Is it possible to fit the earlier model 5-speed gearbox in a 2006 Maruti 800?
If so where do I source the gearbox from?
What is the swap likely to cost?

[humyum]

Yeah its possible.U can get one from the gurjaris.Its a direct fit

Good you started this thread,

Any body to enlighten me wheather the 5 speed is a closed ratio compared to the normal 4 speed.

Just curiously waiting like a cat. and they say Curiosity killed the cat.

Fitting the 5 speed gear box would not be a problem at all. You can look at a brand new gearbox which should set you back by 30k but atleast that would be a brand new one. Also you can try the maruti service stations for fitting, I think they would help you with spare parts too

Are you sure it is a direct fit. After going through few M-800 modification threads here, I heard many people saying that 5-speed gear box is a direct fit, so I checked with the MASC regarding the possibility of fitting 5 speed gear box for my 4 speed M-800, the mechanic said that it is difficult & the mounting arrangements are different as well.

I was not ready to take much into what he said, but since I don't know much about the topic, left it & did not probe more.

The info i got from my service person was that it is not possible to fit the 5-speed gearbox in the m-800.Even i feel the same as the mountings are different.

The 5-speed gearbox is the same as the Alto's and the clutch assembly is different. That's what my Service Advisor told me when when i had queried sometime back. But in any case, it would be a misfit is my thought. The 4-speed engine is not torquey enough to match the gear ratios of the 5-speed counterpart.

Wrong conception my friends.

The 5 speed gear box can easily fit the 4 speed M-800 and vice versa.

When my M-800 4 speed gear box was opened for overhaul, i ran on 5 speed gearbox for 2 days.

It felt better hence i've queried for the gear ratio's .

Logically, more torque is required only when the number of gears are lowered from 5 to 4.

Thanks for the enlightenment . Awaiting to hear more in future from those who would be going in for this gearbox.

yeah but the gearbox of the 5 speed is intended for a 47 bhp motor and the torque and bhp graphs of this 47 motor would have been taken into consideration before selectin the gear ratios and not of the 37bhp carburated/mpfi motor.
Anyway the 5 speeder fits perfectly well in place of the 4 speed gearbox but the performance of the car with the swap is something that has to be run on the highway as well the city with and without the AC to be perfectly sure of how good it feels

And pavan bhai how was the acceleration?did u use it in the city and the highway with the ac in the on and off conditon.Do give a detailed report of how u felt.

i had done this swap on my 1990 m800 my years ago the m1000 gear box can be fitted to m800 with some modification

will get in touch with my mechanic who did and will ask for details

the car ran beautifully

[JayD]

Since Pavan has already done it, It certainly is possible. Many mechs say some things are impossible just coz they are lazy.

[mycarhasablower]

as pavan said, the 5 speed gearbox fits just fine in the 4 speed 800, therefore we know it does. Now if you go to the scrap dealer and ask him for the 800's 5 speed gear box, he demands absurd money since the car is rare. I have noticed that the alto and the 5s 800's gearbox seem to be identical therefore i was condiering getting one from the alto and getting the 5s 800s mounts to install it. what say guys?

noidaboy on the forum fitted his M800 with a F10A Engine and ran the stock 4-Speed Gearbox for sometime after which he upgraded to a 5-Speed. The swap is very much possible.
