Is it worth upgrading injectors?
 

So I am going to replace my fuel injectors. I have a cylinder 3 misfire that happens maybe once a week, and I have narrowed it down to probably a fuel injector problem (maybe, hopefully?). The dealer I go to for stuff said they don't know what it is. I swapped the coils around and the misfire was still on #3. I did the idle "relearn," which didn't really help. So now I'm going to do new injectors.

Is there something other than stock I should get? If I get stock, can I just get one, or should I get six?

I am getting my car tuned in a few months after I get headers and HFCs from Z1. Other mods are cold air intake, dewla intake guide, intake ported plenum, remark axleback, and currently have test pipes but am swapping those for HFCs.

I am not going to ever use forced induction on this car, and am not planning on putting anything but 93 in my car.

You could swap the injector to another cylinder and see if the issues follows the injector …and if it does I would replace all 6 ….if you upgrade to a larger injector you will need to tune for the change …depending on future upgrades will dictate what size injector you should get ….with the upgrades listed you could still have it tuned with stock size injectors

That's what we all say at first...

I have cleaned/flow-tested injectors if you want to save some money. They're stock capacity.

There would be no benefit of upgraded injectors for you. Switch the injector around to see if that's the cause as stated before.

I'm not going to boost this car. I will buy a GTR before I put all that money into my Z.

That sounds like a good idea. Thanks!

Who flow tested your injectors? Can this be done myself as a trouble shooting method? I may be interested in yours.

I said that too...

A variety of companies will flow test their own injectors for you. Have to send them off though.

I mean there is a benefit, but it's not worth the price lol.

I sent mine to InjectorRX
