Insurance on turbo modification
 

I have E-mailed AA autosport in Shipley regarding a turbo conversion, has anybody had a turbo conversion done to your own ZS and what insurance company is best to use to declare the modification to and how much did it go up by? just want to make sure it's worth while doing before I commit to it 'cos as you know everythings up in todays' world as compared to 10 years back.
