I am currently in the process of swapping a 99 jdm ITR into my 93 Del Sol. I have read conflicting arguments on how much stock 240cc injectors can handle. I originally felt comfortable with keeping them stock but now I am inclined to believe that my car would perform better if I went up to 310cc as the 240cc would be at max duty cycle. I want to know if anyone else is running a similar setup and if so, what size injectors do you use and at what duty cycle do they run.

Specs include AEM hybrid CAI w/ velocity stack, toda replica 4-2-1 header, 2.5" no name straight header back, LW FW, LW crank pulley, no a/c, no p/s. Also going to be running a chipped and street tuned p28. No internal work.

I figured I should be sufficient on stock injectors but want to know what you all think.

Thanks,
Matt

 

you're fine with stock

 

Stock injectors are definitely enough for that set up
