I have a 2.3 GoWesty in my 2wd GL. It came in a (salvage title) van
wrecked just 16K after the 2.3 was installed. This thing is pretty
quick so, shortly after its arrival, was christened 'White Lightning.'
This engine has a very tight feel and hits any mph target with what
feels like much less effort. This translates into a very relaxed
driving experience.
I would label this engine as a perfect  fit for this vehicle. Even
when I loaded it down with all my rafting equipment and two people
(estimate around 1500lbs,) I caught myself doing 85mph several times.
BTW all the above is while driving at 6500' plus. I consider the
performance to be amazing at this altitude and imagine that at sea
level it should be pretty surprising. This engine also came with a 30K
warranty, which GoWesty agreed to honor both when I took ownership and
also in the event that I transfer the engine into another Vanagon.

Gracias,
                    Miguel
