Jimny to many RPM on highway - Higher gear ratio

Hi Jimny people,

Great forum .. Last wk I have bought a Jimny from 03´. I really like my new car but Im not too happy with the RPM it runs when im driving on highway, it cant be any good for such a small engine to run 4000 RPM for 1 hrs when going 100 km/h.

I know the car isnt build for highway use but I was thinking if there is a way to lower the RPM, maybe to change the geatset in the transfer case ??(dont want bigger tires) I have seen many sets avaible on the internet but only for lowering the ratio when putting on bigger tires havent seen any to get a higher ratio.

Hope that someone can help

you can put bigger tyres on and not change the gears, but it will drive like a gutless pig.

you could always try driving slower?

4k rpm is fine, but it will drink fuel.


i think someone mentioned auto diffs had a higher ratio?

Hi,

I dont want to change tires and dont want to go slower yes when im going 4000 RPM it drinks some fuel, thats also one of the reasons that I want a higher ratio.

Im not sure if it is easy to find anyway diffs from a automatic jimny here,.. it is already quite rare

i think you'll be hard pushed to find higher gears, you could always get some made. but i expect that would be expensive.

why did u buy the jimny?

Hm im not sure if I would get them made that would be $$$$

I like it for a long time and got a great opportunity to get one cheap.

I wanted to use it for mixed driving, .. weeksend for offroad(not hard) and during the wk to work which is around 80 km.

i think your going to have to compromise and either drive slower, or pay for lots of fuel. or get a different car to drive to work or quit work and live in your jimny as an explorer?

If you use a high gear ratio during a light off-road week-end, your jimny will become a gutless Pig ...
My jimny is a stock model and my drive is not slower ... the jimny is not a racing car but it is a muddy car ... You can make off-road, snow driving without modifications

A idee , change the engine (put a v8) and all parts of the transmission and you can practice high speed in all ground

Hm, I like my Jimny and dont want to buy another car, .. also I dont think its a good idea to quit my job haha.

I just wanted to make a 50/50%,... Im not racing but just want to go 100 km/h without it sounds like im going 150

Hm, better to try to fit my X5 transfer box on it

There is a way you can have higher gearing in your car without too many problems and that is to fit a transfer box from a VVT manual car (post 2005). They are push button so you would need to figure a way of switching it but I wouldn't have thought it was too much of a problem. The downside is that your low ratio will be also be higher. Don't put auto diffs in they will lower your gearing.

Have a look at this and you will see what I mean

Just a thought!

Hi,

Yes I was also thinking about that option, these cases is also hard to find/expensive here

I would be more happy if anyone had made a geatset with high ratio like the lower ratio gearsets you can get.

I know the low gears is also going to be higher but thats not a problem since im not using my Jimny for hard offroad, only soft
