The Carrera intake is popular for EFI conversions. The stock flat "pancake" 930 intake is not an optimal design when it comes to flow.
The intake port sizes are different on a Carrera vs 930 so you would need to address that issue.
Many have done EFI conversions using the Carrera manifold, someone will chime in with their personal experiences. Do a search using the 911 forum, a ton of info should come up for you.
