Thread: 2.5lt diesel

the tdi200 will pretty much drop straight in. I wouldnt want the turbo on it if your keeping stock sereis running gear.

I think the tdi300 goes close but need some minor fiddling to make work.

2.5Ds never came to OZ - but that doesn't make them more valuable. If it were me, I would try to find a 200Tdi instead. Should be able to pick a good one up for less than that (you can get a whole disco with onje fitted for less).

Not sure what you mean?

A 2.25, 2.5, and 200Tdi will all bolt straight onto a series gearbox. The 2.5/200Tdi need you to relocate or raise the battery to clear the timing/injector pump assembly though, and I think for the Tdi there is one stud you need to remove or drill a hole for to get the bellhousing to bolt up. If you use a disco 200Tdi there is also some complicated plumbing to get the turbo dump pipe to clear the footwell.

If you fit a 200Tdi to a series box, you need to have a gentle right root (unless you remove the turbo as some have done). You can fit the LT77S box which came with the engine, but that is no longer a bolt in proposition. If you do that you need to either (1) buy an LT77 to series T-case adaptor from ashcroft, or (2) fit the LT230 t-case.

Option (1) gives you a drivetrain that is 4" longer, and option 2 is similar, so either way, you will need to at a minimum move the engine mounts and radiator support - and maybe also change propshaft lengths.

Just a thought, The 6cyl transmission is mounted 4 inches further back than a four. Would the 200Tdi/R380/LT230 go better into a 6cyl chassis than a 4cyl? I know you'd still have to modify the firewall and battery carrier...
