OK, not a turbo, but still interesting. I had an email exchange recently with a friend in France, he has very strong links with the 'collection'. We'd not spoken in ages so I told him a little about my Twingo 172. He said' you know that Renault built one?' I didn't, but apparently they built a few with 1.6 and 2L engines with the idea of a one make series, they still have a 2L in the collection. It looks to be more like a clio Willaims in a Twingo body.
I found some pics online.

it didn't fit in with the image Renault wanted for the Twingo, a bit like the F1 powered Twingo....
