I want to know the best select of 440 cc injector.

 

What mods are currently done to your car? Are do you have someone lined up to tune it in order to make it run with the larger injectors?

 

Now it's a stock engine
The header is flushing the stock to fit the exhaust port. The catalyst was removed.
borua muffler.
7600 rpm with stock pulley
Either way, we plan to form 15%.
I use FA53.I am considering using BOSCH 968 440 cc.

 

With just an exhaust and pulley.....not sure larger injectors are going to gain you anything. If you are able to dial in the A/F ratios you need with your current injectors.....what are the 440's going to get you?

 

Both are 15% assembled
It is because I do not intend to use it over 90% duty cycle. Do you think that it is enough to add wall correction and intake air temperature correction?
I do not need it unless I run a truck, but I need it.
Do you know 440cc recommended injectors? I am not questioning to satisfy your interests.

 

What????

 

 

He's not going to run JCW injectors OR even the stock S injectors to the limit with just a pulley and exhaust.
