My fuel system is fairly simple, just FMU and bosch inline pump. I'm only running 7 PSI of boost. Right now, the H23A has stock 240cc injectors. I have an FMU with a 12:1 disk. Do you think the 240cc is too small for 7 PSI with that FMU? How about going with bigger injectors?

 

Slap those ones in that we got the other day from the H22a and see if they're bigger. It'll take like 2 minutes.

 

I heard the H22 vtec injectors are 270's.
Somebody correct me if I am wrong.

according to rc engineering the 93-96 prelude h22a vtec peak/hold injectors are rated at 330cc.

the 97-up prelude h22a vtec saturated injectors are rated at 290cc.

that's all according to rc. i think we can trust them on that one though.

 

since your car uses p&h injectors already, just go and buy some stock DSM injectors for like 100-150 bucks from thepartstrader.com...they're rated at 450cc stock.

 

I'm thinking it's not gonna run to good with the 440's.

 

i don't think the stock h23a ecu could handle running 400+cc injectors.
