i have a 94 civic.
turbo d16z6, p28 soon to be uberdata chipped.

my question is,
which is the biggest injectors i can run without a resistor box?
i thought 440 were the biggest?, but i had heard some one had 550 that i could use.

what is the max whp for 440's?
i plan on ordering them today, so any info would be great.

thanks
kelly

 

i thought resistor boxes are required for a specific fuel injector type, not the actual size of the injector.

the biggest injector that you can run withour resistor is the 780cc from RC they are costly at 299 a set but they are saturated and do work fine. Talk to ben@importparts.com if you need them he has plenty over there.

i thought they didnt make a injectors (which ever one you dont need a resistor box to run) above 440/550?

Nope, they have 750cc Saturated ones now (you only need a resistor box for Peak and hold injectors) - https://honda-tech.com/zerothread?id=918428

 

you are thinking of the dsm 450cc and 440cc injectors. They are peak and hold injectors which require you to wire in a resistor box. Honestly I think wiring in the resistor box is definantely better than spending over $200 on rc injectors if you only need 440 or 450cc injectors. The resistor box really isn't hard to wire either.

 

i just ordered saturated 550's,
i was told i wouldnt need a resistor box.

 

These are the largest saturated injectors currently available:

Also make sure you order some wire clips if you are OBD-2.

 

thank you sir

 

Correct me if I'm wrong, but on the import parts web sit for the injectors it said 94+ accords. My 99" accord has high imp. injectors factory (13-15 ohms). The injectors you showed were low imp. wouldn't you have to use resistors or a resistor box for them to work correctly? By the way I"m getting ready to install 780cc percision injectors which are low imp. thanks

 

Yea you will require a resistor box to run low resistance injectors in your 99 Accord. But the 650cc and 750cc injectors I listed are high resistance (saturated) injectors.

 

Thanks for clearing that up. Sorry I must have missed that part about them being high imp.

 

 

what exactly is a resistor box? I've seen them but what does it do and when do you need it?

 

any answers?

 

So are their any advantages to running a peak&hold injector over a saturated type?

Also are the RC injectors disc,pintle,or ball&seat?
