Fitting a Turbo or Supercharger to Gen4

Since the new 5 door is getting a 1.4l turbo, it may be easier to do an engine swap or see what's done with the equipment when it's released.

I assume the Jimny will need to be in 4wd mode to put down that kind of power safely?

Not sure it would. Plenty of RWD cars about.

My 4.0 litre 190hp Jeep XJ could be RWD and was fine for the most part. Modern Wranglers are also RWD for road use in some guises and they have more power than a modded Jimny.

Hi
ok so yyou can get a Greddy Turbo kit or Rotrex supercharger for your Jimny, yeah I really like the idea and have spoken to several performance specialists, who all tell me they couldnt fit either as they wouldnt be able to remap the Ecu .Can anyone give me any advice, I have uprated my exhaust and air intake but the Jimny is still very flat at the top end . Seems very difficult to get any kind of power upgtage in the UK other than a remap which will give you 10bhp and 11nm for around 300 quid , I dont think it would be noticible.

The stock engine shouldn't be flat at the top end. It is quite a revvy little sucker. Not sure where Peak power occurs, but it doesn't nose over at all, which is really odd and rare in 2020/2021. Ultimately it isn't hugely powerful, although its power to weight ratio isn't actually that bad overall.

As for forced induction. If people are offering these as kits, they must have a way of controlling the fuelling?? Do you have any links to the kits you've seen?

Also if other companies are claiming to be able to 'remap', what are they doing that can't be done with FI?

As for doing this to a Jimny...... I'm a bit torn. I love modding vehicle (some of mine are very heavily modded). But I'd guess a forced induction kit on a Jimny is likely to set you back £5000+ and at the end of the day, even at 100bhp/litre, you'll only be looking at 150hp, although probably a good hike in mid rpm torque.

I'm not saying the Jimny couldn't handle this power. But it is a lot of money to spend for the return.

If you want a more speedy 4x4, the Jeep Wrangler can be had with more powerful engines (3.6 V6 with 286hp, 2.2 turbo petrol, 2.2 turbo diesel) and takes a remap well.

Also the Wrangler is quite heavy so has plenty of weight over the rear wheels. The Jimny only weighs as much as a packet of crisps.

Best of luck controlling 150bhp through the back wheels on a Jimny in the rain.

Of course if you could some sort of centre differential that would make all the difference, but it would be a very difficult and expensive task.

Better to sell it for the mad money these are currently making, and buy a Wrangler SWB.
The 2.0 petrol version delivers 268bhp and the diesel is 200bhp
 

Thankyou for your advice, Bullet cars of australia supply the superchatger and Greddy do a turbo kit (trustpower.com) I guess i am trying to relive my days of a 400bhp series lightweight , just love that awesome power. I thought power pimping the Jimny would be easy . I love its off road capability and the fact its so small.
Kind regards Cameron
