Monster 6 Turbo Diesel into a 101.

If your current engine is running hot I would say that you might have an issue with your current cooling system as mine runs spot on. I do not have a viscous coupling on my fan and it is not particularly noisy even when the engine is well up the rev range so with your max around 3500rpm you shouldn't have too much noise from the fan.

One small mod that my 101 has got that you might want to consider is fluting the body work either side of the engine - in particular the removable access panels. This does help the flow of air through the engine bay and no doubt helps with cooling a bit.

Now, having driven my 101 for nearly 500 km, one thing I've noticed is that they like to run warm over here.... so with this in mind, a few days ago I've bought a Dodge Ram fan hub and pulley out of the states, which which will bolt onto the front of the block and put the fan roughly where it sits with the current V8. I'm going to use the original truck fan that came with the engine as its in great condition and HUGE!!! By doing away with the viscous coupling, I can keep it close to the engine and even closer to the rad which will mean minimal cowling. Overkill...? Probably, but its better with more than less, and as the engine is flat out at 2800/3200, it won't be that noisy.... and if it is, great! You'll hear me coming!

Its Nick Steggel's truck that got me started on the 6Bt's... I'm now in contact with him, Ash and Tom, the three Cummins fella's in the UK. There's also a vid called Cummins Land Rover by 'Mr2Jags' which has a great note inside the cab when he stretches its legs up the hill! I was originally looking for another Nissan Fd6 out of a UD truck, as I'd done it before, but once I'd heard and seen the Cummins and looked into it, the engine and box combo seemed to be ideal, and cheep out of the UK....

Garry, I've already removed the two side panels, in an effort to help with the cooling. I've not been game enough to let it get hot, but it will happily sit between the 85deg mark and that little red line.. which seemed high, but guess its not really.. I tested the thermostat out of the Cummins and it opens at 90 deg, so the gauge will be up near that red line with the diesel.... I'm also going to get a deeper core put in the 101's radiator to help.... No doubt the Melrose trip will test it out!!

Amazing, Im planning on trying to duct more air in thru the rad and intercooler area, and hope to have a 50mm shroud around the fan. I'll see how much room there is once its sat in there! :)

your 101 is so cool :D

Nice work.

The gear linkage is close but it does clear everything by 5mm, and the lever should sit on the flat area between the original lever hole and the RH edge of the engine cover..... Still not 100% sure if that turbo is big enough!!! :D

Heat wrap and a turbo jacket will help even more...

Yeah, I'd thought about that, but as its a big old turbo, I thought it might be better running with some air around it.. If it was water cooled unit I'd have gone down that route.. Cheers tho. :)

So when do we see it going in?

Yesterday was to be V8 removal, but I had to work, so it'll prob be the coming weekend.. Still waiting on the adapted gear b4 I can put the transfer case together, and then it'll go in as one. :)

Water cooling of turbos is only for hot-shutdown. When running the oil does all the cooling. There is nothing to fear with jacketing the exhaust housing and manifolds, but you want to keep the compressor side open to air.

What plan did you decide on for the input shaft?
