duramax in GQ or stick with td42

[THE-Burger-Ring]

as most aware of my previous posts i have the TD42 in rebuild mode.. currently running 190rwkw.. as we all know there is next to no reliability with that sort of power in td42.. was hoping to get people oppinions on duramaxs? if anyone has done it? whats it roughly worth for conversion and motor alone.. what sort of power to the put out? and everything else i should know if i decided going that way? chances are i will stick to td42 and change internals but i am trying to weigh up options.. see whether or not its worth changing everything all together?

Allow around $35k for duramax. Could probably make your td42 reliable for that.

Just got my GU back on the road with the duramax. Awesome to drive, could never go back to a td42. But still in early stages of tuning, reliability etc. But so far so good. And I have approx 420 rwhp on tap at the same time as an economy mode. Possibilities are endless with these things.

[THE-Burger-Ring]

what sort of longetivity will you get? that sounds absolutly awsome..
and what do you consider economy?

[coxy321]

Have you had a look a Heath's GU build thread yet?

Here's the link:

I say go for it, but you'd have to better Heath's effort, of course.

Mmmm Thats a little more than I the early estimates. I Thought they where original talking under $25g, which when compared with a decent powered TD42. Makes the duramax worthwhile. But at an extra 10g, a moderate tune on the TD42 is worth it. Well for me it is when really I would be happy with the 150-170rwkw power.

Just wondering what extras you went with or was that just putting the duramax and auto in with associated wiring and plumbing?

gudday

35k is very expensive, I have been researching a Dmax build, and tops its about 25k (kiwi dollars) with a second hand box and engine with about 70k miles on it.
But the big question is are you doing it your self or paying someone i suppose.
For 35k Aussie dollars you could build an 650hp weapon for sure. But if you're only looking for 170kw you could easily make the 42T strong and reliable for $7 - 10k.
Who else has done one besides heath?

[heathgu]

Everyone that thinks it expensive at 35K, then they should do it. Give me some feed back!!! If it was so easy why has no one else done this??? I am not having a go at anyone, i just dont understand people who want everything but dont want to pay for it. YOU GOT TO PAY TO PLAY.

This is not an LS conversion. Anyone out there tell me what engine platform they can install, makes 500rwhp, 1000ft-lb, easy to drive, tow anything, good fuel economy. Have switchable tuning on the fly. 6-speed auto. Oh and if you want to have 1000rwhp it can be done. ????????????????????????????????

25k doing it yourself with engine only/ no trans is a maybe. Try finding a clutch (then let me know a price?)

I am tired of people say thay can get a motor and trans for this. Dont tell me just do it. I did, i didnt let anyone tell me it cant be done.
Also to all the people who expect me to roll over and tell them how to do this. SORRY. Its not happening, So please stop calling me. Unless you are completely committed i am willing to help but its not free. Nothing is for free.

If i am wrong them i am happy to hear anyones thoughts. I got one already, and i have 2 more engine here. SO i am not fussed. So until anyone does it and tells me 35k is expensive please stop saying it is.

[Duramax dreaming]

Fair enough Heath
We are starting our conversion into a GU coil cab the week after next (I hope) here in WA, will let you know how we are getting on.

[garth]

YOU GOT TO PAY TO PLAY.

Yep...cant argue with that!

[vanbox]

Hear hear heath.

Ill admit when we first were crunching numbers I thought I could do it for 25k tops. I helped out ith labour where I could, but the brains was heath, and like he said, if its so easy and too expensive, why arent there more of them?
As I said you can have any combination of quality, parts etc, all depends on what you want the end result to be.

As for saving money using a manual, haha, you will spend more on clutches! I would be interested to drive a manual, but think I would hate it they are such a slow reving motor, I'm in 4th before 40kph.

Will a built td42 get 13L/100 with 170kw? I get that with 250kw!

This is not my creation, so contacting me won't yeild much either. Im not going to give away or take credit for anything heath created.

Totally Agree with all that, Yes they are expensive, But look at what you get for your money as said, nothing else will compare.

Having been involved with fitting these engines with heath, I can tell you there is a huge amount of labour involved, as well as a huge amount of parts. It all adds up pretty quick. And don't ring me asking how to do it either, You can ring me if you are looking for someone to do the conversion, or looking for a wiring harness to suit.

In comparison I charge $18000 for a LS2 swap, that will never have the economy or power of a duramax.

Could bolt two LS2's together for the same price as a duramax! But ill stick to diesel.

[ledgend80]

little off topic but are uses running prognostics on the 1000/2000 series transmissions. and for 35k are you getting allision doc with that for diagnostics purposes.

[THE-Burger-Ring]

well look guys i a keep hearing people say for 10k you can make a 170rwkw td42 bullet proof... well i have a gq patrol that weighs 2.9 tonn. 4.3 diffs and with the 35's makes 190rwkw... Its pretty simple i cant afford 35k so those people who say its easy to bullet proof my motor speak up.. cos all the research i have done and motor rebuilders tells me i will roughly get about 100 000km to a motor and that includes, EVERything ceramic and teflon coated and port and polish. rings i cant seem to find any good shit.. con rods arnt going to make any god damn difference, water will still smash them. The motor breathes very well there is not restriction anywhere. I have never reved motor out behond 3500rpm. simply cos you dont need to. empty car with rear locker in breaks traction at 90km/hour. so i have never needed to scream my car to 5500rpm like some clowns do. i like 190, i just want to drive it with confidence.

[tye1986]

you could try swafftech diesal long way up in qld, but is really good to deal with and knows his stuff.

