Landcruiser options - please help (V8 to replace 2H in 75 series)

[Banshee]

I am looking to put a v8 in my 89 hj75 series ute as the 4.0L diesel has died :(

What motor should I use? what problems will I have strength wise? I dont want to use an efi motor as I wanna stay away from computers...

I am gonna do air lockers front and rear, and wanna know if my tailshaft, gearbox, axles etc will handle the power - I know that diesels have heaps of torque so a lot of this shouldnt be a hassle but I am not fully sure.

Also does anyone have recomendations of who I should get to do the conversion?? Where I can get a V8 from?? or approx price something like this would cost...

Orrrr for anyone who has done this some advice for me.....

Check out marks 4wd adapters website. They make kits to suit chev, holden v8s from 5.0l (304 cu inches) up to 7.4 l (454 cu inches) using the standard gear box transfer and diffs. Unless your intending to chuck in a 1000 hp powerplant between the chassis rails the toyota drivetrain is more than adequate.

If you want something carbied, I've heard the holden 308 (5.0l), 350 chev and ford clevland 351 (5.8l) have plenty of low end torque and as an added bonus these engines have a large plethora of aftermarket performance parts to improve them if you feel the urge:thumb: .

Happy modifying!!

[marki]

..or a hemi 265 - a better motor for a 4WD in my opinion then any of the old V8s. I don't have any power data available, but I reckon that they probably have a flatter torque curve - my old Val used to pull better than my 308 Berlina. As well as that, of course, being a six they are lighter. And ARB make conversion kits for them....

[Punk_Cruiser]

emissions may be an issue though

[sco_aus]

351 clevo, full of torque. A mate has a 4wd F150? and this thing accelerated up a steep arse hill at 80kph with a car trailer and car on it plus the 2500kgs of the truck itself, was mega impressed. Hell i nearly through one in my troopy, but wanted to stick to diesel.

[MOPAR or NO CAR]

256 HEMI all the way!!!!! Excellent motor - they were originally designed and used in chrysler's range of trucks in the US before further developement for use in AUS (4.3L Petrol if you don't know the engine). Much better than a holden V8 (253-308) any day.

You can go the whole way and get triple webers and matching "6pak" decals too

[roscoFJ73]

A 12 HT would fit in nicely. The cost overall would be cheaper than a V8 conversion.

I know there are some good V8 conversions out there but most of them are less than satisfactory and end up being sold soon after.
Getting the cooling and electrical systems to be as reliable as a factory set up tests a lot of owners patience.

I'm with Rosco. A 12HT or a reco 2H with a turbo. Heaps easier swap and planty of power.

[Bazza_rips]

If you want to go a v8 i'd be looking at a LS1 chev,

but there is merit to the getting the 2H recoed and turboed. the most of which is that you won't have to get it engineered.

Thanks for all the help guys!!! I am going to start taking my motor apart and see how much damage there is and how much it will cost to fix, if its not too $$ then I will do it otherwise I will start looking more into the motors recomended above. The Chev motor looks the go!! Once again cheers for all the help!!:)

Old guy I know bought a new motor for his 47. When the old 2H came out, it turned out that it was only some minor work on the head. May as well have a look before you buy a new motor, you're not going to make it any worse, are you?

[Andy_b]

I would go for a rebuild or a 12HT first. Then I would look at getting a Lexus V8 1uz.

those lexus v8s are ok, but in a heavy vehicle they tend to struggle.

Great in highluxes

[6.5Cruzer]

Don't put a 6.2 or 6.5 chev diesel in it. I have been bashing my head against a brick wall tryiung to get a number of 6.5's to work correctly in my HJ75. They Get hot uses nearly as much oil as diesel which is alot. They are a horrible rattly sounding 60's technology boat anchor. Thats just my opinion though. I would be going with a LS1 and just gearing the ute up a bit to try and drop the revs on the open road. I don't think if you got it set up right it would be bad combination. I would like to say put a ford in it but there isn't really to many options out there. The clevo is a VERY heavy engine and love's fuel. Can make ALOT of torque though. The fuel injected 302 won't have the torque required for 4wding unless you want to rev the hell out of it, which they will do happily. and the new 5.4 quad cam are a great engine but trying to get one at good price would be hard. Also room may be a issue.

