Just curious to know how to tell apart from 310cc and 340cc OBD1 H22a fuel injectors. Hondata states that the OBD1 H22a injectors are either 310cc or 340cc. How do i know which of the two i have? Is there a way to measure the ohms and tell or is there some kind of numbering on the fuel injectors? Is it true that there are two different type injectors for the OBD1 H22a, or does the injector size have any relation to whether it is a USDM or JDM engine?

Thanks,
Mark

 

I've never heard of 340cc injectors on a stock H22a... US, JDM, or otherwise... They are all 310cc AFAIK.

Actually I've never heard of stock 310's on a Prelude. The flow rate charts that people get back from RC's cleaning service shows 330cc to 340cc flow rates for the OBDI low impedence injectors and around 290 for the OBDII high resistance injectors.

 

I got mine back from RC about two weeks ago and they all came up flowing 340cc-345cc. As far as I know I have never heard of any other flowrating for the OBDI injectors, the only difference are the OBDII injectors which flow 290cc.
