4Th gen with a 92 h22a with skunk2 70mm IM and TB try-y headers 3inch cold air 2.5 inch exhaust i want to upgrade to rc injectors but idk what cc's i should get oem is 310's ? Would 550 be right ? Opinions pls

 

i think you'd be fine with the OEM's really, haven't done anything to crazy and i think the OEM's are good up to like 300hp? correct me if i'm wrong

 

You could do the fuel pump power relay and/or a walbro 255 to ensure you are getting the most fuel possible to the stock injectors.

Your money is better spent in tuning what you have to know where you are fuel-wise.

Pick up a chipped ECU from Tony at HandCommand and go tune, figure out where to go from there.

 

Well i do want to get tuned but i have bad injectors and i wanted to upgrade to some rc just didnt kno what size would be ok i need them to be peak and hold not saturating

 

u can buy any aftermarket injectors, if u don't planning turbo engine at this moment
even 550cc will be more than enough.

 

Might be worth looking into RDX 410cc's, check them out at rosko racing.

 

RDX ftw. Some badass injectors. Got some coming for my hatch as well as an rdx rail through rosko. Ive got some stock injectors. 50 shipped and they are yours.

 

Fashoo sounds all good I'm going to think bout it. Really appreciate it

 

rdx is best choice. remember that you have to purchase a different rail to use them. it you can get from rosko racing.

I would for sure get a walboro installed and tune done. all the changes can cause more problems in the long run if not tuned for it

 

you really don't need larger than the 345s that come with the h22 when running N/A do you??

 

Not until you get pretty far into the engine. Currently I am running the JDM 345s on my H23vtec that has 11.6:1 compression and PRO1 cams. I am a bit over my comfort with them, so I have a set of big boys to go in, but won't be running the car hard until next summer anyways.

 

Ok so i got few questions u guys can clarify for me
1) usdm vs jdm oem injectors for the h22 are they the same ? I keep hearing its 310cc v and 340's?
2) i just ordered a walbro 255 pump just to be safe but my main question is if i went with 550cc injectors from rc will it work still i am getting tuned btw
