Hi Grant
Yep, that the engine number.
The plugs are standard n9ys, with the standard socket size (same as my GT4). The distributor is an early Lucas opus with the ceramic disk (same as mk3 etype?)
Maybe the rail has been transplanted at some time?
Started designing the chassis today, 1/5 scale using wood so far when scaled up I will need 30 odd metres of the stuff for the whole car, and I still have a bit to go. But it looks quite rigid.
The pattern I am using is below. I intend to modify this design to fit the V12 Renault UN1 transaxle and mk3 Granada running gear, I have a friend in the metal business who can get me the CDS for the chassis but I will have to upgrade my MIG to a TIG so I am told.

I like the idea of a donor V12 jag, there have been a few wrecks selling on ebay recently - eyes always open!

I haven't been idle, I have spent the last few weeks collecting bits to make a car. Yesterday I picked up the Audi transaxle and all the ECUs to get the engine running. I have also been stripping down the V12 and getting 30 years of dirt off the various bits.
Today I made the gearbox adapter plate template out of 13mm MDF, it all fits together quite well. I need to get an Audi flywheel and clutch though. I also need to get the Audi/VW starter motor to fit, so there will be some work there to modify the V12, should be OK though.

hi Nick
Great to see it's coming along nicely.

see if you can get a gear reduction high touque starter, they are much smaller and it could be a big ask for a standard VW group one to turn over the V12 fast enough [ you might try the British starter comp.] they sell the for most cars inc. Ferrari, good luck with making it all fit, you are a much braver man than me.

Such a fascinating thread. Please keep us updated! It would be cool to see it to its end result.

Thanks Grant,
The starter and flywheel are a big concern. I am also trying to source stuff on the cheap. I did well with the Gearbox, I used http://www.goofbay.com/ and got a whole transaxle for £25! The guy had spelt it wrong Normally they sell for £150 ++
The engine btw is out of an XJS produced in December 1979, the Jaguar Classics are being V helpful!


I have also been thinking about carbs, there is a Linx XJS on ebay with 6 webers, but he wants £1500 and I would rather get the project off the ground. There is a US company that sells dual quad choke manifolds for the XJS, for a marine application but it is quite reasonable, and two 4 barrel holleys would be cool!

Thanks Paul. I will keep this thread going as long as the mods don't mind? (I guess its a little off topic for a Ferrari forum).
Today I need to sort my garage out, I have a lathe which takes up quite a lot of room so it needs to be moved so i can get the chassis laid out correctly and the Dino in the same room

I have ordered 50 metres of 38mm 1.5mm wall steel tube and 1m2 of 12mm aluminium plate (adapter plate) no going back now

Cheers
Nick

Really? Wow, like the old Chevy 348/409/427. Is the deck 90* to the bore, or is it canted like the old W-block Chevy?

XJ40 flywheel

Hi Chaps - a long shot but does anyone know the diameter of an XJ40 / XJ6 flywheel?
Cheers
Nick

sorry Nick
can't help with the flywheel size and also the aircon as i have just got an estimate for the Daytona rebuild and i am going for a lay down.

Quote:

That's alright! not to worry.

on the flywheel conundrum.. Do you think all jag flywheels use a similar pitch for the teeth on the starter ring gear? If so I have the original auto flywheel which has 170 teeth at 6.5 mm spacings. I know also that the xj40 3.6 has 101 teeth which would make a diameter of 20.6cm. Seems a tad small but at least I know it will fit in the bell housing! I also read that the XJ40 starter is a V high torque one so with some mods should fit. (I hope)
Cheers
Nick

Sorry still cant help, but you could try these sites as they have very good parts drawings for jags

Update 1st March 2008

This week I have carried on accumulating "bits". 2 x E-type jag engine mounts, Dizzy cap, 38mm milling hole cutters to make the 2 x 6 branch manifolds, aluminium plate for adapter, 150mm x 50 aluminium bar for the drive shaft adapters, drills, clutch plate and loads of stuff! The post man is loving delivering to my house!

The engine has been stripped down, all that is left is the block with its heads and cam covers, everything else has been taken off and sand blasted. So far the only thing wrong with the engine is one of the cooler pipes that runs the length of one bank has rusted through.

I have made the adapter plate from 13mm thick aluminium and the gearbox mounts up really nicely. I still have to tidy it up, but it’s on there and it fits" I have ordered an Audi quatro clutch pressure plate, starter and flywheel to mount to the jag lump. The flywheel will have to be machined by someone else as my lathe is not big enough. On the pic below you can see my MDF template hanging on the lathe

The Jaguar heritage have come back to me with details of my engine, it is out of a Dec 1979 XJS.

