how much bigger and how much more flow does the type r fuel injector have over the gsr fuel injector?

 

B/D series use 240cc injectors.

 

ITR injector actually runs slightly higher CC. Not sure on exact figures. However it is still lower than the H22A injectors.

 

ITR runs 240cc injectors. not sure about fuel pressures. too lazy to look in Helms. however, they are the same for B and D series engines, so 240cc is 240cc.

 

240, same part number

 

They are pretty much all 240cc, honda just varies fuel pressure to change the flow rate.

 

but h22a actually do have higher flow rate injecter its like the only one that i know of that do but there a thread with a list of all honda here

 

All B/D injectors are 240cc, maybe even F series too.

I think the H22A is 270cc or 290cc

 

Correction. All D series VTEC injectors are 240CC. Non VTEC and VTEC-E D series injectors are 190 CC. In other words, D16Z6 and it's JDM variations, D16Y8 and it's JDM variations are 240CC. All others are 190CC.

Integra RS, LS, GS, GSR, ITR injectors are the same within the same OBD generation.
