Karl,

I finally got my 2.1 installed about a month ago, just two days before our
planned trip from Phx to Vancouver - Hell of a test run; doncha think?  I
had purchased the engine from Damian Shaw (great guy, BTW) about a year
earlier, but due to sime medical problems wasn't able to work on it for a
while.

Anyway, I installed the entire 2.1 system - it just seemed to be the right
thing to do.  This way I have the most up-to-date system overall.  Don't
know if my judgment was right, but it's done!

Problems were relatively minor.  The biggest I recall was the surprise that
I had to replace the big plastic pipes, since they are different lengths
for the new system.  The dashpot for the charcoal cannister needs to be
relocated outside the engine compartment (no room for the larger air
cleaner).  relocating the CPU inside the van required using a 2" hole saw
and a threaded rivet gun for mounting the cover. I don't recall any other
changes that were unexpected, and will report to you if I recall any.  It
was just a lot of work, since I had the tranny out and was replacing all of
the fuel tank lines at the same time.

Final results:  Better and smoother power and more torque (by seat-of-the-
pants measurement).  Seems to be quieter than the 1.9 (heavier exhaust
components?).  The 2.1 cooling system seems much easier to bleed, and the
position of the thermostat housing has to be an improvement (the 1.9 t'
housing is a bitch to get off if the bolts have corroded, and they usually
have).  If I had it to do over again (thank God I don't), I'd do it the
same way.

Incidentally, I had a .77 4th gear installed during the tranny rebuild, and
am not looking back on that one.  My theory on 2.1l stretch bolt problems
is that they are due in large part to long-term over-revving.  I am now
cruising quite comfortable at 3800-4000 rpm, while with the stock gearing I
was regularly well over 4K (long flat desert drives).

Good luck,

Karl Wolz
