for the altis? noise will definitely increase but that's the downside of HP increase.

next is a drop-in air filter from K&N. am still also not sure if there is already an application available for the altis here.

next are headers. you can opt for custom built ones from the various shops around manila like fremuff, smt, etc. again, noise will definitely increase.

those simple modifications will not even cost you 20K.

if you want to take it a bit further, go for a cylinder head port & polish at autoplus. their stage1 application will cost you 10K.

[anne kelly]

thanks ungas (?, peculiar name) and mazdamazda.

the 10-20K, yes, but the hundreds of K, I cant afford it. dad will kill me.

my idea is to increase the hp "underneath" without being noticed externally (i.e. exterior mods, added noise). this being so, can i prioritize the drop-in air filter from K&N first before the free flow muffler and the headers? if yes, how much would it usually cost?

if not, is the addition of the free flow muffler really that noisy? i dont wanna sound like ex-bfs pathetic noise display broom broom broom (as if thats appealing to a 1.6L car or less). i hope you know what i mean.

ebbfolls was right. the altis is a powerful lot na. i just bought the latest C! magazine. the 2002 model is still one of the top dogs compared to other 1.6L cars. what more the 2004 model.

thanks really guys for sharing your expertise.

u can look it up here:

dunno any K&N dealers here though...also consider Simota

Be advised that although they say it's washable, you have to buy a special kit to re-oil the filter after you wash it(the gurus here can probably offer more advice on this) ...but they do promise trouble-free operation for the first million miles, so i guess it's a bit too early to worry about that ;).

[Gambit]

Hello!

For those who had already modified their altis stock air filters to Shimota Twister air intakes; Just want to know, how they had handled the built-in air flow sensor.

Most of the Toyota mechanics at the casa that I have talked to say that changing to open air filter would prompt the engine malfunction indicator to light & that it may damage the computer sensors.

Totoo ba yun?

Thanks in advance!

[mazdamazda]

generally the order of your upgrade should be: Intake - Headers - Exhaust. thus the term IHE for stage 1 mods.

for the K&N filter, it will usually cost about P3K and up. i think OTEP is selling those, just PM him... or go to autocentro in cubao...

as for the free flow muffler, some of them are not that noisy. just stay clear of those straight mufflers without a body - those really are a noisy. if you want, you can scout banawe for surplus mufflers from apexi, tanabe, spoon, etc... have your stock muffler cut and weld the new muffler in. a surplus imported / branded muffler will just cost you P5K. a brand new imported / branded muffler will cost from 12K - 25K. locally manufactured mufflers are also sold at around P5K, some of them are a-ok for the price.

btw the 2002 and 2004 models are just differentiated by some aesthetic upgrades. the engine and body are still the same - thus performance is still at par with each other.

some of our members * protegetech had some problems with simota filters. the actual filter detaches from the main body and the filter holes are a bit bigger.

with a drop-in washable foam filter, you have to clean it once in a while (every 7.5K - 10K kilometers). there's a special kit for this. bought one for P900 and i think is good for at least 4-5 cleaning. you first spary the cleaner, then rinse off the dirt, let the filter dry out naturally, then lastly apply the oil. just follow the manual.

MazdaMazda,

The proper order for a minor power modification should be exhaust, headers, then the intake. Stock cars usually have better intake capacities than their exhaust systems give them credit for by reason of noise reduction. The act of quieting the exhaust is the primary limiting aspect of an engine's power capacity.

Next in line would be the exhaust manifold. The idea is to make sure that the engine has the ability to expel the exhaust gases before the intake is modified to allow more air-fuel to be crammed into the combustion chamber/s. Modifications to the intake return nothing unless the exhaust is capable of expediting the expulsion of the additional charge.


Anne Kelly,

I suggest a deeper sounding exhaust should do the trick to keep your car "in" with the crowd of your friends' cars. Any hp increase you might gain from additonal mods could easily be overlooked by the many other factors that make a car fast. Besides, I doubt the main reason you go hanging out is to compare rides, much less, swap performance figures with your friends.

[Ungas]

anne kelly::: For 10K you can have it port & polished, adjust & set multi-angled valves and seats.

I saw Fusion R has some performace exhaust that doesn't sound like a jeep.

[anne kelly]

thanks guys!

so, should i go for the exhaust first? any actual brand suggestions that you personally use and recommend? particular store selling? how deep sounding should it be?

sowi guys if i ask very basic questions. its better asking humbly than boasting with nothing.

[Ungas]

Don't waste investing on those cheapo fart muffs. Where the sound is big at idle but gets choked when revving hard.

[Poops]

I checked the K&N site, i did not find a drop-in replacement for 1.6 Corolla. There was one for the 1.8.

[gearspeed]

Ako rin naghahanap ako ng deep toned na muffler pero maliit lang hindi nasa 2.5"-3" yung laki ng muffler..

Any guys wanna suggest kung saan maganda magpa custom made ng muffler?
