View Full Version : Source for Duramax engines?
I want to put a Duramax in a GU for a mate. Can't seem to find anyone selling them in Aus.
Want one with an Allison box.

Hell yes.
/subscribed.
i'm not massively into the diesel thing but isnt the cummins generally regarded as a better all round package? how come you'ev gone with the duramax?
I haven't gone with the duramax, I can't find one.
Fill me in on why the cummins is better?
bullet supercars in yatala imports them

This is relevant to my future interests
just from what i've read about diesel tuning in the states, albeit limited, those cunts love the cummins, a smaller few like the duramax, and noone likes the powerstroke lol
done some googling and can't seem to find any of the specifics i was looking at before. but i was under the impression you could get a cummins thats a little lighter, a little tougher, and a little easier to get power out of when comparing to a duramax.
also there is a mob that always advertises in just 4X4's or 4X4 trade magazine. they have a list of heaps of different diesels (well, heaps of variations on the big 3) and have list prices aswell, from memory they were pretty expensive though, although this may be a diesel thing in general (i'm comparing the price of a motor to that of RB's and JZ's). anyway, maybe just pick one up and have a flick through next time your at a news agency.
also i remember seeing a build thread on here about a guy that put a cummins 4bt into his f100/150. might have been turbo351? might pay to have a quick search of that
edit - this may have been the place i was thinking off, probably dont supply duramax's etc but can't hurt to try http://www.brunswickdiesels.com.au/new/services.php

DOHC 5.9l cummins from dodge ram ftw
Cummins ISB CR weighs 500kg, can't se the Duramax being more than that.
I can see that the Cummins is a good engine but if I can't get an adapter for the transfer and the engine is too long to fit then it is a moot point. Duramax fits, make bulk power and torque, has good aftermarket support and is a V8.

for the price, why not rebuild and bomb the fuck out of the TD42?

Duramax will put out 500rwhp with just a chip and has been done before with great success. Why choose something different?
It doesn't have a TD42. He doesn't even have the car yet. 6.6l > 4.2l.

What's wrong with the powerstroke? Serious question.

aaaah I see the issue.
mental note, buy gu with blown 3 litre aids diesel, send to jzk25 w/ $50k cash money for duramax pro love.

Powerstrokes are pretty old school compared to Duramax. The one I have dealt with had issues with the turbo pedestal and oil pump and would not go. It was basically non turbo.
The injection system on them was pretty cool prior to current common rail setups though.
Can't see $50k in it, maybe $25k. No way you would go there for $50k

Another fella with one - shows whole build with a little detail
http://www.patrol4x4.com/forum/members-nissan-patrols-19/my-duramax-gu-4-a-57239/
powerstrokes are big bucks to get cranking along, they run a secondary oil pump to actuate the injectors (google HEUI for more info)and its fuckin hard to get the oil pump to deliver the flows required to push massive injectors. it can be done,but its frikken expensive.
i`d be pretty amazed if a cummins 4BT/A or 6BT/A would fit in a GU without either a body lift or bonnet bulge. 6bt 5.9 is tall AND long. good motors if you are prepared to do the work to make it fit. quick google search on 6BT 5.9 throws up 34inchs long without fan,38 with, 32 inchs tall bottom of sump to top of rocker boxes,30inchs wide, oh and near on 1200pounds
which gen of duramax engine are you looking at LBZ,LLY,LML or LMM? be warned the newer versions have SHITLOADS of emissions crap and DOUBLE SHITLOADS of electronics to make it run.
I've heard a bit about that drag ute from Steve, seeing the pics is just awesome!

im pretty sure i can tune all the range of duramax engines.. they are fucking good things...
In a previous job, we imported them - in Chev / GMC pickups.
With a tune and 4in exhaust they would do 0-100kmh in 6.xx seconds (hand timed) in the 3000kg truck.
Awesome engine.
I think 06 is the first with the Allison. LLY from memory.

rams have fucking tiny engine bays for a truck, if a cummins fits in one of them, they will fit in a pootrol.
duramax will be cheaper and still over powered for the patrol though, so may aswell keep going on that line of thought
I think 06 is the first with the Allison. LLY from memory.
They had the Alisons with them earlier than that. At least back to 03 when I was playing with them...
Maybe performax in gympie as they deal specifically in american imports.
I think the cummins is recessed into the ram firewalls a fair way. They are a big piece of iron.
possibly try superformance at capalaba, or linquip at brendale http://www.linquip.com.au/ they import shitloads of chev diesel V8`s (6.2&6.5 much cheaper than duramax, much less of an engine too),would probably be able to track down a duramax&allison pretty easy
i originally wanted to put a 4bta/3.9l cummins into the hilux, because they`re cheap and strong, but the height was a big turn off 945mm Vs 750mm on the isuzu 4BD1t (also 3.9),the 4BT is about 30mm shorter&110mm narrower than the isuzu,but that 200mms taller makes the difference between an engine that fits pretty easy or a colossal headfuck.
One day when i'm rich one of these is going in an kingswood tonner.. I love these things to bits...
I don't care if I have to jump through every ICV hoop and register it as a purpose built tow truck or something..
According to the skywest in flight magazine, performax will see you a brand new base model RHD Silverado with one of these already in it for $80k...
how much change will you have from $80k after converting a GU and engineering it etc. etc.?
although you'll probably weigh 30% less in a GU... and have a boot instead of a tray, and 5 seats etc. etc... and an imported suburban with a duramax (or dual cab silverado with leather and stuff) will probably run higher than that fairly quick..

