I've just purchased a Small Bumper MK2 GTi 16v over the weekend, and at the time, and as far as I knew and the previous owner told me, it was an 1800 16v.
I knew it had a replacement engine in 2003, which had 34,000 miles on it (seeming quite low for an 1800?). I found the bill for this and noticed it said "2.0 16v". I find it hard to believe that the previous owner didn't know this, but he didn't seem to mention it at all?
So I'm trying to insure it today, but I'm not sure what to insure it as, how do I tell what the engine is, are there any easy differentiations from the 1800? They seem to look pretty similar to my untrained eye?
I've been looking at pictures and it seems to look quite like this 2.0 16v (with the metal inlet pipe)

Also, I used to an 1800 16v a few years back, and I'm sure that the DOHC 16v writing wasn't painted blue as with my new one?
Sorry I don't have any pictures as I'm at work.
Any help would be greatly appreciated here! Thanks!
