The SR has the same performance as any other NA My brother got told by many many people his was quick for a 1.3, Sham was actually finding it quite difficult to keep up with him when we went on some country roads and his has a 4EFTE engine!! NO joke!! Atleast 5 people stopped my brother and wanted a peak of whats under the bonnet, alot seemed to think it was a Turbo - maybe because of the TGTT sticker. I was actually quite impressed with the first drive in mine ;) (If I ever do take it out I don't go past 3000rpm though because thats when you can hear its a NA!!) Also I hardly take it out, once a year or something.
