Yes..... I've been dreaming of the time I'd take the old SUPATRUPA over to Brunswick Diesels in Perth or up to Qld and say "Chuck a V8 diesel in the old girl... I'll be back in a week or two to pick her up".... It was always a cost factor.... no change from $18, 000... phew!

But now I've got now choice. The 2H donk is dead. ... passed away a couple of weeks ago. It's sitting at Traralgon 4WD waiting my decision as to what to do. They'll fit the V8.... but then, the upgrading of everything else, cost and engineering needed.. compliance costs. phew!

The other thought [2H is not really and option.... the old girl DOES need more grunt]. .. is that a brand new 1HZ could be fitted and manage to fit under the compliance nazis' radar. The turbo could be carried over with some adaption.

Your thoughts please..... I will decide by next week how to spend the bank's money.

Will the 1HZ lift the performance sufficiently to cruise with the traffic and lug around a tonne of stuff in the back?

Cheers Royce

1hz wont fit straight in check out how much fitting will cost. 12 ht will but there would be extras to pay for and thse are a dear donk anyway. 1hz arnt the most powerfull of motor and you will still get blown away at the traffic lights (turbo would be dfferent story) 2h and 1hz motors dont take kindly to turboing coz they were never desighned for it (some may disagree but there is a good reason toyota made changes to these engines to take a turbo)

G'day Royce
Yes it's a big decision, 6.5l or 6.5l TD.
I've seen a few of these beasts in my travells and you should see the smiles on owners faces.
There's no substitute for cubic inches.
Safe travels

Royce, can I just ask why you would need to ship it to West Aussie or Queensland? Bearing in mind you are East of Melbourne aren't there places in Melbourne that could do it for you? Truckster usually knows a bit about the sources but you could look around http://www.outerlimits4x4.com/ for all sorts of performance and repower information. One good place is just off the South Gippsland Highway - Eagle Spares for a look anyway, for motors. Number 92....
Cheers,
Who?

I guess the compliancing nightmare worries me... and the 'out-there' reputation of these 'expert' fitters leads me to go for the advertized specialists.

Royce,

For romance(not the love 'n kisses one, the other one), go the V8. Only got to hear one with a big exhaust.....

But in an economic vein, try the 1HZ. They are 25% more powerful than 2H, so you will notice a difference. Then there's always the hairdryer.....and intercooler.

Like Davoe said, you'll get blasted at the lights, but they can hold 100 easily, in open road conditions. Then there's the spare parts.

But then, if the bank's paying, go the whole hog, and get V8.

Tough decision,
Hooroo...

Wouldnt a modern V8 petrol & taller diffs do the job at a third of the price??
Then have up to $12,000 to spend on fuel & other stuff! $18000 into an older chassis & reports of some problem areas with mediocre yankee engineering!
Unless U are doing massive kms?
Transmissions would take a beating with all that torque too & likely failures.

7.3 Power Stroke Ford V8 out of a F250/350 would eat either..
there is a good thread on this on outerlimits in the NIssan section

There is talk of a Cummins donk.. Now this sounds good, theres a RAM video clip I have here of one pulling 11 second 1/4 mile Drag runs!!

Here it is.
What about a 5.9L Cummins inline 6 common rail diesel (Cummins 6bt)from a current model Dodge Ram? They pump out about 235kW and 800Nm of torque from almost no revs at all.. Eagle spares in Dandenong was also the company that thought that they could get a new Dodge Ram Cummins engine

Now you've got me salivating.... but not really making decisions easier. All I'm after is comfortable cruising. I coudn't give a ----- about burning rubber from the lights or even overtaking, just reasonable open road and getting up slopes.... not even too worried about changing down all the gears for steep climbs. Still I'll follow your leads and let the dreams continue!!! :-]

I always advise people on conversions, use a motor/box combo that was comercially brought to Aus, ie, the 1HZ, 12HT or (i know their not diesel) a holden or ford V8. Anywhere you travel, getting domestic delivered parts, will be far quicker and heaps cheaper than odd ball hummer or dodge parts, that said the GM V8 diesels are sensational to drive but all too uncommon when it comes to parts.
Just my opinion. Be sure to let us know which way you go.

You're making good sense. I'm planning a couple of outback trips.... parts.... the 1HZ is looking better [with the hairdryer].

A 1hz with factory turbo out of an 80 series, will fit without all that much trouble, the exhaust is on the other side, and maybe get the gearbox that goes with it as well as wireing.

That way it stays all toyota so serviceing is never a drama.

Hello Royce,
There's an article in the February 2005 edition of 4WD Monthly about Mark of Mark's 4WD Adaptors in Melbourne putting a Chev V8 diesel into his own 80 series.
Might be worth contacting him as he's in your area.
He also had a neat looking air actuated overdrive on his 80 Series. It too was made by his company.

Geoff.

They both run the h55f box, but the input shaft on the 2h is different to the 1hz...i think they are a little longer too, so a spacer is needed with the new 1hz bell....and probably a custom clutch....the 1hz pressure plate and a 2h or 12ht clutch plate....ive heard of 1hdft's in 60's running the auto aswell. Plenty to do and change on any conversion...with a 12ht, its all bolt in, so id do that first. If not, the 1hz is good...there is one on ebay at the moment...look in the toyota parts section....maybe even a gearbox too...some import place up qld....
Will hunt around for you....if you decide to get the 1hdft it is in newcastle, and is from a rolled 94 cruiser...

Hi Geoff, thanks for the advise. Sorry to sound dumb.. but what exactly is the 1hdft.... how is it different to others, and what does it sit in normally? Thanks Royce

Where a 1hz will fit, a 1hdft will also...same block...one on outerlimits for 4500 dollars, he has the 94 gearbox too. If you wanted either of these, let me know and i will put you in contact with him.
What to do...i would pay to get it back to your place on a flat bed...and look for a wrecked 12ht in a 60 series look first at www.pickles.com.au...u should be able to get a 60 for 2-3k smashed, or rusted out
If you go the 1hz or hdt, you need a 90 plus bell from a 75 or a complete box, and your away.

hey dozer, is the gearbox on the hj 75 the same as the gearbox on the hzj75 ? I think not but am unsure. certainly the 80s have different g box and t/c. My camper actually is a hzj with all the hj running gear so stuff will fit but I dunno how much you can mix and match. saw a 12ht on ebay for 7,500 and it had 350k on it - thats just ridiculous surely. As you said a wreck wouldbe the way to go as you would then get the xtra parts needed (12ht and 2h while simular have quite a few differences especially with electricals and fuel injection)

Hi Guys
If have a 100Series Landcruiser with a HZ engine and fitted a sprintex supercharger for about $6,000. The extra power was great, about 40% extra according to a dyno test and the extra power was right across the rpm range.

Unfortunately the injectors were set too rich and I was pulling a trailer load of Chritmas trees and managed to blow a hole through the top on one of the pistons, the other pistons are cracked along with the precombustion chambers. Have only done 148,000kms, everything else appears to be in excellent condition.

I chose to put in a V8 Diesel kit from Brunswick Diesels. The engine looks great and on first start up sounds beaut. Still have to put in a new exhaust system. The kit was not complete and did not include any instructions which made the job very difficult and frustrating. If you go this way I suggest you get a complete list of what you can transfer across from the HZ, what extras you need to purchase/aquire and most important a full set of instructions.

By the way I now have a sprintex supercharger for sale, would like $3,000. I will add the HZ engine for nothing if anybody is interested.

Regards
Alan
