New Garrett Gtx2860R / 2863R / 2867R

Not sure where you got it doesn't include an exhaust housing?
Because it talks about the exhaust housing it comes with on there...

You're right, I skimmed through it and saw the image.

Has anyone seen or heard of someone shoehorning a GTX 2860 into a -9 or -7 housing?  I have heard that it is possible but just haven't seen it done yet.  I think from memory you still need to use a -5 rear housing?

[sneakey pete]

-5 rear is identical so it's best to use that.

Front wise -5 is to big and you'd need to use -9 from memory. Back a few pages are the gtx 2860s that I did but I used some weird stock turbo covers

Have you seen any power / dyno results from them?  I remember that you had them built but sold them on, trying to weigh up whether the extra hp over -9's is worth the $$$$

I posted this car earlier. It has since gone to a crank trigger and a few other tweaks. New engine so this is how it is for the first few hundred kms before cranking it up again.

 

Did this at 30psi previously. Still same GTX2863's

[Skepticism]

that ramp is pretty crazy.

at what rpms gtx2863s  go to 0 and when to go 1kg? rb26 264 cams

How do they spool when compared to -5

I guess you could use the OEM comp hsg so sleeving is not required, In my humble opinion this would be a compromise so I just used some old HKS2530 hsgs which are T04B style (aka 5s) with an AR of 0.6

The OEM hsg. A/R is 0.42 and although from what I have read the A/R on the comp. side does not affect things too much unlike the hot side A/R which has a major affect on spool.

Using the OEM comp hsg might make it boost slighty earlier possibly hotter also. Just what I have read.

Anyway I prefer the HKS 2530/2510 gt2860r-5 housings of 0.6 A/R.

I just turned up 2 x 6061 aluminium alloy sleeves 60.00mm OD 42mm ID x 48mm long. Bored out housing to 59.94mm . heated the housing up with heat gun (measuring it to make sure its bigger than 60.00mm) , cooled the sleeves down in freezer then dropped sleeves in the housings. Once cooled machine the profile to suit . Interference fit is permanent like welding but no distortion. I put 2 scotch keys in as well although that was overkill but thats me. The important thing is the 0.06mm interference!. Best not to press it in cold either as it may gall.

Hope this helps some people out wanting to use GTX2860r CHRAs' with Skyline housings.

Keeping my fingers crossed they will be better than my 5s in every way.

thx for idea ) tuning my hks GT2510 to garrett GTX2860

 

Can anyone help me? is this map correct? 264cams 2.6

So I sold my -5's to a mate. Going on a z32 tt.

Gtx2860's are back on and setup with no boost leaks this time.

New engine and run in nicely. Still a 2.8 but nitto and crank trigger setup.

On bp 98 and 22psi goes pretty well. On e85 better again. Will get dyno tuned soon and hopefully run some more boost. She's spiking if I try to turn up gain. More work needed there.

Some custom intake pipes might get made up to replace the stock rubber ones. Running a mines front pipe with 89mm outlet, 100 cell cat and 89mm full exhaust. Not setup to dyno queen, but just haul in general

The general gist of this thread is people say good luck and then get ready to say 'I told you so' in a couple of weeks [emoji23]

[r32-25t]

You missed a few steps. it's normally people saying they don't work, the poster say I'm going to make it work, everyone saying ok good luck, the poster saying it didn't work, everyone else saying we told you so

[The Mafia]

not sure what drugs you guys are on, but GTX turbos will be much better than -5s. 

keen to see the results.

[r32-25t]

Might want to have a read of the last few pages and see all the people who have put gtx wheels into gtr housing and then see how many came back saying how great they are

Every result posted has shown otherwise? 

Putting GTX compressor wheels into compressor housings they weren't designed to be in, along with turbines that dont have the flow to generate the revs needed for the extra boost required for a GTX wheel to "do its thing" will be much better will it?

Be happy to be proven wrong but history will repeat itself.

Post 137. One of many examples.

J.U.N.K!

people seen these?

Okay I missed those posts. I thought they would have performed better.

 

Those ones above look interesting. I wonder if you can put smaller rear housings on them, like a 0.63

[Piggaz]

What about letting it out too?
