What is the different between 1.8 gearbox and 1.5 gearbox

[wsonny]

All sifu,

Can anyone tell me wat is the different of 1.8cc gearbox wit 1.5cc gearbox. Currently I driving Wira GSR na but wit 1.5cc gearbox. Wat I feel is the fuel consumption abit high compare wit my frens. Does the gearbox effect the FC of the car. Wat can I do beside change gearbox.

Thks

Last time I heard from a friend that lower cc engine gearboxes are geared with higher ratios to suite the lower power. So if you use bigger cc engine with a lower cc gearbox, acceleration will be superior but fc will suffer due to a higher final drive. But I'm not sure for mitsu 4G93 and 4G91. But for 4G92 and 4G13, it is that way. Because I thought of doing this project last time. So did some research.

yup u might be right coz pick up might be very good. when i driving at the speed of 100km my rpm owill b around 3.5k. So do u think i need to change my gearbox back to 1.8

If you do, sell me the 1.5 gb :)

Hmm... That is personal choice. Some people want to gear their car fr acceleration and they do not do much high speed cruising. So they set up like this. Some do more high speed cruising, is fc conscious, and prefer quiter, stress free ride. So they change.

For me, personally, I will change. I hate high fc and a loud cruising. I can give up that little bit of acceleration for better fc and cruising in return. Furthermore, the 1.8 with 1.8 gb isn't underpowered at all. The acceleration is quite good already.

Carlyap and Izso wat gd u guys using now, if 1.8 can we swap

 

[carlyap]

std 1.3 gb cable. what is your condition 1.8 is that 222 gb ?

wsonny... ultra long ratio.. 3 speed... auto. LOL Funny thing is I get super good FC. 15km/L on a good day and 13km/L normally.

No point swapping. But if you're looking to sell it, let me know.
