Engine change??

does any one know if you can change the engine to a holden 186 engine
is the ratio the same and how hard is it to change the mounts??
cheers

Now you're asking! I have no idea. The 186 is a straight 6 right? There was a straight 6 landrover engine that needed different panels due to its length but I don't know if a 186 is longer or not.
Basically you can get anything to fit given enough work. Mounts are easy to move along the chassis if you can weld. The front panel can be moved forward like a defender to give more room.

Scrub all that, look here...

Seems you need a social flywheel as well.

yeah it is the straight 6. i think i've seen someone else that has a holden, not 100% if its a 186 thou
it has a nissan sd23 in it atm, an that is quite under powered and is smoking real bad. so was thinking it would probably be cheaper to change it
i have done some welding but i aint no pro, but i do know a few people that could do it for me!
not sure if its better to change or not...dont know if it would be better to have diesel and less power or petrol and more power??
here is the 186 im looking at..??

hello landybuff, ah now your im my sort of territory what do you want to know about holden motors mate.
they are almost a straight fit but depends what you want to fit it into,
if you mount it into a series landrover you will need a bell housing adaptor, you may need to trim some of the bulkhead around the bell housing area and may need engine mounting adaptor, if you could get hold of a holden powered landy then you'll be laughing,

tell ya what i'll do i'll look into it and i'll give you some info and or links to help you out.

hey spring don, yeah they are a straight six, 186 cubic inch around 2.9 to 3.0 litre very good to get parts for, actually i have a carby from a holden on my landrover, the best upgrade i have ever done she had a big improvement in pick up from the standard solex carb.


i did a google search and found this, v8 powered series one restored.

I'd say more power is better! But it does depend what you're using it for - diesel is more economical.
That said too much power through a series transmission can snap half shafts.
If I were you, I'd look into how much the ancillaries, special flywheel and any adapters cost before getting the motor.

Edit - ^ what mr.kommer said - he comes from where they grow holdens.

it has a nissan in it eh, ok so the other owner had modified it, it maybe almost a straight fit

have a look on this forum you can view it for free, but will need to register to ask them questions, now its free to register but you will have limited actions.

here is another link,
http://www.aulro.com/afvb/holden-powered-series-land-rovers/137920-186-conversion-kit.html

but as you said it has a nissan so im thinking the only thing you may need to do is change the engine mounts and maybe sort out the bell housing clutch area, but i think its best to ask the guys on aulro as they have many owners with holden engines fitted, i have been offered a landrover with the red motor fitted for $600 but i turned it down as i already have a landrover. im told the holden conversion is good, but torque is another concern, but if you treat it easy you should have no problems as i have known a couple of blokes that had them and they say its good.

Actually, I've just remembered that I read somewhere that most people in Australia think that Holdens are a bit rubbish and you'd be much better off getting a ford.
Just saying what I read.

thats quite a lot to take in.
cheers for all the info tony, yeah Australia is a good place..you from brizzy..thats a top joint!!
anyway...i wanted a engine with heaps of power....love that v8!
i kinda want a diesel as it dont like paying for fuel...even thou im not paying for it!!
and wat spring don said bout snapping shafts.....i read somwhere that if you put somthing with more than 140hp an 160lbft torque you have to change the gearbox etc!!
i had a look at tht aulro website and had a look a few forums! there is quite a bit to change other than wat u mentioned
and i would use it more for off raoding....so would it better if i had a diesel engine for torque??? would i be better to put a bigger nissan engine in it??
my mate has a nissan ed 33 in his 109 an it has plent of power but it very heavy....any thought on a td 27 or 28??
wat u say spring don bout holdens is true...they made good engines...kinda...but ford made many many great cars compared to all the memorable holdens......??

What exactly is an engine ratio???

not exactly sure sorry..
how would i find that out?

i dont totally understand how an engine conversion works but was landybuff talking about the engine compression ratio? i know someone who has put a ED33 (nissan 4 pot) into a landrover series, and they didnt get something right...(i think it was adapter plate for gear box, but correct me if this doesnt add up)....so in first gear, low range, it would idle up his very steep driveway, which i would have thought was due to the 3.3 four pot having far more engine compression than the previous engine!! but any knowledge/corrections that can be passed down on the subject would be great!!

i think you would be better off with a 200tdi or maybe a isuzu 4BD1 that was fitted to the land rover 110 county in australia in the 80's, see in the 80's when landrover went over from the series 3, they called them county's and the landrover engine, the 2.5td and petrol was not up to ausssie standards apparantly, so they had them bought over as a CKD kit minus the engine and fitted a small iszu 4BD1 truck engine, 3.9l non turbo, massive torque, and they also offered a 3.5 rover V8 as well, at the time aussies wanted a big engine and the 6 cyl landcurisers were selling like hotcakes, and basically landrover's popularity was dying real quick, so that was theri answer, even the austarlian army used the isuzu 4BD1 engine, they told me once they never used turbos on them as they would make them unreliable as australia is a large place they didnt want to be broken down 100's of k's away from a base.
isuzu 4BD1 non turbo.

personally i have heard bad things about holden engines in landrovers, some wish they never did the engine swap and also one bloke i know called tony as well said he heard that they have been known to overheat in a landrover as landrovers will spend a lot of time going slow and the radiator was not up to the task. i would personally would not use a holden engine, if i were you id probably put another 4cyl nissan in it as it would be a easy swap as you have one in it now.

just more power, if you put a more powerful engine in it will idle up an hill

ratio? in what way

yep your right i think landybuff means comp ratio.

i wonder if he talking about gear ratios being affected with the use of a non landrover engine, say gear box ratios or diff ratios.

is it though? - i have got that same engine in mine, ED33 is an old bus engine (nissan civilian), but it doesnt idle anywhere, sure its got loads of power...and just thinking a bit more about it, the ratio 3:54 comes to mind, where is this from?cause im pretty sure that this is what i have, hence it doesnt idle up steep driveways, but this other guy had the wrong ratio - it needed to be 3:54 (might be 3:5:4??)

3.54:1 diff ratio is from the early range rover, standard land rover series 2,2a and 3 models had a 4.75:1 ratio.
3.54 diffs wont help with crawling slow off road whereas they are better suited to highway use instead of using a overdrive.
i have 4.75:1 diffs in mine and the standard 2286 petrol engine, she goes slow but is good off-road, but 3.54:1 is still okay as long as you dont do a lot of slow moving i.e crawling if so a underdrive could be used it'll lower the gearing even more.
