CA18DET -- in Japan -- came with the white injectors 16600-56E00 or variation (16600-56E01, 16600-56E05, etc)

370cc

Next step up in Nissan factory injectors is the Yellow 444cc SR20DET injector, which is a big step up

Going too big can give you trouble at idle. It gets to the point where you can't get a short enough squirt for idle fuel mix. How big is too big, I don't know. Depends on many things. Someone else may have experience with a set up like yours.

Does,nt matter how big the injectors are as long as the engine is correctly tuned on the dyno after installation,otherwise you are wasting your time and dollars

Are you running a Haltech or Mega SQRT?

As previously mentioned, if you fit bigger injectors it will require an ECM retune. Without the retune it'll run very rich -- I'd guess it would start but then stall as it warms up. Maybe it will run long enough to get into closed-loop mode and start running correctly

You can test your injectors before shelling out coin for new ones

Also do a fuel volume test, especially when it idles OK but doesn't run right when driving

Have you examine the fuel pressure after the revs come up? Sometime the starting & idle pressure are OK, but not the full pressure