[THE-Burger-Ring]

i already have a workshop rebuilding it but i need more ideas to consider.. as far as i am concerned there really is not much more you can do bar smash the air and fuel in. then minus reliability.. in a perfect world i would sell my misses house and buy a durmax lol.

[5inchgq]

Swaffie has his race truck that he uses to compete in coopers etc it has 300rwhp and 860 ftlbs of flywheel torque might be worth a phone call, he's a great guy and knows his stuff with TD42's.

I think Heath is the one to talk to about td42 reliability, pretty sure he spent about 20 - 30k on one and it still ended up blown up. Not really sure on the details though.

[turps]

Dont take my comments of $35g as being not worth it or it can be done cheaper.
After doing some research myself. The engine and auto seem well worth that kinda money to have it reliably installed into a patrol drive in drive out.

I was more meaning that for me that may be a little out of my price range. I was initially looking at a break down of cost of a full good rebuild of a td42 is around $12000, I think that was with a upgraded pump. Then I was working on $10 000ish for a turbo/intercooler install.
With those figures I thought an extra 3g for the duramax hell yer spend the extra. But at $13000 more. I cant afford it. Hell I cant justifie $22 000 for a good TD42 setup now
But if I had the coin. I would be onto it like a fat kid onto a donut.

Just for interest. For the approx price of 35g. What kind of adjustable tuning does that give you. From my research its possible to get the power adjustable upto 150hp from stock very easily. Those kind of setups, are they possible to have a power mode then just flick a switch and it changes to a economy mode.
Was just thinking for a tourer. I would be doing lots of kays on transit sections whether it be high speed tarmac/HWY of fast dirt like the Birdsville Track etc. These areas the std HP would be way more than ample. So and economy tune would be great.
But then deep or soft sand in the Simpson or climbing long hills with a load on board. It would be good to be able to flick a switch while driving and getting a power setting.

Is this possible on your STD install. Or would that require additional goodies to be brought.
Also how is the shifter setup?
Does it look like a std Auto shift P-R-N-D-5-4-3-2-1 or is it like a shifter on a Falcon where it has P-R-N-D then the + - thing off to the side and just a tap either way manually changes up and down the gears.
Tried looking for Pics of a Chev setup but cant work it out.


Just thinking long term I would like to get a GU Wagon (family car). And just getting ideas of cost

[vanbox]

I have a standard tune of around 300hp with 5 progressive settings to 420hp at the moment. The standard auto transmission is good for around these figures.

Im getting another allison built (over built) to handle more power. The stock standard motor should be good for up to 600hp at the wheels without any modifications, just a the right tune. I have seen a stock motor make 970rwhp but threw a pistion out the side of the block eventually.

The biggest restrriction will be airflow. There isnt much room under the bonnet, and I only have one air intake hooked up. Its too restrictive on standard tune. Im trying to put together another air intake system in order to plumb a secondary box in.

As for auto, I have a shifter from a wrecked ZD30, which goes PRND21. The allison is setup like, PRNDM1 (M being manual mode). So when in M mode, I have a toggle switch next to the shifter to go up and down gears.

[vanbox]

As far as I know, all chevs have column shift autos, so you might have trouble finding pics of their auto shifter layout

[killalux]

Pretty much what paul has said.

As a standard install we fit DSP5 switch, which gives you 5 different tunes switchable on the fly.

Shifter setup is PRNDM1, using either a B&M shifter or modified nissan shifter for factory look. in M you have basically a tiptronic mode, usually use a rocker switch to shift up or down. However this is only an option on the LBZ, not LMM (yet) due to more complicated electronics. With the LBZ (and soon LMM) you also get factory chev cruise control as standard.

Hey Steve do you think it would be possible to run the 4.8 shifter with the proper tiptronic setup (you know the type that you just push the lever to the side and go up or down)

[killalux]

have not actually seen one to be honest, however we have looked at the ford tiptronic shifter which can't be used. Problem is that you need to pull the shifter cable down to engage M mode, where the tiptronic shifters just slide across without moving the shift cable.

Have seen a couple of cars with M mode below D. But they shift left-right not forwards-back. Dodge Nitro has it, cant remerber what else I have seen that kind of shifter in.

Piglet thats a bit of a big call. When the only other person we know of doing them is Heath. Sorta insinuates that he doesnt do them rite.
Seems to have made some reliable installs so far. Thats not to say Glenn isn't doing a good job either. Just this is the first time he has been mentioned.

Sorry didnt want to tread on anyones toes.by saying, If you want it done rite give grinna a call.( I should have said see the experts, like Heath , & Grinner has been doing them for some time aswell.)
I was just trying to say ,If you are going to get a job done, go to the people who have done it before.people who have found out what the issues are by testing them under extreme situations. & rectafied any issue that might arrise.
people like Heath & Grinner (& im sure theres a few others that have been down this track) have learnt it & are willing to help & or just advise. A DURAMAX CAN BE A BIG OUTLAY, SO GET IT RITE THE FIRST TIME.
I wish I could have one (think ill ask santa)

I know what you mean there. I would love one and I think a GU wagon with a blown 3lt would make a real good platform. But the needing a Body lift is of concern. In a GQ it doesent bother me. But I think a GU is much better with only a susp lift. That and the airbag issue, that some authoritys have an issue with.

In Qld, there is no issue with body lifting a GU with airbags you just have to go about it the right way. You have to apply in writing then get it checked over the pits. I went through this process with my series 4 gu wagon and it is fully certified with the stamped letter of approval in my glovebox.
