Does anyone know what nissan turbo is a "2560"
Does anyone know what nissan turbo is a "2560"? I find a ton of T25's T28's, T28R (2560R) but can't find out what nissan turbo number is a "2560" that is best for our cars.

I believe the infamous "T28" found on the sr20, is basically a 2560.

Garrett Part No. 466541-1
Nissan Part No. 14411-69F00 Garrett Part No. 466541-4 Nissan Part No. 14411-91F00 From Garrett's catalog for the GT2560R: - Dual ball bearing, oil & water-cooled CHRA - Internally wastegated turbine housing complete with actuator - Turbine housing is cast from high-nickel “Ni-Resist” material (466541-4 only) - Turbine wheel is cast from “Inconel” material for extreme applications (466541-4 only) - OEM turbocharger on Nissan SR20DET engine |
It's only on S15 SR20s. The run on the mill S13 and S14 motors aren't 2560s. Also, a 2560R is a 2560. The 'R' just denotes ball bearings.

So basically they're rare on nissans, and still not the real deal ball bearing 2560 everyone on here raves about
Still nice tho |
All s13's used a 56mm compressor wheel which makes the turbo similar to the gt2554. This is the most common sr20 turbo.
The s14 used a 60mm compressor wheel and it was basically a journal bearing 2560. |
The S14 turbo is very much a regular ass T28.

seems to be a lot of conflicting info.

Guys, this is simple.
S13 red/blacktop turbo: Small t25, journal bearing, a 2554 basically. s14 notchback turbo: bigger t25, journal bearing, a 2560 basically. s15 vvt turbo: bigger t25, BALL BEARING, same size as s14 turbo - 2560 basically. So you want a BB 2560? Find a s15 turbo. I THINK (not sure though) some of the late s14 motors also had these, but still rare. Edit: just read thirdgens post above. Looks like the s14 "silvia" was ball bearing as well? I do know the ball bearing versions are the rarest, but i've seen them for around 350 bucks a few times now. This is what I'm getting for my new build.. ;) |
Late s14 turbos had a single ball bearing on exhaust and a journal bearing on the intake side. s15 turbos had dual ball bearings. Hope that clears some things up.
