I assume this is a gtst or gtt, if so just buy a turbo and fit it don't bother trying to make hybrids as they don't work 

Rb26dett gtt r34. Sorry for my bad eng. My rebuilted turbos 2510 worked well for 3 yeas, quick spool 3000 1kg, max boost 1.8. but unfortunately in them something was horrible and damaged the wheels. Then I decided rebuild they and to increase the rear end of the turbine to 2530. But 2530 is a very old turbine and I decided to look at the catalog garrett to  search of a new turbine and came across a GTX2863. I want to take the chra (cartridge) of GTX2863 and put it in the hks body while increasing the rear of the turbine and compressor housing. but on the calculator comes out a very lagly so it is. or it is better to stop at 2530. There where do the turbines said that after boring the rear and the front hull hks differ from GTX and will not be. They said that it would give an exact copy of the turbine GTX2863. In Russia, this is the only company that manufactures qualitatively turbines on a double-saw saddle-bearing.

Then spool up original twin gtx2863 on rb26?

*cough* current M3 and M4 are twin turbo...

But... a bigger motor and proper variable cams.

Things a GTR should have had in the 34 :(

Hrms.. you may be right for that lol

Every "experiment" with larger GTX wheels ends up with anti climatic results.

If you want to burn money correctly I suggest you go a big twin scroll turbo and be happy. Every owner who wants response, driveability and big power all end up moving to a modern single. If it took BMW only 3 years to work out twins are gay it's sure taking a damn while for you GT-R boys.

I will take the risk

rebuld my hks GT2510 to GTX2860R

Voodoo did his and they were a disaster and sold them for a lot less then it cost him in the first place 

his change only compressor wheel to 2863, i  change all enternals (CHRA) 

he did not increase the back, it turned out that there is a bottleneck

he changed only the compressor wheel, and I changed all the insides and grind the turbine house (replace to GTXCHRA 2860)

2860 wheel less than 2863

 

 HKS GT2510

COMPRESSOR:
-Wheel- 63 Trim - 47.7 Inducer / 60.1 Major -Housing- 60 Inlet / 50 Outlet - 0.60 A/R
TURBINE:
-Wheel- 62 Trim - 53.0 Major / 41.7 Exducer -Housing- GT25 inlet / Internal GT25 oulet - 0.64 A/R


GTX2860R

Compressor Wheel: 45.7 / 60 mm / Trim 58 (GTX 11+0 Blade billet Wheel / Extend tapered tip)
Turbine Wheel: 47.0 mm / 53.8 mm / Trim 76

That's cute mate.

How do you plan on making the smaller inducer of the GTX wheel fill the larger hole left by the GT wheel?

Do yourself a favour and forget about shoehorning this and that into places where they don't belong. If you REALLY want to run GTX 2860's then do it properly and run the genuine GTX housings and redo the pipework to suit (IE 3.0 inch all the way to the compressor covers) and do away with the small, tight Nissan gear.

    • What an awesome idea to fit the facelift Lamborghini Diablo headlights. They are a perfect fit!
    • An update regarding the registration with the DVLA I sent off the paperwork the day after I collected the car from the port, two weeks later it was all returned with a letter explaining they have rejected the application. This was because the cheque was £20 short for the road tax (I used a price list I found online). Nevermind it is what it is, it was sent back to them the following day with a new cheque. Fast forward another 2 weeks or so, I called them for an update to be told it had been rejected. Yesterday (16th September) I received the documents back along with another letter, this time it was because I didn't put an X in one box on the V750 (personalised number plate certificate), which declared that I had the rights to the personalised number plate. Why this wasn't mentioned in the first rejection letter, I don't know, but it could have saved this headache. The documents were sent back today, so fingers crossed third times a charm and it'll FINALLY be registered on the road just in time for the bad weather (woohoo!) To cheer myself up I lowered the front 25mm, was sick of seeing it sit like a monster truck. No idea how much clearance I'll have getting on and off the driveway, I'll worry about that when I can actually drive it
    • You're going to miss not worrying about rust in the strut towers like the Skyline shitboxes out there
    • A few little updates that weren't filmed due to not taking long to do or not interesting enough for their own video. My new K&N Air Filter arrived, I went with an RU-4180 which matched the dimensions of the universal cone filter the car originally had.  The battery had gone flat, while that was charging I tidied up the spaghetti wiring at the bulk head and down the sides of the engine Next job was to swap the stereo The Kenwood harness had the female ISO plugs cut off and the male ISO plugs cut off the adaptor loom and joined with bullet connectors. I ordered in a repair loom through work and re-did it all. New Kenwood unit installed (Android Auto, DAB, Bluetooth, Reverse Camera) The bonnet/hood gas struts have been poor since collecting the car. I couldn't find any suitable replacements locally so took a chance on a pair from AliExpress.  The originals don't use a retaining clip to secure the cup onto the ball fixture, would explain why I struggled for 10-15mins trying to pry off the cups. The ball fixtures unscrew using a 12mm spanner, new ones are the same size. Sadly no photo of them fitted, you're not missing much lol The dished Momo steering wheel got replaced with my Momo Tuner, turns out I ordered counter sunk bolts for the horn trim ring (like they normally are for the steering wheel) instead of allen cap (flat seat)  A terrible photo of a Quaife style gear shift knob I've had stashed in my tool box for many years after purchasing the incorrect thread size (I can see a pattern emerging with ordering incorrect parts...) Also threw in a cup holder and a (empty) Boss Coffee can, because why not  
    • GT-R clearly the better choice! The 300 is certainly not insaly fast but has a decent amount of poke. Does a nice little drift around the corners with a decent amount of throttle. It's VERY predictable in a slide too.  Feels so progressive! People probably presume there's a 25 year old driving it based on my behaviour this week! 🤣
