Yeah it seems like the only legit twin setup is the G25-660s. Unless some tries a custom precision setup 5558 or 6062. 

Sad that twins are pretty much dead for now. Just something about seeing snails full of blades ready to scream under the bonnet.

Oh well. Maybe I'll go a billet RB36 with twin 6466s. 🤘

I actually ran the australian agent about a xona 9569 not long a go as a upgrade to a 6870 on a rb25/30 neo

He said keep the precision and just add a bit of gas as the xona be lucky to make more on a rb30

He said the precisions they sell are more reliable than the xonas.. Stated they where very hit and miss in reliability...he basically sold himself put of a $4500 deal as i would of pulled the trigger if he said otherwise

Interesting, yeah I personally wouldn't swap from a 6870 to a Xona (or vice versa for that matter) - they are both similar enough that it's not going to be worth the money.

The reliability thing sounds odd, haven't heard much issue about them at all.  Is it definitely the Oz agent, or someone who can get Xona rotors but sell precision? Lol

I'd love to hear about any of them having failures if they're that common, as obviously they've caught my attention and so far looking at individuals experiences I've only seen Precision reliability issues (granted, that's probably partly tied to people just sending it with them) and people getting performance improvements going from Precision to Xona.  I've not seen anyone have any Xona failures anywhere yet, though they also are not used as much so it's hard to get a failure rate but I definitely don't want to be suggesting something that has any problems.

Like anything, any claims without proof or data should be taken with a huge grain of salt.

 

 

I can't recommend on size as at those power levels I have no experience with, but the only thing I can say is keep it divided/twin scroll..

You'll need all the help you can get to spool the karnt.

Fair call. Was thinking of staying with the smaller 1.12 T4 devided.  Sounds like the way to go.

Garrett just launched a new disco potato! 🤯 Still prefer the simplicity of a single, but found it interesting enough to share with you.

GBC22-350

Man that would be killer setup for a 2.6. You'd hit full boost by 3500. Gearbox braker. I wonder if this is a new generation of turbos again.

I am also quite interested in these new Turbos. My goal is staying with the twins in order to avoid unnecessary attention and it seems like these would be powerwise close to the 2860-5 and spoolwise closer to the 2860-7. Unfortunetaly i think it will take some time untill  we see real world results.

Gen 2 7685.

Beast, in a manual you'll have no problem achieving 1100hp. My old 7175 went 1021rhhp 35psi through the auto. Currently have a gen1 7685 will be going onto the hub hopefully this month.

I hope so. I think it will come down to the skill of the tuner.

What's the rest of your setup?

Keep us posted with your results if you don't mind.

Yeah will do mate. Its a 26/30 3.4 stroker with a powerglide behind it.

How do you find the 3.4? I was talked out of it at the time of my build and went 3.2 instead. Now I'm considering selling up and going billet 3.6

Its a torque monster, very hard to get it to hook up especially being rwd. In a gtr would be awesome. It probably needs a dry sump but so far its been happy with the wet sump. 

The 3.6 is a 3.4 with a few mm oversized bore right? 

It's both bore and stroke. Can only be done with billet block due to amount of meat that needs to be removed to accommodate the crank and pistons. I've yet to see one reviewed in any way but they use much wider bearings to make sure the extra side load won't chew them out. Sounds amazing.

    • 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.
