its safe to run it at 14 but it might run a little rough. unplug the battery for a few mins to restart the computer.

but buy a better head gasket in the near future.

Yes. If you turn the boost up with that larger turbo and no tuning. You're going to run lean. Not good.

The pump, injectors, maf, and igniter are the main things you need besides the tune, that is the most important thing. 3 things make an engine run, air fuel and spark, you obviously have the air from the turbo and the ability to read it from the maf, the fuel from the pump and injectors, and the spark from the igniter. So with a nice tune, you should be good to go, the HG is only a huge worry if the tune sucks, but still a good idea Just in Case.
