Converting and old TD to a 300tdi

I know this has been done before and there is lots of information out there with the glencoyne being the definitive guide for this (link)

With many thanks going to @RustyDefender I have a 300tdi engine to fit to my sons '88 110 (Thread link), and he couldn't be happier with his new engine.



The 300tdi was fitted to an LT77 and came with oil cooler, intercooler, and PAS pipes, once again cannot than rustydefender enough! However in his defender it had been fitted by moving and re-welding the engine mounts further back on the chassis. My plan is to use the Steve parker conversions mounts on the engine meaning I can use the original chassis mounts without the need to alter the chassis. Although steve parker have now gone out of business there is someone selling off their old stock on ebay and I managed to get the engine mount and conversion exhaust down pipe (link1 , link2).

My understanding is that by using this conversion RH engine mount and the original LH TD engine mount in the forward position on the 300tdi, the engine will bolt up to the LT77 and use the original chassis mounts. The conversion exhaust down pipe then allows the exhaust to miss the now forward LH engine mount and then bolt up to a stock 300tdi exhaust system (I know this used the rubber hangers rather than U-bolts but you can buy the bolt on brackets to convert). The 300tdi engine will then sit further back than usual so will need extended oil cooler, intercooler, radiator, and PAS pipes, but these all came with the engine.

Have I missed anything? Is there anything conversion wise that I am missing? I feels like, as @Knappster said on rustydefedner's original thread, I have won the lottery and this conversion is going to be very straight forward, which is giving me a feeling I am missing or overlooking something critical!

I know plenty of people do the conversion like you say, but I don't really understand it -

Why not mount the engine in the factory 300 position and just buy a cheap, stock, 300 exhaust etc?

I know the cowel etc all needs altering then, but you would be on stock parts into the future then, rather than custom consumables.

I'm sure there is a reason, I'm just not seeing it, hence the question?

It'll fit if it's a defender LT77, the disco one has a longer bellhousing (about 4inch longer)
I fitted Disco 300tdi and R380 to Defender then swapped the motor for a 200tdi later on.
Did one for my mate as well

It’s the defender lt77 currently sat behind the TD engine. So it should all line up.

The reason for me is I don’t want to have to cut and weld the chassis. The current chassis is beyond repair so will need a replacement as part of the rebuild. To do this legally it has to be a like for like replacement and I will be getting a glav replacement. Therefore I don’t want to cut and weld galv and defeat the point of buying a new galv chassis. By doing it this way it will just bolt into place. The extended pipes may not be stock but in my opinion are easier to source and less potential trouble with legalities than modifying the chassis.

My downpipe came down on top of my engine mount so had to modify it
