no boost controller needed if you only want to run 13 psi and thats what the springs set at, just make sure you have the boost line connected to the side of the wastegate, that waste gate is pretty big, but if u have room why not?

triple ball bearing turbo? never heard of such a thing, but if you can spin the blade with your finger and it takes a second or more to stop, youre good
