With thanks to MrSpeedy and his hydraulic press, the hubs were pressed off the driveshafts. My hub adapter blanks were also delivered through the post. The present idea is to turn the hubs down and mount the adapters on the back face to make them into 5x5" pcd hubs. I've just picked up a donor differential from an old Jaguar S-type The tags on the back are 3.54 and P/L And with the back cover removed I't a Powerlock lsd unit, which is an almost direct swap into the Scimitar axle case. The only modification it requires is a hardened thrust block in the centre as the driveshafts sit against the differential centre in the Scimitar axle. The only other issue is shimming the diff carrier, so I sat both the original open diff and lsd units on a flat plat of steel with the ring gears removed to see what difference in offsets there was between the CROWNwheel flanges Luckily they appear to be within a few thou of eachother, so not worth trying to re-shim the bearings. The pinion needs to come out of the axle case so that will probably be adjusted to suit if necessary, just waiting for the axle case to get back from the grit-blasters....

Superb stuff. You are a hugely talented and skilled engineer. I'm looking forward to seeing the recording being put on here of its first test run. Great stuff.

Looking good! Do you know how to change the amount of lock in the Jag diff? I've go the 4HU Power lock in my TVR, but it stock and not adjusted to a car approx. half the weight of the donor. It makes for some very interesting moments, especially on gravel

Thanks for the comments It's been on my mind for such a long time to put a live axle under the back of a P6 and no-one else has done it yet, so I may as well do it myself! Looking good! Do you know how to change the amount of lock in the Jag diff? I've go the 4HU Power lock in my TVR, but it stock and not adjusted to a car approx. half the weight of the donor. It makes for some very interesting moments, especially on gravel You can re-stack the friction plates to give more or less friction. They are mixed internal spline and external tab, so you should be able to swap some of them round to put two or three identical plates together depending on how they've already been stacked. On the diff I fitted to this P6 it had two internally splined plates together, I was tempted to fit one of the tabbed plates between to get more lock but left it pending road testing.

I think its an inspired job uprating the drive line like that its something ive hoped to see being done
One thing i note with the axle fitment is that will the upper links be ok under compression load when launching on stickies just with it being a rod albeit relatively thick, it might become unstable and collapse which would be grossly disheartening in the least!

Very good point, something I haven't as of yet put much thought into. The current plan is to get the axle mounted using the original suspension arms and mounting points, simply making it a bolt in swap into a standard car, then look at the existing suspension arms and uprating/replacing in the future. I know the boot floor mounts are a weak point and are likely to tear themselves out entirely, and on my other P6 I boxed them in. I want to avoid doing any modifications to the shell, and drill as few holes into it as possible, keep well within the vehicle identity system I also hope more people start taking an interest in these old barges and doing some serious engineering to them. Maybe somebody will be inspired and get building...

90% of the wagons on this forum fall foul of the 'unmodified body/chassis', adding extra strength where needed in a modified car seems sensible.
Great project & engineering skills!

Yep, my other P6 falls well into the 90%! It's a challenge as much as anything, cutting up the shell is lazy, so adapting what I get my hands on to fit is far more of a challenge. Obviously some parts will require strengthening, if I can get the whole car in an almost finished driveable state then adding more strength in the critical areas is the neatest solution I can think of. I had something a little special lying around..... I think I should

Using the original electronic pump for parts and practicing taking the pump apart, I got the pump elements out of it, which are 6mm internal diameter against the earlier mechanical pump elements which are 5.5mm diameter. In theory swapping them over should give a small rise in power, downside is they are precision parts and require calibrating in the new pump body. I have decided to skip the calibration for now, instead I've got another pump which I intend to have professionally built with much larger fuel delivery elements once the Mercedes engine hits the road and I am ready for it. Swapping the elements is really fiddly, difficult and time consuming! The mechanical pump governer was opened up to see how it worked, then removed to get full access to the main pump body Then onto dismantling the main pump body The pump went back on and the engine started up again, this time puffed a bit of black smoke right from cold and revved better Doing my research it looked like the Holset would create far too much lag, and only having a n/a injection pump I don't have any control over off boost fueling. The solution is more air! Using a spare Eaton M62 supercharger, I made a simple bracket to hang it off the side to establish where it would fit, and obviously had to fire it up again! Doing some number crunching and testing with a boost gauge, the Eaton M62 didn't really seem to be big enough, so a quick upgrade to an Eaton M90 was in order! Much better! The Eaton M90 fits better as well as sounding better, so my thoughts began to wander onto mounting it onto a Land Rover gearbox. A solid flywheel from an 80's Mercedes 230 turned up locally, and was cleaned up and fitted Gearbox adapter next...

Holy curse word! 1st. I never realised how much like an overhead cam engine a mechanical fuel pump was. 2nd. Thats a big snail! 3rd Thats a nice combo you stuck together. What output would you expect there?? 300??

What output would you expect there?? 300?? The old Bosch inline pumps are big chunky beasts, and have a big complex governor on the back to ruin . I predict bhp will be somewhere in the region of 200-250 going by what I've done so far and general internet consensus of what the injection pump can produce with the 6mm pump elements. Goal will be somewhere around 350-400 with torque through the roof, the engine itself in theory should handle that power, and the combined turbo and supercharger should feed enough air for that. The only restriction I foresee is the injection pump which I have plans to send a spare off for professional modifications, and the rest of the drivetrain not coping!

Loving this, and loving your approach as always you talented git I'm still in the early stages of compounding my isuzu. I have an M45 for it but I reckon its too small (1.7 engine) (I had intended to get an M62) planning on parting with it? (Although, no cash right now.....) Really cant wait to see this rocking and learn from your experience
