Reinventing an icon..

Swallows Racing has always been at the forefront of reinventing the wheel so to speak developing the power hungry AJ16 engine, developing the manual conversion to the S-Type R and now making the drivers Jaguar even better with manual conversions for the X150 body shell.

The X150 has been the greatest of a generation and what’s not to love, from stunning looks to powerful engines and handling its the ultimate mix of all 3 however as driving purists would agree it is missing the all important ingredient.. a manual gearbox.

We are currently developing this on our test bed Palmer sport XKR and are very close to being able to make this into a package for road cars, as well as custom flywheels and clutch the ZF 6 speed manual gearbox gives a beautifully smooth power delivery and due to the very nature of a manual box does not give any transmission losses unlike the auto ZF which looses roughly 50bhp.

The basis for this recipe has been used by Aston Martin for years across the range and unfortunately when the X150 body style was released we were not given this option, The ZF 6 speed box coupled to the V8 gives a more organic feel to the driving experience while the ability to unleash all the power in the lower rev range means its even harder to loose your licence. A raw mechanical feel coupled with a guttural exhaust note and surge is the ultimate drivers package and options that all R models should have been available with in our opinion.

In order to keep the conversion as high quality as possible the pedal assembly is genuine Jaguar components which keep a factory feel and the shifter kept in the same J-gate recess, the pedal feel is firm giving a sense of meaningful throw to it and the 6 speed box flows through the gears seamlessly. It was very important to us that the prestige of the marque kept its character and build quality throughout this project making at a true contender for best GT cars.

We have been working tirelessly over the last few months to get this package right for the X150 body and are currently on the final step of getting the shifter ergonomics in place in order to keep the natural factory centre console look and feel, the clutch compound options also give you a more tailored feel to the package from everyday driving to race. Keep your eyes peeled over the next few months as we complete this last step and extensively test the package on the Palmer sport XKR on and off the track ready for orders.

If you would like any further information on our manual conversion packages for the X100 and X150, give us a call and see how we can make your pride and joy a more engaging drive.

    Hi, I’m enquring into how development of this conversion is going since the article was posted… I am slowly collecting parts for an STR and would like to know how you are spoofing the TCU and costs involved. Regards

    Would dearly love a 2003 – 2005 XJR or 2006-2009 XKR manual using 6 speed S type box . A flywheel and reprogrammed ecu for manual box seem to be the issues??! Thanks. Digs

    Hi
    Do you do a manual gearbox conversion for the x308 4.0L supercharged model?

    Me and a friend have just sold our old track car and are looking for somthing a bit different.

    Any information on the swap would be great.

    Thank you

    Hello Swallows Team
    My Name is Nico. I saw in a post that you guys are developing a manual conversion for the X150 Jag XKR. I was wondering what the current status of the project is. Im interestet in the project because i think that a manual XKR would be the perfect car. Could you give me an update?

    Regards Nico

    Hello
    Hi Guys, recently seen you’re gearbox conversion work on the s-type r and drivetribe XKR.
    It was my plan 2 years ago to do this on my 4.2 XKR but found out that Tom Lenthal could only do it on a 4.0 at the time, so just had a Quaife LSD and poli bushes fitted and hoped someone else would come up with the ecu CAN BUS problems.
    so it seems you’re selves and PVE have solved this problem now.
    So I’d like to know how much this will cost please as my car really needs a manual box to make the most of the other work.

    Thanks.

    Gary.

    Hello from France guys ! I’m currently restoring a 2001 4.0L V8 and found your concept really attractive. Have you ever done this kind of work on a phase 1 S-Type ? Do you think it’s possible ?
    Thansk a lot for the great workj 🙂

    Hi,
    Having owned a few Jaguars over the years, including a 2010 XFR, the one bit I felt was always missing, a manual gearbox option.
    Watching the recent Drivetribe video, I am very interested in the estimated cost of converting an XKR to manual, with uprated suspension and brake packages.
    Many thanks
    Ian

    Hello,

    Like many other comments on this article, I am interested in the cost/ lead time for 4.2 XKR conversion. 🙌🏻 I hope you have made progress on this package offering.

    I look forward to your reply.

    Good morning!please understand that I am looking for upgrades to make my 5L XKR as fast as possible in a straight line while maintaining its comfort for long distance traveling. I mentioned wanting racing wheels and potentially having the heads ported, removing the head gasket, and installing new piston rings. a comprehensive list of upgrades that can enhance my car’s acceleration and top speed. I understand that these modifications will require professional installation and who better than you?

    1. Racing Wheels: Upgrading to lightweight racing wheels can reduce rotational mass and improve acceleration.

    2. Engine Tuning: Consider getting a professional engine tune-up to optimize the engine’s performance. This may involve adjusting the air-fuel mixture, ignition timing, and other parameters.

    3. Cold

    Good Afternoon,

    Like so many others, I’m enquiring about the cost of your manual gearbox conversion for my late 2003 4.2 XKR? I already have a 2.7 diesel manual S type ‘box, so it’s the cost of the conversion kit I was enquiring about.

    Many thanks

    Hello Swallows,
    I have a 2002 4.0 XKR and I’m considering a manual swap. Do you have any news on cost or availability of a conversion kit? Or even the odds and ends like pedal box, flywheel etc.?
    Thanks,
    Tom

    Hello, I too am interested in converting my XK8 to manual. Please let me know if the kit is available and, if so, how much it would cost. Regards Andrew

    Interested for both a 2007 and a 2010 XKR… Send information please on the Kit and Cost. These cars would be awesome with manual transmissions. Don’t understand why Jaguar never made a manual version, it would have definitely helped out with greater sales!
