Sadly I'm gunna be a negative Nancy on this 1. Sounds like it was in 3rd gear for a kick off lol 780hp at 99mph. The run was barely a few seconds long. (Which could be operator getting scared of it jumping outta the dyno) so possibly a + not a - there... 

Also it's on a dynojet so you can literally pull 15% off those numbers "for straya dyno figures" so 780hp is more like 660whp on our shores. So it's a sub 500rwkw result from a set of 985kw snails?

Would love to know what fuel and boost that was on!

And to add to the bullshit, it's on a VR38 not a VQ hahah so yeh, not so great...

Surprised it hasn't been mentioned yet, but the original post that video is from specifically mentions that it's during tuning - ie, that's not a full power run.  I'm not sure why they didn't show an "all in" run, or say what the final power was but the implication from the guy whose car it is has very much been that this isn't the power it's capable of.

Interesting..... Wonder why the secrecy? Kind of a bit dumb to post a vid like that then hide the results? 

Maybe it's a Skola tune? ?

Yeah good point, would be great to know what boost, fuel and gear that run was done with and a look at the graph with rpm.. hopefully we'll start to see more results with that crucial info soon.

Meh... buy a G series and still get clouted by the whole EFR crew.'

you guys go right ahead 

I stuck up for it and am pretty much the ambassador for EFRs here lol

Looking through the various Instagram comments; G25-660's 0.72AR, VP Racing Fuel, AMS Alpha 4.0L BC stroker VQ, high comp JE Pistons, nitrous, Motec M150.

812rwhp and 676rwtq @ 22psi

According to Garretts cattledog there are or will be T4 twin scroll integral gate turbine housings available for the G series .

If you buy or make a twin entry T3 to T4 adapter plate you may get one on a Skyline manifold .

If Garrett are smart they'll make T3 flanged housings available , like EFR did .

Still no one has put this on a RB26 in a twin setup?

I wouldn't hold my breath, I certainly haven't heard any hints of anyone doing such a build and given they won't realistically be bolt on options I'd say most would go for known and easier/cheaper to fit combinations.  

There are VERY few dyno results out the for the G25s, and so far I've seen nothing worth really writing home about.  The most indicative of any potential I've seen is an EJ25 powered Subaru with a .72a/r G25-660 on it putting down a bit over 500whp (~370wkw) on a Mainline roller dyno at 26psi with full boost coming in in the mid/low 4000rpm range.    It's decent, but nothing to put the EFRs on notice.

True that Im wishfully thinking this may come out this year before I bite the bullet for EFR

They are out, just doesn't seem like a lot of people have tried them - or at least boasted about their results so far.  It's probably too early to draw any conclusions one way or another from what little info is out there, it feels like there is potential there.

The odds are there are a lot of people like you, who are interested and thinking about it but want someone else to try it first - which is very reasonable... but also means there is probably not much point holding your breath.

The "next size up" G-series are likely to be more interesting to everyone, it was an interesting choice going for the baby size first.

Looks like the Integrated Motorsport Time Attack R34 GTR is going to twin Garrett new series turbos from a single EFR (9180 from memory) shall be interesting to see the differences, obviously custom everything, manifolds etc....

    • I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps  
    • According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car. 
    • It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
    • If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
    • Lock me in mate, although I'm not sure if I'll be heading up from Goulburn or down from Sydney, either way, return will be back to Goulburn
