vitos big bore kit

NO.... from what I have read it is a little cheaper but not worth it. If money is the issue get a Vitos BB kit. There is nothing wrong with it other than you dont want to use the piston that comes with it very long. Most would suggest not using it at all and go ahead and get a wiesco. If money isn't an issue then get a LA Sleave BB kit.
 
It will cost very little more to get the vito's head/cylinder kit. There are some advantages to the kit vs a resleeve, they have tripple exhaust ports and also have the boyesen intake ports in them. If you resleeve then tripple exhaust won't be an option because of the lack of material around that area of the cylinder.
