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.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
