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 SS button head cap screw on the back? If so, good to know. I presumed it was there for basic assembly and nothing more. 
    • Hello, everyone. I'm new to the forum. I have a 1989 Nissan Skyline R32 GTR. I have lost all power to the interior, including AC controls, the gauge cluster, turn signals, and windows. Stuff that still works includes the horn, brake lights, radio, and headlights. All fuses, in the interior and exterior boxes, tested good.  It starts and runs fine, just with no gauge power or anything stated above. No warning lights either. Things that I have tested: - Fusable link tested fine - No other fuses blown - Alternator good - IGN switch tested fine - With my power probe, I can backfeed power through the IGN pin to the plug on the back of the gauge cluster, and everything comes back on.    So my theory is something on the control side that sends the ignition power through the system isn't doing its job, or a wire is broken. (I would think that it is the ignition switch that would do that, but who knows?). The ignition relays don't fire (all relays tested good). So what tells them to fire other than the IGN switch?  I would really appreciate it if someone had some insight on this. I have tons of hours into this; I don't want to give up in defeat! I have the HD wiring diagram, but having all those wires laid out like that on one sheet of paper makes things pretty hard to follow.  Thanks for reading, and thanks for the replies.  Where should I look next? Thanks.
    • Install a MAP sensor pre and post throttle. Best data you could have for NA, then play with the bends and/or air box and see how much of inflection is created at WOT on the plot.
    • And gone to a new home  
    • The car remains in paint jail. I am now pretty convinced that the whole "RB25 Airboxes are kinda limiting to ~300kw" could be a thing. Also saw a good video from Engine Masters: (Sorry for FB link) (https://www.facebook.com/watch/?ref=search&v=761771519471924&external_log_id=c10bcbb6-2c39-4ff3-9240-287e9921fde6&q=Cold Air Considerations) Where they tested Pod Filter sizes and kept adding bends to a LS3 on an Engine Dyno to find if bends caused power loss. It's a good video worth watching - They did lose ~25hp from making an intake which had 3x90's and a 120 degree. They only lost maybe 1hp with a basic 90. I feel that by sealing up my airbox I have: 1) Created the same restriction a stock airbox would have. 2) Created a very convoluted set of intake 'pipes' by forcing all the air through the ducts. So I am pretty confident I'll be going full circle and have a huge hot air intake pod and actually see a benefit. The air does *not* stay hot once it gets flowing, aided by the ducts, and the pod can then pull air from anywhere. All the posts of yore talk about the stock airbox costing 10-15kw at 300kw+ but you know what? I f**king would very much like that 10-15kw and I remember my own pod filter in engine bay experiences. Turns out the GTT Reo and Headlight brackets really don't allow you to mount GTR items, no matter what the internet says. Various brackets have had to be made up to actually make it fit right for the front bar. Also some idiot mounted a 3L Accusump right where the bumper wants to go, so that has had to be 'relocated' To where, I am still not sure, but it's supposedly mounted in the pictures and I can't see it.
