        I would say Gianelli Fire :thumb

        Gives you a good top speed with a setup like this, looks good and is available new for a reasonable price.

          – What about Polini top one or Simonini proline. Do they fit on SI without modification?

          – I have read that there were some problems with Gianelli fire (SI model), breaking the holder (bolt for fixing the
          motor). Is there any tip for proper

            I don’t know if the other two fill fit a SI, but if when you mount the Fire you must make sure there is no tension on the “holder”. if there is no tension on it it should not break.
