i was woundering if 550cc or 480cc will drop right in the stock sr20det fuel rail. are GReddy 550CC Top Feed Peak Hold Universal Fuel Injector good for the sr20det or should i go with the 660c or 720cc, also will these drop right in. i could get the greddy 550cc, 660cc and 720cc for the same price so i dont know which one is better. if u guys can help me out with that, i want to make more hp. like 300-400 hp.

also i was also woundering if the 440cc topfeed injectors for nissan sentra SE-R will fit right in the stock sr20det fuel rail, i know that the se-r has a sr20de.

also would the OEM STOCK SUBARU WRX STI FUEL INJECTOR fit in the sr. i heard something about it, like some1 used them but wasnt sure, does any one know what size they are. lmk thanks
