Did anyone else put these onto an RB30 yet?

Had it running the first time now, let´s see what they can do with stock head and forged bottom end...

The GTX2860R would be the one. U'd need to make sure you get the .64 "compact 5 bolt" turbine housings to suit the GTR twin setup. The biggest problem is making good intake pipes in the tight space but if a decent amount of time is spent, it'll be well worth it.

I'm starting to seriously look at a set of GTX2860's for my project as I was going to go the -5's.

I know it won't be a straight bolt in affair but I have a few ideas on how to make it look stock, using factory airbox, rubber joiners etc which will mean a 60mm inlet (i will keep 60mm AFM's).

Cutting and aluminum welding will need to be done as there is no way I am going to use silicone joiners on the compressor housings. Especially the back one.

I hope to find out if the stock manifolds will also clear the compressor housings.

My car is sitting here with nothing on the hotside,waiting for me to make mind up,its come down to the -5 bolton as i liked the boost response and no compressor surge, or these new gtx2860 turbos,worried about boost response and compressor surge as mine is only std stroke rb26 with glide,can anyone help with this any ideas or thoughts on how they would be..thanks

it wouldn't be that hard to use the existing twin turbo pipe either.

Cut off existing 2 bolt flanges until its around 2", weld on new extension/elbow and use silicone joiners to attach.

Vband welded onto compressor inlet instead of using silicone joiners?

This is what I was thinking.

The inlets, I would get aluminum pipe mandrel bent at the same angle as stockers and accept that it would use a 60-65mm inlet bellmouthed out and welded to the 3 inch shortened compressor snout.

I agree jangles. The v band idea would work well too.

ATP turbo how has a housing that is bolt on to the skyline... Im sure there were be some sort of difference in the 2 housings, If you want the full benefits of the gtx i would stay with the 3" intake with the anti surge, but im gonna try it out and see what happens. I got the 2860gtx. I was gonna get the -5 but I have been talking to ATP and they finally got it done. Like I say I will probably by the gunnie pig but oh well. I can change out the housing if it surges alot or something. But then again im probably not gonna be running big numbers yet and the limit of the 2860-5 seems to be more of the exhaust side than the compressor anyway, so this might be a compromise between the two, or it mike work just fine, we shall see.

Will be interesting to see back to back to back results with their 2bolt housing.

It might be worth welding alloy piping straight to the compressor inlet. To bad you guys are up in Sydney, I would love to have a crack at jigging them up. I imagine the GTX will be a common upgrade once all the parts are available.

As for surge, my GTX3076 is surging a little at light throttle, I assume the surge slots will help avoid compressor damage?

If it's anything like their other "bolt-on" type housing offerings for the RB range... You might be in a spot of bothing going down that route as they never seem to perform :(

I'm not in Sydney, but it doesn't make it any easier haha.

Well ATP called and said the 2860 with the skyline style is delayed. you can get the 2863 and 2867 though. Which works out great cause i just ordered a rips forged RB30 block. Now i have to decide on turbos. I dont want 800whp in a 2600 pound car so im trying to figure out what to order. what do you guys think.

    • Hell, I'm sufficiently wary of the ZSS suspension arms, let alone something like a hub.
    • Got it back home and got started pulling the hub off and diagnose the issue. Axle was stuck after removing the 36mm nut so i used a 3 jaw puller to try and push it out and... eH5FXvJ8.mp4   spend the next few hours trying to remove the axle from the remaining hub as it was very much jammed in there when the spindle sheared off. resulting damage as below R53AIy6 - Imgur.mp4   Looks like the was already a stress fracturing in the spindle as can be seen with the darker cracked section My working theory is maybe when the pinion gear exploded last year the shock put through the hub was the initial crack. Then a few events later it finally let go. Just lucky it happened where it did and not 190km/h on the next sweeper or into the hairpin The bearing/hub assembly went in in 2019 and were non-genuine "ZSS" assemblies and no nails were harmed in the process. #BreakHubsNotNails
    • Thanks mate, couldn't find in VIC, ended up ordering one from NSW, getting rwc to get new plates and registration done.
    • Before all the EFR fan boys come in, have a look at: https://www.garrettmotion.com/racing-and-performance/performance-catalog/turbo/g-series-ii-g30-825-58mm/ It also comes in a T4 1.06 divided housing. I would dare say if you want response & also decent power, this thing would chop.   AND apologies, just re-read your post, you've already bought the turbo... whatever you do, make sure you stick with divided housing and proper twin scroll manifold.
    • People have got to stop doing that. ShatGPT is not a search engine. It is a hallucination factory.   I also would recommend the 1.05. The .83 will "work" for you , in that it will be more responsive, but I think you'll find that it won't be anywhere near as good running it out to 8000rpm as the big housing will be.
