that one is defs a 2.8, asking for ya boi vims see if there is a graph for a 6870 on a 26

Think it made over 800rwhp for about 3000rpm which is just silly!

Not sure on a 2.6L, it would shit out power but be fairly laggy. Doesn't vims want a track car?

The 6262 sillyness is never ending... New cams just got the most power and torque it's ever made

Dale is 100% correct its a well proven fact that smaller cams in RB's aid in response. Even going from a stock cam to a type b pon cam will cost you response. Been many track guys that have thrown the

Id agree with that, some good results happening on 3.0L and 3.2 stroker kits with the 6870 from what im seeing around.

Could be OK for a 2.6 if a small enough rear housing is selected, but it would be a issue up top end when at song. (depending on how hard you pushed it)

Very very nice mate must come on song strong !

6466 is still my fav turbo, seen results range from 500- to over 600kw

No need for dirty big 6870's and 7175's etc

Haven't got it back yet. Imagine it would push towards 600 with another 3-5psi like other results I've seen.

Definitely a good choice for E85.

Do you have a dyno graph or 38psi 2nismo?

I saw a dyno result of a 6870 on a 2.6 today with cams, low 30ish boost, make mid 500'sKw, was as laggy as hell, not very impressed, looked like a slug to drive on the street, nothing then all.

Seen a few like this so far on 2.6's, seems like the 6870 is more towards the extra 15% capacity that a 3.0L or stroker delivers.

Looks like 2.6's run a larger area under the curve on the 6466....

It's a 1100hp turbo on a 2.6L, it was never going to be responsive. I would say my 6262 is right in the sweet spot for a 2.6L non drag application but it's rated at 705hp.

6466 would be a good all rounder for a 2.8L and a 6870 isn't too bad from what I have seen but more towards a drag power band.

I completely agree, 6262 or BW EFR 8374 is the biggest I would go on a real streetcar, up to 3.0L. I wonder how far off the compressor maps the 2.6 is with some of these giants? And I guess I will keep wondering because Precision doesn't need no stinkin' compressor maps!

No point until it has enough injector. Then you'll see the whole thing. Ethanol and a torque converter fill the hole that might otherwise be there with a petrol/manual.

      Find out what RPM it was idling at with the IACV unplugged. It's very weird that the rpm didn't change at all, and then it stalled. When it stalls is it nearly like a switch off, like you've turned the engine off? Or is it more stutters and sputters and coughs to death over a few seconds? Or does the RPM just slowly keep going down and down? Have you done a test of trying to start it with the AFM unplugged? Does it still die?     If you Follow Josh's advice on using Nistune to check the voltages (which is a perfect method!) if you see anything out of wack voltage wise, THEN get the multimeter out and read the voltage directly at the sensor. If the two vary, then you're now looking for a wiring issue vs a sensor issue. So be aware, what the ECU sees, may not be what the sensor is actually saying too...

      RB25DE NEO with Haltech ECU

      By MBS206 · Posted

      You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.
