hey guys just out of curiousity if i wana mod an auto car, wat do i usually do 1st??

wat i tink i shud do 1st:
- buy grounding kit
- change sparkplugs
- exhaust change???

owh n if cn wif out tebo.. hahahha

if ders anytin else cn add oso r??

tanx 2 any sifu who reply.

Em 1st thing to mod would be to change the gearbox to a manual one

What is tebo?

http://forum.lowyat.net/topic/273123

how much is ur budget??...

well.. a drop-in K&N Filter would help.. then removing the cat and changing to s-flow muffler perhaps would be the next step..

then iridium plugs and changing to better cables (note: bigger mm doesn't mean it's better).. voltage stabilizers and grounding cables will help..

if injection, then u could add some management, perhaps E-Manage or Unichip.. then maybe a fuel pressure regulator...

then try to lighten the car a bit if power is ur quest..






then of course after all these mods, u'll be searching for another auto gearbox to replace ur cooked current auto box.. and in the end, u'll convert to manual trans..

change to s-flow ekzos system 1st

Most important thing is NOT to change exhaust. Auto cars with loud exhaust r horrible. Make the car sound like a motor boat!

hahaha just wana haf a lil fun.. sorry ar.. turbo....



4 now r is below rm 1k..


owh so dat means auto cnt mod eh????

K&N filter is d best in d market?? if compare 2 HKS??





hahaha owh yah man i agree. auto wif big exhaust.. even a lorry would lose wif d auto's exhaust sound.




must really change r???


i like my auto car.. hahahah

not really need to change to manual one, it cost about RM10k to change from auto to manual for some car, and not every car gt auto and manual gearbox for them, some auto car hard to find manual gearbox.

perhaps u should start from the most basic mod, air intake, sparkplug, voltage stabilizer, and exhaust...

depends on wat exhaust u mod, dont mod those exhaust with lousy and noisy sound, in the end, the car beside u will just laugh at u

Lighten Crank Pulley, lighten rims, remove cat-con replace with bullet approx 15"~17" (same inlet/outlet diameter), Adjustable Cam Pulley tune to advance (sacrifies the top speed), piggyback n tune it a little lean (from 14.7 to 14.9 or from 13.5 to 14.0) from 1K to 2.5K rpm.


ooh yea...not to forget ur drop in air filter with CAI.

i dun understand cn u elaborate??

hahah noob here...



ok lets say i wana mod d exhaust.. i say oni r, wat is d best brand of exhaust?? n if i mod ders no effect or any specification of exhaust type eh??

if you wanna change your muffler, S-flow is the way to go....

leave it, as long it's auto it won't show much HP difference within 1k budget.

cat-con = catalyst converter

15"~17" = length of bullet or length of resonator

Same Inlet/Outlet = the diameter of piping on the bullet is same diameter for both end. And it's the best to get same diameter of bullet in/out with standard piping diameter.

Adjustable Cam Pulley = to replace stock non adjustable to adjustable, where the timing belt installed onto.

Tune to advance = shifting the powerzone to acceleration or pickup.

Tune to retard = shifting the powerzone to top speed.

Piggyback = interceptor of data that return to ECU, simple terms is a device to lie ECU.

Lean / Rich mixture = means air to fuel ratio 14.7 during combustion. 14.7:1 means 14.7 (air): 1 (fuel). Lean will give better and lighter acceleration but it will blown ur engine, that's why i said "a little lean" in the low RPM from 1000 to 2500. Where normally cruising on highways is 3000 to 3500, so leave that rpm rage standard.

if u own an auto, no nid to mod la, very darn expensive...

the best thing u can do is juz adding some stuff, like vs, grounding, acp etc2...

if u wanna get performance mod, go for manual, thts it..

or u can go for other mod, like exterior n interior mod, for autoshow

hahahha.. just wana know cos saving up 2 do bigger mod.. bigger mods not rite now lehh.


owh so basicly auto not advisable 2 mod r?? but small little mods cn r??

like say ok if i mod air filter, sparkplugs wont haf any bad outcome 2 d engine eh??

TS try PM coldfusion, his charade is auto but damn power!

im guessin the car in question u wanna mod is ur chevy aveo, rite?? for only 1k, i suggest u juz keep that money.. thats not much u can do 2 boost up the performance of the 1.5L etecII engine anyway

instead of wasting ur money into the basic mod, why dun u jaz change to manual? make sure u find a short ration one. trust me, the result is better than any of the basic mod they mention.

check what is ur transmission stall speed, try to source stall speed below 3000rpm as it's still good for city driving. The higher stall speed means the higher RPM u can rev during the launching from stand still.

