Would a 50 trim with a #6 also need 22 psi? Can stock injectors support that?

Hi Jimbo,
Does the peak torque of your turbo occur at the max
efficiency island in the compressor map ?

Stock injectors will get you to about 300 rwhp but you will have to run very high fp at the rail. We all know how dead these cars are off boost. If you want a street car that is good for 300 to 310rwhp at 18 to 20 psi than the 50 trim with the 6 hotside can not be beat. Very similar in performance to the k27/6 . using the 8 hotside will get you 10 more rwhp but you will sacrifice some much needed low end torque. If you plan on using the 8 hotside skip all the trims smaller than a 60-1. More than likely your after big power. There are some turbos that can produce 400 at the wheels on our cars at 20 or so psi. I wouldn't disclose witch one's because it will hurt some venders here who want to sell kits.

How high FPR do you need? I guess what you are saying is that you can take a load off of the fuel system by upsizing the injectors but it isn't immediately necessary.
