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 ?

which one gives better performance ? or if change both then double the performance la 
Btw if change exhaust manifold & put in open air pod intake system can increase by how many hp ?

2.) Remove Cat - Con
3.) Chg air filter to  open-pod type. (Apexi Dual Funnel / K&N)
4.) Ram Pipe for Air Filter, looking for heat resistant one - (Any idea on brand and price?)

sifus here. wanna ask

my car benz 1999 A160 the Catalytic converter been taken out since last time service my car engine overhaul and that thing said dirty stucked and need to take out in order the car to start and move. now, as the quote said that thing doesnt contribute anything to exhaust noise, then how come my car now when revving i can hear noisy sound under the engine/the place where the catalytic housing area.. the workshop said they take out the filter inside it and seal it back.. So my question is, wad should i do? change a new 1 or send to workshop cut it out and extend then seal it connect to the exhaust so it wont hav the sound.

or change a new 1? any idea how much? and also now the exhaust damn smelly. perhaps it really bad to the environment.

had tried asking JFA today about the piping for my car+centre bullet..stainless steel type..they quote 800bucks!
aiyaa...but,anyone had tried JFA centre bullet?is it good?

roughly how much for a K&N drop in filter for wira injection?

hmmm any suggestion for neo's open pod filter?

Serious leh,. car needs more satisfaction ler~~huhuhu

i wanna confirm 1 thing... i juz changed my muffler... and now thinking of removing my cat converter and replace with bullet... my car is saga blm

my question is:
where do the sensor located? on d converter or before it?

hey you guys
been reading alot about how to increase low end torque for my 2008 iafm gen2 1.6//

i recently brought my car to speedwork in pj. had the whole setup change to hotbits - full exhaust system change there. change the air intake as well for the open pot k&n. well definately lot of changes in the high end power but  i loose alot on the lower end. i lost my low end power.

so any sifu can tell me what should i do to gain back my low end power or gain more lower end power?

as you know the whole hotbots setup exhaust has no back end box, its a straight end flow from the center. should i install s-flow muffler?

or what should i do?

In the first place, just use a lightened crank pulley will do....... Sure to improve low end performance......

You looked under the car?
