Hi Gerhard!
No problems at all.
The conversion is complete. It was done for me by a crowd called Gensis Automotive in MIlnerton, Cape Town... What is most disconcerting is that they have completely disappeared!! Off face book, website closed.... rather scary.
My conversion however went really well and although it is a lot of work ( Custom engine mountings, BMW 740i Radiator fitting, 2" body lift for clearances, Spitronic management system and dyno tune, exhaust fabrication etc) it was well worth the effort and money!
It cost me R50k to have it done and I supplied my own motor and gearbox.
I opted to use the Lexus Autobox just in case the extra power was going to wreck my Pajero box

Also used the Pajero transfer box and Genesis made up special adaptor plates and things to make it all happen so that my 4x4 still works, low range and all.
The power is awesome, the sound is addictive but just a word of caution: if you're trying to improve your fuel consumption then you are heading in the wrong direction. People claiming 10km/l with a Lexus V8 are likely getting petrol fumes in the cabin that are hampering their calculations. Truthfully I would be delighted to get 6km/l in town and 7 or 8 on the open road are fairly realistic.
If however you are wanting a FUN vehicle that is kinda different and kicks some ass then you have come to the right place
Loving the V8!
