Does anyone know where I can buy a turbo cluster? Thedealer wants $1100. Help

 

are you replacing the current turbo cluster? Getting one for an S does not make too much sense with the boost guage and all...

 

I am thinking of replacing it from a Cayenne S. The dealer told me that it would work, but they wanted $1100. Too much money.
On roadfly a Brit said he was able to pick one up for 350. Any suggestions where I could buy one for that price
