Thread: Is this turbo any good for 4bd1

not sure off the numbers but mine is a garret T25 from turbo glide, some of the gurus will be on here later mate but should imagine it will be fine

thattle do the job for you and should be comfortable with about 15psi of boost. just got to plumb it up nice.

Thanks Blknight. By "plumb it up nice" you mean to make sure I'm not losing anything in crap plumbing?
The plan is to run a front mount intercooler, so the plumbing should be pretty straightforward.

What's the A/R on the exhaust?
Does it have four or 6 bolts holding on the exhaust housing?

It is suitable, but the answers to the above will give a bit more information on what you can expect.

more or less.

the boost number I gave is fairly generic and as mentioned by Dougal its actual performance max boost where and how it delivers will be determined by other factors.

Its got 4 bolts on the exhaust housing (the round ring between the oil feed and the housing) and 5 bolts on the dump side of the housing.

Just found some more numbers on the exhaust that I didn't see yesterday:
Cast inside the manifold flange : 64
Cast on the outside of the exhaust housing near the manifold flange:
AR64
M3 (could be M8)
028

Also found a typo in my original post which I'll fix.
the number should have been TD 0266J (I'd put TD02665).
Must get these lights in my office replaced

Bugger - found another typo in my original post (which I cant edit).
For completeness here are all the numbers corrected

Compressor housing:
M24 AR .80

ID Tag:
TD0266J
14411-79E00
466075-1

Cast inside the manifold flange : 64

I just found a reference to it being a T25G which was fitted to a Nissan Bluebird.

Does sound like a T25G.

4 bolts means a journal bearing core, 6 bolts means a ball bearing core.
0.8 compressor and 0.64 turbine A/R's also matches the T25G which is a T25 with a larger compressor wheel.

There is some confusion as to whether these turbos have a 54mm OD compressor wheel or a larger trim 52mm compressor wheel (actually measures 51.3mm OD).
I have had a large trim 51.3mm compressor wheel and housing in my possession before, but not a complete T25G. Any chance you can pull the compressor housing off and measure?
