what size injectors do i need? I plan on having about 400-450hp what would be the best size? right now i have rc 550cc but i dont think thats gonna work out with my setup. i was thinking rc 750cc but i have no idea when it comes to injectors and hp. thanks guys

 

RC 750 sats will be more then enough make sure you get a walbro 255 pump and u should be good to go
go with stats over peak and hold, no need to wire up a box and they are alot easier to tune with and i have see tuners have a easyer time setting up the idel with them

 

Thanks a lot bro. yea i already got the fuel pump, now i just gotta get these rc 750cc
