600hp, 3040

Which can make really good power on an RB30DET - it will crack 300kw without stress, but its probably worth knowing that a GT3582R will feel no different on an RB30, but make quite a bit more power again :O

VB- Seemed to be under the impression it was a far smaller turbo than it is.

bingo! was getting confused with the 3071/6, well was thinking of those, didnt realise the 30/40 was that much bigger. lol my bad guys

Its no RB20...

Thank God! :)

But is a very nice setup. Was simply blown away by the throttle response and urgency from low revs. Very, very, very nice setup. Looking at the power delivery i understand why the one timed you opened the taps i did almost shit myself :D The power just keeps climbing and climbingh and you can feel that from the seat of the pants. It not only pulls nicely in the top, you can feel it is making even more power up there

Just came back from a 5-6hr drive with Brisby; completed 270 running-in km on the first night :thumbsup:

Damn it felt awesome!! So farken happy!!

Here is the latest run-in tune:

Hey Al what turbo are you running, i cant find your engine specs in the rb30 dyno thread?

thats great results for a 3076r on 16psi (i think thats what the dyno graph says?), any ideas what the turbo is capable on pump fuel and around 20-22psi? might be something i will put on my new rb30det setup as im only gonna be chasing low 400hp mark or so on stock internals and aiming for response more than anything.

I think quite a few people are watching with interest to see where it can make it to. The way it levels off up high suggests to me it might start struggling to pass 320kw.

With good fuel the gt3076's have cracked 340rwkw.

The Gt3040 with good fuel has cracked 360rwkw but bugger all more.

The gt3040 vs gt3076 on pump fuel the gt3076 wins as its more responsive, linear and is slightly less laggy. With E85 around the corner the gt3040 may be a better option.

I just don't like the way the gt3040's come on boost compared to the gt3076 and gt3540's. But thats just me...

GT40 +E85 +rb30det ftw. :D

    • Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.
    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
