I have a Z6 with a st2 ported Y8 head, skunk2 intake and 68mm tb, Eagle h-beams, and SRP turbo pistons 9-1. Im looking for 275-300hp. Which ball bearing turbo and injectors should i get. Money isnt really a question, I just want a turbo that will spool quickly and make some good power. Also I have a set of RC 310cc inj.s. Will they work with that power level?

450s no thanks and 550s might even be cuttin it close, especially if you decide to do more with the car later...^^ as recommended above 650s to be safe. Id rather have a little too much and be tuned down, then want to tune up later and find out i have to spend 300+ on new injectores all over again... but thats just me. Turbo recommended is great, to $$ for my blood, but it will do the trick. sounds like you have a nice build going there keep us posted, and pics are a plus :)

The injector size is also dependent on the fuel pressure and the tune used in the ends yes 550 is like just a bit over adequate, but that deceision should be based on what you plan to do with the car later.

As for spool time and the WHP u want cant beat a GT28

Agreed on the disco potato. For that power level it will be great, and allow some room for when you inevitably want to wind the boost up a little more after a while ;)

GT28 Disco Potato is a real good choice.

GT3076R .63 is an other good choice if you think need more whp later.
I have one and I love it!

Get 680cc injectors MINIMUM to be safe. I recommend you PTE 880cc.
When you'll need more boost (pretty sure you will), you'll have the correct injector size.
They are the same price, so why not. ;)

2.5" intercooler piping maximum. I use 2" on hot side and 2.5" on cold side.
