93 4.9 injectors
So i've been looking around for easy performance bits for my L6 and I came across a forum where they talked about some mustang injectors that would go in and boosted pressure from 12 psi to 19. Anyone heard of this or done it? any help is appreciated.

The rating on fuel injectors is pounds per hour (flow) not pounds per square inch (force).
Changing the injectors to 19s also require that you install an adjustable fuel pressure regulator since the V8s and I6s run at different pressures. This mod by itself probably won't give an increase in power but will help if you modify the head and improve the cam to increase airflow.
IIRC the stock injectors should be good for about 175-185 Hp and most EFI 300s are 145-150 Hp and 260-275 Ft lbs torque.
YMMV
