EW10J4 vs EW10J4S

[Paketbil_förare 0]

HI,

 

I'm planning a wild setup based on EW10J4. Today I discovered that internals in EW10J4 and EW10J4S are different, and J4 won't take so much boost than J4S. So it seems that my project hets little more expensive than I thought.

 

But what are the differences?

 

As I know, they have a completely different cylinder head, there's VVT in J4S but the valves are different. Maybe springs and retainers as well. Pistons are different, maybe also conrods... Do you know more differences?

 

Can you recommend a site or something for comparing part numbers?

catcar.info is an ok source of part numbers, not much in the way of specific dimensions however
