eg9..wat good if psg trd metal gasket to my svt..by not doing pot polish..somebody said..if put metal gasket 1 sot go to pot polish..wat advantage by istall aluminium carnk pulley sell by the performance shop..
Metal head gasket? You'll get higher compression but anyway ur cam degree will not be accurate anymore due to different gasket thickness. Power will not optimize if cam degree is not optimum.
Actually it's not easy to increase N/A engine power. After metal head gasket installation, you'll not satisfied with the power coz the cam degree is not optimum, then you go and get adjustable cam pulley, after that look for tuner to set you cam at optimum degree by using cam dial gauge. From the initial step untill the last step..how much have you spend?
Metal head gasket: RM320
adjustable cam pulley for exhaust cam: RM650 (Toda) -New (Local manufacture unit: RM300-350)
Installation fees plus setting: RM200 -RM300 (Depend on the tuner)
But how many HP do you gain? 1 or 2? But definately got increase in engine respond.
Port polish? of coz good if do it properly.
Actually there is no short cut in engine modding.
The fundamental on engine modding it to increase power output of the engine.
1. Get higher engine compression
2. Get optimum mixture of A/F ratio
3. Aggresive ignition timing
4. Lighter and balance engine internal
BUT it's not easy to achieve the above mentioned element. All also need ALOT of MONEY!!
Why Vtec engine is powerful?
Because the engine meet above mentioned requirement.
Alluminuim crank pulley: lighter unit and increase engine respond BUT I'll not install it because it's not durable. AFter sometime it will start to wear off and become very sharp edge and cut off you belt. Not much you can gain from there. HP won't increase.
Better spend the money on after market flywheel. Although the HP won't increase but power respond do increase and u can feel it immediately.
