David,

Yes, i have.  I went the easy route, and kept
everything 1.9L (afm, in particular - the 2.1 airbox
won't fit in without some fabrication).  You probably
want to keep the 2.1 throttle body, and will possibly
have to re-route a couple vacuum hoses for the
distributor canister (although your '85 might come the
compatible way - my '84 ran stock vacuum hoses
differently than i needed).

Other than that, you will have to do a little bit of
tuning to trick the 1.9 ECU into thinking that 2.1 is
really 1.9 (not too difficult for someone experienced
with FI - which i am not).

It is pretty much just a bolt-on switch.  I just went
through this, so if you have any specific questions, i
may be able to answer them for you (or at least tell
you what i did :-)
