Default Installing WRX injectors befor turbo?

Im getting ready to install my turbo, and I was planning on doing the parallel fuel mod this week. But I would like to install my WRX injectors while I have the manifold off the car.

Will my car run with the WRX injectors? or will it be really rich?

My car is pretty much stock right now, I do have a S-AFC installed so I could back off some of the fuel.

If you pull the max amount of fuel you will just barely get it to idle.

The S-AFC does +/-50%

I was thinking if the stock injectors are 280 and the WRX's are 420, thats like a 50% difference.

White 2.5rs - I dont have an FPR yet, do I really need one on a 99rs at ~6psi

Thanks

Interesting, but do you have your turbo installed? Im talking about befor the turbo is in.

but anyway if the wrx injectors are 380cc. does that mean if I pull 36% of fuel all the way across the board I will be back to normal. Or do things not work that way?

Thanks

Start with -20% all around in Lo settings and -15% in hi settings.

watch your EGT gauge and set it to reach 1500F cruising and 1400-1450 WOT

i was surprised to find that my car idles perfectly with no correction with my WRX injectors....

wierd and I need to have them and my stockers flow tested for piece of mind but its the truth!!!

with almost no internal adjustment from the computer!! about -5 - -10% which was normal for idling in closed loop with my stockers.

the ecu is capable or a +/- 20% fuel trim. i dont see how anyone's car can run fine w/o fuel managment w/ WRX injectors.

my Turbo Legacy EJ22t injectors, are only 100cc over stock and my car ran like CRAP-OLA when i put them in and started it up w/o my emanage. I am idling at -37%. If it was not running boost it would be -37 across the board to make it run like stock.

i've been running with wrx injectors with my stock ecu for about 1k miles. with no corrections at low throttle and no corrections at idle. only corrections are at high throttle for boost.

then you are running extremely rich at idle. Your o2 sensor fuel trim is likely maxed. im surprised the ECU hasnt thrown a CEL for this

If you continue to run this rich, the unburned fuel in the exhaust system will ruin the catalyst. Your spark plugs will eventually foul as well, then you will have a misfire problem.

Fuel managment is important guys, dont skimp on it. Dont expect your ECU to take care of everything.

Thanks for the input guys, I decided to hold off on the injectors, but I did do the parallel fuel mod, and paint the manifold while I was at it.

unsung - nope I monitor my fuel trims very closely while road tuning with the emanage. I can assure you that it idles at under 10% corection on my car and at perfectly stoic A/F (LM1).

I want to get the WRXs flowed against my stockers real bad. I was concerned at first, but it is reasuring to see other MY99 RS people have had the same experience.
