Default Should I step down my injectors?

My 1999 Camaro Z28 was originally rear mounted turbo but switching to a simpler cam/boltons and eventually nitrous setup.

I have a walbro pump, kenne bell boost-a-pump with a hot wire kit and 60 lbs injectors.

The planned setup:

FAST 78mm intake manifold (unported)
Throttle body to match
Lid/Filter/smooth bellows
TSP Tsunami Cam
241 Heads with springs
Pacesetter 1 3/4" primary long tubes
QTP manual cutouts (for now)
High flowcat 3" Y pipe
3" intermediate to a magnaflow catback

Will probably end up doing 100-125 wetshot with a plate

Will the 60lbs be bad/inefficient at the % they will be running at? I'm willing to step down.. but I don't know anyone interested in swapping for sayyyy 42lbs injectors. All insight is appreciated!

What kind of power will you be looking at hitting the nitrous?

you should be fine. you are running a wet shot instead of a dry... those injectors should work fine. you may have to do a little tuning on the injectors, but they should be fine.

The only concern i have is I won't be putting the nitrous on for a bit until i sell some of my turbo parts from my other car.

You think all motor Frost will be able to tune with those injectors? (Mail order tune)

I'd give your tuner a ring (or an email) and see what he thinks, as he is ultimately going to be the one making the tune.

I would imagine you shouldn't have any tuning issues running a quality 60# injector N/A.

When your turbo car is idling and cruising it's not in boost and the 60# injectors don't drown the engine, right?
