Diesels, if given a choice

Say all else being equal, is the consensus to go with a Td5 over a 300 Tdi, or is there a legitimate concern with the Td5's electronics?

The TD5 was designed to address increasingly stringent EU emissions requirements. However, in parts of the world, the 300TDi continued in production and basically skipped the TD5. Israeli military continued using the 300TDi for maintenance reasons well into the 2000s. If there is a better engine to go with, it would be the South American 2.8 ltr diesel (I believe a ford variation of the 300TDi, with a lot more torque and a VNT). I had heard that they were out of production but that may be wrong as I understand that East Coast Rover is still installing new conversions. Used 300TDIs are still readily available from the UK.

A chipped and remapped Td5.

The TD5 has an ECU to control it. They are pretty reliable and well understood but would make for a much more complex retrofit.

The power and performance of a 300Tdi is similar to a TD5 and has the advantage that it can be run from a single hot wire from the battery in an emergency.

The military and others continued to use the Tdi for the field servicability concerns ..

If given the choice I would want the td5. The td5 is much more drivable.

Oh we're talking retro-fitting this puppy in the 90? Then 300 for the simplicity.

The Td5 can be a rocket ship, but the 300 is a simple beast. I'd want the Td5 for most of what I use the truck for, so it probably depends on what your intent is. If you're talking about something that can wade trough deep water, etc then I'd be inclined to choose the 300.

Correct me if I am wrong, but I believe the TD5 requires a specific transmission/bellhousing.

No retrofit and no interest in 4' deep water crossings. The Td5 is already installed on a D-110 that has been stateside for a few years. Also assuming the Td5 is better for hauling a car trailer?

The TD5 will have better road manners than the 300 and will also tow better than a stock 300.

that being said I would still go woth the 300 in terms of simplicity.

im running a 200

Trails and short trips I'd vote for the 300 for its simplicity. As a daily driver or for longer trips the td5 is mighty nice. You can listen to your music, talk on your phone and go up hills without downshifting

Td5 uses a timing chain where as the 200/300 Tdi uses a timing belt.

TD5 can be plugged in and read at your local Land Rover dealer too.

I don't know about the HS2.8 pump, but on the 300 you can, in a pinch, remove the solenoid plunger and drive with no wire.

I'm more about simplicity so I'd choose the 300Tdi.

I went through this exercies a few years back and decided on the 2.8.

The 2.8 It's build stronger than the 300 and comes with the highly sought after turbo. Yet just as simple to work on as the 300.

However, if you don't want to throw that kind of coin at it, and still looking for simplicity, the 300 is a mighty fine choice.

The TDV6 is pretty awesome. 254bhp, 520 Nm of torque at 2000 rpm. 24mpg. More torque than a GM LS1 at just off the tick. *drool*

IMHO It would make a killer rock crawler engine when paired up with large radius tires.

200 is the same deal. In my exerience the plunger typically sticks open so not closed so running isn't usually the issue, its shutting it down.

Russell you are welcome to come down and drive a td5 and a 300 and see what you think.

Cheers,
