Does it matter?

yep, because you use the 1.3 Sump - they are different shape

[Jazzor]

Not if you don't want a dipstick.

If you are changing the sump changing the rocker cover is a fast job while the gasket stuff is drying .

[zukenutter]

I'm not trying to avoid the effort, kinda liked the idea of having it forward in the engine bay.

[zukenutter]

I discovered today that the dowels in the Liana flywheel are spaced too wide for the Jimny pressure plate so I'll be using the Jimny flywheel for now as I can't afford a new clutch atm.

Tried to buy a 5 point torx bit today but lucked out so I'll be drilling the heads off and using a more conventional screw.

Tomorrow is the big day, can't wait for the test drive.

[zukenutter]

Modifying the Liana rocker cover was easy enough. I tapped the forward dipstick hole and screwed in a matching bolt to block the hole.



The new dipstick hole is 8mm and just a matter of carefully drilling straight through, then a countersink bit to bevel the edge of the hole.

[zukenutter]

1.8 is in and running. A few hiccups along the way and I know understand just how much work is involved. Had some trouble mating up with the gearbox. Test ran it at about 5:30 tonight and the power/torque is great.

Ran it for about 15 mins on the test run but idle hasn't settled yet? Also on start up the revs shoot to 4000rpm. Am I just being impatient and need to take it for a longer run? I've checked that the IAC is the 1.3 part.

[zukenutter]

Another day of tidying little bits up and running it, over an hour with no change to the idle. Got back and decided to swap the TB for the 1.3 version so I'd be mobile for the weekend. First start it was sweet and actually had more power than with the 1.8 TB so I'll run it like this until I have more time to have a play.

Has anybody tried swapping the throttle position (name?) sensor?

[nevilleb]

Hi Guys
Just done my M18A conversion- running well - plenty of power and idling as it should! The most difficult part was getting the top starter bolt out of the bell housing (it was seized solid ) I had to cut the head off with a dremel grinder which took a loooooong time.
The rest of the job was straight forward apart from trying to find a rear main seal for the M18 as the M13 seal is different - I was concerned as we don't get the M18A engine in South Africa...... I eventually cross referenced the seal to find that the M15A that we get in the Swift is the same as the M18A......
This has to be the single best upgrade that you can do to the Jimny!

Are you running the 1.8 throttle body Neville?


I know that JayKay and Tim are running the 1.8 TB but mine just didn't seem to want to play and regular driving was also effected, not just idle.

Today I pulled apart the seized 1.3 TB and the 1.8 TB to compare. I'm thinking that I'll make an adapter plate to run the 1.3 idle housing on the 1.8 TB, fingers crossed that it works. If not it'll be an interesting experiment

[zukenutter]

I think I've figured out why my 1.8 wouldn't idle, I'm pretty sure that I'd installed the idle sensor wrongly trapping the spinning tab. Not sure if I've bent it. Does anybody have a photo of the tab on the end of the spinning tab. My Jimny's tab is straight but the Liana tab stick out on an angle.

[tim80z]

I don't have a photo, but I do remember that they both stuck straight out. Hopefully you will be able to bend it back to straight.

- Tim.

[zukenutter]

Thanks Tim.

[zukenutter]

Straightened the tab, put it back together properly, fired her up and was perfect straight away.
There's a notch at the very end of the sensor cylinder that the tab needs to slot into, get it wrong and the tab/spinning shaft will be jammed in. If this happens the sensor will not bed properly to the housing, my mistake was to screw it down thus crushing the tab.

Throttle response is now much improved from idle with the Liana throttle body as the other guys have already discovered. I'll have to start my economy test again.

[Jezza86]

good work, great to see this is becoming a basic mod!

[Nathaninadelaide]

The m16 from the swift sport has around 100kw where the m18 from a liana has around 92 kW would a swift sport engine be an option

[zukenutter]

The difference is the rpm that the peak power is produced, 4x4 is best to have power down low.
1.6 Sport 100 @ 6900
1.8 92 @ 5500
Plus the 1.8 has more torque at slightly lower rpm

The 1.6 would still be better than the 1.3 and probably also better than the 1.5

[Nathaninadelaide]

Thanx I haven't been looking too hard but it's not too easy to find a 1.8 but there are a couple of 1.6 swift engines from japan delivered for around $400
I thought to get one from Japan as most have very low km

[zukenutter]

Any size increase will be a big improvement on the 1.3

[zukenutter]

I'm finding my snorkel is adding restriction to flow due to it's narrow diameter, I know you guys all run the safari type snorkels which have a larger bore I think. Anybody else have a slight delay after idling at a traffic light for a couple of minutes?

Also, does anybody know what the difference is between coil packs Jimny vs Liana? They are a different serial number but look identical.

[Jezza86]

i would have thought a M18 would have run a larger area filter/airbox combination then a 1.3
is the snorkel outlet that much smaller then the 1.3 airbox inlet?

[zukenutter]

It has a tight point/bend where the snorkel comes through the guard, I fixed the rest of it several months ago but nothing can be done with that bend. It was fine with the 1.3 but now you can hear it struggling to suck air through it at full throttle and with a two metre long path of flow doesn't help either. I think I'll graft another inlet to the air box with a cold air intake through the grill that can be closed when off road.

I press the throttle in 1st gear from idle and can have a 2-5 second delay before I get any power

That's exactly what is happening with mine. The extra plumbing has definitely helped with low down acceleration but the delay is still there. My delay is fairly random but always as I try to accelerate from idle. Like you say it can put you into awkward moments in the middle of intersections.

Anybody else encountered this?

[nordom]

yepp, one local guy, converted m13a to m18a with A/T encountered this. I'll get my car with the same setup this week, i guess, so i'll check, if i'll have the same problem. My guess, that this could be cause of bigger displacement and lack of air due to the engine block ventilation via cylinder head. Another guy made an experiment on M13A, disconnecting that hose from air filter box and the problem with "no power for 2 secconds after full throttle from idle" disappeared.

[zukenutter]

^^ the hose from rocker cover to the rubber inlet pipe between the throttle body and airbox?

That hose has your PCV valve in it. Maybe it's worth checking your PCV valve is working properly?

[zukenutter]

Just had a read about PCVs, I'll check it tomorrow. Probably needs replacing so I'll order a new one.

yes, that one. I've the link to that experiment, but it's in Russian unfortunatelly)

here it is http://suzuki-club.ru/threads/62741/ . I'll try to translate it to English if You're interested, but it'll take some time.

Good news is they are cheap, ~$10. Get a new grommet for the rocker cover at the same time so it seals up nicely.

got the rig today late in the night/early in the morning with M18A installed with at. I'm running on M18A throttle body with M18A idle air control valve (didn't have a 5-star screwdriver) and had about 1800-2000 RPM idle at first run, but after about 60 km it has stabilised at about 1100 RPM (it's still higher, than on M13A, but better than 2k). Didn't encounter any idle RPM oscillation, but maybe i need more time to detect it. What i didn't like at all, is that i've encountered something like dead clutch on an auto transmission (or accidentally engaged N for an at): the engine revs, but no responce on the wheels. Strangely, it usually occurs at the start of rapid turn. And yes, I've got the same problem with power gap in case of full throttle after idle.

But I'm still happy. Now it rides like hell.

[zukenutter]

Try gently removing the idle air control sensor and try turning the brass barrel at the end of the shaft, it should turn freely. My bet is that it turns but not freely.
