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?

-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

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.

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 :)

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

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

keen to see the results.

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.

    • Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance
    • Welcome to SAU, what are you looking at buying?
    • I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
    • I wanted to try and preserve the front bumper as long as possible, they're not cheap and are made to order in Japan. Taking inspiration from my previous K11 Micra build where I made an undertray for the Impul bumper, I did the same for this BN Sports bumper but a little slimmed down.  This time round I only made a 'skid plate' (if that's the correct wording/term) for just the bumper surface area, the Micra version covered the gap like an undertray. Starting off with a sheet of mild steel approx. 0.9mm thick 4ft x 2ft in size. I traced around the bumper, cut it out and cleaned the edges. Luckily I was able to get two halves from one piece of metal In the video I installed it as is, but I've since then I've removed it to spray and add a rubber edging trim. The rubber trim is suitable for 1-2mm and it's a really nice tight fit. The bolts had to be loosened due to the plates being too tight against the bumper, the trim wouldn't push on I used some stainless M6 flat headed bolts for a flusher finish (rather than hex heads poking down), I believe this style fastener is used for furniture too incase you struggle to source some. The corner's are a little wider, but this may be an advantage incase I get close to bumping it  The front grill got some attention, finally getting round to repairing it. Upon removal one fixing pulled itself out of the plastic frame, one side is M8 that fixes inside of the frame, where as the other side is M5. Not knowing I could get replacements, I cut down an M8 bolt, threaded it inside the frame along with a decent amount of JB Weld.  The mesh was replaced to match the bumper. One hole on the bonnet/hood had to be drilled out to 8mm to accommodate the new stud, once the glue had set it could be refitted. I think the reason the grill was double meshed was to hide the horn/bonnet latch (which makes sense) but I much prefer it matching the bumper Bumper refitted and it's looking much better IMO The Youtube video can be seen here: https://www.youtube.com/watch?v=bVZP35io9MA
    • The video for the servicing and fuel filter change can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44 One of the main jobs I wanted to do before the car officially went on the road, was to remove the awful looking blue silicone hoses. There's nothing wrong with having coloured silicone hoses, but I realise as I'm getting older I prefer monotone engine bays with a splash of colour on the engine cover(s). I cover this in a lot more detail in the Youtube video, so unfortunately there's limited photos of the process. The intercooler, upper radiator, boost vacuum and upper breather hoses were all changed to black silicone with mikalor clamps. The only blue left is a blanking cap at the back of the inlet manifold and the GReddy pulleys (which will be replaced for stock when the cambelt gets replaced) While the intercooler pipes were off I gave them a quick clean/polish too A before photo I do have a replacement air filter on its way. Fuse box covers were painted blue, they're now satin black Another job on the list while the bumper was off, is to add some mesh https://live.staticflickr.com/65535/54737966256_99b28bfa30_c.jpg[/img] I was hoping to use some thin wire to secure it, but it seems I've misplaced it and the wire I had was too thick to twist easily. I ended up using cable ties for the time being https://live.staticflickr.com/65535/54737131882_c2b7989dcc_c.jpg[/img] Was pleasant to see this https://live.staticflickr.com/65535/54737131627_8b2aab13b3_c.jpg[/img] The last thing to do was to fix the front grill and re-mesh that to match but I ran out of time The Youtube video can be seen here: https://www.youtube.com/watch?v=R4FsF6tgizE&t=23s
