So,

what if i have change,

-Hotbits 4-2-1 exhaust system with arospeed straight muffler
- KnN Filter


What to use for 60mm throtle body or 54/56mm throtle body for our 4g91 which already mod with extractor and ekzos.... like ijoe say....


mind to advice ?:D

 

[alvin24]

I haven't tried 60mm t/body, so I won't comment on it. I'm currently using 4G93 t/body (54mm.. or was it 56?). Which ever it is u put on, don't forget to send ur intake manifold for porting... else the t/body change won't make any difference at all.

Alvin,

My turbo time showing 999 at the display and not counting when I switch off my engine.Before putting volt stabalizer nothing wrong with my timer.Sikit confuse maaahh....maybe kong already

Yong

that a good idea....mine always kena cucuk...then you know laar...1.3 and 1.5 ori...kena tapau kaw kaw maaahh....I tried to cucuk 1.8...cannot over take..frust woooo....that's why I want to increase my hp....at least can cucuk angin beb....

y ur car cannot cucuk 1.8?when 1.8 car stop somewhere then take ur finger then cucuk la...(just joking)

basic one is change ur plug,i think iridium should be ok.then cable plug,gsr thtl body,clutch plate n flywhheel(lighten one)air filter recommended hks spf or sard(i use that)...just the basic...more xtreme mod later i tell when succeed my xperiment with my engine...

 

[tajulsans]

I think its not really important to upgrade to iridium plugs and low resistance cable.. not that much improvement can be felt..

Breathing stuff and exhaust stuff should be the highest priority, most economical in term of power increase / money spent.. Lighten flywheel also should be considered for the extra "feel".

 

[alvin24]

Speaking if plugs... if anyone wants cheap Denso Iridium plugs... let me know. I got jalan to get it cheap... do check the outside prices before enquiring with me.. then u'll know how to appreciate how LOW my prices are. =)

[alvin24]

I forgot how much I did mine... too long ago to remember... I think it was 60 bucks. I don't think anybody polishes their intake manifold, not as important as to polish the head.

 

[ijoe]

already ask my mech to do port & polish the inatke manifold...he asking for RM100 for port&polish, new gasket(RM20), workmanship & Tuning(pakai telinga)...
mybe next week want to do it...and use back my 60mm TB..
