Default 30 lb/hr injectors on a stock L98?

I was planning on modding my engine after the summer when I finished school, but it seems some of my injectors are going bad so I want to get them upgraded now. How well would my stock L98 work with 30 lb/hr accel fuel injectors? If it wont work, then what flow rate should I go with? The 30 lb/hr injectors are the same price as 21 lb/hr ones, so if I'm gonna get new ones anyway I might as well go as high as I can.

I think as long as you can tune for the bigger injector it never hurts to leave room for improvement.

if you do a chip then there no problem.............


but........... if not it will run rich as fuck. but as a work around i've pulled apart the fuel press reg and made it run at about 25psi and its ok.



i did it for the blower with an fmu it ran on 25 then the fmu went to 90 under boost. still wasn't really enough but it helped cause i was to cheap to have a chip burned

Joe! why don`t you just leave it alone untill you make the mods???????? you are thinking about doing extra work that will likely give you problems as well as bad mileage!

I wouldn't plan on 30 lbs/hr unless you are planning on running about 5-8psi of boost.

I need new injectors because 2 of mine are bad. One is down to 8.0 ohms and the other is at 14.4 ohms while the rest are about 18.0. One cylinder is always misfiring and the other does sometimes. That gives me crap fuel economy also.

I was thinking about getting a supercharger on top of the mods I planned for the fall but the supercharger would come probably years later. If 30# injectors are going to give me problems now, then I'm not gonna go that route just yet. You say 24# ones will work reasonably well on a stock L98? I'll probably stick to those then.