I have also managed to find a "give away" mk3 Granada, which will provide hubs, steering, electrics etc.. I have gone for the mk3 as it has disks all round and ABS.

Today I bought the donor car, a 1990 Ford Scorpio 3.0 Ghia Auto, picking it up tomorrow!
The chassis is coming along well, about a 1/3 finished, the audi flywheel has gone off to be modified to fit the V12 and I have a new heavy duty clutch to fit on its return.
I have bought myself a 12 tonne pipe bender to make the v12's headers and the curved part of the chassis (windscreen surrounds etc..) Its actually beginning to resemble a .....(not quite sure) but it looks meaningful anyway. The engine mounts nicely in its cradle.
The only real problem is the size of my garage, the Fezza is nearly hard up against one wall and the chassis the other. Today I had to move the freezer out to make enough room to make the drivers side of the cockpit.
So far I have used 30m of 1.5" steel tube, and the chassis is still amazingly light!
I got the Audi starter to fit the V12 but because the flywheel is a fair bit smaller than the jag one, a fair amount of cutting has to be done. With the starter hard up against the block I recon I am as close as I can get to spot on.

29th March 2008 - Update

The chassis is now finished! All that remains to do is weld the underside and go over all the welds properly to make sure they're good.
Last night I took the engine out and moved the chassis onto its side - MAN its light!
I have fabricated all the front suspension bits using transit track rod ends and Cortina ball joints. The drive shaft adapters are finished, basically its all coming together nicely.

By the end of next week it will have wheels on, and I should be able to start doing more interesting bits, like the engine, electrics etc... Last night I bought some carbs for the old V12, a pair of rover 3.5 SUs, i figure its got to be easier getting it running on those than messing around with the injection.

I have decided to go down the 4 barrel Holley route (probably) and use 3 of them in a row, cheaper than DCNF Webers and I recon easier to set up.

The gearbox/transaxle has its new flywheel fitted and clutch, I have still to make the spigot bearing, I have bought a bronze rod so will knock one up out of that.

I am still troubled with the starter; the Audi flywheel is MUCH smaller than the old jag's. I have cur away a lot of engine and can just get the Audi starter to line up with its flywheel, hopefully it will be a lot easier to "do" when i have wheels on the chassis and the whole thing is more mobile.

I am reusing the Granada's front all electric seats, I will obviously have to get them re-covered, but they fit nicely. When in the car, it feels right, although it has no wheels, doors, or body, if you sit in the drivers seat the car seems to wrap nicely around you, and look back over your shoulder at the expanse of V12 and it all seems worth while!

Next week the following bits should be coming. 6 metres of steel for the V12's exhaust manifolds, gearstick, carbs, and the final drive shaft. I didn't realise that Scorpio's have different length shafts, which meant I had to buy another one anyway grrrr...

I have managed to use just about every part of the Scorpio, even the tailgate's hinges and gas struts will be used to make the scissor doors, the electric windows are being reused, as is the whole wiring loom and dash (for the moment). I have bought a tool to remove the windscreen but I have no idea if I can get it out. I would like to use that too, although I would prefer a more curved one. - If anyone know where I can get a better windscreen please shout!

I hope you like the pictures and the update..

It's a great project, I'm full of admiration and look forward to seeing the finished article!


But I bet the neighbours love the donor car in the driveway........look Mummy, a pikey with a Ferrari

Looks like you certainly have been busy!

What happened to TIG welding?

It looks like you are using flux-core MIG.

I really feel sorry for them, they've just moved in
Hopefully the shell will be taken away next week once I have the final bits out of it.

Yep, my trusty MIG. I started using CO gas then tried the flux'd wire and it worked so well and its much cheaper! The welds seem neater as well.
I do need to find someone with a TIG for the wishbones though. Otherwise it won't get through the SVA.

Fantastic thread Nick, thanks for sharing so far

Thanks Rob!
If I ever finish this beast it will be a seriously quick car.
I have had the engine off the chassis today and did the final underneath welding. Also fitted the seats, and started working on the rear suspension. I also got a bag of rover 3.5 carbs off a guy on eBay try and fire up the old beast next week.
For the first time its all up on axle stands, next the wheels go on...

The 12 branch manifolds turned up today, flat packed basically 12 flanges and 6 metres of pipe.

The car is exactly the same dimensions as the C12 so things are hotting up
