Thread: R380 TD5 vs 300Tdi

I'm not sure about the bellhousings and input shafts, but I'm pretty sure the the TD5 R380's have a remote oil cooler where the TDi R380's don't

The oil cooler would be a benefit. I think that the earlier R380 can also have a cooler placed onto them. I believe that in the UK the plate to stick on the side of the R380 are plentifull for the earlier boxes due to the use of R380's behind V8's in Discos

This has been asked last year some time - the answer was no: the input shaft is a different part number. For the record, my use of a v8 r380 in a tdi wasn't a great success as the custom spigot bearing didn't last too long. Your right about the remote oil cooler, but you'll need different lines to clear the different shape bellhousing and exhaust pipes.

Just as a matter of curiosity, I heard that the last Td1300 1999 models have the coolers. It is that true?

No, not true, or at least mine never came with one.

What the last of the Tdi's have though is a 'K' suffix 'box, which has revised internals and is a lot stronger than the earlier 'J' suffix R380.

Dave Ashcroft has said that they treat the 'K' and later TD5 'L' 'boxes as the same when rebuilding, and are structurally the same although there are are a couple of small detail differences.

Some Tdi's came with oil coolers, eg UK Army Wolf's have a huge one in front of the radiator, and apparently some early African spec ones used them.
UK/European delivered TD5 Defender's didn't come with a g/box oil cooler either.

Thanks Rick, do you know if the cooler can be adapted to the 380GB circa 1994 or the plugs for the hoses are not there on the case?
Cheers

Yep, it's easy. On a non cooled box there is an oil transfer plate that bolts on to side of the box, just remove that and fit the t/stat/cooler line housing (using new O rings)

I'll look for some pics.

Yes, the housing and thermatic valve that bolts to the side of the gearbox is the same for LT77's and R380's.
