Hi all,
Are ca18de and det injectors the same?
i have a set of ca18de injectors, and want to know if they have diff flow rates...
Cheers, Dane..

size is usually a fairly obvious clue... try talking to Dr. Drift or something, they are fairly switched on with all things nissan. my mate who built an Rb30DET (Rb25 head) used their advice quite a bit.
you could try to measure the impedance of the injectors, usually the higher performance the injector the lower impedance (resistance).
logic would tell you that the DET ones would be bigger, but you just don't you sometimes do you...

DE ones are definitely smaller

I know that the ca18det ones are 370cc low impedance. Have know idea what the de ones would be but im sure there smaller. You can try and look them up by part # on this web site. http://users.erols.com/srweiss/tableifc.htm

definitely not the same.
Impedence gives no indication of flow rate.
With CA18: red ones are DE and white ones are DET.
The DET ones need dropping resistor.
Probably can't use DE injectors on any boost higher than 5 psi.
You would definitely need a remap to make the DE injectors work with the DET, and it would be far cheaper to get DET injectors.
otherwise...you can put a nominal pressure 35psi? on the injector and apply a 12v voltage for 10 seconds, and multiply the fuel volume by 6. REMEMBER to use dropping resistor if checking DET injectors.
EASIEST way is to write down the numbers on the side of the injectors, and run them through google.