Alot ppl said AT is suck to the max in acceleration, but those american use it for 400m drag race....

see their car also diff ma. haha muscle car.

hehehe.....our car also got muscle wat....but our muscle is at the roof top.

reading this makes me laugh.. bro, changing exhaust doesn't mean it has to be loud.. it juz gives better flow.. and, for an auto tranny, u'll be using the "S-Flow" type muffler, which in return already reduces the noise.. there's a lot of aftermarket exhaust out there that are silent.. don't go for the "RM130 Semua Siap Pasang" package la..

what i'm using for my Gen-2, changed R3 header (removed the CAT), bullet, and Speedworks muffler, no noise at all inside cabin.. outside, when u pull, it sounds like a turbo engine when the internal wastegate routes the gas through the exhaust, which is sweet for me.. it's silent if the throttle is depressed <50%..

dyno tested it, before and after gave me an extra 9HP at the wheels.. that is without the K&N, and with, adds up another 2HP..

not to say it cannot tahan mods, it can.. but our proton gearboxes only can withstand to a certain HP increase before it fails, which is not much btw.. that's why American or European gearboxes have horsepower ratings, i.e, till 550HP etc..



p/s: i destroyed 7 auto gearboxes in my 1st car, which is a 1990 Proton Saga 1.5i (4G15) [personal R&D purposes], before i finally swapped to VR4-RS (4G63T) engine..

lol
best still is no exhaust after extractor. that is proven to be the best

or straight piping to the rear without any bullets or midboxes - they ruin power at high revs if your car is setup for high power at high revs.

I run without bullet before, the high rev is superb but i'm so shinning on road like GOD Of WEALTH to PDRM.

i don't get your analogy there O.o

bro when u changed to gen2??... ur satria vr4-rs sold adi??... i havent sat in ur monster before leh...

no for auto tranny...

Bodykit and HID 1st

S-flow exhaust, so far i heard many review that this exhaust r very silent.

the mod i think u should do is
change sport rims,the interior,bumpers,exos pipe.
btw i asked the mechanic the price and workmanship to change the transmission from auto to manual is only near to rm1k only

intake, exhaust, ignition, fuel management

drop in air filter will help a lot due to higher flow of air

exhaust, if u wan to b silent, add more mid box, use s-flow muffler to gain more back pressure for yr auto gearbox since u;re n/a engine

change a set of iridium plugs is more than enough

fuel management, emanage ?

n also, take out everything unnecessary such as spare tyres if u always travel short distance

hahha.. dats rite!!!

hahah .. hmm true oso but if i changed manual its almost a diff story rite?? not 2 sure..

hahah. owh ok ok.. dats true liao.. i tried it b4 very fast pickup.. feels like rocket taking off ... hahah i oni do dat wen d road is empty after toll.. after dat tak brani nk tkan lg.. hahahah


change 2 manual?? wat does it include??? cos i tink r finding parts wont b dat easy 4 my car.. huhuhhu . but i tink 4 kenari auto 2 change 2 manual i tink its around rm1k..




i tink i read somewere s flow is for auto while straight flow is 4 manual rite?? but oni a specific straight flow cn b used on auto rite??? ..




ur gen2 auto eh? sweet sound man... dat means d CAT is not a gud ting 2 haf eh??

i also have a gen-2 for daily driving.. but now my sis juz got her license and she's using the car.. yup, sold my satria already, now driving a stock standard auto waja..

Added on February 19, 2009, 2:17 amyup.. the catalytic converter is kinda like a filter to filter out toxic carbons and for emission regulation purposes.. if u take take out the cat, point it to the sun and look through it, u would only see a hint of light.. that is how much pressure flow is being blocked by the cat.. so removing it would give u a big improvement..



straight pipes on an auto tranny is a big no-no.. u need the back pressure of the exhaust gas for the low-end torque..

This post has been edited by termignoni: Feb 19 2009, 02:39 AM

I'm using manual... Is there any other alternatives for straight flow? cuz straight flow is reli noisy and 'suck fuel'... i think...

Air filter.. drop in? how about open pod? Which is better?

Cat-con filters the air right? Is it legal to remove it?

owh ic but if we diy is it easy 2 do?? or we still need 2 send d mechanic??

of coz send to mechanic.... unless u have welding machine at home and ur welding skills is very good to guarantee no leak...

if u wanna change manual also, parts r not gonna be easy 2 find.. as u know, the aveo comes here only as auto only..

hahah owh ok ok.. i dun haf welding machine but i got super glue..


yah lorh.. ok other then d aveo, if i change any proton auto 2 manual is easy rite??

bodykit nearest 2 aveo is jazz rite?? HID lights is legal or not r??

I'm not talking about loud sound levels. I said it sounds like a boat coz of the auto gearchange. It's an unavoidable thing with autos coz the auto gearchange makes the change in exhaust note sound damn lame.

Added on February 19, 2009, 10:36 amAveo got the optional Aveo kit from Chevy oso nice mar. Why not get original Aveo kit instead?

This post has been edited by ianho: Feb 19 2009, 10:36 AM

dat is my 1st choice... but where 2 get.. i dun knw were 2 get d bodykit.. d aveo bodykit damn nice man..





d white 1 damn nice.. but i dun know were 2 go.. huhuhhu..

Y not go to a Chevy dealer n try asking them. I'm sure the fellas who have the optional kit last time will need replacements too n they probably go back to Chevy for it or mebe they can tell u where to go buy it coz the Aveo is not sold anymore.

seldom see people mod chevy

more like a family car to me

TS Rm1k u can change cap ayam s-flow exhaust system, if u need branded then go for chop shop. good luck!

my iswara family car i also mod lah...

but if u have a silent exhaust, then there wouldn't be any noticeable exhaust note when the gears are changing..

however, there is a way around that.. lift up the throttle right at the moment the gears are changing, and then depress it again.. it'll sound like a manual..
