hey all, im trying to find the best spraying injector around the 6-700cc/min range?

must be a single cone.

high or low impedance

siemans deka? rochester? bosch ev14 ???

any first hand experiance?

cheeres.

Injector Dynamics...they certainly have me impressed. They make a 750cc item that would suit you nicely...we recently put some 1000's in a stock GTR and the fuel delivery was spot on...afr's were rock solid at idle even with varying inlet temps.

have a good read of their website Dave and let us know what you think.

I don't know exactly know what ID do to them but from what I read they are a late model higher plessure injector intended for returnless EFI systems .

The moving part inside the injector is much smaller and lighter than older types so easier to control at small and large pulse widths .

ID are supposed to got to a lot of trouble to match sets to ensure uniformity .

Google Injector Dynamic and search here under EV14 Injectors .

are these the high impedance 1000cc ? would they work with a rb25 power fc without a resistor? what psi are they rated at 1000cc

edit found this chart

cool. but when i can get brand new deka 4's for 40usd each its hard not to take notice. not a fan of "customised" injectors. i just dont know if there is better. spray pattern wise.

ps. does anyone know where i can find technical product sheets for these said deka 4 injectors? (60lb/hr) long series.

there not as such "customised" more matched so you shouldn't have to trim individual cylinders more that a couple of % there also batched so if you have an injector fail you can order another injector of the same batch

also they have a youtube vid of running id2000's in a NA integra there said to idle well

the twin turbo V8 boy are using them too as you can run big pressure to the injectors the 2000cc can run to 3710cc with 130psi to them

i believe they match them by the duty cycles

7000revs 80%

60%

40%

20%

6000revs 80%

60%

40%

and so on

and different voltages

exacly. im running a 12 injector setup. (2 per port shooting at each valve) rather than bashing anywhere all over the port wall.(ie stock)

havent decided whether to have them staged or running in parralell.

i got the idea from nissans new system

also some sucessful race engines ie: s2 quattro pikes peak

funny. still used in the pre diesel r8 lemans cars... meaning the inlet manifold design and 2 injectors per port.. (before fsi injection)

most of the f1 turbos and most of the current wrc inline 4 rally cars. cosworth,scoda etc etc.

    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
    • From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
    • That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
    • I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.
    • If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
