has anyone heard of someone put an xjr-6 engine from a 1995-97 in a series 3 Jaguar? How difficult would it be and where could u get an xjr6 engine, thanks

 

Someone has been trying to sell an XJR/6 engine for months now on Ebay.

Actually installing the engine would probably be the least of your worries. You'll need all the electronics and engine management equipment from a donor XJR, and that probably includes the 4L80E transmission which I think is fully integrated into the elctrical architecture....and which probably wouldn't fit under the car.

I'veheard of a fellow that installed an XJR/6 engine into an XJS and is was supposedly a very difficult swap.

Others will chime in

Doug is pretty much spot-on. Jaguar World had an article on the XJR-6 engine swap into an XJS and the electronics issues were pretty difficult. They did say, however, that Jaguar should have done that as a upgraded model.

why are you wanting to know??
Do you have a series III with a blown motor? In my opinion, the 4.2 series 3 engine is 80% of the joy of owning one of these cars.

 

The 4.2 lacks power though

 

true .. but as heavy as the series III is, if you're looking for speed you would be better off buying an xjr

 

The Ser III XJ6 and the XJR/6 weight virtually the same....right at 4100 pounds enpty. Of course the horsepower difference is quite large :-)

With age I've become a little lazy and have decided that if I want more performance its easier to just go out and buy a car that has the level of performance I want. Given that XJRs are so inexpensive on the market....well....you know where I'm going with this: same place Skanoski went :-)

Another choice is to find a Ser III V12. I have one in my garage now for some repairs. The owner imported it to the USA from Canada. A marvelous car and strong acceleration....although it lacks the outright torque and "guts" of the XJR/6.

The Ser III cars are so nice. The only way to improve them is to add more power. Everything else is almost ideal....in an olde-world way. The truth is, though, that the XJR does everything better. It can never duplicate the Ser III feel, though.

didn't realize they weighed the same .. the ser. III seems like a tank, but I guess it's not as heavy as I thought. I have one of each for the perfect balance (98 xjr, 86 ser III).

 

ya i do have to agree the Ser III ride like glass, and the highway power is smooth and strong, so i bought an xjr for performance now and will leave the xj6 engine as is.
