LS Swap X150

You’re comparing pineapples to cabbages. The X150 can do better than 4 seconds with minimal modification. The issue’s the complex modern electrics which are integrated with everything. A Coyote or LS swap is not as simple as dropping it in with a few simple fitment modifications as you could with a vintage car, you’ve got the PCM and canbus to contend with.

I know the electronics is what most people do not realize, I have done it on my 63' Jag with a LS1. Sure every person has their brand favorite from Ford, Jag, and other V8's but why the GM LS V8's are so prevalent is that there are so many aftermarket options to make the electronics way easier. An LS V8 has multiple companies making most every part you need for a swap and so many can tune the factory ECU to your car's needs so it makes the difficult process way more manageable. Yes if you want to keep it all Jag and use a modern Jag V8, the electronics will be difficult, but an LS is way easier and there are not only so many options but you can find so many tuners that can tune it for you and your specific needs.
I not only have an LS1 restomod classic but in 5 years I have over 200,000 daily driven street miles clocked. A restomod classic will always turn more heads and for me is a joy to drive daily and not worrying about racking the miles as it is affordable to rebuild them or upgrade to new. While this looks to be an expensive V8 swap the performance of this sleeper XK150 is pretty cool https://www.facebook.com/watch/?v=10150592933417503

Yes a microwave oven, 3000 watt sine wave inverter, color lazar jet printer, and I've added a scanner enables the Jag to be a mobile office work horse M-F and on the weekend the quick release removes the RAM mount laptop and the hidden Focal & JL Audio subwoofer sound system makes it an ideal street car, plus front/rear cameras, AC, electronic seats, wifi, hands free phone, and more than all of the electronic toys a new car has...

Uhhh, I just realised your confusion, because of the thread title...
This is the X150 forum, XK's & XKR's built from 2006-2014, with two-dozen computers in them and electric everything...
This is not the XK150 forum, as in the XK150 from the 1950's with a half-dozen wires and a few fuses.

- Actually the ECU is not as much of an issue as you may think. Motec have one which is suitable to both the 4.2 and the 5.0. The challenge is the TCU on the 6HP26 transmission. There’s been some R&D on interfaces, but it’s not all there yet. As for the rest of the electrics, we’ll yes there’s no solution for that other than ripping it all out. I agree with Cambo though, I had a thought that perhaps he was thinking of the XK150.

Jaguar also did one hell of a job getting more than 500 HP out of a tiny V8 without reducing reliability (much).

they used a supercharger to get 510hp ,,the NA Jag 5.0 is only 385hp
by comparison the NA 5.0 in the Mustang makes 460hp without a supercharger. Models like
the Roush Mustang with a supercharger similiar to ours make 700hp and still has factory warranty.
Both 5.0s came out at about the same time (2010) .
The fact our 5.0 was made in a Ford factory makes it even more confusing!

Your talking about x150 as in your profile you have a xkr (so it was correctly titled in the thread, it was just primaz that got confused)
The xk150 is the vintage car in the photo

Yes and no..5litre V8 is not tiny in todays world.

With all that good gear in there with aftermarket headers and a tune surely it would have to get close to 450bhp .

To summarize for future readers as this question's brought up frequently on these forums, like most if not all "modern" cars, since the advent of networks like CANbus, integration of electrics and modules and mechanics is rarely "open" architecture, if keeping it "stock" and the intent's simply swapping out the engine with a different make, good luck or have a massive budget. If gutting the car and replacing EVERYTHING with custom, can be done, but still a massive budget needed. If more power's the only goal, that's easier than some might think. You can achieve over 500HP with the 4.2 and simple modifications, perhaps more power with more extensive modifications (it's been done). If you've a 5.0 litre, then the power increase ratio's even more in your favour. Jaguar's done over 600HP in house and other's have done over 700. If that's not enough, then you ought to consider something else as the X150 platform is not really conducive to that, IMHO...
