Don,

I believe the block is the same, but the crankshaft is a bit more
stroked-out than the 1800cc. Nonetheless, an upgrade from 1800 to
2000cc Type IV is no big sweat. Make sure either of your oil coolers
is in good shape, though. :)

To the list,

Is it conceivable to put Digijet stuff on a Type IV motor? That way, a
Vanagon up to '85 will pass emissions with a Type IV in it. Sure, I
lose HP, but if (sorry, WHEN) my heads leak, I might very well be in a
position to not be able to afford these long-shot engine swaps- I can
however, use an inexpensive, easy to find Type IV around- or build one
up! Besides, Type IVs are a known quantity to me. Rabbit motors
aren't- and empirical observation leads me to believe that their
reliability is just as if not more precarious than the good ol' Type IV.

Best regards,
Sam
P.S. Darwin may be dead, but I hope "Creation Science"- which isn't
science, but a means to a religious/political end- dies too, soon.
