Default sc injectors

well guys, after doing some digging i finally found aftermarket injectors for us.
i was a devoted tuner with a turbocharged,nitrous injected eagle talon. one thing i do know, that if you up your boost, you need to up your fuel. a lean condition is not good at all. i found injector rates and part numbers from accel for our 92-95 3.8 sc cars.

here goes:
................................flow rate...........accel number.......... price/6
stock...................... 21 lbs/hr...............150621................$173.69

step up 1.................23 lbs/hr...............150623................$173.69

step up 2.................24 lbs/hr................150624...............$173.69

step up 3.................26 lbs/hr................150626...............$178.69

step up 4.................30 lbs/hr................150630...............$194.39

these prices are from SUMMIT RACING

these numbers are for a set of 6 and trust me on this, as the boost goes up , the fuel needs to also.
hope this helps when you add a smaller pulley to raise the boost level

If you get injectors that use more fuel won't you have to get a Fuel Pump that can handle that much fuel.

Wont that also change your emissions?

as for emissions, if you are improving the air flow into and out of the engine, like in a different intake and open exhaust, under WOT this could cause your engine to run lean . the pcm controls the air/fuel ratio but at WOT the tend to run lean due to the increase airflow through the engine,
the pump will be ok unless you go to WOT for a very long run. this flow rate reading is at WOT. i would suggest that with any major mods to replace the fuel pump to a higher volume. but i seriously doubt that you will run it out of fuel with these injectors unless your pump is borderline anyay.

What about the output levels coming out of the exhaust (CO2 and the like) will it pass CA emmissions?

Your PCM (with the help of the O2, MAF and TPS) keep your mixture correct regardless of the larger injector. You won't be running rich, you just won't be able to run lean in high boost conditions.

i sold my talon to a guy for 4500 bux and got my bonneville. i loved the comfort of the bonny and the quickness too. one thing about a turbo with an auto trans, severe turbo lag !!!!!!!!! anything under 70 mph and it had to be in 3 rd gear to hit the nitrous or it would smoke the front tires. i had a NOS 50 shot wet system on it.

also anything under WOT , the pcm controls the dwell time of the injectors( duty cycle)
if you are running more boost, trust me,..... you dont want to run it lean
