hi guys , not sure if its been coverd before , but what is involved in fitting the r engine and gearbox into an 8.

i basicly have a 1997 xk8 in exelent condition with no rust undernieth and of the 6 xk8/rs ive had this is b far the best condition.

now, ive just been offerd an xkr engine and box for a steal of a price and was wondering what els i would need if i was to fit it into my current xk8.

thanks,
craig

 

You can do it, but....

To simplify something that is not simple, it's a lot of work and involves the computer, fuel delivery and wiring systems too, so just an engine/tranny swap will not do it. (For example, you need a 2nd fuel pump and wiring for it in the fuel tank.)

It is generally considered cheaper and easier to sell your existing normally aspirated car and buy an R type.

i thaught that would be the case. imay just fit a 4.2 if i get offerd a cheap one of those. i understand this is prety straight forward

 

like the other member said it is a lot of work but can be done if you have the donor car and swap out all the under hood wiring and some of the interior wiring going to the tank just put the fuel unit form the donor into your tank I did it on my 97 xk8 took me 3 days to do
