2000 XJ8 Manual Gearbox conversion - Flywheel ....?
Hi guys, new to this forum ( see other post) so please forgive me as I now this has been asked before.
I want to put a manual gearbox onto my V8. I have a Getrag MT82 which will handle the power just need help with the flywheel. I've read on hear that you can use one of a xj40 or other 6 cylinder engine but done know exactly which one. If that's the case does anyone know if the pickup for the ecu still works or do you need to sort something else, if so what.
I've found a company who do the adaptor plates or could make one myself as I've done similar things before so no real problem there. Obviously will need to fool the ecu somehow into believing the auto box is still there.
Why am I doing it I heare you ask, well why not it's a challenge for the winter nights in the workshop.
Look forward to any help anyone can offer.

Ian,
No replies in 36 hours so I've moved your question from General Tech Help to X308 forum and added some detail to the thread title to attract attention.
If anyone has the answer, members here with the same model are the ones who will know.

I do not think you can use a flywheel from a different vehicle, as they have holes in very specific places for the pickup sensor- even the V8 variants (AJ26/AJ27) have different flywheels, and are not interchangeable. Seems to me Telling the ECU not to look for Transmission inputs will be the challenge here.
I will look forward to your success though!

You will probably be best off having a flywheel assembled by a specialty shop. You'll need the bolt spacing specific to the crank, pilot bearing specific to the input shaft, ring gear specific to the starter, and surface area specific to the clutch. Further, until you know how the bellhousing will attach to the engine, you can't know how thick everything needs to be. Anybody who builds flywheels will be able to knock this thing out from billet aluminum and probably (hopefully?) use an OTS ring gear no issues. I think you'd save time and maybe even money going this route vs trying to adapt something.

I have a drawing of the flywheel (somewhere) I used on my XK..... Use the ring gear of the flexi plate, you can drill the spots out on the timing ring on the back and bolt this in or have it machined in........
I used a T56 on my XK but will use an S Type box on my XJ (if I decide to do it) as I have one and they bolt straight on....

Thanks that's good info. Did you manage to find the drawing. Ecu shouldn't be a problem as emerald do a stand alone ecu which they have the mapping for and can talk on the can bus to the other ecu's
I'm going to go with the adaptor plate idea first them do some measuring for the flywheel and probably get one made. Found a company near me in Leeds West Yorkshire thT can do it.

The S-Type's petrol V6 was a Ford Duratec, the same used in the Lincoln LS and... the Ford Taurus and... Contour/Mondeo. Definitely not the same as the AJ, and precisely the reason why the S-Type and Lincoln LS V6 were both available with a manual gearbox while the V8s were not. In the Jaguar applications (including the X-Type) they were thoughtfully called the AJV6, despite just being a Duratec with a fancy top end. The diesel V6 was a Peugeot/Ford joint effort. I'm still baffled that it shares a bellhousing pattern with the AJV8.
The F-Type's V6 is Jaguar's new V6 platform and doesn't share (to the best of my knowledge) any connection with the Duratec. I wouldn't be a bit surprised to find it sharing a bellhousing pattern shared with the new Ingenium four cylinder, as that'd be awfully helpful for the XE.
Edit: I lied. the V6 in the F-Type and the XE is still the Duratec/AJV6, at least according to Wikipedia.

That doesn't help the manual-behind-an-XJ at all.
Edit 2: Looks like the new F150 will have the "Lion" (AJD-V6) diesel, so maybe it'll come with a manual transmission. Hard to say where Ford will slot in a diesel to the F-series lineup. If it did, and if the AJD-V6 bellhousing is in fact the same as an AJV8, that could be source for manuals for this side of the world.
