Injector size on "old" wagon
Hi,
I have just got my hands on an 94 GT Impreza Wagon. It's an imported from Italy. Does anybody know the injector size on these models?
Thanks

Is there a difference in grey top injectors from JDM cars to exported versions?
All flow reports I have seen (including my own) for the ej20g WRX injectors is 440-450 cc/min, but I think all of those were originally from JDM cars.

no the grey ones are all 380cc but agree they do flow reasonably well and there is not massive difference between them and the yellow 440s fuel flow capacity wise.

These are my results. Stock grey top injectors out of a japanese '95 WRX sedan:
450cc@43 psi = 424cc@38 psi

I'm not the only one in the US that have flow results showing 440+.
The 380 number gets passed around a lot (both in UK and Aus), but have never seen any flow numbers to back them up. So either it's a myth, or there are two variants of the grey injectors.

Not other Subaru injectors, but have personally flowed Toyota 440 and 365 (3sgte and 4agze) at the same facility. RC engineering is top notch, so I say there is zero chance they messed up the numbers. Plus there is at least 2 other guys that I know of with the same injectors that give independent confirmation of 440. Have you seen any flow results showing 380? That would make things interesting.
If you think about it, it makes sense; '95 WRX came with 260hp stock (STi vairant had 276 with the same injectors). That's a bit of a stretch for 380 injectors given the type of fueling margin the factory puts in.

ahhh, right, now im stumped, i thought from the last time i looked, they were grey, but i cant be 100% certain on that, im just gonna have to check when the car comes back.
if there is no major difference between the grey and yellow injectors, what would be the next stage up, is it the reds at 550cc??

haha ok, then let's say they should be grey "mystery" injectors.
Really, does anybody know where the 380 number originated? What is the part number for the grey tops as listed for the UK version? I might be able to get a part# from the JDM parts CD.

These are the part numbers out of the Japanese parts CD for the EJ20G WRXs; sedan, wagon, STi, etc are all the same.
16611AA100 superceded by 16611AA101
Are these different than what is in the UK parts catalog?
