why i must change gearbox..??
give me a good reason
i need to know..

 

[Dampachi]

4g91 Gearbox
Clucth Pump

1st of all yur 4G91 gearbox got low final drive ratio...thats why u have no pick-up

u should change to more higher FD ratio, at least 4G93/92 gearbox
or if u have enough budget, try to get 4G92 mivec gearbox

 

[mr_lageenda]

ooooo....
somebody said to me..
now i use 4g92
but use 4g91 gearbox...
that one said,i have a good pickup
bcoz big ratio
but lost top speed..

that true..??

so i must change gearbox 1st
if i need more pickup....

 

[SkYwAlKeR]

[mr_lageenda]

Extractor Zenden 4-2-1
Header 1.8"
After Nenas 1.6"
Standart bullet
Piping i not sure..

adj campulley maybe...hehe~dun noe actually...

maybe you should also consider getting a piggyback and get your car tuned..

get a adjustable cam pulley and set your cams...if you set for more pickup you'll have to remember that you'll lose some top end too.

and why not also go for a lighten flywheel and get a lighten crank pulley? that will help you car in the accelaration department too.

And like the sifu's also mentioned, your gearbox could be the cause of your worries too.

Now for this time i want let u know
already install adjstble cam pulley (aerospeed)

Hopefully u all can try give some idea to solve

So the prob is..??
Mybe injector size to small (210)
Must use fuel regulator

Distributor cannot supply more power (wira 1.6 but skim the head)
Plug spoil (use putra plug NGK 4pcs RM45)
OEM ECU+wiring cannot support my new head 4g93

i think jz bcoz the mapping. coz u stil use back ur sohc ecu. if u gt feel more pedal den torque loss is mean lean burn. u nd to install fuel regulator den use safc tunning back. i oso tune emanage for myself.if wan high ratio final gear, jz take gsr 4wd. den lock. gt mivec use tis g/b, very fast to upshift, like rally car
