Hi everyone, just wanting to know if any of you have done any kind of performance or power upgrades to your 4th gen Jimny to help when going up hills and highways? I know that there’s not really too much you can do with a 4 speed in terms of high revving but maybe anything that has helped fuel consumption when revving so high at 100-110kmph. Also, a little worried that constantly having to go over 5000rpm on highways to maintain speed, especially uphill is bad for the engine if anyone can provide their thoughts on this.
Thanks in advance!
I don’t think driving hard should be an issue. Suzuki will have done lots of miles road testing the model before release. And by and large the 4th gen shares much with the 3rd gen. And they have been about since the late 1990’s.
As for mods. It depends really. The engine should respond the same as any other naturally aspirated engine.
Ie
Improved breathing mods should make it run better. Although for the most part you’ll be shifting the power curve to the right. More power rather than more torque.
So a good intake and exhaust would be a start. Maybe even a 4 branch exhaust manifold if such a thing exists. The downside is. Aftermarket exhausts will be noisy and a 4 pot inline motor rarely sounds good. And many aftermarket cone filters will not filter as well as the standard one.
An ECU tube/map should help too. Although gains will be limited. Not sure I believe some of the claimed gains and I’ve not seen any back to back dyno runs. A remap with mods will make the most of the mods. But this would need to be a custom map on a rolling road.
Ultimately you are limited by the fact that it is only a 1.5 litre na petrol. It just lacks displacement for big grunt.
There are some turbo and supercharger kits about. They ain’t cheap but are the only real way to significantly increase power and torque.
Or you could look at an engine swap. But no idea if anyone has done anything like this yet.
Personally my current aim is a supercharger kit. But probably not until it is out of warranty.
