How to now blacktop or silvertop.

IMO If youre driving around town and want to make to engine more responsive or suitable in terms of daily driving then i would do the following below.
Check if piston rings is worn.
Ensure timing belts and seals is in good condition.
change extractor, perdana version mufflers (can be after markets)
intake manifold and air filters
Engine mountings to full bush
Good quality spark plugs
That should be just perfect, reliable, fuel efficiency, high revving response and low budget.

Why not just start with an intake an exhaust if youre really on a budjet? The car will breathe much easier with those 2 basic mods...

Hi, i m new guy here, i have question, if 1.6mivec rojak with 1.8 block,why got knocking sound?

 

[LuKa]

You can't really get buta buta 20HP out of that, you need management and etc to fine tune it as well

this is nice... "Buta-buta".... thats hilarious yar....

Tar
r u a Rookie.. gotta understand that modding NA is Lots of money n little gains..

 

[wira4g92]

hi Luka, I heard NA more easy to maintain,that stopping me to upgrade to turbo

 

[zac]

If you sure that is knocking sound then apparently the problem lies with fuel supply or engine compression setting...

if you are bad luck enough then a NA would cost you bomb too... like me... hoho

 

[LuKa]

maintenance is cheaper since less parts involve... but to increase hp.. a lot you hv to spend for but gains are minimal..

Hi, i m new guy here, i have question, if 1.6mivec rojak with 1.8 block,why got knocking sound?

what piston used in the engine?

Any piggyback for the A/F and ignition tuning?

might be too high compression or lean a/fuel ratio......

for N/A to supercharges...

From NA to supercharger? Stage by stage? ok let's simplify

1st stage
bolt on supercharger, roots type is cheaper & common but less compression, twin screw better compression but more expensive, centrifugal supercharger best max hp but less compression at lower revs. High flow air filter & 4-1 performance exhaust.

2nd stage
ECU, a/f controller, high volume fuel pump, pulley kit to control boost, intercooler.

3rd stage
Forged pistons, con-rod & crankshafts, performance cams, high volume fuel injectors.

For supercharger tuning, the valve timing is very crucial. Since intake pressure is higher than exhaust pressure in a supercharged engine, the boost might escape through exhaust valve if not properly tuned. This problem is usual on supercharged cars but not usual on turbo or na cars, cause turbo cars have high exhaust back pressure to balance the intake pressure while na engine isn't force compressed.
