I will be receiving a set of RC 440 injectors for my 92 GSR today, and will evantually be getting a hondata 4b and f-max turbo kit. Is it okay for me to install these injectors now? Will the car know they are a different size and adjust accordingly?

 

Until you have the hondata your car will not idle with the 440's in the car, as the injectors are huge compared to stock. You will not even ba able to use a FPR to correct for the larger amount of fuel. The largest that you can use with the stock ECU is 370 cc/min.
