Hi,

  I've been out in my I-4 gas motored 84 and am just catching up on email.
I've never seen a "package deal" kit for the install of a
Golf/rabbit/whatever motor into a van.  If you have access to a diesel
vanagon, you'll find everything (almost) already figured out for you,
because the motors are almost identical.
  Neil's conversion is more complicated than simply following the diesel
set-up but using a gas inline four, which are indeed available and cheap.
Sticking a gas inline four in a vanagon is not difficult, more a bolt in.
 The fellow who did mine (he is a millwright/woodworker) did the whole
thing in one day with no issues...well the "low coolant" blinker wasn't
working..still isn't.
  I won't try to "sell" you this type conversion, but it certainly seems
like the least complicated and least expensive option out there...if you
have a basic knowledge of VWs and access to a diesel van or a set of parts
for the conversion.
  Mine just did yet another 2500 miles round trip, no problems, excellent
mileage and good highway speed.
