1.3 and 1.5 gearbox have the same ratios... so the only difference between your gearbox and a 4G91 gearbox is the clutch pump... you use back 1.3 g/box means u're running on cable... don't use racing clutch. If you do, the cable will tend to putus easily... else some other problems might arise in the long run. The cable can't handle the force.
Don't use full synthetic... it'll make the tappet sounds arise faster. Always use thicker oil to reduce tappet noise. I find castrol Magnatec to be quite good ar reducing tappet noise... its semi synthetic.
Don't use shell... its instant engine noise maker. EVeryone i know who has tappet sounds is keeping their distance away from shell.
My Gearbox is F5M222 VRZG.. I'm not sure from which engine it comes from but not from wira 1.3 as wira 1.3 is F5M211.. ratio is very close.. and its running on hydraulic clutch of course.. i'm running it with 8.5" parout clucth which has very good grip.. next change i wanna try the 3 puck ones.. hehe..
ive been using fully syntetic all this while.. my bro who is running with 4g93 recomends me to use fully syn ones.. i also not sure..
on the vtec thing.. its a true story.. but maybe the vtec guy is letting go abit.. who knows leh.. haha..
to all all 4G91 owners...i have been using this engine for about 2 years. not bad engine, smooth, good FC, but of course the tappet sound is quite noisy. but this engine never give any problem. Anyway, this car a bit sluggish from idling to about3-3.5k rpm, after that power only comes...go up hill must put it in high rpm...
of coz an EK will tapau u laa.. can follow initially only mah.. then later he tapau u laa.. well, thats what happen to me..
a lot of thing determine ur car pick up.. gear ratios, power band, rim sizes, weight etc etc.. but true, my car only have good power coming above 3k to redline.. below that its quit sluggish..
alvin kor kor...theg guy told me to send to my car to the workshop this coming tuesday. again posponed from friday now tuesday... but he said his car will be there already CONFIRM. so i just go there on tuesday and leave the car there...and about the runner...can you help me out...??? some more my financial state kinda tight now. :(
can be the vtec got lots of prob edi...my fren kher also tapau b16a wit his galant...4g63 sohc eci multi onli...n his car also got prob edi 1...2.0 man...my 4g91 still can win him...but after he repair everything cun cun edi...hahaha...duno lah...belum cuba belum tau rite...hehhehe:P

the only way to make ur existing gearbox ratio closer is by changing the final drive, or change the 3, 4, 5 gears since 1 and 2 is ussually good enough..
Linear Mode
