yes no question. I'm hearing that the gsr/itr has different pressure

 

I'm not sure about d series but all b series are 240 cc's if 'm right.

 

VEHICLE Injector Types Flow Rate
1988-91 Civic si/crx si Peak and hold 240cc
1992-95 Civic si/ex Saturated 240cc
1996-00 Civic Saturated 240cc
1990-91 Integra Peak and hold 240cc
1992-00 Integra ls/gsr/type R Saturated 240cc
1992-96 Prelude non-vtec Peak and hold 240cc

Good info Thanks!

 

im pretty sure that all D series are only 10cc's smaller than B so i would say they are all 230

 

I tried running 96 dx OBD2 injectors on my D16Y7/92 LX running OBD1 and the car ran like ***. It would stumble and backfire at times. I read that even though the injectors are the same size, the resistance is different between OBD1 and OBD2 even though they are both D series injectors.

 

most D-series injectors are 240cc. (some are 180cc)
most B-series injectors are 240cc. (a few are not)

different engine requirements are handled through pressure regulation differences.
Mush easier and cheaper for a manufacturer to do it this way.

 

i know all d-series injectors are 240cc expect for d16y7 they are 190cc. Also as far as i know all b-series injectors are 240cc too. H-series are 3xx.
