Talking about a cars age is rubbish, there are plenty of 150k plus valvers out there pushing 150 bhp plus with just the WUR mod. That they are 18 years old is immaterial. They are no slower now than they were when they sold new (in fact usually they are quicker)
As for comparing my 1.9 to a standard 16v, why not, we are talking same power bracket and that puts both engines on a level playing field so the comparison can be made to show that the low down grunt of the 8v pulls my Mk2 away from similar powered 16v Mk2. Now if this topic was about standard cars then of course 16v's are going to be the best choice.
