That's the good thing about Clio's there is so much info about them, found a great guide to remove front bumper couldn't believe how few fixing there was.
You're doing well, it took me 3 hours to get my front bumper off.
The first time anyway.
Yes I think the 1.2 engine would fit easier, it's quite a tight bay, would not like to change the belts in situ like Dome did. Hope the new engine is not a shitter though. Don't fancy taking it out again.
