Hey guys, I am wondering if I will need bigger injectors with the setup I will be running soon. Stock s5 t2 with turbo back exhaust, fmic, intake, bov, and a megasquirt stand alone. Will I need bigger injectors with my setup?

 

maybe not need, but without a doubt you'll probably WANT them. and if you do go with bigger injectors you'll most likely need to upgrade your fuel pump as well to keep up with the greater output of the injectors.

 

Yes. You will want to upgrade the fuel pump, as well as move to 720CC secondaries.

 

if you're going to run over stock boost levels...then yes, get bigger injectors AND fuel pump....if you're going to do the appropriate mods to keep the boost down to stock from adding that free-flowing exhaust, then you could get away with the stock ones. I'm guessing you want to up the boost tho...so yea...get bigger injectors and fuel pump.

 

My friend ran 10PSI on stock injectors with a haltech at 11.2:1 A/F on a streetport.

You probably don't need it, but it would help if you want to upgrade sometime soon.
