@@markwillerton538 Mark love to know more about the bell housing / clutch mate up, have an '03 XKR. Just saw your video- obviously allot of research and work involved! Thanks!
Only recently realised these cars are auto only from the factory. What a disappointment that was! Glad to see the manual conversions out there. Delicious!
Your mods are fantastic! - I have an '04 XKR which I'd love to mod but in reality can't see myself having funds to do so without selling my house! lol. The stock car will have to do me...of course, these are beauties in themselves so I will have to remain thankful I was even able to buy a car of this nature in the first place. 👍
You have made the xkr I love . I have a xkr from 2000 and I need your knowledge to try the same transformation . Where finding the bell housing, the clutch, the pedal, etc... I only have Got a TREMEC T56! Thanks you
Hello. I got hold of the mechanical parts from a bloke who I was in regular contact with called Norman Durban. He had his own company called XKR transmissions. Unfortunately he died a couple of years ago. The other person involved is Tom Lenthal who runs his own garage in Surrey, UK - you can find him on the internet. I have done a lot of other work with him and believe that he may have taken over the conversion from Norman. It is not cheap though. The first time round, I used a so called black box to play the part of the transmission ECU so that the engine ECU etc. would not misbehave. After making a load of other mode to the engine, we finally installed an aftermarket ECU from Link. Very good but again, not cheap. It's all good fun though!
I bet you have fun with the ecu and TCM on this one. Well done! I'm working on a whipple 2.9 unit for the 4.2l setups along with full carbon induction all the way to the air trumpet. Wrapping up a set of long tube equal length headers as well. Have you had a chance to log your a/f at your boost level ? Curious where she is at WOT. Are you running stock injectors still or did you need to bump them up a little? Possibly the nicest setup I have come by. Certainly gets my engineering approval. Very tasteful. Regards,Derek Fricke
Wow, 2,9 - that's a beast! In my case, I can choose between two upper pulleys (3" and 2½"). At the moment, both suck in too much air above a certain point which causes issues with the ECU. During the winter, I am going to change the MAF sensor and readjust the lambda to the right setting. The injectors are stock for 4,2L but the pump and FPR are different. When things are set up properly with the new MAF sensor, I can post some A/F figures - either here or on jaguarforums.com.
Limited slip diff, manual box, clutch with servo, after market engine ECU, different air intake setup from filter to s/c, KenneBell s/c, Bermbo brakes, nylon bushes, straight through exhaust (only silencers at back) + hi flow cats, dials reworked, plus a few smaller things.
Amazing project, and I must say I was quite captivated by the cluster, very very nice! Was it a custom work for your car only or can it be acquired somewhere?
Thanks. Actually, I did it myself using a company in Leeds (UK) who printed the background to my spec. Swapping the speedo and rev dial was pretty easy. In hindsight, I may end up somehow adding a mode to the multi display to show show speed, just to make things easier! The gear and oil temp readout (the single digit on the water temp / fuel dial) is also a self made gadget. I could share the design but honestly, it would probably be easier to check with a local graphics company who can help you out - it is fiddly work but as long as you're careful to keep the scaling right (so the speed and rev readout are correct), it is pretty easy.
I understand. Thanks! Also, you mentioned that swapping the speedo and rev dial was easy, so they're not integrated, like a single unit behind the wood frame? If so, this indeed makes things A LOT easier and it's good to know about it! :D
Actually, they ARE integrated in a single unit. There is a stepper motor behind each needle. If I recall correctly, I simply swapped the 4 wires from the one dial and connected to the other and vice versa. This puts speedo on the left and rev dial in the middle. The think is that each dial seems to calibrate to the little black rest needle at startup. So you need to ensure that this is positioned correctly - but that is pretty easy if you are changing the dial background (i.e. speedo to left and rev dial to middle).
I see...so basically, the gauges are the same, just with a different background to comply with the readings they're getting; in your case, speedo on left, rev counter on the right...very neat!
