First off where can i find these pistons ASAP, also I've got a A6 block thats 40over can i even get Vit. pistons that big?? I've heard that they are a millimeter smaller then stock bore, so if i ordered them 40over would they be a milli. to small thnx for the feedback

 

I dont think they make vitara's that big .010 is the biggest as far as I know. .040 is quite a bit to take out you might have some issues if you go for big boost after taking so much material out of those sleeves.

 

yea they make them that big. look on ebay

 

Yup, it is 0.020" over that is not common.
