90 engine (200tdi) with LT77 into series 2-2a

is that a question or a statement?

samc88 · Nov 12, 2014

I think you can do it but would look odd as it would mean the transmission tunnel needs adapting and I think the gearbox crossmember needs moving. I think theres a few around with this conversion but not sure

Use a stubby bellhousing r380, lt230 and custom props. Your front diff would only have uj driveshafts not ideal for permanent 4wd. Can convert disco axles to take a leaf tho.

I've thought about this as well....

First, is it possible to put the series transfer box on the back of the LT77?

Secondly would the standard LT77 and transfer box mind if free wheeling hubs were on the front axle, set to disengaged, as I think even though still spinning, it would stop the extended wear of the UJ's in the hub. (Sort of the reverse of driving a Series with no FWH or FWH engaged in 2WD)

Thirdly, ignoring all the above, does this really wear out the UJ's all that rapidly in the front axle, if kept topped up and serviced? Has anyone long term tested this, or is it just what everyone thinks will happen?

For the original question, the engine fits, and I can fully understand wanting to put the matched gearbox in as well. Though I do like all the levers and "character" of a series box.

Look on Ashcroft Transmission site, they do detail a conversion. From memory it requires moving the engine forward 4"

The problem with UJ's is not wear, it's that the driven side doesn't rotate at the same speed as the drive side - it does in that 1 turn of one side results in 1 turn of the other side, but within that rotation the joint accelerates and slows down again. The bigger the angle (like steering) the more pronounced, which can put a wobbly feeling or vibration back through the transmission. Plenty have said it feels fine though. You could run free wheeling hubs if the transfer case has diff lock, i think ashcroft do a kit for 2wd/4wd selection too.

seen a couple in series 2-3 I know tunnels have to come from 90-110 my mate did this in his s3 v8 SWB mud plugger. v8 to 5speed nice but this was ages ago!!!!!

HEY HEY MAKE YOUR OWN POST!!

THIS IS MINE!! lol

:crutch:

ound:

don't worry mate glad we can join forces

it'll cost you though lol

I know that there's a kit so the R380 and LT77 even the LT85 and 95 transfer box can mate to these, there was a guy abroad who did this to a series 2 it was in LRO or LRM or LRW?
anyway was a BEAST of a thing, may have been a v8 or TDI of sort

See my question has helped

blue beasty · Nov 13, 2014

I don't get it myself, there's too much that doesn't quite work and too much fettling, especially as the LT77 isn't a massive improvement over a Series box aside from an extra gear.

There's plenty of bolt on/bolt off options for tuning a Series gearing to suit different engines and improving driveability.......or buy a Ninety

peter8315 · Nov 13, 2014

No i don't get it either, i bouhgt a series 2 swb with a 200tdi and 5 speed box, very poorly fitted and only half done, the rear prop was about 8 inches long, the bulkhead was chopped in two, they had used the disco cross member, no hand brake, i just took it all out and reverted back to a series box, i think it would be more feasable in a lwb, i think using disco diffs is a great combination with a 200tdi
