s13 sr20det corrected injector??

[Arcedaboss]

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....

Pull them out..flow test them....then ull know for sure

Stock Sr20 injectors are PURPLE!!! Not red....
You have incorrect injectors

lol that happened once on a sr20 we bought. someone had swapped out the stock sr20 injectors for KA injectors. Sneaky sneaky.

[jedi03]

and then they sold them for 100 lol...I think some of the stock side feeds in other models is the same flow rate, but I don't recall which off the top of my head...I have some 550 sidefeeds if you wna upgrade while you are swapping them!

yeah stock sr20 are 370.
vg30 are 370 also.
theres a certain year q45 that are 370cc also, iirc.

+1
370cc is stock and they are purple or sunfaded grey purple.
and why is because they sell for 100$ a set easy

Yup found the corrected ones

[Arcedaboss]

So found out that the red ka24de injectors were leaking, which caused my motor to hydro lock..
I took out all the fuel from the cylinders and did an oil change. And got the correct 370cc injectors
Now my car wont start at all. I have fuel compression and spark..
Only thing is that I kinda have weak spark on all coils..
Does the ignitor give out alot on these?

if you have fuel, compression, and spark, then your timing must be off.
FAST
Fuel
Air
Spark
Timing.

This is the recipe. If you have 3 of those things, then the math says you must be missing the 4th.

When ignitors go bad, they tend to fail completely. I haven't seen a "weak" one before. They're either good or they're bad.

did you reconnect ground on the back of the head? tends to be easily missed regularly...is part of the coil pack wire harness
