Sr20det 550cc or 740cc injectors

[rb20det180sx]

Hey i have a Greddy TD05H-18G turbo on my sr20det and i plan to run 18 to 20psi on that track. i already have a tuned ecu for z32 maf 550cc injectors and gt2871r turbo.. would that work fine or what i have to upgrade to 740cc injectors?

hey you live in chino too eh? coolyou would just have to get your ecu retuned to run them pretty much.

I have 550's and that seems to be plenty for me. I would just stick with those, I am on 18 pounds and still running a little rich. I have a mine's ecu though, so your tuned ecu is probably much better.
