Hi, I've been looking at a RWD conversion using a Pug/citroen 1.9 XUD turbo diesel engine mated to an LDV pilot RWD LT77 gearbox.
I managed to get hold of a decent box and engine mounts from an LDV a while ago. Now i'm looking into getting the additional parts to complete the conversion. I did have a link in my favorites for such a list, but it has been deleted unfortunately!
So can anyone help?
I think such a conversion requires the LDV flywheel/clutch, and the clutch is hydraulic operated as far as I know, I have a Rover V8/LT77 cluch cylinder, could I use that? Anything else?
Thanks!

Chairchild is your person - he got the engine and box together and working with a clutch, but I can't recall the details.

I managed to find a snippet of info that says I need to use a 306 HDi clutch/Flywheel kit, which are easily available. I just need to sort the hydraulic clutch now I hope. Cheers for the headsup on charichild will try to find him!

any RWD XUD conversion will always get my attention lol I used a 2.1 XUD (all XUD and XU engines have the same bellhousing pattern) You need to find yourself a DAF dealership, and get the spigot bearing for the LDV Pilot 1.9XUD to fit into the end of the crank Fit the HDi flywheel + pressure plate, along with a ford galaxy friction plate (this is the correct size, and has the correct centre spline) The flywheel pickup sensor for the rev-counter, will now be virtually useless however, as it will now have vastly more than the original 4 slots to pick up (something along the lines of 40 -2, or equally daft) The gearbox is designed to hold the engine at the required angle too - but you may find the internal baffles on the sump are mostly useless,and you'll end up with no oil pressure under hard acceleration! I forget which engine it was - but there's a petrol (XU) engine that comes with a steel sump- meaning it's easy to cut apart, and make it more suitable for RWD use (avoiding a crossmember for instance) If you're running short on space for the vacuum pump, you can simply unbolt it, and blank it off with a sheet of ally - then run an early 205 remote vacuum pump, which is powered via the fanbelt

Hey, I've got the box, hdi flywheel/clutch, new throw arm and rod so far.
What clutch slave did u use? I have one from an lt77 that was on a rover v8. Alsi what clutch release bearing did you use?
Was hoping to modify the crossmember rather than mess with the sump unless i have to. Its going in an mgb so planning to use the gearbox xmember i already have. I also have the ldv engine mounts but havent got a test block to trial fit at the moment. don't think ill need a vaccum pump, no servo. unless i need it to run the engine?
Have you used a low pressure lift pump at the tank? Will be searching for a bosch-pumped engine soon.
Thanks

I used the slave cylinder that was already on the scimitar it was going into - but it's a pretty generic cylinder that's nice and common. Release bearing was the standard Pilot jobbie If you've got the Pilot engine mounts (two massive castings,one for each side) than you're laughing! Will make your life SO much easier. They should be a direct fit onto a 1.9 Servo's only for the brake servo, and some vacuum accessories (EGR valves, VNT control, etc) And nope, just a plain feed from the tank, with a filter and priming bulb. A lift pump may help give the pump a longer life, and once you're above 180Bhp, it can give a slight improvement.... but generally not needed And tbh, just slap a lucas pumped engine in for now- swapping to a bosch is relatively simple once you've got the parts

Sweet, the ldv engine mounts are huge and heavy, but pretty beefy! I reckon they could be made a bit lighter tho. I think the next thing for me to do is get a scrap block and sump for clearance and try to figure the engine mounts out.
Guess I can forgo the vac pump then, and the lift pump. Do I need to fit a fuel return line? I have already fitted a late-spec fuel sender unit to the MGB tank which has a fuel return connection already ;-)
And I'm a bit worried about the sump/oil flow now ... what have you done for yours? Kinda hard finding an xud steel sump, you can get nice baffled ones for the mi16/gti engines but they don't fit!

Awesome cheers! I was wondering, I was looking at xud engines on goodle etc last night to ge the general feel of them, and I've a snealy suspicion the oil filter may get in the way of the chassis rails, in which case I'd need a remote filter ... damn!

If you get one with an oil/water heat exchanger (oil cooler) that's fitted under the oil filter - it can just be removed to give you a good inch or two of extra space.
This should only be considered a temporary measure though, to get it in and running - until you can get your hands on a remote fitting kit (if it's even needed)
Don't forget - the engines are tilted at quite an angle - you may find the filter will be closely related to the line of the sump anyway (it does annoyingly mean it ends up rather wide!)

Fit the HDi flywheel + pressure plate, along with a ford galaxy friction plate (this is the correct size, and has the correct centre spline) Can I ask why the HDi flywheel and not the XUD one? I'm sure there's a good reason for it, just asking as I mentioned the HDi/galaxy info to a friend who has a 306td and he wondered why. He said it's common for people running HDi engines to swap to XUD clutches. I'm putting an XUD + LDV box into my kit car at the moment. Pilot spigot bearing turned up in the post the other day, nearly finished making engine mounts and then I need to sort out a flywheel & clutch etc. Thanks for the info btw, great thread!

the normal XUD flywheel is a "pull to release" style clutch. I only realised this after fitting a XUD clutch (removed the release bearing) and wondered why I couldn't get it to release....... A HDi clutch is a "normal" style clutch - they're just not as strong as a XUD type, hence why people usually want to change their HDi clutch to an older XUD type The ford clutch is only needed, as it has the correct splines for the LDV gearbox And get a build thread up! Or at least some pics lol

Is it possible to put the xud turbo and manifold onto a 1.9 pilot engine and box ? Got a ford pop with a 2.8 v6 in that is giving me no end of grief so thought about the pilot engine and box as i canget one cheap but normally aspirated xud i really don't fancy much at all Any ideas or helpful advice is good ,, I fancy something i can run on veggie that way i could end up with a hotrod that costs next to nothing to run and can be parked up for months at a time without the fuel going off and carb being ruined etc ,quite torquey in turbo form and veggie friendly and decent gearing could mean running costs the equivalent of 100mpg with no mot or tax to worry about either no room in the engine bay for a canted over xud hence the upright ldv option

The only issue I can see is the angle of the oil drain but I'm sure you can get around that easily expecially if your modding the sump already.

This is the conversion I'm seriously thinking about doing to my 1971 Hillman Avenger. I've got the gearbox and mounts and have 2x XUD9T engines, both with Lucus pumps (unfortunately). I'll need to get a gear lever and propshaft at some point as they didn't come with the box.
Thank you chairchild for sharing your knowledge, much appreciated.
Will

Its a common conversion in the 4x4 world for Vitara's, it was so popular The Suzuki commercial Vitara is factory fitted with an XUD, I think its a different bell housing from memory? Shropshire Suzuki and the Suzuki section on Difflock .com would be good places to ask.

It will come in handy even if you never use it
