Hi, not been on here in ages, been restoring the Range Rover body shell, nearly there now, so back on the oily bits ready for mockup, then the body will be off for blasting and thermal zinc spray coating. regarding the input shaft lengths, it's not a case of them not being long enough, but possibly just the wrong lengths! I'm not 100% until Saturday when I plan to have a proper measure up, but the sprinter dual mass delete flywheel I'm planning to use (used one before on a 606) adds a lot of length to the 606 and has a nice roller spigot bearing which pops out easily and is easy to change for a different spigot bearing. I have a v8 bellhousing, a tdi bellhousing, a tdi r380 and a v8 r380 to try combinations. Obviously if it were too short there's always the td5 r380 which is much longer input shaft and i need to buy one anyway if this looks like working as I need a suffix k or l box to build the strong one from! It looks to me that the tdi input shaft with v8 bellhousing will be very very close to working, but hard to tell exactly until all assembled. I suspect it will be a little short, which I hope I can remove from the faces of the bellhousing. We will see!

Yep. I have just bought a bosch m pump to convert the om606 to mechanical control. The pump to go for is from either the 3.0 or 3.5 litre turbo om603. Downside is they are rare in the uk. The w140 s class used the 3.5 turbo om603 for a while and they sold a fair few on the continent (but almost none in the uk). That's what the pump I have bought is from. The 12v om603 in that form was around 150hp and 310nm torque. The 24v om606 will make more on the same amount of fuel, and the pump has some extra margin on the stock plungers before it needs them changing. Should make a little over 200hp and 350nm on stock pump

Cool, thanks! Knew they looked the same but I'm rebuilding the rangey body on its own chassis while I get the disco chassis blasted, zinc sprayed and urethane coated so don't want to find something I didn't know about afterwards!

Just a quick double check, a Range Rover classic body is direct fit to a disco 1 chassis isn't it?

Will investigate that very soon! I'm pretty sure the long one will be ok. (That's using disco 1/ rrc soft dash gearbox crossmember) I had a very very rough measure and any further back will put the engine into the bulkhead. Will need a little unboltable section in scuttle part of bulkhead anyway to access oil filter lid, or remote filter but I'm going for the hatch! The bellhousing skirt on the om606 block is very short, doesn't have the adaptor like a tdi, and even allowing for the machined plate added in there will still sit closer than tdi would

On the om606 I fitted previously (different vehicle) I used a sprinter dual mass delete flywheel and sprinter clutch, with c220cdi 6 speed box. Don't want to go to the hassle of divorced transfer if I don't have to though. I'm not planning on much over 200hp which I'm guessing will be around 350nm of torque so the r380 should hack it ok if rebuilt. Re. Auto boxes I'm just not a big fan of them. Probably makes more sense to use one in many ways bug I just don't want one. I guess the other manual box options are the ML boxes and adapt the lt230 to suit (needs double ended splined shard making so not a cheap option once heat treated etc), or ssangyong bellhousing and Borg Warner t5 or tremec and divorced transfer. I think the R380 ought to work though and is less engineering and very well supported parts wise. (The company that machined most of its internals are only a few miles away from me in coventry!)

That was my thinking Carloz. I don't mind making my own adaptor but I don't want to reinvent the wheel when there are at least two available off the shelf, but both are for v8 bellhousings. I'm guessing it's more popular to be converting v8 auto vehicles but surely I'm not the only one changing a tdi for the om606?

Bringing this thread back up again, I'm just starting out on putting an om606 into a Range Rover classic. I'm going the R380 route, I don't want an auto. I'm aware of the R380 shortcomings but I'm not going for crazy power, it's a daily driver and I want to keep some economy. I see a few folks have used the SMT adaptor, I was looking at making my own if I can lay my hands on a drawing of the r380 bellhousing to save me drawing it myself. My first question is why do all the adapters seem to use the v8 bellhousing? Is this because it fits better than the 300tdi or is there some other reason? I ask as I have an r380 and lt230 from a disco 300tdi already (I was going 300tdi but can't bring myself to fit something so heavy with so little power!!)

An option for this type of thing is hot zinc spraying. It won't go inside the chassis but it can go on any surface that can be reached with a spray, and it is extremely durable. Sort of coating used on military vehicles and bridges etc where they are too big to be galvanised. There are a few companies in the uk that can carry out this type of work.
