LBZ Duramax in a 130 Extra cab ute

Hi Folks,
I thought i would start a build page on this forum. I have been fascinated with what you guys have been doing with the LS1/2 combo's in your defenders so thought i would show you my 1997 Defender. I have owned this vehicle for about 12 years and it originally had a 300Tdi motor. I ended up blowing up 5th gear and was due to go to the US for a holiday so thought i would bring back a Duramax/allison. I had previously started another project with a 2001 130 with a LBZ but that's another story. I got the actual conversion finished May 2014 and pulled it off the road January this year to do a full strip /refresh. I also want to put a decent AC in it so playing around with dashboards also.

Very cool! How hard was it to get the engineer certificate? You could do one in a 6x6, pick a non-operational one up at the minto auction and stuff a duramax in there, might fit a bit better and you will have the leaf setup up in rear to carry some weight.

The engineer has viewed the vehicle and is happy with how i have done it, just now to go through the formal process. I am stripping the vehicle so i can galvanise the chassis so will have a couple more visits to see him to get it signed off etc. I would love a 6X6 but have just bought a RFSV 110 instead! This 130 is my daily driver so its the perfect size.

See the oval window behind the front door window? He added that length to the bulkhead/pickup cab roof for a little extra room in the cab.

Not many of them around but gee, it makes a huge difference to driver comfort.

Wow - very cool build.

That LBZ must put out plenty of power to move the 130 down the road easily enough! Did the LBZ need a lot of wiring / ECU mods to work with the Defender?

The LBZ certainly moves it easy. I just love the torque of the motor and thats running a 1:1 transfer case. I am using all of the chevy wiring at the moment sbut when i rewire, i will use BCM etc and minimal land rover wiring. My idea is to use silverado instrument cluster etc.

New Dash & Vintage Air heater A/C

Been plodding away installing my new dash. Drew it in Inventor and then had alloy water jet cut. I wanted to use the duramax instrument cluster so was a battle to get it all in. As my ute is a extra cab, the seat is a lot further back so it gives me more room to play with.

I also have made a new exhaust as wanted to go away from my original twin 4 inch so made a single 5 inch system. I got a muffler from Summit racing as basically there is nothing available in Australia. Once the vehicle is stripped i will fully weld it out. Getting close to finish my Fab work at long last! I haven't been behind the wheel since January so been a while!

Ive been waiting for one of these to pop up. It makes a lot of sense. But also no sense at all. Love it.

Looks great, Gaz - once you get done, have all the bare metal powdercoated black...it will definitely improve the appearance!

Over here in OZ they all drive V8 diesel Land Cruiser so rather than be a sheep and follow the pack i had to go bigger. People just don't expect it from a Land Rover.

I'm going to get the chassis hot galv dipped. Everything else will be repainted also.

This is a great project! Have you done any work to the chassis to stiffen it up, and how are the axles holding up to all that extra power? They are a great engine, quiet, small, lightweight (compared to a 6BT).

Thanks mate. I plated the chassis from the front coil mounts to the 1st cross member under the transmission with a 5mm plate on each side. Drive line has been fine so far with over 350 kilometres on them. I have upgraded maxi drive axles in the back and managed to get one of Keith's 1.5 inch axles (to go in yet) before he stopped making them. Im thinking about going to a D60 front later but no rush at the moment. The Duramax are certainly a smooth motor and the Allison just makes it a perfect combination.

The Allison just seals the deal, for sure. I'll be watching this one!
