I would really like to put a M18a into my 2010 jimny, but due to the euro4/ euro 3 compliance issues, this will be technically illegal or some crap.
but, so is over 100mm lift, without a mod plate.

so i was thinking, would it be worth trying to get all the mods, (tyres, bodylift, springs, radius arms, no rear seats) and a M18a conversion approved by getting the vehicle mod plate approved and do a break upgrade to keep them happy? would this be a viable path to get a m18 into my Jimny? i really would prefer a m18 over a 15 or 16, as i have to cover long distances to get anywhere, and i would like to tow a trailer. i rarely use the high rev range the m13 motors provide and the m18 would be a great balance of torque and lower highway RPM. sure i could just put even shorter gearing in the 1.3 and be able to sit in 5th longer but over 80 kph it seams impractical for me. 4k rpm for 10 hours plus to Katherine has to be detrimental to engine life expectancy and ill probably be able to hit redline before the speed limit in the NT.

if 'the man' says no to a m18, i can either go m15 (which wont tip the 20% increase in power or torque thereby wont need a mod plate <i think>)
or get a m18, and do the dodgey and restamp the block... because its a show 4x4, and i want to keep it authentic... (see http://www.bigblockbruce.com/engine_num ... mping.html for that logic, not that their discussing jimnys)

Any other ideas? i know a 15 would be easier, and cheaper and there is plenty of them about, but the 18 seams so much more practical on paper.

No such thing as a mod plate in the nt. Only lifts over 4 inch need approval which is the same process as all other mods.

Go the the MVR website and download the TAC application forms. Fill it in and send it off and then they will tell you what is needed or will just approve what ya want to do.

thanks Shep!need a prokect for when i finish this heavy ass trailer

ive always wondered,
is the extra 500ml capacity going to make that much difference??

[tslight]

Defibitly get a m18a i just put one in easy change and wat a difference any questions let me know

It makes a hooooge difference...it's the engine the jimny should of come with IMO

Is he SERIOUS?

[atari4x4]

the answer to that question would be farking

M13a 62.5 kW (83.8 hp) @6,000 rpm, 110 N·m (81 lb·ft) @4,100 rpm

M18a 92 kW (123 hp) @5,500 rpm, 170 N·m (130 lb·ft) @4,200 rpm.

30 more powahz & 60 more torx is massive in such a light car.

49 more powahz according to those figures, which gives a fairly impressive 68% more power (and 65% more torque too).

but using the jimny throttle body will kill some of the poneys.

the kw figure is only 29.5kw different, unless i can't count.

[Rhinoman]

Lol, my 'auto filter' had blanked out the French numbers Its an interesting set of numbers though, nearly 70% improvement for a less than 40% increase in displacement, although the higher RPM for maximum torque does point to a hgher tuned motor. I don't know if we got the 1.8, we did get the 1.6 though, I'll have to check the numbers for that one.

[atari4x4]

those smelly surrender monkeys

i stole those figures off wiki, pretty sure they had the m16 listed as well.

TAC = Technical Advisory Committee

These are the people you need to speak to with your intended mods. If they are worries about increased engine size then you can counteract it with bigger / better brakes.

Fill out the forms and see what they come back with. NT is generally easy to get stuff passed. When you do get an approval to modify and carry out the work, you should keep the certificate in the vehicle just in case the coppers want to question the mods at all.

I had a HJ Holden with some big mods done and was no problems when I produced the certificate. I had wider wheel track and also a wildly bigger motor over stock options. Yeah it was an older car but same deal.

Have you got any of this done yet Jezza?

[Jezza86]

none of the approval, but she is 5 inches higher (2"BL, 3" spring) on 30's, with a steering spacer in the shaft and prop spacer in the front drive shaft.
to up the rears ill have to get the jml full float. still got the form half filled out. would like to get a m18, but im concerned about the under fueling issues and reliability, so more tempted to drop back to a m15.
still doing research, and coinciding spending the money to get a custom computer on a m18 to control it with its own throttle and injectors.

[Rhinoman]

Why can't you use the M18 ECU? whats the difference in pinout? surely it would be easier to get one of those to fit rather than spending loads on an aftermarket computer and having to get that to fit.

[atari4x4]

^^^ that's what i'd do.

silo did the pinout change viewtopic.php?t=9779

o'malley bought it & had a few teething issues, but i believe it was a installation error by the sounds of it viewtopic.php?f=4&t=26727&start=60

[Jezza86]

this is awesome news. now to see if i can get a M18 which is euro3 apperoved to be installed into a car that is theoretically euro4.
so far im planing to do 2 applications
one for the body lift, spring lift and tyres to get the height/ width of the car approved.
the other for the above, and full float and break upgrades on the rear, and euro3 complient m18a.

that way i have paperwork for what i already have, and can take my time sourcing the engine and breaks to fit the full float kit

[jimny_timmy]

M18 with m13 injectors solved the fuelling issues according to that money bags bloke that built a fully sik jimny in about 2 weeks and then sold it........

[atari4x4]

same deal with the H27a into a H20a Vitara, overfuels with the H27a injectors but fine with the H20a injectors.

How do they determine that? Its primarily the EFI that makes it Euro 4. I guess that it just comes down to ticking a box on a form.

[atari4x4]

i think it goes on age of the engine, as in you can't fit an older engine to a new car with out having to get the emissions tested etc, can put a new motor in an old car but you need to be running all the anti pollution gear from the car that the motor came from.

[Jezza86]

as i understand it its more difficult to get approval to put a older mother in as a replacement for a newer motor.
as the the m18 will be more than a 20% increase in power, it needs to be approved, and up here your engine number gets checked every couple of years and if it dosent match the MVR is notified.
but if they say its ok to put in a m18, then its ok, and thats that... out of the woods. i can do everything i want, untill i want a drive train made of magic that wont blow up under full m18 load

<edit> what atari said

[Sixes350]

Emmisions is what the standard goes on
