Depends on how much boost you want to run with that turbo. For an example, I run 440's on my RS-T, with the S16G turbo, and the Megasquirt for engine management, and I am about maxing the injectors out at 18 psi on 100 octane fuel. So depending on what your boost limit is going to be with that turbo, you may or may not need larger injectors. It's always wise to get larger ones though, that way you have the fuel there if you want to up the boost.

13.5 @108 MPH-2.2 60ft(stupid FWD!)
