I think the late 70s 2.7L was a more popular conversion because it fit
better under the lid. It only had about 160 HP, the same as a 2.5 subie
motor.  There is an early 80's Vanagon with a Porsche engine for sale right
now in Bellingham WA.  I think the price is only 3500.  I did not get a good
look as I was in a hurry.  Seemed like an awfully low price. I should have
written down the phone number.
