Jimny to many RPM on highway - Higher gear ratio

That speed with your RPM will actually do the engine good, apart from the fuel consumption, very little load at that speed but with a lot of momentum


Steve.

Why don't you want to fit bigger tyres? You wouldn't have to go for the 31" Just say 215x15. Will give you a slightly better MPG I would have thought, but not look to bad on the vehicle.

The Jimny G13BB motor is designed to run all day at 4000 revs/100 kph. That is its heritage from a M/bike manufacturer. Without those revs you would not be able to overtake or zoom over hills.

My Jimny sits on 120kph in the Territory for months at a time, one would never get anywhere otherwise. When I go to Adelaide every month (800kms each way), the Jimny sits on 110kph towing a teardrop caravan. Without those revs I couldn't do it. Would have to pull over to let a line of cars go past me.

Accept what you have, ignore the revs or put a picture over the tacho so you can't see the revs

Keep the oil up to the car, change every 5000 kms. Put decent platinum spark plugs in and change the air filter/oil filter when you change the oil and you will have no problems.

I've been driving mine for 11 years with no hassles and only 2 parts broken down in all those years.

What he said!

By the time you've paid for an electrically operated transfer box and worked out a way to make it work in a car it wasn't intended to go in, you could have bought a car that had one from the factory! It would likely have Variable timing also, which may save on some fuel.

The first motorway journey I had a Jimny was in an early single cam hard top model and my thoughts were not too diferent to yours, but these cars were not designed to sit at speed for long but the engines are designed to be able to rev like that.

Bigger tyres will not aid fuel consumption anyway as it will take more effort and thus fuel to get up to speed and you will miss the acceleration you have now - not that it is that impressive in the first case.

So I would just accept what you have and make the most of it.

Also, you do need those revs to keep it in the powerband up hills on motorways!

A VVT electronic transfer woud totally stuff your gear ratios. Starting in first gear would be like start in second gear now. It would be undriveable. ZookFastback is 100% correct about the Suzuki motor loving big RPM. When I had my last Jimny with 24% reduction trial Jimny gears and 235/75R15 tyres it would sit at 4950RPM when doing 100km/h and sometimes for hours at a time. 110km/h was very loud

I ended up installing sound proofing throughout the floor and side panels which helped a lot.

Your age is really showing Paul :laugh:

But as other have said, they need to rev. Once i re-gear, i will be sitting on around 4200rpm and that's with 31's...
