As an 8v driver I would just add that's is very revealing that from about 1986/7 (when the first 16v came out) VW chose to continue to produce the 8v side by side with the 16v. Arguably, if the 16v head was a normal evolution (along the lines of fuel injection, disc brakes, ABS etc) then how come VW carried on with the 8v format both in 1.8 for the MK2 and 2.0 for the MK3? Answer: because they got it right first time round!
When the normally aspirated 20v 1.8 came out in the MK4 it only lasted one of two years to be replaced by the 2.0 8v from the Mk3 because although it was 'only' 115bhp compared to 125bhp 1.8 but it actually made some useful torque which is what you need for the real world.

NOT slating the 16v engine just sticking up for the underdog 8v: just like VW themselves did!
