Yes I kno there are plenty of threads out there that people post this info. I have seen people say OBD1 jdm h22 injectors are 310cc and sum say 345cc. Well I need the exact answer, please if u are not sure, please Dnt post here.

Question: 1. what CC are jdm obd1 h22 injectors
2. What CC are jdm obd2 h22 injectors

any help is highly appreciated

 

guess no1 knows anything about h22s?

 

obd1: 345 cc

 

From my information:
1. 345cc
2. 275cc

 

345 obd1 peak and hold type
290 obd2 saturated type.

I forget where the info comes from. Maybe the service manual. Its in the Prelude forum.

 

if i used RC 310s instead of the 345cc OEM will it make a diffrence in performance. i will be getting a base map for the RCs

 

What type of injector? And what ECU will you be using to run these injectors?
