I always get this backwards, but I believe the WRX's were side feed and the STi's were top feed.

USDM Speaking:

Smallest WRX injectors are going to be the factory 02-05 wrx injectors. They came on the EJ205 2.0L. They flowed around 420cc IIRC.

Biggest side feed wrx injector would be the 06 blue tops found on 06+ EJ255 2.5L's. They flow 550-575cc's IIRC.

You can always play around with fuel pressure and injector duty cycle too.

I'm unsure of the arrangment of the NA 2.5L Subaru's or injector size. May be smaller.

Well the wrx came stock in 02-05 with 22x hp and those injectors. I'm sure you can run lower power levels than that with those injectors and just account for it in the EM.

What motor are these goin on?

You're right, you always get it backwards:rotfl:

ALL USDM WRX are topfeed.

Only 04-06 STi's are Sidefeed. 07 STI's are topfeed.

All other turbo Subaru's from 02 & up are topfeed as well.

generally the lower the duty cycle the less stress you put on them. which is why you need to upgrade them... so for you, running 450cc or so injectors for 200hp would simply mean you are running them at about 50% duty cycle or so which is never a bad thing, theyll prolly last forever. on the upper end of those however, ive got a freind running a wrx on the stock turbo and stock injectors with around 280-290 hp and hes at 95% duty cycle at redline, and he hardly takes it to redline because of it....
