Default Injectors, Rebuild? Buy new? Clean? Flow test?

Hey everyone

I have a 2005 EJ255 I am building. The car has 190,000 on it. HP plans in the low 300s. What should I do these injectors to get them ready?

Should I just clean them, get them flow tested, throw them away and buy newer ones?

What else in the fuel system should I be paying attention to? I am going to replace the fuel filter and replace the fuel fump with a 255. Open to all suggestions.

Also, I have a great ultrasonic cleaner if it makes a difference. Clean them then get them flow tested?

Thanks

-Dave

Are they the stock injectors from your 2005 WRX? If so, they're too small, you will need larger ones to support those power goals. However, the newer WRX and STi 560cc top feed injectors will drop right in and are good for a bit over 300whp. You can surely find a used set for cheap in the classifieds.

probably will be almost the same price to buy new on nasioc than having yours properly cleaned and flow tested... let me know if you decide to buy new, i have set of NIB DW top feed 1000cc...

Cleaning and flow testing is cheap, and cheap insurance for any used injector.

Checkout WitchHunter or daestchwerks (check the spelling on that last one). I sent my injectors to WitchHunter and had a great experience.

These are the yellow chubby injectors out of a 2005 FXT EJ255 engine, not my WRX

Does this make a difference? I was doing some research and I am pretty sure I don't need to upgrade my injectors. I would like to consider all potential options though.