[cac]

to the best of my knowledge, the carby fed V8s used in the commies and falcons were all built before 1989....and IMO trying to put in an engine built before your car was is not worth the hassle...

the chev silverados of the early nineties i believe used a carby fed 5.0L, so that might be worth a bit of investigation....or toyota do have an older 4.0L V8...used on the toyota centurys of the eighties....its a 5V series engine....and as far as i can find, there were both carby and EFI versions available

[sco_aus]

Well you can carby a 1UZ due to their shitty wiring system or use an aftermarket computer. The main problem with them is they are really restricted from factory, but once a few mods go on, they haul arse and are an awsome engine. Light, reliable, plenty of parts, infact they weigh less than most 4 cyl engines due to being all alloy. Just a thought.

[strom]

if interested I've got a conversion kit for a 351 clevo for sale. Almost ready to give away. The reason is I'm going from manual to an auto.

[60 Jake]

mate if you decide to go the 308 holden donk i have a set of extractors to sell for $100 if ur keen.No pressure

[DISCO FEVER]

I agree with the Lexus vote. Check out this link.1uzfe Q&A, 1uzfe information and swap (http://www.lextreme.com/1uzfe_info.html)

Don't put other people off Cruzer. If I can run mine in 45+ degree heat in the Pilbara running 110km/h all day with the motor sitting on 89 degrees I don't know why yours is running hot.........and that's running a turbo......thought I had an issue till I found the viscous hub was gone.......poor Greg ( brunswick Diesel ) forked out for a monster radiator and it was the viscous hub the whole time, wasn't cutting in, hasn't since the day I drove it home and even then it was only running warm???????? Mate round the corner has the same set up in an 80 series (got ours done at the same time) including the turbo and no heating issues. There is about 25+ conversions done by Brunswick Diesel in Tom Price (Pilbara) and who knows how many all up in the Pilbara come to that...........they are running fine according to Brunswick.

As for oil maybe your putting it in the wrong hole:D

Rattly??.....I'll post what mine sounds like, and as for technology they were built and designed from the ground up as a diesel for abnormal abuse in mind.......the army being the big winner. Look into the make up of these engines and the reasoning behind the design and you may think otherwise before posting a reply of such. Half the postings on these motors here is absolute shite by a small few people who know everything about $*!# all. If you can't get yours right don't throw a tantram and put everyone else off.

If a plane is missing a wing it won't fly, sounds like you have been missing a wing from the start.

The 6.5 TD is an awesome motor and a pleasure to drive on big trips with nearly 400 cubic inches of diesel to play with.

I can tell you for a fact if the 6.5 ran hot no one in NW WA would have one. We will prob see temps of 40+ everyday now for 3-4 months apart from when a cyclone arrives, the vehicles would be useless. We have already had two 47/48 degree days in the last week.

Maybe Brunswick know what they're doing cause everyone up this way is cruisin.

They do the 75s also? I would not change the motor in mine for any of the motors mentioned. We did a rock crawling track a while back, the mate had the new 3L TD Hilux.
By the end of the section his clutch was just about smokin, the smell was pretty bad. The shorty crawled the entire section in 1st low in idle, I didn't touch anything......just steered.

On the open road when the old girls seriously heavily loaded to do the Canning and you need to overtake a triple road train.............. just plant the foot and your laughin, even dropping down a gear is a waste, 5th will see you round quick enough no probs.

On the beach/sand dunes nothing comes close torque wise. In Coral Bay I was doing some monster dunes that the quad bikes do when on tour, was the only fourby that did the monster dunes that day.......some of the approaches --to one dune in particular-- were very short, so once she got a little speed it was enough for the big diesel to hold revs instead of bogging down half way up.

