Cams will make the engine not stable leh... Well~ what is e management?

Previously having O2 problem with check engine light on but since the change. The light haven't come out for sometime already and will keep on testing just to be sure.

1.7" piping is enough for N/A engine at 1.5 & 1.6 not need to go until 2.0" that is what the exhaust shop owner tell me.

Anything above 1.7" is for cars like 1.8 and above. And max for N/A engine is 2.0".

Unsure about this fact as i got it from that owner.

Any cams can you suggest for good idling(almost same as original) ?

Added on December 11, 2011, 12:44 amI am using K&N filter now but it's the original size for my engine. If I change it into K&N mushroom filter, will there any different?

yerp..top speed 265km/h on this waja mivec

he claimed like that..

this is entry level yoko rite?

2 mid bullet increase top speed ah?

dei..i'm not that gila mau 265..i mau 200 enough..190 pernah dapat..

i 190 dah mati.then when it get slower,i hidup balik.wahahahaha

Blocked mulffler doesn't contain fiber if not mistakrn.. most midbox in malaysia is wit alot hole. Blocked muffler cannot b found in here..

so plates replacing fiber la?

ya lo.. 1 way flow..

errmm...dunno call wat but upontheskyriver said its call blocked muffler., so i also use same words lo...lol.. actually its mid box will alot of plates inside to cancel out exhaust noise n tryin to maintain d exhaust velocity... david vizard had tried use these type of midbox for pressure wave tuning by lettin d engine sees this mid box as atmosphere + tuned collector's length..

which picture? i saw the waja ones, he said piping is in original size that is 1.7inch...

ok la, i dont know about mivec / vtec...but for campro 1.6 with auto transmission need to use 1.6 / 1.7 piping, i tested already, anything bigger is ok, but you need to rev up all the time like a race car, just to overtake another car on highway..im not talking about top speed..with 1.6 inch or 1.7 inch piping you get some drivibility...

i suggest la you maintain your 2 bullet, and downsize your piping all the way to 1.7inch...or you go to exss work and get their opinion. 

aiyoo..inside the Blocked type muffler is like this   

You are KK person also? How to check whether the exhaust got leak or not arh?   
After I have changed the exhaust system, I still cant feel the different in pickup yet... Just top end and torque increase a bit only... Not satisfied enough yet 

Will fuel injection better power than carb?

Even just changing the head of carb to fuel injection also will increase power? How much will it cost?

weber... prepare at least around 1k include all tapak n etc..

This kind of thing is hard to say leh.... U ask them, if u r not satisfied, can u get refund?

Will after market carb cause the engine eat much petrol? I am thinking to change from
Carb to fuel injection. What is the sum of the price?
