If you can see the spray pattern is not good when the injectors are off the block, I'd send all four injectors out for ultrasonic cleaning and flow testing. Witchhunter Performance, RC Engineering, and Marren Fuel Injection all do an excellent job with FD injectors.

Poorly spraying injectors are not just annoying - if they clog and run lean they can blow your engine.

Are these the injectors that came with the used engine?

are they expensive to be clean out!!!
yes this injector is coming with the engine i just bought!!! ill probably think they got clog or somehow!!! i have a set of 1600cc n 1200cc!! should i put them on now to start the engine with! or should i wait and use the stock injector to start the engine first!!! because im going for big single turbo set up!!

1600s and 1200s are used as secondary injectors, which are not active when starting the engine.

I think Witchhunter charged $15-20 / ea. It's a very important maintenance item IMHO that should be done every few years or any time the vehicle has not been run for a very long time. Especially since you're planning to build and get tuned, it's important to know all the injectors are firing exactly 100% of their rating.
