Crack on mate, never mind the nay sayers, you'll end up with a car that you want, that does what you want, the way that you want it to.... and you'll have built it. Hats off to you.....

The 1.5td makes 67hp, 97lb/ft. A M16 makes 105hp and 106lb/ft.
I won't knock the fabrication skills and hard work it takes to do this sort of conversion, but a better choice of engine would make the conversion easier and the end result much more rewarding.


Hehe... Thanks for that.

I guess once the diesel pump is wound up it should make a bit more torque and still be significantly better on fuel...

Edit :

Just read the rest! Sounds very much like this is a good engine for the OP and no doubt something he had ideas on anyway.

Keep up the good work!

Personally I like both styles of engine for different reasons. I still giggle at how I used to drive my first sj410 - I think that thing was at red line the whole time off road!! hahaah... Funnily enough used boat loads of fuel for a 1 litre... But then I love diesel torque also - just so steady...

Hey ho...

Hit a bit of a stop on the Jimny over the weekend waiting for bits and bobs to turn up so decided to build a removable ramp for my trailer instead, just needs a bit more paint and some expanded steel mesh.

Just knocked up a quick spreadsheet to make a graphical comparison between old and new powertrains.
I've based it on the following numbers, please feel free to correct any as they have just been quickly sourced from google:

Vauxhall R25 Gearbox Gear ratios
1st 3.95
2nd 2.187
3rd 1.387
4th 1
5th 0.845

Suzuki Jimny Gearbox
1st 4.425
2nd 2.304
3rd 1.674
4th 1.19
5th 1

Transfer box high ratio 1.32

Final drive (2000 manual) 3.909

Rolling radius (205/70-15) 0.32m

The orange lines are gears 1 - 5 with the new setup and the blue lines are gears 1 - 5 on the standard setup. The astute among you will notice that my car doesn't have standard size tyres but i can't remember the size at the moment so i've based it on standard road tyres just to make the comparison.

Does anybody happen to have any rolling road data from a standard G13BB engine'd Jimny?

Err. I'd be quite surprised if an old Isuzu diesel would rev upto 5500 as you're suggesting.

I'm not intending to operate it here but that is real rolling road data so yes it will run there

I've ditched the spring spacers as they were utter rubbish, and I've invested in a set of 4" lift front springs from jimnybits. I've got the standard front springs on the rear for now. I attempted to take the rear bump stops off to space them out and they just tore to pieces so I've somehow gotta get the male threaded part out.

Modified my range lever to cope with the body lift by cutting it about 3/4 of the way through, bending it and then welding up the cut, just needs an extension now to bring it to a decent height.