Cheers...............motors a bit dirty, and the shiny bits need a polishing:D

Ok Crawla heres the full story on how this has unfolded for me. Now I my self am a diesel mechanic and have worked on just about and rebuilt just about every diesel engine know to man. So sorry I do under stand how these things work.

I bought the vehcile (HJ75) with a 6.2 in that was tired and I knew that when I bought it. real low oil pressure and was using a heap of oil. So got it cheap, and had intention's of rebuilding the 6.2 my self. Made a few phone calls to a number of people around oz and also talked to a mate of mine in the USA that I work with, who is also a diesel mechanic and he advise me to try and stay away from the 6.2. They had a habbit of breaking crank staff's. He also said that the 6.5 is far from a good engine, yes built to a military spec as a throw away engine. You break it you throw it out and get another. Much like the 2 stike detroit where back in WW2. But he said you keep the boost down below 15psi AND can keep them cool they can be a reliable engine. Keeping it cool was the main thing he said I would have prob with and yes he was right.

Having had alot to do with cooling systems with my own vehicle and alot of mates race or street engine I though how hard can it be keeping one of these thing cool be. How wrong I was.

I bought a new engine. Was advised what radiator and fan clutch combination to put in it and was told I wont have and probs with over heating. So out came the credit card and over came a new engine rad fan clutch, out came the 6.2 and in went the 6.5. Fired it up ran like a pile of junk, it had a stuck valve and was back firing up through the intake. That sorted it self out and off I went for a test drive. Nice cool day mid 20's and what do you know it get's hot real hot. Real quick to. So I rang the crowd back and they said no they don't get hot there must be some thing wrong with my set up. At this stage I had checked all the common things like air flow into the front, air out of the engine bay, air turbulance in the engine bay, fan going the right way no blockage in the cooling system and all seemed ok. I had roo bar off, bonnet off, even went to the extreme of taking my air con condensor out of the front to try and get more air flow into it, but nothing worked. So on the phone again. Still getting hot. Telling them there is something wrong in side suspect cracked head. As i said I have a mate in the states and he has played around with most thing's and he expalined to me that yes they always crack the heads around number 7 and 8 cylinder.

So the enigne can out went back to who I bought it from and they said they will strip it down and check it out. Got the motor back and was told that its all ok. Put it back in and it got hot. Back on the phone explaining this, so it was decide to try a new water pump. So over came a water pump and on it went. Same thing still gets hot. So on the phone again. Ok we will try a new injector pump. Put that on and still gets hot. By this stage my patience was really starting to run out as I could not drive any where with out it trying boil its brains out. So it was decided to try another new engine. so over came a new engine and in it went. Same thing getting hot. Now i'm really starting to get dark. As i can't drive it any where and I spend all of my time off working on this thing that is meant to be the beez neez in 4wd engine conversions. I kept persisting with it for a couple of months trying just about every thing know to man, and nothing would fix it. I eventually got onto some one that actually gave me some light at the end of the tunnel with what goes on inside these thing with there cooling system and inearly had a heart attack. So I went and bought my self a 6.5 that was stuffed and decided to pull it apart and have a look for my self inside. Well what can I say the general has completely missed the point here some where. Worst designed cooling system I have ever seen. They will alway get hot and crack head around number 7 and 8 cylinder as there is very little water flow around that area, which is also the hottest part of the engine. Now General motor's knew this so they up graded the water pump from what I believe was around a 70 gpm to about a 130 gpm water pump. All this done was put a band aid on what they knew was a major problem and would cost them millions to fix. All this is doing is forcing that much water around the engine that it had to get more water to back where it is nice and hot. And yes they would then run cool.

