S1 And S2 Injectors

[bluboy]

Hey guys,

The injectors in my s1 rb25det seem to be leaking and I have a good set from a s2.

Are the s2 injectors the same size, plug and volume as the s1?

dont remember the size of the r33 injectors, but from what i remember the s1 and s2 injectors were the same, both side feed. or get some s15 injectors if you want extra headroom only the rb26 and rb25 neo had the top feed injectors

stock turbo injectors are 370cc and i'm pretty sure both S1 and S2 are exactly the same

No worries, thanks guys much appreciated.

And what do you mean by headroom? Are you saying that larger injectors can be run on a stock setup and tune? I realise a new tune would be needed to use them to there full potential but would it run rich on a stock tune?

it would run rich, not by an abnormal margin, but a little, from what i remember doing on my older fuel injected cars, when putting a couple bigger injectors in, i ran the fuel pressure a bit lower so if 3 bar, i ran them at 2.8bar. car ran fine, and when taken apart, it was in perfect condition, but never got it tuned to know exactly what was going on.

but this was from 240cc-> 320cc injectors
