Engine Swap (scirocco to Jetta)

[mpeters6@rochester.rr.com (Marc Peterson)]

Any 1.8 block with work, physically, with any 1.8 head and manifold,  Where
you run into issues is with injection systems.  The simplest 1.8->1.8 swaps
are when you swap a different block under an existing head and retain the
existing injection.

In your case, the difference in HP is the compression ratio, the JH is 8.5:1
and the Digi is 10:1.  I think Digi will compensate for the differences, but
you will lose some low end off idle grunt.  (Digi has this issue already,
lowering compression will not help)
