whats the difference between these or are they more or less the same.

 

There is quite a bit of difference between the two structuraly. Both made by Wiseco though. This like anything you will hear good and bad. I have had them in my banshee since the beginning of the year and no problems so far. The skirts are shorter, the intake holes are higher up on the piston, the rings are definitely different on the Vitos compared to regualr Wiseco pro lites, the domes of the pistons look to be shaped differently also. My squish was fine with the pro lites but not with the vito's, I had to double up and run two base gaskets to get the correct squish Vito's recommends. I'm running the cast Vito's power pistons and so far they seem fine. Still doesnt beat a good set of pipes and a port job. We did several things all at once so the difference seemed minimal. Cast are about the same price as pro lites.