A place down central coast does them drive in drive out for around 40k engine supplied. Thats half the price of a silverado, and a blown up 3L GU is only around 3-4k.
having done the 4bt cummins swap, and being in the process of another i reckon the 4bt in a patrol would only be ok. gearing it high enough would be a drama and the cunt is 3 feet tall ! a 6bt is too fucken heavy. the b series cummins motors seem an awesome thing though.
from what i can gather gm designed them to make mounts and shit all the same, so anywhere a sbc will go so will a duramax. aren't they all aloy too ? i spoke to a bloke at powercruise with one in a patrol and he reckoned it was easy to fit and awesome.
the 6.2/6.5 things brunswick diesel sells are overpriced pos from what i can gather.
the 6.2/6.5 things brunswick diesel sells are overpriced pos from what i can gather.
Hence the reason why any old truck for sale with an old Chev diesel is priced like a brand new V8 diesel cruiser. They must have been raped on the conversion.
In that duramax GU thread a bloke mentions that bullet sell duramax and old chev diesels. Old Chev 6.5 rebuilt with blower, $47k drive in drive out. Lolwut.

$30k USD new. Surely a new GM spare parts engine/trans/loom/ecu would be less than $10k USD?
Else employ a grinder monkey to chop a low mile one and ship ot Oz.

yeah 3 cylinders or so. its not that they are recessed into the firewall, chrysler brought the windscreen heaps forward on alot of their cars around 94-04ish. "cab forward" design iirc

pretty sure thats the one linked on previous page

I really need one of these now, the dirty RD28's injector pump is fucked.
Found a 7.3 powerstroke for sale for reasonable money, what's the consensus on these?

It's 7.3 litres. How bad could it be?

Powerstroke 7.3 is a BIG motor. I'd be running the tape measure over everything 30 times to make sure it will fit.
Other than that I reckon they're an untapped resource because everyone is all 6.5 Chev this and 6.6 Duramax that. The Powerstroke 7.3 was one of if not the main cornerstone of the US diesel tuning revolution.
Even look into the latest 6L Powerstroke.
the 7.3s are fucken heavy. like 600kg. and big. and the heui setup is gay for more powahs after a point.
It's 4k for the engine,auto,radiator,tailshaft etc. Fucking cheap compared to Duramax.
MRMOPARMAN

theres quite a few duramax's on ebay USA for around $6.6k. better than what the aussie retailers are selling them for (by a fair margin)
depends on how long your willing to wait for it and how fucked you can be dealing with shipping i spose.

Drove a F350 with a 7.3, towing a 30ft box trailer with a small race car in it... Epic grunt. Was funny smashing SS utes towing similar race cars on open trailers up hills...
powerstroke`s are nasty to get powered up, they use HEUI -Hydraulic actuated injectors, driven off their own oil pump,getting enough flow from the HEUI pump to push huge injectors is a very large, very expensive issue.
it can be done for sure,but big money to do it.
6.2 and 6.5 GM V8 smokers are mechanically strong,but have terrible flow and $ per HP (compared to the duramax,cummins etc)
There's an LB7 on ebay for $9500 that has been listed for ages. Might have a look at it but it seems a little sus, doesn't start, claims to be low kms but the seats are fucked etc.

no, they're not. i've seen photos of them with 3 piece cranks and multi piece blocks.
Looking at this one.

Ad is a joke, Az is going to go and look at it and interrogate the guy.
Az checked it out and said it was shit. Might still be worth an epic lowball though.
can't bring one in straight from the states? they turn up for around $4k with an allison reasonably frequently.
Got a 100k mile LBZ coming over from Canada. Should be here March.
nice! Was it a complicated process? Will you use the same contacts again?

Who's that?
Got the engine finally. It's a big sucker. They appear to be built with every known restriction available, no wonder they respond to mods so well. Needless to say I will be binning all the gay shit and perhaps compounding with a 4088 if the owner allows me/turns away for long enough.
Cool, make sure you do a thread.

awesome. keen for pics. lots of them
Restricted manifolding you mean?
Dual TD06 20g SL2's into 4294.
You know you want to. You also know where the free td06's are.
where are the goddamn pics! :p
Restricted manifolding you mean?
Yep, shithouse exhaust manifolding(but acceptable for a diesel) and more shithouse inlet manifold.
Haven't got any decent pics yet, I am going to strip it down to it's jocks and take some pics.
Would love weight and dimensions as well if possible. Keen to see this project get going.

FWIW I have a mate who has one in his F350 with the gas injection thingo on it. He has run it from end to end and side to side of the country the hard way and as I understand it the only major issue he has in in what would have to be near 10 years has been ripping the front end out on a dune or some shit.
Its life has been split 50/50 crossing the country/ towing a 3.5t bob cat.
the power is impressive, but it is the reliability of the thing that is really impressive.
Awaiting these bits to be for sale. Looks like I might be fitting the Dmax to my own TI patrol instead of mates shitty RD28ST. Twin GTX2860s on custom manifolds, top mounted WAIC.
This is some really nice stuff.
