Rb26 1000Cc Injectors With E85

Recommended Posts

What seems to be the max safe power limit of 1000cc injectors with e85 on a rb26?

Running stock rail pressure (stock fuel reg.)

It's weird cos some results show well over 400rwkw, others only mid to high 300kws

I know you won't be able to tell exactly how much, but are they good enough for around 380-400rwkw ?

As long as your fuel pump is up to scratch, 400rwkw is just under safe limits for E85 on 1000cc injectors.

Easiest way to work it out is this: (keep in mind that this is factoring in all variables and should be considered as a safe estimate)

E85 -

Total cc's / 11 = whp (eg. 1000cc x 6 injectors = 6000cc / 11 = 545hp)

Pump 98 -

Total cc's / 8 = whp (eg. 1000cc x 6 injectors = 6000cc / 8 = 750hp)

wont have an issue, they seem to be a good thing so far, used around 20-25 without issue. Nice and easy to fit dual intank in a GTR too for 500

+ kw setups.

seems like im on the right path....

a mate has some "bosch indy white" 1600cc injectors, they are low impedance/11mm top o-ring so should be direct fit, are they worth grabbing ?? his willing to give em to me for pretty cheap (of coarse im going to get them ultrasonicaly cleaned and flow tested before install plus new o-rings)

My injectors are id1000's, tuned on e85 and running 75% duty and only 20kw off for 400. They still got some room in them. This is also on a nismo pump

Indy blue and whites are rubbish to tune with. I really don't think people know just how good the latest ev14 style injectors are. I wouldn't consider anything else if your looking at 1000's or above.

Anything to do with them been high impedance? Instead of low?

Poor latency...... They are old and slow.

You can mask the crapness by running them rich. But you can never hide the crapness completely.

Poor linearity for the pulse times you will need to run, bad dynamic control, poor atomization when compared to the ev14 injectors.

Ok thanks for the replys guys, realy helped me, lucky I didn't rush to buy these antique injectors lol

Are all EV14 bosch injectors high impedance?

We have had some issues with the bosch EV14s lately and I know a big name shop who also has a box of dead ones they've pulled from a number of cars.

They've cost me an engine and almost lost a race engine for the other shop.

Shit that's not good ! What went wrong with them? Old batch of injectors or design fault?

Were they cleaned and flowed before use?

Old ones were fine, most recent batch seem to work when they feel like it and lose random amounts of flow at random times.

Don't know what causes it, haven't really looked too far into it yet.

Were they cleaned and flowed before use?

We only buy matched sets with flow reports.

All the failures were with brand new units.
