s13 sr20det corrected injector??

I have a run ability issue with my sr20det since day one I swapped it..
It idles like crap and dies.. the throttle body response is super laggy.. breaks up under load..
Once I cover the MAF sensor with almost my whole hand it idles better and it actually goes into boost.
Now this has leads me to the injectors being incorrect size for the stock ecu
Not to sure if this are the correct injectors for my s13 sr20det redtop.


Part number looks like
A46-00 08807219
They are red

I looked them up but they are supposedly for a ka24de or a sr20de
But why would some one do this to a det ??? Want to confirm I have the incorrect injector size

why not check that part number against the manufacturer to check flow size...stock iirc is 370cc, stock ecu can only do so much and tune would be needed to run different sized injector...could be person was being cheap and just put on what they had but dunno....
