What do you guys suggest I use for fuel injectors? I have a street ported s4 motor using s5 rotors and TII housings. I've read various things as always there's debate. 460s will probably work just fine but I want to make sure I have sufficient fuel for the port and was considering 550s. Maybe 440s for the primaries and 550s for the secondaries? I dunno, I can't decide and wanted some good knowledgeable honest opinions. Thanks guys...ibmoredebate

 

I think a 460-550 combo be PLENTY of fuel.

But what are you using to control it?

 

I don't have a stand alone, but was planning on purchasing an s-afc. Motor hasn't been turned over since it was rebuilt yet, but the afc is next on my list of things to purchase.
