My experience has been that South African parts places say they can do this
or that, but until you actually have the part in your hand nothing is sure.
They are really slow about getting back to you and sending the parts out.  To
me it is much better to have something here in the US, that you can buy and
have shipped to your place within a week, than to fool with importing stuff
from SA yourself.  Been there, done that, no fun.
Just my 2 cents, this is in no way an endorsement of the engine conversion in
question, just my opinion about getting stuff from SA directly versus through
an importer.
