I have 440cc injectors on my car and im looking to increase them to 600cc (roughly) because im running high boost (23psi) in a low compression hog port setup (i get low power at low boost; anything below 15psi) but the second my boost go's past 19psi I start leaning no matter how much fuel I try to add, even with my 190lph fuel pump.

I forgot what kind of impendence injectors we use, but I was hoping anyone could direct me to which kind we need.

Thanks

 

just to review your setup... are you doing standalone or piggyback fuel management? i ask this because if you are on a piggyback there is really no point on increasing the injector flow since the MAF/MAP is pretty much maxed out.

injectors... our cars normally (stock ecu) utilize high impedance (12 to 16 Ohms) type... but it does get harder/expensive to get one that is higher than 440cc's. if cost is an issue, you could always use low impedance type which is more common to find them in higher flows and cheaper, but you'll need to use a resistor box to trick the ecu/piggyback.

now, if you are standalone... i believe most fuel management units can accept both types of injectors

I have a custom ecu flash for my ecu for my turbo setup. ill have to adjust my fuel becuase its flashed for 440cc

 

There were some on Ebay I saw that were 60lb instead of the 42lb ones people have been using. I would check those out.
