Does anyone know the specifications of the following injectors?
1997 7AFE (1.8L) injectors:
* impedence = ?
* what cc are these?
1988-92 7MGE non-turbo supra injectors:
* impedence = ?
* are these 320cc?
thanks!

7AFE
95cc/min, 13.8 ohms.
7MGE
150cc/min, ??? ohms

Forgive me for my ignorance, but is "cc" short for cubic centimeters? and in the context of injectors cubic centimeters per minute? Im assuming this would be at a given fuel pressure tho right? Say 36psi maybe?
I was informed that the 7MGE injectors were 320cc injectors? 4AGE red tops use about 200cc injectors right? I know that CD5A mitsi lancer GSR ones are 390cc and RB20DET ones are about 260-280cc perhaps we refer to them differently here in NZ? or are the 7AFE ones really that small!?!
(slightly confused).

Wicked - thanks for that information. I think I will put that "injector testing" information to good use

watch out though...
86-87 7mge's run low impedance 3.x ohm (yellow) injectors...
88-91 7mge's run high impedance 13.8 ohm (?colour?) injectors...
both flow ~285cc/min (where'd you get that 150 figure from??)
flow rates for the two are basically the same, though they are specified different - but at different test pressures.

Either way, easy enough to measure the resistance.

The last engine I built, I did some investigation work, I lined up the following list, and had them clean and flowed on a professional flow bench (Vane Autocraft Injector flow bench), all figures are at 300Kpa (44Psi), so naturally more pressure more flow in theory:
22RE- 92cc/min
4AGE 100Kw- 95cc/min
7AFE -94.4cc/min
7MGE - 150cc/min
4AGZE- 200cc/min
The 7M I have are green and are 13.8 ohm's... I checked them last night. the 7AFTE that was available here had a were purple, but I wouldn't know the flow rates.
