Outer Limits 4x4 Board

am looking to get a gu wagon for my next car, and after driving the father in laws cruiser with a 6.5 chev diesel in it, am pretty keen to do the same.

are the 4.2s,3.0s,2.8s all the same besides the donk, if so will then find a cheapo and put the chev in it.

has anyone done this willing to shed some light on the subject

cheers

am pretty keen to get a 3.0l auto and chuck the 6.5 straight up to it, can this be done. also any difference in diff ratios between the 3.0 and 2.8

conversion is $23,000 drive in drive out when I was quoted 3 odd yrs ago. The g'box will need re-enforcing
Think long and hard about it.

Also search for Duramax and Alison Auto on here.. MUCH MUCH MUCH better conversion....

Not too sure the Duramax fits in...? Could be mistaken, but I thought it was a little long.

I put the 6.5 into my GU. LOVE IT! Does cost a bit of coin to get it done by a shop (I used Brunswick Diesel). I would do it again, as they have given me good after sales service.

The gear box does not require any work. There are two options to fix the gearing to suit the Chev - either replace the 5th gear for a different ratio, or swap the diff centres out (front & rear). I went for the diff option, and Brunswick swapped them out for fully rebuilt units (the original rear diff on the ZD30 is a different size and you can't just do the diff centre, you need to replace the whole unit).

To do the conversion yourself, I would look at the 2.8 or 4.2 as the donor. There is less electrics to remove/bypass than the ZD30 (you still need the computer to do other things in the chassis/cab).

Did I mention I LOVE it?! A lot of coin though! $23k plus transport from Sydney to WA and back (the engine was blown, so that was my excuse for the missus).

yes they will fit, Heath however has had quite a bit choped out of the firewall and re-plated behind it. Mainly to fit a 4" dump pipe and for better weight distribution.
It will fit in a standard bay but will be tight.
Also would be more than $23000

HE is working out prices at moment.
He has started a bit of a thread here.

slightly OT, but what about a 7.4 powerstroke?

Go the brunswick,I did this conversion 15000 k ago,awesome difference.
12L/100k towing or not
$24000 drive in and out,my zd30 had a u/s fuel pump and they still gave me $4000 for it.
Diff pinions + ring gear changed to petrol ratio(3.9 I think).
1950rpm at 110kph.
2.8 G/Box is the only one not up to the task,3 + 4.2 box are the same and can handle it.
Hope this is helpful

Cheers

A td42t with with the right turbo will make more power. I have seen it. The 6.5 chevs a a strong engine. But going on what I have seen I wouldnt do it. I dont think the conversion is good value for money.

thanks all for the info, have thought about it a lot and think for the money better off goin a td42t, would be nice havin the 6.5 chev but for the money, think im gonna get a camper instead.

the price usually scares most off. me included.

$23k on a TD42 would be
