I have 2 Pix Firewalls with 6.3(1). On the Office side is a vpngroup defined and the split-tunnel option is configured. The remote Pix 501 can now connect to the Office PIX and the right information is given to the client.
But if the split tunnel is configured the client PIX make no NAT or PAT for my
Client computer. If I disable this option all works fine exept internet traffic is also encrypted and no sufing is possible. Any Ideas ???

If you're doing split tunnelling with EzVPN client on the PIX, you still need to have a standard nat/global pair defined for the non-encrypted outgoing traffic. Something like:
> global (outside) 1 interface
> nat (inside) 1 0.0.0.0 0.0.0.0
The PIX will use this translation for unencrypted traffic, but will encrypt the other traffic as defined by the SA's and the split tunnel list and send it over the tunnel to the EzVPN server.

The nat statement is in the config:

The nat statement is incorrect. You have:
> nat (inside) 0 0.0.0.0 0.0.0.0
which specifically tells the PIX not to nat the traffic. Change it to:
> nat (inside) 1 0.0.0.0 0.0.0.0
and you should be right.
