No stress on the videos.. I know everyone loves a vid! lol.
Cant say the 'rado. is mine.. work for a company that does conversions...

The Oka goes REALLY well.. certainly dosnt brake as well as it accelerates!!

If you need any info or diagrams.. dont be afraid to shoot me a PM and can either fax thru manual pages or happy to quiz the auto sparkys

Thanks for the offer of diagrams! Brakes definately would get a pizzling with the increased HP! I'll flick you a PM when getting closer.

Cheers

That oka is sweet, never thought to put a duramax in one of those. Can you post some pics in the members. Would love to have an actual look at this one day.

Hi Vern,
Have a look at this thread over in OKA land.

The OKA Forum :: Topic: Duramax / Allison 6spd / Nissan TC conversion (1/2)

He claims he is doing 16.8 second 400m, (half what it was with the Perkins), with a finish line speed of 134 km/h, in a truck weighing in at 4.86 tonnes. And struggling for traction off the line.

Thats pretty impressive! They are a beast of a motor.

Mmmmm, keep thinking Duramax and 101 in the same sentence... No, sorry. I'll be quiet! :D

Hi Gaz69.
Any more progress? Very interested now, as I sold the Pootrool, and have the 130 up for sale (just not using it enough, don't need 4 seats and shouldn't be using it as a daily drive when I have my imported TD Golf in the shed!).. My last post might have to happen now.... Well, in the form of a 220hp 6Bt against that Allison 1000 6 speed in a 101 (as I don't think a Duramax will physically fit between the two wheel arches/seats!!) .... Any pics of your handy work/conversion making that auto fit the LT230? Guessing you might have to use an Ashcroft Center Diff assy too... Looked into the front Salisburys too before I changed direction... Might be worth looking at the shafts in yours as I've since learned that its only the diff that's bigger... HyTough are still doing shafts and I believe he does them for a Salisbury Front... :)

Sitec,
No More progress as currently in the US on holidays. I did by another Duramax and Allison while i was here buts thats another story!! I have got 35 spline axles sitting on my bench at home for the rear and will worry about front ones later. Might need a fusible link somewhere anyway!

Cheers

Fusible link! Never heard it put like that before! Been looking at the Allisons myself... Allison 1000 6 speed with stand alone ECU so I can run it behind an older Cummins 6Bt with mechanical pump. Do know for a 24valve already coupled to a 6 speed but not sure I fancy getting my head round fly by wire diesel in a 1977 vehicle! America eh! Lucky bugger!! ;) Enjoy!!

Seen plenty of cummins, power strokes and duramax's while cruising the us the last 4 weeks. Amazes me when one of theses flies past me about 75 MPH uphill towing a 40 foot trailer! You couldn't go wrong with a cummins. The duramax's is certainly wide. I don't have much room around mine

Cheers

Hi Gaz69.
Well, progress has been made my end. Now have a 101 and a Cummins in the shed.... Sadly the Allison was not to be as a 101" wheel base with a pair of Salisburys leaves little room in the middle. The Cummins came from the UK with a 5 speed ZF gearbox behind it so I've made an adaptor to go between it and an LT230. I'm hoping to keep the engine in the correct place behind a slightly enlarged original rad. It'll give me a 400/500mm rear prop! With the spare wheels mounted at the rear along with a large hydraulic winch should balance it all up. I've worked out which gearing to go with as well... 255/100r16 tyres, 1.222:1 Transfer case, and 3.54 diffs should give me 124kph at 2500rpm.
Any more progress on yours? Must be nearly ready to drive...???
