Hey, just making plans for the winter in building my D16 right(finally)! My goal is 350-400 hp, t3/t4, built internals, etc...
I need to know what would be a safe size injector to go with for a daily driver, i don't think my 450's cc will handle it.

 

550s-660s

 

 

depends on fuel press

 

might as well get 750's there usually the same price as the rest and that way your not having to upgrade and sell your old ones if you need alittle extra. thats what i did with my b16a, and i wasnt even shooting for as much hp as you. you never know what you will do in the future though. so thats why i got mine because i was upgrading from the 450's as well. i found some high saturated 750's too so i didnt have to get a resister box and wire it up.
