Default injector type and size questions

I don't know if I am in the correct forum... I am running in a 2002 2.5rs with a usdm sti block with forged internals, stock RS SOHC Heads, Stock RS intake manifold with Perrin topfeed fuelrails, stock topfeed injectors, and a Borla NA header. Eventually I want to turbo the car. Currently I am trying to purchase all supporting fuel mods that will be needed to run the turbo. Will any STI or WRX topfeed injectors fit?

I'm not sure about the fuelrails you have, however, since you are still running your stock injectors, I would think any other top fed inj would work.

If this is the case, go purchase some used stock WRX injectors, uncap them, have them cleaned and flowtested, and you will have about 800-840cc injectors for cheap. This is the setup that I have been running for the past 3 years or so.

Here is more info if you need it : http://forums.nasioc.com/forums/showthread.php?t=478921

I'm running DSM 440 cc low impedence injectors that i got for free. Good up to 280 horses. Though, it cost me $1.50 for resistors and solder. And to answer your question, US spec sti's are side feed and don't fit. Go with the top feed wrx or sti pink injectors.
