I hesitate to provide my own thoughts as I'm not overly familiar with the
1.9

Though the samba thread I refer to isn't very long, this post from that
samba thread may shed some light:

It would be adaptable to the 1.9. You would just need to find the
appropriate 2.1 core parts that they may want sent to them as cores and
then install their system on the engine with what ever 2.1 parts you need
to keep and use. The biggest issue will be either changing over the cooling
system to the 2.1 style so that the 2.1 air cleaner can be used or figuring
out how to adapt the GW system to the 1.9 air cleaner set up. It's doable.
Plenty of people have put 2.1 engines in their early vans and swapped in
the digifant system with it. It's generally accepted that the 2.1 cooling
system is a bit better than the 1.9 set up.
