I'd get a reconn'ed 1.6 or 1.8 with some kind of guarantee or from a very reputable source if possible, and just swap over the Supersport cams and your sump, and grind off the block as needed to fit. 2001 was around the swapover date from Eu2 to EU3, so may need to check for that. I wouldn't get a VVC as I think the wiring would have to change. If your long term power ideal is that of a VVC (150?) - maybe, but if you want more, a standard 1.8 may be a better starting point. VVC Trophy engine (with the stronger pistons and 160 BHP) is another option, but if you have long term plans, they would probably involve forged pistons at some point anyway. [What I did when my 2001 1.6 popped was try and build up a new engine myself. Took ages, almost worked out, but ended up needing to go to an engine builder in the end, so cost more than planned. With hindhight, dropping in a reconn'ed 1.8 and swapping over the cams/sump would have been more cost effective]
