Name these turbos

Turbo 1 shows a compressor of .48 and impeller of .64. I can't find a match on Garrett's web site.
The second is compressor .80 and impeller .64. I think it is a 2554.. can you confirm? Attachment 188812 Attachment 188813 Attachment 188814 Attachment 188815 Attachment 188816 |
whats the part number on the tag of the center section say?
|
no tag that I can see... would that make these knock offs?
|
no, #2 looks like a t28, has the nissan 3 bolt outlet with the larger inlet,
|
Morning bump for any more ideas...???!!!

Turbo 2 is a T25 from an SR20.
Turbo 1 has a bad compressor wheel. your pictures suck. |

are you going to be running one of these?
remove the compressor housings and measure the ind/exd. diameters snap a shot compareing the turbine wheels. |
Yea, I'll be running number two for now. I purchased the first blind and got robbed because it is useless without a new compressor. I purchased the second as a known good unit just to get the system running.
I'll take some pics this afternoon. |

ok pics and measurments. On the left is turbo 1 right is turbo 2.
I don't have a decent micrometer any more so all numbers are kinda guess work. Turbo 1 seems to have an inducer of 42mm and exducer of 52mm Turbo 2 seems to have an inducer of 42mm and exducer of 54mm Two people have identified turbo 2 as a T25 from an SR20. That seems really close to a GT2554, only 1/2mm different on the exducer. Is that the main difference? What would the measurments make the first one? Something around a 2252? The A/R does match, but the size is close. Now the pics... Attachment 188782 Attachment 188783 Attachment 188784 Attachment 188785 edited for different pics |

Is that the main difference? Im going to guess they are both the same sized turbo. Not many 52mm wheels floating around, although the blades look different. 5 blades vs 6. shame they are slightly different can then you could use the better housing on turbo 2. the sr20 turbo is sized like a 2554. main difference is journal bearing vs ball bearing. it's a great little turbo to use for a ~220rwhp install. |
