I had a Volumex 2000 special engine from Kenia that was in my old 131 abarth and whe fit it inside for test and WOW .It goos like hell .Even with the 295 tyres spins the wheels easy all the time.I fit the Koni front and fit Bilstein group 4 from a Sport on rear.Like it drives now I will not fit the 131 abarth rear diff but will need the big brakes
