Hi, I know that a few of us have done the swap, but the threads I found are missing the images. I knwo that I have to drill to holes, can this be done with the engine in the car?
Does the front cover fit? I want to swap the steel oil pan in my Gems for an aluminium from a Thor engine as it starts leaking and I have to do the crankshaft seals probably, anyway too.

Although there are different part numbers for the front cover, late GEMS and Thor share the same one, the changover was at the 97-98 change. So that will fit. Not sure what holes you have to drill as the blocks are the same so I would have thought the sumps were interchangeable.

Hi Richard, thanks a lot! Unbelievable knowledge! From my - not the best - memory I had the idea that there were some wholes to drill and tap, but maybe my memory served me wrong. I will post an update, when I have will get more informations ...

I’m pretty sure that my 97 GEMS P38 sump is different than my 01 D2. IIRC the 01 sump has more bolt holes.

There are 14 bolts and three nuts as far as the manual is correct. But I think I found what holes I remembered from reading about this conversion:

Those are where the plate would be attached on a GEMS amd the holes in the bellhousing are threaded. Presumably, as the bolts go through the bellhousing into the sump, the thread needs to be drilled out so the bolts just pass through. Very easy to do with everything in place.
