Jaguars with LS1/LSx Power

[the-jag-guy]

Hi all-

This is Andrew from Jaguar Specialties (www.JaguarSpecialties.com) and I thought you might find some of our latest projects interesting. Specifically that is LS1/LSx power for Jaguar 70-87 XJ6/XJ6C and all 76-92 XJS cars. Jaguars have been converted to Chevy power for years, but there are only a handful of LS powered cars running around, all very tediously (and expensively) hand built. We wanted to do the conversion so that any Jaguar owner with a reasonable budget could also do it, and not have it cost an arm and a leg. So now, after a lot of effort, we have running LS1 Jags to show the concept works and the overall cost has remained very realistic. As part of the development, 2 cars were built side by side- one is a 75 XJ6C (a 2 door coupe version of the XJ6L sedan), and the other an 89 XJS convertible. In the end, the fit of the LS1 packages in both cars is very good with adequate clearance all around. The initial test drives of the XJS surprised even me with the power and torque (and the likely power potential) of the LS1 (and this in a 3700lb car with a 2.88 rearend ratio). Keep in mind my daily driver is an 88 XJSC T-top powered by a 97 Camaro SS LT1 and 6 speed, so I know what good power feels like. Anyway, we're very happy with the conversions, and feel they were well worth the effort. All of the details and experience from these cars has been packaged into a new kit (parts and manual) to allow customers to do these conversions as well.

Here are a few pics of the two engine installs- the first one is the XJS at 95% completion, running and driving. The second photo is the XJSC at about 75%. In both you can see there is good clearance all around (and both cars use OE GM exhaust manifolds- not custom headers....). I expect the conversions to be very reliable as they use an overwhelming majority of standard GM parts, and a minimum of "custom" pieces. Have a look and see what you think...

I'll have to check out your site later, I just purchased an '85 XJS myself. No plans for any modifications at this point but you never know

Looks good. A manual transmission Jaguar would be fun

Did you have a question or ???

more pics of the XJS conversion please!
this is something I hope to do eventually

Thanks for checking out the post.

What you see there is really all there is to see. Aside from under the hood, the car itself looks stock . The interior remains as it was originally, all gauges work as original, as does the shifter. All of the accessory drive is stock GM- no compressor relocation or anything like that. And stock GM exhaust manifolds work as well- very simple and effective...

I've put a few miles on the car since that first post, and the conversion is great. The LS engine is so much more smooth and torquey than even the 97 LT1 I have in another XJS. Hard to believe.

The results of this project are now available in kit form for anyone in doing such a conversion. For more info, Email me.....

Very cool!

My mums old cruiser was a series 3 Daimler with a 6.2 Chev Diesel and T700 behind it. You can imagine how much nicer the wallet felt after not having to fuel up the v12!
