Hey, I have a 98 JDM h22a in a 96 accord. I will be running a 100hp shot direct port NX next spring (currently 50hp single), will I need to upgrade my injectors to prevent from going lean? I have no fuel modifications so far, just ignition. I have the walbro 255lph intank pump and B&M fpr and fuel pressure guage waiting to go in also. What are the stock injector size and what size do I need (if I need it)? I have a V-AFC too, but I dont want to go so big that my ecu will go crazy. What about the dsm injectors I hear about?

Thanks

 

I think stock injectors in an H22 are 310 or 370cc...i'm not sure tho, but someone on this site will know for sure. Injectors will be a good idea, your stock ones will probably be running at 100%, full duty, and u might go lean...

 

96+ are 290cc

 

nope. 97+ H22a4 are 290cc.

The 96 is an H22a1 and has the regular 310-345cc injectors.

 

So what should I go up to? How much can I go up before it messes with my ecu?

 

you are correct
