2jz injectors , what size, what do they fit?

[flygt4]

hav been given 4 2jzgte injectors (what i believe to be). what size are these and do they slot into a 4a?(have been told they do)
ps. hav link etc to run them if they do fit.

if they're JDM they will be 440cc/min (or 430cc, depending on who you ask). US models (and maybe other export models?) are 550cc/min.
Should fit into a 20v side feed fuel rail without problems.

yeah thanks for that. i had read the export ones are 550 high impedance whereas the jdm ones are 440 low impedance?
these do fit directly into the 20v fuel rail , and are a significant increase over whatever is currently in there , judging from the amount of unburnt fuel that comes out the exhaust when slotted in.noone happens to know how to establish whether they are jdm or us ones do they?

Other way around.

The 440's are high and the 550's are low as we has to fit resistors when we put the 550's in.

I presume that you are going to run a turbo or they will be a huge overkill.

yeah am already running a decently sized turbo , the link is tuned for a different smaller turbo so when i get it retuned i may as well throw some decent injectors in too.these ones slot right in so i figure they must be 440cc jdm ones then.should be adequate for my needs

have just had these injectors fitted and am awaiting a tune.. they had to hav resistor packs fitted so am i right in assuming they must be 550's then? if so...cool
