What type of charger/turbo are you looking at? The Neuspeed charger is a compact unit that provides decent hp. There is one on the vwvortex board for 1800.00 Search under arnette77 in the mk iv classifieds.

I own an after market turbo system for my Scirocco. When it runs right it hauls...but its hard to keep it running correctly. I just changed a head gasket on Friday because it was running lean. Of course this situation can happen with superchargers.

My opinion is go with supercharger.