Exactly! Well, the rev ctr is in the middle but I figure that is what you mean. You can try it out just for fun - and then connect things back again afterwards!
Hi Mark. Those are some beautiful modifications. I love it. I do have a question for you sir. I own a 2002 XKR In Canada. I'm looking to upgrade to brembo calipers. Will brembo calipers from a 2003 to 2006 car fit a 2002? And if they need some modifications what would it be? Thank you again and hope to hear back from you soon Mark.
Hi. In my case, they fitted inside the 18 inch rims. When I got the 2nd hand calipers, they were supplied with mounts that sit between the calipers and wheel hub. The mounts looked pretty standard to me so maybe that is simply the way Jaguar managed the change when going to the Brembos. By the way, I added spacers between the hub and the wheels. I think these are about 0,5 inch. The Brembos may have fitted without but I am doubtful, it was quite tight even with the spacers!
Hi Mark, do you still have the Xkr? What size of the Kenne Bell do you use? I have a Xkr 4.0 and also want to upgrade to a bigger super charger. So far I have only made some minor mods like sports exhaust and intake tube and air filter
Sure! I am using a KB 2,1L compressor. Be careful when doing any such mods though. I started out with a 4,0L engine which was working fine (I thought) with the new KB compressor. On a hard acceleration, there was a bump which I found some days later to be a blown top gasket. Actually, I thing it went on both sides. The cause was almost certainly pre-ignition caused by the excess air (i.e. lean mixture). In conclusion, if you upgrade the compressor, you MUST do whatever is necessary to get the fuel side right. Talk to Tom Lenthall in Basingstoke, he knows what is needed. Like everything, how far you want to go is a matter of money but again, be careful with this type of mod!
@@markwillerton538 Nice. Have you run it in the dyno to find out the power figures? I guess the 4.0 is a lot weaker than the 4.2 due to not having forged pistons and oil spray on underside of piston crowns, as well as weaker valve seats in the heads
@@higgins4042 Yes, actually. In addition to the upgraded compressor, I introduced a mod on the induction piping - based on parts from AVOS. The good news is that the air flows much better - up to 21psi with the 2½2 upper pulley. The bad news is that the MAF sensor hit the rail after about 50% power and to be honest, the car didn't really run well. My conclusion was that the engine ECU couldn't manage the setup (its ability to accommodate is a bit limited). So I had Tom L fit an aftermarket ECU. Wow, that did the job. Translated to the flywheel, the engine is on its way to 600BHP but tails off above 5000rpm to finish at about 550 to avoid pre-ignition. This can be solved by an improvement to the fule rail setup. Honestly, the last BHPs are not so important (the torque is there where it needs to be) - but I am thinking of possibly doing a further mod to allow the car to run on Ethanol. Let's see!
At the moment it is still the stand alone x100 ECU. The extra input pressure is an issue at WOT above 4500rpm (2,5" upper pulley) or 5500rpm (3,0" upper pulley). I am hoping to solve that this season.
Is a great transformation and I love it. The next step is to change the race clutch (pain in the ...) for a dual plate organic clutch from McLeod. Should be more driveable.
Wow.... Most tastefully modified XKR I've ever seen... please post more!

how much would it be to do this work. i cannot find much info online? is anyone in europe that can do this?
Please do a update on this build
will do!
How much did the manual conversion cost? I would love to do the same thing on my xkr 4.2
Stunning work!
Blower sounds great!
Kenne Bell!
Hello!
How did you « fool » the standard ECU to do the manual swap?
Thanks a lot for your help!
In the end, I change the engine controller to a Link G4+
Stunning car & gearbox
Thanks - now better than ever!

Changed the ECU in the end. Works 100000 times better now :-).

@@markwillerton538 What aftermarket ECU do you use? When fitting it, doesn't the cars standard ECU throw error messages on the dash?
Very nice but too loud, it would give me a headache.
Are you running a standard ecu or a stand alone?
At the moment it is still the stand alone x100 ECU. The extra input pressure is an issue at WOT above 4500rpm (2,5" upper pulley) or 5500rpm (3,0" upper pulley). I am hoping to solve that this season.
so ….how about some comments ? like to know what you think. as considering the same with mine.

Wow
That was dumb
