Hi folks,

I had an '84 Vanagon Westy for 16 years and 250k, and just jumped back on
the list for awhile just for fun. I did this conversion, and it's nice.  You
keep your exhaust system, and use a 1.9 water pump, but that's it.  The ECU
and wiring are the same.  Pretty straight forward.  The problem with the
2.1s is they tend to throw rods if the bearings are worn, so it's not a bad
idea to add an oil pressure gauge.

Here is a detailed write up from someone else who has done this:

Subject: transplant a 2.1 into an 84? worth it?

What do you all think about putting a 2.1 in an 84 1.9?  Would it be worth
it if it ran well and used less oil than my 1.9?  I don't plan on rebuilding
it, just resealing the heads and installing it.  What are some things to
look out for?  I would need the computer/harness yeah?  What else?  Thanks!
