Re: Y61 4500EFI / Cummins 6BT swop
I can tell you that the TB42 with all ancilliaries is about 225kg. This includes flywheel, clutch, A/C pump, power steering pump and alternator, both manifolds and carburettor.
It has an alloy head, so will probably be a bit lighter than the TD42, but i wouldn't have expeceted nearly double.
For interest, i once did a conversion on a 1969 Lotus Europa. From an all-alloy Renault 16TS engine to a Toyota 4A twin-cam engine. The toyota engine had a steel block and an extra cam, yet it was 1kg lighter than the Renault.

Its not the red pants...
Its the engine !
If you zoom in very closely you can pick up that there might be an issue with the radiator-fitment potentially resulting in cooling issues.

Ponies... My word that thing kicks out tyrannosaurus rex's.....hahahahaha
Peter, that TD42 head alone is a monster. For one man to pick that up is no easy task, add the diesel pump and turbo into the equation, one can burst a foofie valve...

Ground clearance is significantly lower than acceptable, but some OME coils and he is good to go

Re: Y61 4500EFI / Cummins 6BT swop
Ok, since my last post i did a TD 42 swop, what a breeze, everything fits and works perfect, but it is a TD 42, there are many around and it was no challenge so i went and bought a Cummins 6BT anyway, stripped it and started the mods.
The sump will get proper baffles to sort out the angle problem, Komatsu use them in loaders and excavators, they handle good angles with a baffled sump.
I've ordered spring kits & a fuel pin to bump the RPM to a safe 3500, 4000 is max, but we won't go there yet.
The Turbo compressor and exhaust wheels needs to be changed for more high RPM boost, we will take it up slowly, this setup can do 1000nm and 550 hp, but i need consumption more than hP, we will tune it to 650nm and about 360 hp for now.
I managed to find a set of 3.5 ratio diffs, that should give me about 2000rpm at 120km/h in top gear on my 33" tyres, torque peak is at 1500 rpm, so it is ideal
I've started with the adaptor flanges, i will post some pics as the parts starts to come together
