Garrett M24 T25/28??

[turbominicooper]

Hi all,

I got this turbo off my mates Civic D-series conversion and am trying to figure out wether its a t25 or a t28.

The reading on the comperssor side is:
Garrett M24 A/R80 1-1

The reading on the serial tag is:
471171-5003S
LF10395Z

The reading on the exhaust housing is:
449010-1
64
M3
79H MK

Anyone got any info on this? How will it sit on my 4EFTE?



Cheers

dont worry just googled the serial number and found:

471171-5003S Garrett GT2554R Ball bearing turbocharger:
- Oil & Water-cooled bearing system
- Smallest ball-bearing turbocharger available
- Internally wastegated turbine housing
- T25 turbine inlet flange
- Great size for applications with packaging constraints
- Ideal for smaller displacement engines making up to 270 BHP.
- Fitted with 1.0 bar acurator

Big Smiles!

I want this turbo
Should be like a TD04+-
Just have the turbo checked by a turbo rebuild shop before you go through the trouble to fit it.
A ball bearing turbo can be blown and you won't know it.

Did these come standard on something I wonder

 

[Skalabala]

Yes they did. Very few Nissan SR20 engines and a few other cars. Mostly they come in twin turbo applications.
And I think you get twin GT2556R turbos on RB26

 

[turbominicooper]

ill let you know how it goes when ive got it on. going to be documenting every step and mod on youtube eventually so can see progress

 

[aidan]

That's very small to be on a Sr they had t28 turbos

 

[Tim@TBDevelopments]

the factory nissan stuff was T25 and t28's not GT

GT denotes a next generation dual ball bearing turbocharger. the nissans used to older T range turbochargers which were oil journal based

Some of them did come with Ball Bearing, Tim

rust is a big issue for you fellaz ain't it.. :/

 

[Tim@TBDevelopments]

Some of them did come with Ball Bearing, Tim

really which ones?

 

[aidan]

very late s14a's and s15's have ballbearing turbos but all 28 series not 25 series

 

[Tim@TBDevelopments]

you sure as the later s14's and s15 i've worked on did indeed have a T28 series turbocharger but it was journal bearing not Ball Bearing. Could tell by the oil feed line to it.

 

[Tim@TBDevelopments]

stand corrected. had a look and apparently the s15 came with both journal and BB turbocharger, depends on model, spec and year of the car

Yes, as I said you do not see it often

 

[dark_knight]

just goes to show that indeed experience is widespread. i like that Skalabala and Tim didn't get into a fuss over this and handled it like gentlemen..
other times, people get all shouty and vulgur when on thinks they are right and are corrected..

 

[Tim@TBDevelopments]

lol never bothered me to admit when i'm wrong. end of the day everyones still learning and i don't claim to be an expert on nissans lol.

 

[Skalabala]

Its because Tim is a grown up man in mind and body
Just wish he will send me a free head gasket

 

[Tim@TBDevelopments]

grown up in body a little to much is the problem haha.

I would be pulling that housing off the turbine outlet, it doesnt look very free flowing.
