I just found a leaky injector in bank 2. I am just going to swap all the injectors. I am running a BTR225 cam with PRC heads and all the fixins.

My question is, can I just swap to the LT4 injectors for now and leave the LT1 HPFP until I go boosted further down the road? I figure since They are about the same price I might as well just upgrade the injectors now while I'm doing it but I dont know if the LT1 high pressure pump plays nice with the LT4 injectors. I'm pushing around 570 at the wheel. I know I also need to replace to two high pressure lines that come from the pump as well.

It all depends on if your ecm and lower the duty cycle to account for the larger flow rate. I think the window is normally like 30 percent of correcton.
Think of it as how long do you leave a door open to let 10 people in. If you make the door bigger then that same time open will let more than 10 peope in so you change what variable you can to account for the bigger door, which is time spent open.

So are you saying as long as its tuned? I would assume it would need a new tune to make up for the larger injectors but is there any reason aside from a tune that it wouldn't work or is a bad idea?

Yea you would just need to tune it for them. It should work fine. They usually suggest replace the steel lines from the pump to the rails because the ball and socket connection won't want to reseal. That being said, I've reused all of the steel lines I've taken off for high pressure fuel systems as long as i didn't see any deformation in the sealing area.
