Hi all, so a few months ago I joined the Jimny club with a 2011 Jimny Sierra. I started hearing about the M13A to M18A conversion, and before I really read about it in detail a low km's 2006 Liana popped up that I was able to snag for what I thought was a fairly decent price...only to now read on this forum that a 2006 engine won't be allowed to be put into a 2011 vehicle due to emission standards. Is there anyway around this (anyway to reduce the emissions of the 1.8?) or am I SOL and $1900 down the hole?

You will need to discuss this with the approved engineer who you intend to use to certify the car. If it can be proven that there was no change in emission regulations between 2006 and 2011, the swap may be permissible. If that can’t be categorically proven, you would be forced to perform ADR emissions testing which is a $3.5k exercise, regardless of outcome. (As in, if it fails you pay $3.5k per attempt)

TBH the whole emissions thing is wonky. These conversions using the stock computer will no longer comply with m13 emissions because of the increased capacity so the car should be retested in any case to confirm itmeets the ADR.

Good day all, Thanks again for this post, be super usefull to read it. I have bought my m18a, and I am in the process of planning the build.

I have some questions:

1: Has anyone managed to use the m18a flywheel and larger clutch? I checked today and it fits in the gearbox shaft.

I like the idea of a bigger / heavier flywheel for offroading, I am running reduction gears, so just keeping the reves at 3-4k would be ideal. I do also like the idea of a slightly larger clutch, which will assist me when towing a trailer. I see one can buy new clutches for the Suzuki Liana online.

Is there maybe something that I am missing / Overlooking.

2: The size of the second pulley (directly on the crankshaft) seems to be smaller on the m13a. Why is this? and which pulley should one use? Will this not change the speed at which the water pump, & alternator etc run?

3: My m18a seems to have the EGR valve blocked off, Do I need to install the m13a EGR valve? is this optional, better for performance, fuel economy, etc? What would be the consequences of leaving it blanked off?

1. I haven't measured but the jimny bell housing is pretty small.

2. Off the top of my head it's just the outer belt that is sized different meaning the power steering and AC gets driven harder on the 1.3 compared to the 1.8. I'd recommend running the 1.3 balancer/pulley.

3. I believe the Liana didn't have egr from factory. If youre running the stock jimny ECU, then you will need to run the egr to avoid an CEL. Pretty sure this will also be required for engineering. I've run the 1.8 with and without the EGR, I was not able to notice a power or economy difference and there was no noticeable carbon build up in the intake after 75k Kms on the original 1.3.

[zukenutter]

1. Two people (on facebook) have said they've installed a Liana 1.8 flywheel and clutch with success, but I did see a third report of somebody saying it wouldn't fit. I have the flywheel sitting on a shelf ready to give it a try but I've been waiting until the next time the gearbox comes out. The teeth on the flywheels are an exact match.

2. I'm running the Jimny pulley but people have also used the Liana pulley successfully, just needs a different belt.

3. I can't speak about the consequences of leaving it blanked off but mine is installed as factory and hasn't been a problem after five years.

Doing a M15A non vvt conversion on the sons Jimny next weekend, this thread has been really helpful. Just have two questions

1) Can I keep the M15 Bottom Pully, water pump pully and impellar? I am happy to get a custom length belt if thats the reason everyone changes over all the Jimny Pulleys.

2) Car has a 2" lift, will I have to change the oil filter connector? Or will commodore engine mounts give a little more clearance ?

[zukenutter]

1) The crank shaft pulley should be fine and if it's a different size you'll just need to test fit some different 'off the shelf' belts. I'm not familiar with the water pump position on the 1.5 so I can't help with an answer on that. I just swapped the Jimny plumbing over.

2) Commondore mounts will keep the engine in the same position. Clearance seems to be hit and miss in regard to the oil filter connector, I tried mine with the 1.8 oil filter connector but it clashed with the chassis when driving.

thanks zuke nutter

only reason i ask about the water pump is the one in the m13 is suspect....

Hey chaps, I'm halfway into my m18a conversion.

