Here's a site I found one day here in the North East whilst looking for goodies for the VX

Should be a good start for sourcing out engine replacment parts.

I have not done business with these folks before so I cannot comment on thier service or availability of parts etc. I just happened to find the link one day and thought it might be usefull in the future. It's the only place I could find vehicross parts around here other than the dealer.

Select Isuzu on the left menu under Import parts or do a search for "vehicross" and see if they have what you're looking for.

FYI - Our engine code is: 6VE1
