CAN running rich hurt

I own a 93 240sx, i just put a xs power t3 turbo kit on. My faze air and fuel ratio gauge is topped out on the rich scale can this hurt my car.

yes. your plugs will foul and in bad cases you will wash the oil off the cylinder walls and precipitate their rapid wear. I would not put much faith in a cheap A/F meter though. I am not familiar with the one you have but if it is not a wideband then it's readings are not to be relied upon any appreciable distance from the 14 range. read your plugs to confirm or refute what the A/F meter says.

my ka24de was completly stock before i installed the turbo. boost scares me right now im not going to even lie. I plan on doing some upgrades in the future. I keep my boost at only five psi what do u think is safe