All went swimmingly thanks to all your help. It's great to know what to expect upfront. So far I have the m13a out and moved all its goodies over to the m18a. I have done some measuring and the Suzuki swift sport 1.6 clutch seems to be 95% the same as the liana. Bolts all line-up, clutch plate identical etc. So think I'm gonna give it a try.

I am faced with a dilemma though, from day one I have moaned about Jimny aircon being so weak (In Africa we often offroad in 40-degree weather). The liana aircon compressor is substantially bigger. What're the chances I can install its compressor and the system will work? I assume this is why the m18a has a different diameter pulley, as its harder to turn the bigger compressor.

Do you think I could run this larger compressor?

Looks like it may be a bit too long to not interfere with the oil filter. Apart from that, and the fact that you'll probably need to fabricate suitable brackets it would probably work.

[markmo]

Id suggests talking to an air con guy to see what he thinks. Mechanically it should line up with the bolts and should miss the oil filter but it may make life difficult getting the old one off and a new one on during oil changes.

Edit: Z734 filters are narrower then the Z418's so it may help with fitment.

There is a way to make it fit. I live in Dubai and we have the same issues. There is a local shop that use the 1.8 air con compressor in conversions

Do you maybe have their contact details or more info?


It will mount up perfectly, as it comes from the m18a. Usees same brackets etc just different holes.. I am just really worried that I install it and it causes issues. (I assume the pulleys were also different due to the aircon being different, so might have to back to the m18a pulley?

Here in W.A it's $175 at Packards.

[Gwagensteve]

ADR rolling road sealed room evaporative emissions testing? Wow. That’s very cheap.

Or, Victoria is just expensive.

[Gwagensteve]

Or we're not talking about the same thing. It's clear that a test that's $3500 isn't the same test as one that can be profitably performed for $175.

[zukenutter]

or we are, and Victoria is just more expensive

[Gwagensteve]

Who said that quote was from Victoria?

[sideways]

Who is charging $3500? Packards are engineers, the $175 is for your dyno ADR emissions test for engineering modified engines. It's all on their website. FWIW when I talked to them over a year ago they said they had done a few M15+ swapped Jimnys, I didn't ask what the result was. We just got talking Suzukis.

So where was it from?

[Gwagensteve]

NSW from memory.

[vet 180]

So get it tested in WA and then drive over the NSW. 175-3500 is a huge jump

[Gwagensteve]

So, as I suspected, we’re not taking about the same thing. WA will accept an abridged test. Full adr testing as required by other states is (still) >$3k.

I don’t imagine the abridged test would be acceptable elsewhere in Australia.


https://www.sau.com.au/forums/topic/277 ... s-testing/

[zukenutter]

Well I guess my 1.8 shouldn't cross any borders. As I suspected, the ADR testing at $3k (or is it $3.5k) is fairly pointless.

[Gwagensteve]

This is only relevant if the new engine is older than the existing engine, or the engineer determines that for whatever reason the application is so far outside the factory application that emission control will be compromised the new application, or if there is no emissions data for the proposed engine in Australia.

Experience has shown that engineers will avoid/dissuade the owner from dealing with the problem by refusing to certify cars where the engine is older than the car or for engines with no existing ADR emissions compliance.

It takes a very determined owner to pursue emissions testing.

Is it >$3k or $3.5k? I don’t know- if it makes a difference to you ring around.

Bla bla bla! Less fake news please and maybe we can 'Make AZ great again'.

your story, not mine

[Gwagensteve]

Well that’s my experience having dealt with the scenarios I’ve outlined. You can describe them as fake if you like, it doesn’t change my experience. Your local circumstances may be slightly different in that your registration agency accepts an abridged ADR test but that’s not the case outside of WA, and each conversion needs to go through an engineer or mod plate process anyway which will determine if ADR emissions testing is required.

I assume you’re aware what “>” means and you’re just being facetious.

Being facetious to point out that I'm being facetious... LOL

and yet you still continue to ruin a good thread

You’re the one picking fights.
