Odd, I ran a freddy manifold on my RB25 with a GT3076 at 18psi.

RB25 - 314rwkw 750nm torque

RB25/30 - 320rwkw / 850nm torque

Ahhh, just read that you have a RB20. Surely that won't make too much of a difference?

no im running a stock rb25 motor with arp head studs camtech 272 cams. yeah not sure, might be dyno who knows. its never seen that kind of nm. similar setup cept plazaman gt3076 .82 and e85 made just under 600nm on same dyno. who knows. see how it goes at drag day in september. should trap ok mph im hoping. the cams are suited for a larger rev range, i only go to 7200. these might make more torque over that,but stock motor , keep it at 7200 so it stays together

Definitely something wrong with that torque reading. Mine was done on two different dynos, and same reading.

So don't lose faith in your freddy manifold just yet. You'll find that is not the problem.

Power is up there - just the torque is not quite right. MPH will definitely be an indication of what you're really running.

Good luck!

I'd imagine you are talking about a dyno dyanmics torque reading (tractive effort)? You can't compare that to a dynapack...

Mine made 590nm on similar power so methz result is just about spot on

Mine was one dyno dynamics, and the other was a mainline, both had similar readings

Hey guys flicked through this thread but just chasing info...

Had a kando on the Sr and now picked up a pooline. Just wondering whether the 4inch covers on the td06 25g fit low mounted. Aside from a spacer plate and extended studs I'm wondering if they foul on a stock rb25 manifold anywhere. I know the 3inch fits indefinitely but I already have some cooked Chinese low mount unit on there now with a 4inch pipe that I'd like to reuse if possible. Cheers

Thread revival.

I've been away from skylines for far too long and I'm coming back. Looking at these turbos again and can see they have the new bolt on internal gate versions with the adjustible gate.

Are there still boost issues if running Internal? Td06sl2-20g in 8cm for response and direct bolt on.

Mods: 550cc nismos, z32, nistune, other usual bolt ons.

Any input would be good. Or am I better off going hyper gear?

Chasing 250-279

Hypergear internally gated Rb turbos are definitely better, and so's externally gated. check out other member's results in their thread.

I disagree. Kandos are the next best thing to precision and garett. So cheap, and well built.

just proof there i've been away for too long, i called the actuator - 'gate'

hmm ok 10cm internal gate, any dyno sheets with stable boost? looking to run 18~ psi on unopened RB25DET.

I'm posting this to save you some money. This is a kando TD06 in a 10CM turbine, notice the boost creep and tapper.

and I have received many of turbine housings of this kind to re-work on its internal gate. From the way of how the turbine housing is cast, internal gate can not be effectively enlarged either.

Depending on how much power you are targeting. our STD high flows in most of cases can reach your goal with better performance and longevity.

21U STD high flow, E85 fuel.

Perfect boost control. Internally gated.

Thanks Tao, i've been in contact you on FB via PM about the hiflow as it looks to be the way to go

unless there is other evidence and feedback with the int gate with kando, will be going hypergear. i had their ext gate setup and it was great. but want to keep it all factory looking now

Cheers

Anyone had a turbo highflowed with one of the kinugawa GTX compressor wheels? I have a pair of -5's that i wouldn't mind cramming GTX67 wheels into.

    • The incentives are mostly the same, yes. Ethanol is cheap compared to the cost of doing 98-100 RON with crude oil alone. 87 to 93-94 AKI all with E10. In 2020 Canada mandated E10 as a part of their "renewable fuel standard" and is supposedly going to go to E15 in 2030. In California where there are only 8 refineries with two threatening to shut down next year it's been over 20 years now of E10 and 91 AKI maximum because there's just not enough refinery capacity or crude oil supply relative to the demand for premium unleaded fuel. And CARB's low carbon fuel standard means functionally none of the diesel available at the pump is made from crude oil anymore. It's almost all entirely 20% biodiesel blended with 80% renewable diesel (hydrotreated vegetable oil) now. The number of gasoline vehicles that support E15 or higher ethanol concentrations is surprisingly low, I can't imagine it being wise to play tricks like this without flex fuel sensors in most of the fleet.
    • It's almost certainly the same as the one next to it.

    • South Australia, which is hardly as far behind as the rest pf Oz makes out, and who is also not a paragon of progressiveness (read that as over-legislation) in the area of vehicle standards, has this to say on the subject: Adjustable coil-over suspension Aftermarket adjustable coil-over suspension components are suspension units that incorporate an external thread on the main body and corresponding threaded spring saddle that allows the vehicle's suspension height to be varied. If fitting aftermarket or coil-over suspension components you must submit an Application to modify a light motor vehicle form and a report from a light vehicle engineering signatory (LVES).
    • Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers
    • Those above shitboxes, mediocre and above usually have a turbo strapped to them, hence the slightly higher octane is required.
