for a all motor build, when is it definitely necessary to change the stock jdm injectors to lets say 440s?

 

i was under the impression 440's were only necessary for a boost build. 330's should be fine? someone correct me if i'm wrong...

 

440s are huge on an all motor setup unless you are pushing a lot of power. I was on 370s around 60% DC and was making around 210whp. go to the RC Engineering site and calculate the size injectors you think you will need for your setup.

 

440 on an all motor set up are crazy unless the compression is through the roof. I would go smaller.
