YA....revving over the limit will cause your engine valve to get stuck/break & then you will have to open up the engine, change the broken valve/s , retune the topset....etc...which may cost u around 7-800 !!!!!!! so don't take the chances. just upgrade to 4-2-1 extractor & then straight piping (not too big) all the way out with a not too big silencer will make u feel a little more power. change your petrol filters every 10,000 or 20,000 km & use semi-synthetic engine oil (like DUCKHAMS QXR 10/40) then it shd be better....i did this to my previous car....iswara sedan 1.5manual 1993 model & it made the wajas choking behind me !!!!!!!! OH I FORGOT.....change the airfilter to K&N (the metal type...its round in shape & chrome in colour with some wire meshing on the inside).....

u should tekan KAU KAU d minyak....until no space to left...hehe.....sure faster :P

 

[norika_sakai]

ermm...i've try with my iswara....around 14 second ......rev until 6500k rpm....but when you hear the engine sound your heart sakit ler... :D :D :D :D ...

4g91 can plug and play in iswara ar ??? or if use mivec in iswara, mounting have to modd or not ???? or plug and play ???...new to car modd.... :P :P :P :P

 

[huakenny]

should be plug n play i think......REV it for future ma...REV it kau kau.....evo oso kalah to iswara...hehe

 

[zero_kool]

well...depends on where the power kicks in la......i think in a iswara 1.3 orginal 4g13...should be around rpm 5k+- la......

oso, u wanna keep ur ori engine? or wanna transplant....if keep ori engine...then yeah...go for the 4-2-1 lor...and maybe a little tuning...but if wanna change engine...4g91 la...cheap and good. turbo on ori engine? dun need 1/2 years...2-3 months gone! and if u transplant 4g91, yes, u chassy needs to do some knocking and adjustments...the foreman should knw how and where la...if dunno...dun pay him.. :P. maybe some air-filter changing would be oso reasonable la...depends on ur budget..get K&N..love it!

cham2020 car can rev 2 8k rpm is bcoz his car is 4g13 carb...kiran...ur car injection mah...should cut at 6500 rpm edi 1....

my 4g15 wit auto tranny 1st gear 80km/h wit 15" rim...coz they say 13" not accurate wor...

now my 4g91 is 40km every gear..means 1st 40...2nd 80...3rd 120...4th 160....5th 180 fuel cut

 

[quick_shaq]

i guess i'll go for the 4-2-1 thing with a new piping and exhaust system......
what more can i do huh!!!i dun want to change my engine coz i'm still a newbie.....
anyone got any idea ???
to all the sifu out there when arr need to change brake pad ? clutch ?
that day i tried rev 5k it feels much faster then before but when i went home my brake was smoking !!!!! why is this happening takut lar mcm ni.......tu baru 5K not yet 6.5K or 7K like some of u suggest i dunno lar whats gonna happen?? :unsure:

maybe u overbraked......iswara brakes are not very powerful....check yr brake pads & if almost worn out then change it.....as for the clutch...at speed of 100km/h yr RPM shd read 3000........at abt 130 or 135km/h it shd reach 4000RPM....its same for iswara/wira 1.3 & 1.5 manual....so check when u drive......if it shows higher RPM reading then yr clutch is getting worn out.
