i have an 89 civic ls turbo, i want to run 10psi. im going to get an safc, should i get 440cc dsm injectors or 550cc rc's, or is there a different setup i should do for fuel.

 

440's would work fine....550's there is a chance you wont be able to lean the afc out enough...You can go with like turboedit ecu program and chip yur ecu that way you will be able to pull timing in boost to keep from partial throttle detonation and you can fine tune with the afc, thats what i will be running very soon...I run afc hack 450's and have a timing program written to pull timing under boost, i will eventually go total turboedit but I just dont have the time with tryin to graduate college....
