Good afternoon,

Please could I ask for advice re gearbox swaps. My son and I are building a project car and we hope to use the 3.0l V6 (AJ30) engine as the power plant. Our problem is we need it in a transverse 2WD configuration. I believe all the X-Types were 4WD and the S-Type is of course longitudinally mounted.

I have a number of questions to which I would welcome some enlightenment.

1. How would the X-Type 4WD box behave if the rear drive was disconnected? Would all the torque go to the front axle or does the diff limit the split.

2. What other gearboxes bolt straight on to the AJ30. The Ford box from either the 2.5 or 3.0 derivatives of the AJ30 maybe? I'm not sure how different the flywheel/clutch/bolt pattern and everything else is between these engines. Probably a bit naive to expect them to bolt straight on.

3. If I were to use an engine which has an auto box how would the ECU react to a manual substitute. Perhaps the same question with the X-type if you lose the 4WD box. Is there any ECU to gearbox handshaking?

Any advice would really be appreciated. When you open the bonnet on the car I really want it to say Jaguar in big letters rather than Ford or something Japanese!

Thank you.

 

Depending on the market, some later X400s were available as FWD.

I don't believe the AWD gearbox/viscous coupling are going to function correctly if the rear differential is removed from the driveline.

What you're asking is purely speculative on everyone's part since this is a modification that is unusual. Trial and error may be what's needed to find a gearbox, flywheel and clutch assembly that may work. In addition, the PCM and TCM communication must be mimicked somehow.

 

Fwd Lincoln LS maybe would be easier to find.

 

The 2.1 litre X-Type has a front wheel drive, 2 wheel drive, engine and transmission.

 

Thanks for the prompt replies. I had overlooked the 2.1 v6 until I read one of the related threads below and then your reply came through as well. For some reason I thought it was a different base engine.
So just to confirm the 2.1 and 3.0 have the same the bottom end? So that should be a straight bolt on in place of the 4WD box? And as mentioned earlier, if we widen the net a little, it should be the same story with the Fords?
Something else I read was about a one off supercharged x400 which is now in the Jaguar and Daimler Heritage museum which used a Volvo gearbox, albeit a 4wd box. I thought if I could identify the gearbox and see which Volvo model it comes from there must be an equivalent 2WD version. Although thinking about it as I'm writing I reckon the 2.1 route sounds like a much easier one if it is compatible.

Thanks again for the responses.

 

The 2.2d x type is front wheel drive and uses a six speed mmt-6 gearbox.
As this box is designed for 500Nm torque, and was used on various ford and Volvo diesels, it would be a good contender.

Thanks M.O.T.H . (Is it meant to come out like that?)

The diesel box would certainly have the muscles but probably not the ratios..? Would it be geared quite tall? And with the 2.2 being a 4 pot would it fit? I actually have a dead Volvo S40 diesel on my drive which could possibly have the same box but I don't really fancy taking it off just to have a look...but then again it could save me money.

If anyone out has the right experience I could really do with a definitive "Yes this one will fit a 3.0 V6"

Thanks,
