Hey, Im confused on what injectors I need to order. I have a B18B1 With Wiseco 11.7:1 std. bore, Crower 404s and going to see 8k+ rpm. Im not sure if i need 370cc or 470cc.. or higher? I also have a 225 fuel pump and fpr. Please let me know what injectors to get because i really dont know, thanks.

 

310's will be fine with your setup
Anything else is over kill

 

either would be fine for your setup and you wouldn't need to be going any higher for the power you'll be putting out. You could probably run stock injectors
