The 1991-1997 RSi was, as far as I know, a variant of the 95bhp 1.8 (1783cc, then 1794cc) F3P engine. My Renault sources quote this engine, which was also found in the early 1.8 RT and 1.8 Baccara (luxury model), as having 95bhp @ 5700rpm and 105lb/ft of torque @ 2800rpm. However, Ive also seen this engine quoted as available in 110bhp form - which I believe was available in the 96-on Phase 3 shape (when the 16v and Willy were discontinued). This latter engine had a slightly higher compression ratio.
The Autocar test for the 1996 RSi in 110bhp spec is 0-60 in 8.9 secs and a top whack of 118mph, its 30-70 is quoted as 9.2secs and the 50-70 in 5th as 11.2 secs.
Meanwhile, a 1991 test for the Clio 16v is 0-60 in 7.4 secs, top whack of 127mph, a 30-70 in 7.1 secs and 50-70 in 5th as 8.9 secs.
Im guessing that the RSi would pick up as well as the 16v would out of its post 4500rpm power band (16v has 116-119lb/ft torque at 4250rpm), but once the 16v hit that power band it would thoroughly demolish it.
