110 Clutch Intercharge and engine overhaul question

[VA7ZD]

A question for the experts.
The scenario.
I am in the process of overhauling my new to me 300TDI and am ordering the parts. This engine will be replacing a 2.5 NA diesel in my 1985 110. It will be coupled to the original LT77 which I rebuilt last year.
The question.
1: If I order a clutch, pressure plate and thowout bearing kit, part #LR009366 for a 300TDI, will the clutch splines mate to the LT77 input shaft spline.
2: Should I order the same kit for a 130 instead of for the 110. ie. is it a heavy duty clutch?
3: In the Land Rover manual it does not specify whether the head bolts, main bearing cap bolts, and rod nuts should be lubricated prior to torqueing or should be dry. From past experience lubricated but I am not familiar with Land Rovers way of thinking.
Any help would be great.
This engine was in worse shape than I was lead to believe and is getting a major rebuild. .020 over pistons, .010 complete crank grind, and a new head as the former owner drilled out a broken glow plug and wandered into the head with the bit. My bad for not paying more attention. Such is life.
Thanks in advance

1) The clutches are all the same as are the splines and such. The throwout parts should be as for the LT77. Replace them all as everything wears out. Consider a metal case throwout bearing and a reinforced fork. IMO, change everything from the slave through to the pilot bearing.

2) A 130 uses a bit bigger clutch and that is what most people do.

3) Yes, lubed. ARP ultra-torque is a good choice.

Make sure you are using real OE branded or genuine parts....

I assume you know of other challenges with putting a 300TDI onto a short bellhousing gearbox as the engine is further back than LR intended?

Be careful if the gearbox is an early suffix as the extra torque is hard on the layshaft bearings.

Hi Red90
Please enlighten me as to the pitfalls of installing the 300. This 110 is an ex military, and it has the 2.5 diesel. I take it you are saying to use the 130 clutch and pressure plate. The transmission was completely gone thru, new bearings, syncos, oil pump and output shaft etc. While it was out I reinforced the fork. I also installed a new slave cyl.
Thanks

A stock 300TDI uses a long bellhousing R380. This puts the engine further forward in the engine bay. If you use the LT77, which has a shorter bellhousing, it complicates the exhaust routing as it is very tight. In addition, the intake and radiator plumbing will need to be all custom as the engine is not in a stock location. It is all possible, but adds a lot of complexity over installing things in a stock manner.

The problem with the early LT77s is the layshaft bearings are very small. The higher torque of a TDI can be too much for the smaller bearings. Depending on how you drive, they might last or you may only get a couple of years out of them. They increased the bearing size with the "F" suffix, which helps a lot. The "G" or "H" is even better and they seem to do okay with the torque of the TDI.

I will also add that if you have the stock 110, 2.5 NA gearing, you will run out of gears really fast with a TDI.

Yes to using a 130 clutch and pressure plate.
