2.0 8v is far easier, 16v requires more parts. You'll need to source the zaust manifold & downpipe, either expensive & rare rocco 16v one, expensive 4 branch, or weld top half of 16v downpipe to bottom half of mk1 downpipe and bolt it to the std 16v manifold.
Airbox on a 16v is on the wrong side so some chopping is required to make it sit on the driverside inner wing, and the washer bottle needs to be moved.
