Cummins 6BT Conversion

Looking at a conversion for the 110, however id really like a start-to-finish guide from someone who has done it before me so i can avoid costly mistakes.
I know that Nick Steggel and pressbrake on here have done it but i dont think Nick has been on for a while. Ive contacted pressbrake and await a response.
I really need help from more knowledgeable folk than me as while im pretty good mechanically, im worse than hopeless with fabrication/welding so really need help with gearbox adapter dimensions, gearbox/engine mount advice etc.
Any help greatly received

Lovely engines apart from numerous oil leaks, so it will be right at home!

chap in the 101 section has just started a build thread.

You've read the "big purple one" on here i take it?

Yea ive read Nicks build thread. Very impressive indeed. Ive tried contacting him but dont think hes been about for a while

There is a good thread in the Members Build section on LR4x4 about a guy that put one into his 110.

Thanks mate. I will probably eventually take you up on that.
Engine will be a 12v keeping electronics/electrics to a bare minimum. Holset 35 or 40 turbo. Larger injectors. P7100 pump. Looking for around 500BHP. Which im led to believe is actually quite conservative for these motors once you start playing with them..

600hp depending what performance parts. This replica is set to make a world record later this year but with the look of the original car in the 1920's but powered by the latest Cummins 6B.

The torque generated while at 500bhp will destroy a lr chassis and complete drivetrain including the xf 5 42 that comes with this engine on daf 45 version
So now you need to source a heavy auto box from state side and 14 bolt gm axles etc etc
Forget the lt 230 transfer box which is one of the best but not at 1000lb torque
The list goes on

Would totally agree, youre ****ing up a downpipe trying to put that much power (torque) through a standard defender.

Im collecting a Daf 45 this evening to start this conversion, so must have a look at the thread on LR 4X4!

@Pressbrake, be prepared for a mountain of questions in the coming months

Plan to use the LT230. H.A.T.E auto boxes so will be looking to uprate either the ZF or Dana 5 speeds. Dana 60 axles will eventually be sourced.

@pressbrake i sent you a message but dont think you have got it?

Pffft wimp! Get twin 80's on the rear and a 70 up front, as to the chassis I'd make up a new HD one for yourself so it doesn't get fooked!


My new chassis is a 6mm box section monster which will take the 454 and then the Detroi Diesel I have planned for it next year

Wanna keep it light :hysterically_laughi

You want light yet you're fitting a 6bt and a Dana axle not gonna happen


You'll have to upgrade front springs to super heavy HD or possibly twins too just to cope with the weight properly

I was being funny! Or maybe not lol

go the whole hog, see if you can beat mine in weight

Dont that would be possible with the Detroit in it!!

true but theres only going to be a 454 this year

Thats ok - mines got a 4.6 RV8 just now so im afraid im still lighter. You porker lol

No point skimping in steel if you're putting in a big engine that wont care

Very true! Heavy Metal!!!
