I have a 89 n/a and i want to run bigger injectors. Not really too big just like some 89-91 TURBO II injectors in the primary spots and im thinking of 720's in the seconds. Is this a good setup to do without any complicatios.

 

Do you need to run bigger injectors or do you just want to? The stock NA injectors are sufficient for ~250hp, which you won't get without a bridgeport. Unless you're planning one, there is absolutely no need for you to run bigger injectors.

 

Your car will run poorly, get horrible gas milage and have less power.

Your money would be better spent on a S-AFC and dynotune. By using this to put LESS fuel into your engine your car will run better, get better gas milage and have significant performance gains.

 

Can you tell us why you want to do this?

Also read the FAQ.

 

the reason I was askin is, I was planning on hookin up a nitrous system and i wanted to know if this would be the right thing to do, meaning you have to have the fuel to keep it from leaning out right?

 

depends, are you going to run a wet or dry nitrous setup? A wet system if done well will not require any extra fuel from the injectors. It has its own injector for fuel that you'll need to supply pressurized fuel to. the dry setup however will require you to add more fuel with the injectors

 

Get a "wet" set-up with fuel and NOS jets.
This way you don't have to mess with the stock fuel injectors.

I see no reason why you should change the injectors.
