I have a full opened exhaust, all Ragazzon from DP to rear muffler. That problem is solved. I am interested in if the 235 and 240 turbo are the same. Can I mount the 240 turbo on the 235 QV?
 
Yes is possible but nead a modification for a wastegate sistem . The 235 work in pressure and depressure . The 240 onli in depressure . Need put the wastegate of 235 cv and create a bypass for take pressure in the part cold of turbo . Is easy . The turbo is the same cange onli the impeller . The turbo of 240 have much power at hy rpm
 
Is strange you have break the turbo . The ecu map is ok ?

The only thing I need to do is to replace the wastegate on the new turbo for the one on the 235?

I do not understand the thing you wrote about the bypass.

Do you maybe have some pictures?

The ECU is remapped.

But this problem is now lasting from the time I bought the car. I bought it used with 64.000 km, now it has 87.000 km.

Yes, I have read the guide and it is very useful, thank you for that.

I have but the upgrade pipe, will be installed with the new turbo.

But the pipe is not responsible for cracking the exhaust housing. High load/temperatures do that.

I also have a Turbosmart blow off (diverter valve) on the Turbo, much better then the original.
