im boosting my b6de with a t3 and am looking for 12 psi right now
i have a set of 324 cc injectors that i pulled from a 2.2L turbo 626 but im not sure if that will be the proper amount of fuel.
ideas?suggestions?

RX460cc's are what I am using.

psi is not a factor here. An HP goal would be a good starting point. Go to RC's website and use their injector calculator.

I don't think you'll be able to get 12psi of boost (t3/t4 as per your sig) with those little guys.

as a side note. you need to make sure your ECU can tune a large injector upgrade as well. What will you be using for an EMS?

wow..someone actually responded...t3/04 isnt exactly small...im having fitment issues...ill be managing it with a b6v8 b6t ecu, which should be fine and im shooting for about 250 hp right now

B6DE boosted i would stick with the MX6 injectors, way way better than the RX460's on this small displacement motor. I ran them on my Bored out BP. The main reason is idle. you cant cut the 460's back far enough so you run incredibly rich and idle suffers. the MX6 injectors are almost the same size that was on the GTR 323 motor. I have run both sizes on both motors and i would run the MX6 injectors.

any particular mx6 injectors? will they work decently with the b6t ecu?

They will work just fine. I was running the N/A injectors 310cc i believe but they will be better than the 460cc's for sure

If i were you i would run the BP26 ECU or the NA PB ECU, with a 92-93 engine bay harness (which you will have to swap out anyway to run the B6T ECU, the BP ECU red lines at 7200 instead of 6500 as well thats the difference of about 110mph to 132mph ), adjustable boost sensitive FPR, walbro fuel pump, BP external coil and dist., with a 2nd gen RX7 VAF. you will not need a piggy back or stand alone. there is enough adjustability in the VAF and FPR that you can get it dialed in dam close staying under that 12 to 14 psi range. I ran an NA BP ECU with my B6 Turbo motor and i turned about 238 to the wheels no piggy back.

another option if you were going to do a piggy back for your fuel, Buggs did it on his mx NA turbo BP. with the APEXI S AFC 2 and instead of running it on the TPS like your supposed to in the MX ,he pulled a 3BAR MAP from a RX7 and wired it to that. worked incredibly well and accurate going off of the exact manifold pressure instead of guessing off of the TPS position.

how did he wire a map to the tps sensor???????????????????????

He didnt, you wire it to power then run your vacume lines then wire it to the SAFC

oh.
i guess that makes sense, lol
i was confused as hell

It really makes for the best setup and most accurate use of the SAFC. I wish i would have thought of it before i sold my SAFC.

i had a megasquirt but the damn thing was so much trouble i sold it. i never could get the damn thing to trigger correctly even with a preset for 323 gtx(my car is close enough that i should have been able to get away with that setup)

id like a haltech but my wife would kill me if i got one, so for now b6t ecu w 33xcc injectors so i can get the thing running and later ill probably swap 450ishcc injectors and just get the haltech.
