Hey guys.. A few quick questions. I've got a GSR swap in my ek and I bought a used Jackson Racing Super Charger with an 8 lb pulley. I still need to get injectors and possibly a fuel pump before I install it.
My question is: What size of injectors should I get I know that so many people put too big of an injector when the go F/I and it won't atomize the fuel properly. I was thinking of getting 440cc but wasn't sure. Also, do I need to upgrade my fuel pump and get an adjustable regulator? Any other suggestions on what I should upgrade?

I almost hate asking questions on this forum because so many people flame you for not searching. I searched! Thanks for any help.

You should post your JRSC questions in this thread.

It's not so much atomization, it's the non-linear opperation at low pulse widths (idle). Nearly any brand will be okay below 700cc - good for >400 on pump, >300 on e85.

The stock fuel pump will struggle past 225hp, so a 190lph pump would be a good idea. This all assumes you're going to use an EMS and not an FMU.

i used rc 440's and a 255hp fuel pump in my gsr when it was low boost turbo about 8lbs i think it would be fine for a JRSC at 8lbs. just my 2 cents tho.

use rc 310 or 440cc injectors iv used both, get your self tuned though because it wont run right with those injectors and fuel pump espeacially under boost, tie open the bypass valve and head over to your tuner and get a engine managment like a hondata s100,
