petrol filter clogged?

 

[DanzEterna]

u check your spark plugs & plug cables.
2nd, check petrol filter, must as well change it
3rd if petrol pump, only at high boost will feel jerking.

have anybody hav idea regarding high cam?? wat effect will it bring to a N/A engine?? can increase a lot of power and make it a monster? plan to put in jun 3 high cam soon.. tq

 

[xtremeleo]

changing it to stock mivec, and getting a cam set for street daily use? err, kidding ke ni?

get a 93 non-mivec head + tomei 316deg cams, fuhh!!!!

a 4g93 satria GTi made a whopping 202hp on the dyno dynamics wit a 308deg cams je, of course it was tuned to perfection by the maestro of microtech himself. mivec head are a fuss imo, plus u'll get ur budget for both head+cams once u sell it, lol. its fecking expensive woorrr

 

[peterj]

hurm... i using mivec + gsr block now... gonna get jun 3 high cam since it has stock idle characteristic and also a afc neo to adjust it...can it be??

 

[xtremeleo]

i prefer a combo of AT LEAST 93 head + agressive cams, and emanage. i suggest getting a microtech LT10s if u can stretch ur budget

just imagine if dat 93 block was fitted wit at least a 92 pistons, fuh!!! higher compression, more powwaahhh!!!!

*wipe drool*

 

[peterj]

hurm.. i repeat here, i now will use back 93 block with 92 mivec head and also it's high compression piston

founded problem .... it is all cause by spark plug... denso iridium new spark plug is useless then an old ngk iridium.. since the seller said that those plugs are for turbo car coz turbo always hot and those plug which concentrate power and produce small spark for cooler ignition..... the problem start here cos my car is running richer then stock turbo car since my car not ori turbo and running higher boost...... the fuel not burn completely therefore cause small explosion like when rev high...... after changed, no problem tq all
