Hi guys,

I never owned a Sirio engine and I think I want to try an EVO 4 STI for next season.

Could you please give me your opinions on quality, maintenace (conrod, bearings) and power characteristics in comparison to Nova and Picco engines?

How is the carb and has the engine a lot of toque or is it rather good in top end?

Thanks in advance.
