Try changing your radiator cap first...

besides the cap anyone have any other ideas

Do you have a top or bottom mount turbo?

bottom mount

I'd say the cap also then and if you can try and pressure test the system. Whats the temps look like?

temps fine and then it overheats because the rad is empty and all the coolant is in the overflow and has spilled onto the shcok tower

If its not the cap, then make sure its bled properly...turn the heater on full blast, lift the front of the car up, massage the upper radiator hose to get as much bubble out.

And if that doesnt fix it, time to start troubleshooting it for a blown HG.
