You are getting ready to dump a truck load of money.

Plan then build, you will be much happier
Agree on all points I did plan and I am very happy (at 7.5/1 comp ratio and CIS by the way, but with electronic timing control). EFI would have probably made my build 25% more expensive and I was nearly 50% over my initial cost estimate already.

Another fact is that air cooled turbos run hot hot hot CHTs and no amount of EFI or timing control will prevent this. "Safe" is a relative term in the context of built 930s and lower comp ratios are relatively "safer." Fact.
