I took this off of nasioc.com. If you wonder if the VF39 is a direct fit here is the answer:
"Direct swap onto the WRX. The issue is with the Garrett center section and the oil line flare fitting.
Other things to note. THe compressor is very close to the TB plug. It works but its a tight fit. " - AzScoobie (I think)
