I asked this question a while back. Yes Vito's are Wiseco's. However some people have mixed emotions with them, some people stand by them others have had them blow up and wipe out a perfect motor. Vito's modifys them to their specs and they take 1mm off the exhaust side of the piston. This is supposed to get you more power almost like a port job. In my opinion i would go with Wiseco. They wouldnt be the leading piston manufacturer if they sucked and they know what works to get the most power and life out of them. The choice is up to you.
