What is tebo?

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..

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

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

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.

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

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

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

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

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....

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

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..

yup.. 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..

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..

Aveo got the optional Aveo kit from Chevy oso nice mar. Why not get original Aveo kit instead?

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!
