Hey all,
I have used a set of these with a Horsham chip and they do work fine.
No blown motor, ECU, etc...
There's a guy on here called Ian Parkes and he has some pictures.
The set we played with were used on his car with one of your chips. (3a I think).
I'll give him a nudge.
could we not just compare a set of each on a flow bench etc looking at the timing and spray pattern.
If they are similar we should be ok. Looking forward to an update on this!
Its not quite as simple as that - its the opening / closing times that seem to make a big difference. And the fact that Nismo 555cc/min injectors don't seem to flow 555cc/min at the std S14 fuel pressure.
If anyone has a source of cheaper injectors (that aren't modified OEM parts) then let me know and I'll see what I can do
Did you ever find out about the jecs injectors jez?
1998 Nissan 200sx s14a , 2000 std 5 speed with nismo supercoppermix clutch bn6 Sapphire Blue
And on the injector question will sard 550ccs work with your maps??
JECS was a joint venture set up in the 70s between Nissan and Bosch and they manufacture (mostly) OEM parts for Nissan - Injectors, ECUs and EFi systems.
Most of their parts are made in China now to reduce costs - This was demanded by Nissan.
You might find that they make the Nismo ones under licence for Nissan although I can't find evidence to prove (or disprove) this.
JECS 550s are Red, where Nismos are purple IIRC.
Don't know if any of this helps.
IIRC Nismo 555 injectors for the SR20DET are yellow...
I had a HKS and were yellow too, the salesperson assured me that had the same lag time that NISMO, fit correctly with stage 2a, afr ok...
tomei also has same lag time
but hks and tomei are also expensive!!
no, I revived the discussion on the compatibility with EPROM H-dev and 555cc injectors JECS
ok thank ;-)
