Maxi, they changed the sleeves and cranks on them , why I could not tell you, I think it was a bad experiment ohnestly ! Dyno a Crono RS7/N or better yet RS7/T !! These engines are 7 port monsters !! I think Nova thought the new ones would be the same ! Remember it's a woman in charge now.
I just can't believe the Italians went for this ???? Culturely speeking of course , I have nothing again women being in charge.... Of womenly things .... Not Manly stuff! Well now that my rant is over
The newer 2000 series 7 port mills should be a whole lot better! They have 14 mm cranks with the standard bearings in them.
Who has a 367 pistn/sleeve they can measure and compair to say.. a P5 piston/sleeve #s ??? Let's see some real numbers ,like deck heights, exaustport to top of sleeve dim and lip thickness at the top of the sleeve ?
This should give some insight to the evolution issues at hand .
