Default How to Calc Injector Flow??

Just wondering how i would see how much my stock Justy Injectors flow??

i'm trying to figure out if even throwing in a set of Stock 2.5 Injectors will do the trick.

BTW...my justy is Turbocharged, running 8.5 PSI of boost!

I'm trying to figure out if i should toss some injectors in it...or play with a RRFPR

you can use this utility I have been playing around with to see exactly what size injectors you will need. If you need to know what your OEM injectors will flow, call up the nearest subaru dealership and ask, they should be able to dig that info up. and avoid RRFPR's like the plague, I know I'm going to catch flak for saying it, but they are REALLY bad things. Your justy injectors probably flow better than stock 2.5rs injectors. Keep in mind you will need to use some form of computer trick if you move to any larger injectors. apexi S-AFC's are getting really cheap second hand ($150 or so) and work quite well when moving to larger injectors and higher boost levels.
