When does it hope to have boost, 4th gear? Lol

Well they get big pro mods on boost, the car is being set up for drag racing, not street duties

Yeah with methanol and big auto stalls to get 1000psi of boost and all that - this is crazy 2000whp+ stuff - I like👍

Yep, two of my turbos! Lol

Out of curiosity, what is the 6875 like ?

Just took my 32 for a drive and still think the 6466 is fckn mental, but have always wondered what a 6870 upwards turbo would be like realistically outside of drag use.

I had a feeling it would be a drag car with a big converter and a lot of gas to get it into the converter

As stated in title, when you’re hell bent on twins, but love singles, this is going in my mates car. Should make some serious numbers.

Haha that's actually pretty damn cool, I have to admit I was always a huge fan of the old Japanese drag cars running 3240s etc - they had an epic sound to them and looked choice under the bonnet and I'm sure this will look and sound unique, albeit I don't think twins are actually functionally that great a prospect on RBs and while I hope it works... especially with this turbo combo there's a good chance it may prove to be quite a headache trying to make it work as well as the 102+mm singles you're effectively trying to compete with here.

VERY keen to see how it goes, though!  Any more details on the engine spec?

CRD built 3.2, wide journal drag spec bottom end with CRD race port head combo, not sure of the exact specifics, will be running auto and NOS. 
I like that it’s something different, sure he could have run a pro mod like all the others (in that league) but you don’t learn if you don’t try. 
Car looks mint and is coming together really well.

I don’t know, car is still in pieces, will update my build thread soon as I will be pushing forward and try to get it back on its wheels in the next couple of months. 
the 68/70 on the 3L was awesome, but I honestly couldn’t really feel the difference between it and a 2.6 with a 64/66 (a mates car). But at roll racing I had an edge on him in acceleration. And that was when I was lifting the head and running 28psi vs the 64/66 running 32psi. 
The new 68/75 I bought will be going on my new 2.7 motor so will no doubt be vastly different. I’ll let you know when it’s finally together.

Kind of related to the topic. There is a twin trust T67 kit up for sale for 6k includes turbos, manifold, waste gate, down pipes, oil/water lines, twin entry trust drag intercooler and pipes from turbos to intercooler. They have been rebuilt and are in good nick. I am really keen to get rid of my 7685 kit and get that. I remember hearing and seeing that kit on Kier Wilson’s R32 when he ran 8s. These things look amazing and sound insane. They would spool ok to on a 3.2 with a sequential on e85. Looking specs, they flow up to 750hp each.

What are you hoping to achieve by going to a setup from 1912?

what’s wrong with your setup at the moment? What are you trying to achieve by changing everything?

Seems like a pretty backwards move with turbos with overgrown heavy wheels, journal nugget bearings and just general shitness.

Remember this car has never been run with the combo mentioned.

This is funny - Looking at moving to a Trust twin high mount setup from a 7685 that has never been installed 😄

At least try the Precision first. Not happy ? Maybe move down to the Gen2 7275 / 7675 or something than this Trust twin idea.

Don’t get me wrong a big set of twins look cool but turbos have come so far since they were made and it would be a huge backwards step

Always wanted to stay twin. It was the early 2000s GTRs that got me hooked. Kiers r32, GTR700, HKS R33, all the big twin monsters.  Call it a tribute if you will. Plus these twins have been rebuilt with billet wheels and new cartridges. So I’m not really moving back that far. Every high powered gtr is exactly the same these days. Yes, because it works. But there is nothing wrong with being a little unique. It would be much cheaper and less painful to do it now while everything is still in pieces and my parts are brand new.

    • VP race fuel like VP 109 ron unleaded is a waste of money compared to E85. Just go flex fuel setup so you can run on pump unleaded or E85 all without draining tanks or switching tunes. You go VP race fuel you will have to change tune when using it, then change back to a pump unleaded tune. VP109 for example will support about the same boost and timing increaes as E85, but it requires the afr's to be a lot leaner than E85 but richer than pump unleaded.
    • Whats your budget? Maybe call Nispro in QLD for quote - they build a lot of VQ and have a turbo kit in development - but id say at least 20k to do it right - oh actually maybe do LS swap will be cheaper but....hmm  im a purist - so id rather stick to VQ35DE or whats the point lol.... just my opinion - do what u want. its your car  
    • Ok sorry I should rephase my question. But good answer haha.  How can I make 400whp that isn't using nitrous. 
    • dyno run would be on VP race fuel or e85 / e98, E85 is not easily accessible by me. Closest pump is 30 min in a direction I do not travel. So while I will go out to get it. It will also get pump gas 93 octane is highest avilable in US so overall power will be down if mix fuels  e50, e30, e10 ect 
    • Cheapest way? Spray. A wet kit with 200hp jets could be up and running for less then $2000. Then its about $16 per pound when its time to refill your bottle.
