I was wondering if i could run 440cc injectors for a max of 375 hp. The price from the 440's to the 500's is a huge jump. Thanks

 

I think your gonna need more than 440's for 375hp.Whay kind of injectors were you looking for?I knew b18bturbo is having an awesome groupbuy on injectors all the way up to 1000cc.

 

I think you should just play it safe and go with 720cc injectors if you are looking for that kind of power. You should be able to do it with 550cc injectors but at a higher fuel pressure than stock. I assume you have some sort of fuel management system if you want that kind of power. Why risk leaning out?

 

This question is hard to answer..You need to tell us your whole fuel managment setup..I have seen 440s do 375hp but its pushing it.

 

I was looking to get some RC injectors. I Want something that is going to fit in without modifying. If i get 550cc peak and hold injectors, will alls i need is a resistor box to run correctly?

Honestly i was going with the 440s b/c they are cheap(280 shipped) and i won't have to deal with buying a resister box.

So i should definitely should go with more than 440s huh...

 

I have a Walboro 255 fuel pump, AEM fuel rail, AEM FPR, Vortec FMU(not installed yet), and fuel gauge, and V-afc.

 

So your planning on the afc hack.Most people dont get rc's but dsm injectors and a resistor since its the cheapest.If your planning a afc hack then you dont need the FMU.From what i heard fmu's suck a$$ cause of fuel pressures above and beyond 100psi.

 

Dont do a hack just buy a missing link...and run it that way...thats what i did...I run 1 bar daily

 

$280 is cheap for 440's? i've seen 550's go for $250...

 

440's, 550's, 720's.... I was planning on hondata in the future. I also have a missing link at home. A v-afc right now for minor tuning as of right now. I am just keeping my options open so that i can make my best decision. Should i figure out what management i am using first and then look into what injectors i should use? Thanks

 

Go hondata, and get at least 720cc's. I had my 720cc's idling like stock, i am i just upgraded to 900cc's. These will idle like stock as well. If you can idle the injectors, then there is no reason that you would want to go with smaller ones. IMO, if you are planning on a built block and some serious psi 900cc's are the way to go.

 

I don't understand if you get hondata that you have to get higher cc injectors... Is there a reason for that?

 

I would get Hondata and some MSD 72 lb/hr injectors unless you can find the same RC Engineering injectors cheaper.

 

you dont HAVE to get large injectors but why not take full advantage of hondata's ability to make any injector idle.
