Just need to know what the phyiscal/visual difference's are between the gt2860 -5, -7, -9, -10 etc.....

Some of you missed the etc lol

obviously on the GTR specific 5,7,9,10s they look identical yet gt2860 can mean other turbos too, IE gt2860rs which is completely different to look at.

Just make sure you buy the right one to suit your application, we are only assuming you want this for a GTR as you have not stated in your OP.

Thanks,

Yeah just seeing if they had any visual difference's. All your help has been great!

the part number is on the ID tag that it riveted to the CHRA.

Also if you measure the compressor inducer that will tell you what model you have; With the exception of -9 and -5 which have the same inducer but different exducers.

-7: 44.5mm

-9: 47.2mm (59.4mm Exducer)

-5: 47.2mm (60.0mm Exducer)

-10: 51.2mm

Actually you need to check the compressor housing size and A/R ratio . I think the GTR style GT2860R turbos can have either a T3 or T04B sized compressor housing depending on which compressor wheel it has .

I'm not 100% sure without looking but I think the ones that are 0.60 A/R are T04B sized internally where the 0.4x A/R ones are T3 sized internally .

If you could get the comp housings off the diameter of its backing plate at the diffuser section (the step outwards from the comp wheels exducer tips) would give it away .

Also I seem to remember OE GTR turbos having a turbine housing A/R size smaller than some of the RB26 style GT2860R turbos , I think OE and some of the more responsive 2860R's had 0.48 A/R T housings and the higher performance ones 0.64 A/R T housings .

Most would know that GTR turbos use a more compact turbine housing outline that single turbo versions and the comp covers have the two bolt in and out flanges plus the two eyes at the bottom to mount the fluid junction gadgets .

Cheers A .

    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
