my extractor when buy the colour is stainless stell colour...then after 1 month usage it become like bronze colour sometimes i can see blue spot...what is this means?

urs is a chromed up extractor, once heats up, it will turn blueish brown and in the end the color will fade

is it good? afraid it will blow someday coz got blue spot like high degree fire

no problem wan la.. my white steel also become brown adi.. just change of color wan..

zilole9729: about the piping, must ask the mech at shop about the size.. i think is around that size for kancil coz my kelisa is 1.6 inch piping.

is it true if use 'short' type bullet will gain more pickup?

sum say yes, sum say no..

but definately short bullet sounds louder.

Dear all seniors,

after reading 26 pages, i guez wat i can do to increase the performance for my Wira 1.5 (A) Carb. is as follows;

1.) Change ori extractor to powerzone 4-2-1
2.) Chg air filter to at least aftermarket drop-in or open-pod type. Powerzone air intake manifold, any comment ?
3.) i think wira stock muffler is already s-flow type, rite?
4.) is ori exhaust pipe ok or not ? need changes ?
5.) What about ignition system ? any effect in terms of power & FC performance ? What can be done here ?
6.) Last would be to replace stock camshaft to powerzone camshaft ?

Wonder how much increase in perfomace would it be after done all these upgrades ?

Can advise a little bit more ?

1) correct
2) Powerzone is a reputable company.. better pick their items.
3) Yes, stock is s-flow
4) Depends.. u wan top speed or acceleration?
5) Change thicker spark plug cable and change to Iridium spark plugs (just my recomendation)
6) No. Do not change camshaft just YET. Changing to racing camshaft is the last upgrade possible.. like oversize piston, change compression, etc etc then only can change camshaft. or else.. u'll just gain 1-3bhp and 1-4Nm torque.

After all those upgrade stated above, ur car can feel like 1.6 already..

5)Dont bother
6)Ditto

Heres my advise,
-good quality extractor,piping can remain same,follow ori route (dont oversize too much,1.6" is good for stock engine),straight thru muffler.

-High flow,good filteration air filter. Apexi dual cone recomended

-Do up your handling such as stiffer suspension,shorter springs and anti roll bars.

-Engine management

I think the intake is only for fuel-injected models...

you mean the air intake manifold is just for fuel injection engine is it?
aduh ! I didn't know that ...

Added on December 5, 2008, 5:17 pmNot quite sure about No.6, what u mean is if I chg the camshaft first I can only gain 1-3 bhp increase is it ?
Correct me if i am wrong.
I saw in powerzone website, they have this thing called "POWERZONE 4G15 STROKER KIT (1600cc)" if i straight go for this kit, then end of story liao lor ? no need to go thru so many process, can I ?

if you wanna play camshaft, better port the head and do the intake as well as an oversized TB, finish up the combo. cam pulley to fine tune the camshft (optional but recommended)

Bottom block you can do later. If your car is a 1.6 to begin with, the head combo itself is very effective already

i got a ques here... if i modify my 4g15' header, will i see the power increase? by hw much bhp?

few bhp only.. but u'll feel the difference

u mean exhaust header??... depends how u modify it....

header as in extractor?

header can be intake manifold or exhaust manifold...

3hp

dynoed before??

Just a rough estimation
