ok, I think I've ditched the vito's big bore plans and am gonna go with porting my cylinders. I've been doing some reading on porting and some on strokers.
when I search on here for porting passion and fast come up the most often. what are your recommendations here, or are there other places to do it?
should I just send my cylinders off and do the reasemble myself?
what would the cost difference be between getting a stroke crank and just staying with the stock one? will the stock crank hold up?
