act i started this thread cause the main problem tat im worried about is wat jinkl just mentioned..jz wana confirm whether its true or not..since its like tat wihtout hi cam so no point to install it..instead of spending on adj cam pulleys maybe i'll go for fuel regulator or spend smart on sumthn else

 

[raja_emeperor]

its all depend on what do you want from your car, is it better low rev or higher rev and this will sacrifice streetability, or better not to kacau anything and leave it stock.even if u put hi cam also u might facing idling problem.
so if ure afraid of all this,dont play engine mods,makeup only drive slowly and dont forget to put larger exhaust so that ppl will scared to kacau you. :)

hehe..yala hor
but dowan touch tat valve train la can mod other ma.like fueling n air intake ma

 

[raja_emeperor]

u can start with open pod air filter, i dont think it is wise enough to put fuel regulator, this will only wasting your petrol, better tune your air fuel ratio.use SAFC as a start.
happy motoring. :)

Bro,

Have you checked out "How Stuff Works" ? There is a specific write up that gives great pictures and stuff.

That said, Laymans terms, adjusting cam timing is equal to adjusting the rate at which you breath in and out.

If your body is at rest, the breathing rate (Cam Timing) will be very much different from when you are running after Ben Johnson in the 100m sprint.

Hence get the two mixed up, like running after Ben Johnson with a breathing rate set to rest.... well... you get the picture now.
