What Nissan Turbo is This?

[rico05]

Sneaking suspicion that I have a Z32 TT T25 on my hands. T25 compressor A/R .80 Any thoughts?

[Nismo_Freak]

SR T25 ... Z is small a/r. (.48 or so)

[rico05]

After a quick Goolge search (and the reason that I made this post in fact) I found that all of the website (UK, US, and Aussie) list the compressor A/R of the SR T25G as .60???

Could it be a turbo from an Rb25DET? I've been told that turbos with an A/R in the 80s are designed mainly for 6 cylinder applications, but twin turbo setups typically use 2 smaller turbos, so that left the RB25 in my mind.

RB25 has a T3.

ITS AN S13 SR20DET TURBO...

I AM 100% CERTAIN...

T28's have .60 a/r compressor side but have a larger wheel T25's have .80 a/r compressor side for S13 SRT25's have .40 - .50 a/r compressor side for the S13 CA and Z32 and RB26

OK ALAN. NO OFFENSE BUT YOU ARE HUMAN SO I TRIED OT TAKE THAT INTO ACCOUNT SINCE LITERALLY 10 WEBSITES/FORUMS THAT I CHECKED SAID THAT THE SR T25 HAS AN A/R OF .60.

You can find 10 websites that say all S14 motors have ball bearing turbos, this is not the case. Same with the S15 turbos having ball bearings and inconel wheels, two commonly incorrect "facts".

For later reference.

The Skyline RB26 turbo has a smaller inlet on the exhaust side, easily identifiable.

The Z32 turbo has very small A/Rs and is about the size of the CA turbo... it's essentially a T22

The Z31 T25 has a T3 flange on the exhaust side to my knowledge, might double check on that

The RB20 and 25 have T3 flanged T28s

And you know the spec on the CA turbo

T28's also have different clocking of the inlet bolts as you're aware of

It's nice to know that you know everything Alan. Heh

i am under the impression that early z31 turbos had t3 60trims and the later ones had t25s of some sort.the z32 turbo is called a tb022 by garret and has a t22 compressor wheel. so i imagine it would look really small. i dunno though.

edit:you can see it bigger at my cardomain site(in sig)
