I only mentioned the 6bt because I have one sitting in the shed for my 61 f100 unibody project. Also 6bt have been successfully fitted to a number of defenders, one of which was a 90!!!

How much does a 6bt weigh?

1100lbs, I think that converts to anout 500 kg. To give you an idea I believe a 351 Cleveland ( the other motor I have for my f100) is about 350kg

IIRC the 4BT and 4BD1T are around the 400-425kg mark, and a Tdi roughly 250-270kg ??

Dougal has posted up weights of the 4BD1T and 4BT somewhere, hell I think I may have posted weights comparing the Tdi to the 4BD1.

hahaha, good luck with that. Obviously you dont subscribe to Colin Chapman's theory of "adding lightness"

Im sure it will improve braking though

It's the old way to "break" a record in a defender.

The old f truck has already had a substantial brake upgrade uninformed. I got the 6bt real cheap with an adapter to ford bell housing, flywheel and engine mounts to suit Cleveland base plates. I have not 100% made my mind up yet as to what engine to run. Leaning towards the cummins for fuel economy, geared right they should easily get 10l/ 100km.

Sorry to everyone else I realize this is o/t

whoops, I think ive entered the F Truck forum.....or is it related because at some point Ford owned LR

The 4bt is a great engine, but IMO its weight is an issue for LR...like I said IMO.

a 6bt, no bloody way! yes it can be done, yes it has been done, just like GMC V8 diesels etc, doesnt make it a great idea

each to their own

not something like a 6bt cummins...but something in say 500nm.

so a chipped td5 then?


theres a significant number of tdis and a couple of td5's that are pushing those Ks so the engines sound.
