Hello I am having a few problems. I am running a built H23 motor and it has 370cc injectors but it dont run very good. rich!
It has 12:1 lots of head work, cams, rods pretty much a fully build would I be better off tryin my factory injectors? What size are they, also will they work better?
It is a 92 SI 4WS 2.3.
Thank you !

I am also running a fuel controller. Apex-i S-AFC

 

I have a similar setup and i am running stock vtec injectors (345cc) with no problem.It ran rich at first throwing a code but we turned down the fuel a little on the safc and no problems since.Waiting on dyno time to fine tune.

 

The H23 injectors are 245cc, same as the B series. The H22A1 injectors are 345cc while the A4 injectors are 290cc.

 

so I would not want to run my factory injectors right?
So what I make out of it I need somthing right around a 310cc?
Thank you

 

yeah 370's may be a bit much for your setup but why dont you try and tune the safc first... got an adjustable fpr?

Yes I have a fpr , I had them tune it with them 370's but he said to get them out of there?
Fuel psi. is set at 35 ?
I would like it to run better then it does, and if I open the header at the track it gets to rich and starts to pop all the way down so I have to lean it out?
I dont really know what to do ?
Thank you
