specs of the ARMS B7660 look similar to the 2860-5's however have a smaller comp housing...

ARMS B7655 look similar to -7's but again smaller comp housing from memory.. cant be bothered looking into more details at moment.. will do tomorrow if someone doesnt answer it properly before than

Interesting , it looks to me like they ARE Garrett turbos - or cartridges anyway .

How they look to me .

1) 60mm 55T compressor , probably same cartridge as GT2530 but with 55 rather than 63 trim compressor wheel .

2) 60mm 60T compressor , as above but 60T - possibly same cartridges as used in SR20 spec HKS "GT-SS" .

3) 76.2mm 46T - Hmm sounds like the T04E wheel from the HKS GT2540 . Turbine spec looks like the cropped (56.5mm) GT30 turbine found in some HKS spec GT2835 cartridges .

Not based on experience but I think the best most responsive cost effective turbo upgrade for RB26's is the -9 version of the Garrett GT25/28BB range . This IS a HKS GTSS without the HKS actuator .

For a bit more without too much turbine lag 2530's or equiv .

You get into a grey area after that because you either opt for more compressor ie GT2871's (IE GTRS) or larger turbines (IE GT2835's) .
