Ola`s jimny project

Found a M18a throttlebody (54mm vs stock 46mm) and intake for sale in Australia, which i`ve now bought! Hopefully that will cover some of my power cravings..

Struggling with the exhaust though.
I would like to upgrade it, with 4-2-1 and full 2", but getting it custom built where i live is very very expensive.
Found a well proven system in south afrca , "De Graaf", but that also got very expensive due to export costs.. So no go..
The header i find on ebay in Australia, isnt made to make any power they say.. Its basicly only made to replace a stock one, no thoughts given for performance. Then i just as well can keep the stock one.
HM4x4 in italy has got a interesting one header/exhaust, but 1500 eur + tax/shipping is totally a no go.

I`d hate to go dyno tune the car on stock exhaust, and then find a nice ok priced system for sale a week afterwards..
But there seems to be very few making good systems for the jimny.. I even asked KAP, but they told me they have stopped selling theire system.

Random picture of my jimny parked by a jeep.. it seems like some of the Jeeps arent so big either

Got more parts from Jimnybits, installed some of them..
Got 4x HD axles (still wating for 26 spline front locker to arrive), rock sliders, snorkel , and some under protection.. Under protection will be installed when im doing my transfer gearing (high on priority list now), HD axles when i have time for the lockers (not in a while yet).

Also still waiting for the M18 intake/TB... Sea shipping from AUS...

Some pics of how it looks now! Pretty much done outside.. Only waiting for a shiny fairlead for the winch!
Will do some changes to the spare wheel as well, either a 235 wheel or a custom holder for something, not sure yet

Pulled the transfer box out yesterday, for installing Trailgear 87% / 17% reduction gears in the stock push button box..
www.trail-gear.com/product/5323/jimny-electric-t-case-gears 3.74 low, 1.17 high..
Finished today, approx 10h of work in total including topping up oil, test drive and quick tidy in the garage!
Very easy to pull/install the box, but there is some hours in swapping bearings, gears, lining up gears, troubling wth the clutch spring/balls etc..
I also installed breather kit to the transferbox while it was out, as it had to be drilled and tapped.

But all in all, not a bad job at all.. Great instructions, but i also had good help in thread on auszookers about it , + good tips from Yakuza which is also in the middle of the same job on his jimny!

The gearing is perfect for me on 235/75-15`s on VVT gear/diffs (manual)... Very low 1st low, and approx 3400-3500rpm in 100km/h speedo (95km/h GPS) in 5th high.
A bit of gear whine noise, but hopefully it will be reduced alittle when i get some miles on it.

Dont have any real good pictures though, i always get to eager working, and forget to take pics other then to remember where things go etc








Ohh and this one, a good tip for those who are about to do this job; install the clutch springs/balls down in a plastic bag, so you dont have to search for the small parts that can fly all over the place while putting them together!

I'm doing this conversion at the moment and am having some trouble seating the counter gear. You have a link to the auszookers thread by any chance?

Sure do

I had no issue seating the countershaft , other than that it took 2 attempts before it fit without dropping the clutch/ball assembly.
I did struggle alittle with fitting the input shaft + chain drive though. It has to line up perfectly, and then some..