After find out this info I decide to fix my engine my self with a few different water passages inside the cooling system. Pulled the heads off and nearly had my second heart attack. This engine had about 5000km on it and it looked more like 200,000km. there was alist as long as my arm of thing wrong in side this surposed NEW engine. Now I'm REAL unhappy and just about ready to get in my car and go visting the fella with a large bat that sold me this engine. :mad: :mad: :mad:

Now it has been a bit over 12 months and the motor is out again So once again the cruiser is sitting in my shed with it's nose in the air as there is a very important part missing from it AGAIN. Must admit I'm getting good at pulling a 6.5 out of a HJ75. Doing it in record time now. :D

Now I'm not trying to put any one off from buying one of these I'm just pointing out a few fact's on these engine's and how they are not all they are made out to be, BUT with a few modification's (Which I am in the process of doing) I believe they could be a good engine not great just good. And they will do what most people can throw at them all day every day. There is no engine out there that is perfect (I'm glad there isn't other wise I would be out of a job real fast) and every engine has its own little prob's. As I said I have work on most diesel engine's and have come across alot of thing that make you think. WHY would the manufactuare do that.

So this is why I am a little as one could say anti 6.5 chev at the moment. It has cost me a fortune and I still can't even go for a drive in it with out boiling the water for a cup of nice hot tea, or if I wasn't boiling the water I was pulling the motor in or out.

Now I can see how you would be real happy with your as in your set up it would be great. Go A hole lot better than the old H motor be just as good on fuel as your not flat out just trying to maintain the speed limit and yes I must admit the exhaust note is great. You can't beat the sound of big cubes working hard. I am actually really looking forward to getting my engine back together and seeing if the mods that I'm doing to it will fix the prob (Geez I hope it does) and then going for a good drive in it and not having to worry about the temp gauge tap dancing with the Hot mark.

Dam the forum just told I had written to much. Must be starting to dribble s$#t :D. I believe you when you say that yours runs cool as I have a mate back home that has had one in his HZJ75 for about 5 yrs now, non turbo and use's it to drag his 3 ton boom spray around and has never had any over heating issues at all. He loves it and that is why I bought my ute. His engine was a brand new one straight out of the States so it has the 130 gpm water pump on it.

I know what the temp can get like up there spent the last 4 yrs in and out of there. Actually up here at the moment.



hope I haven't dribbled to much.

Cheers

Cruzer.

[crawla]

unlucky bastard, I can see your frustration. 15psi boost, that's a lot of boost hey! They came out with 8 psi stock if I'm correct.............is enough for me!!
Good luck with it all!

[6.5Cruzer]

unlucky bastard, I can see your frustration. 15psi boost, that's a lot of boost hey! They came out with 8 psi stock if I'm correct.............is enough for me!!
Good luck with it all!

If you get the 18:1 compression rartio pistons I believe they can handle around the 12psi happily but no more than 15 as long as you have a real good after cooler set up. Looks like you have a water to air on your which I think work as good if not better than air to air. Yeah it has been a long hard struggle but as I said hopefully I get it sorted out when the motor goes back together this time. then i'll be :truck: happily.

[crawla]

look at cummins/powerstroke diesels, they run low compression to safely run higher fuel and boost. Good luck with sorting the motor. An interesting read for you would be the power project on the diesel page.com.
Cheers. I do run the 130gpm with the twin high flow thermostats. Radiators overkill.....alluminium 4 row 16mm tubing running 30-35L with a 12 blade fan.
water to air good for what I do, air to air would be better for highway work.

bit of a hijack now...........will leave it there, interesting to see how you go.

This thread reminded me of another one, Les Addison is prolific on advice about the Chev 6.5 TD.

http://www.4wdmonthly.com.au/forum/f10/chev-6-5l-diesel-engine-tips-tricks-23850/

[stets]

i could jump in here in the equation about the reliablity of the chev diesels, but i think we have hijacked the thread enough, but i will say the chev has proven a good donk to me

[zoomer]

Small block chevs are faily easy to come buy and fairly cheap but I'd not be put of by the computer stuff. I have a carb on mine and there is no 2 ways about it , it's a pain when the going gets tuff. On the side of strength in the standard toyota gear I haven't had any dramas at all.
