Mate at work has one and wanted to upgrade the power a little,so fitted a front entry td05 instead of the td04,sti intercooler and decatted the exhaust.... had zen do a ecutek remap and said the standard 500cc injectors would be fine... i thought they would be different too,but apparently not.

51wrx Will have 440 cc Standard, good for around 300-320 bhp with standard fuel pressure.

Most people opt for the Sti pink injectors as an upgrade for the WRX, they are approx 550 cc and can flow enough fuel for 360-380 bhp with standard fuel pressure. (would need lots of other mods to get this though)

Possible, was an assumption on my part on how much power you can make with the standard injectors.
