1.) Does anyone have any information regarding the posibility of rebuilding the old 4.2 to the newer 5.0 version of the RRS? Is this posible?
2.) Tips regarding which workshops that can perform this conversion?
3.) If not possible is there any workshops that can do a good job of replacing the old 4.2 and transmission of the SC 4.2?
4.) Is it possible to get a proper V8 in a Discovery 4?

1. No.
2. No.
3. Anyone who is able to remember which connectors go where and which nuts go on which mounts should be able to do a swap.
4. Yes. Ask Disco Mikey. Regards etc.,

Making this kind of change is too expensive and you're better off just trading it in for a 5.0 SC. that's what we would do here in Canada.

Please answer the question if you can. I am from Norway not Canada. It is almost impossible to buy 2010-2012 SC 5.0l, cheaper to rebuild due to government regulations and Extreme taxis on import of these cars.

I don't see why it shouldn't be possible as the underpinnings of the car are still a Discovery 3, just the bodywork and engines were upgraded in 2010 not the basic underpinnings. As stated above member Disco-Mikey has already converted a D4 to a V8, but IIRC it was a TDv8 lump that he installed not a petrol engine. 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it
2018 Melting Silver Mini Countryman PHEV - soon to be replaced
2015MY Corris Grey SDv6 HSE Dynamic, the best car I have ever owned, totally reliable only a cou0le of rattles in 3 years, now no longer in my care
Also in my garage is a 1996 TDi300 Defender 90 County HT made into a fake CSW

Thank you for an informative answer!

wouldn't it be easier to just import a full 5.0 SC engine and retrofit that? --

Yes, that was what I would like to do, I have to replace the hole engine With Control systems but from whom? Have to import this as Complete as possible because there are no specialist in Norway. Also see the replay above.
I also Wonder if I could drive the car England or another country in Europe and have the workshop abroad do the work.
I dont know.
Thank you for the replay!

Was thinking it would be best to drive it to Scotland, fly home, etc

Agree. Just waiting for more information about which workshop or persons who can perform this. There is a lot of options regarding both cars.

Plenty of aftermarket specialists and Indies in Scotland and also Northern England who would be delighted to take you money to carry out the job - best to contact somebody like Disco-Mikey on this forum - he is in Dundee but there are companies in Killin, Auchterarder and Newcastle well up to doing this sort of work. Might even be worth contacting BAS (Bell Auto Services) in York or Twisted Performance (although their speciality is Defenders rather than D3/D4/RRS). Dare I mention them here........There is even Kahn and Overfinch further south 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it
