I picked this turbo up in a kit I bought last night, and would like some help identifying it-

The compressor housing is Garrett, and has the markings
"A/R .60 M24"






Now Ill be honest, I dont know which parts to measure, so I took a few-

1) This is the inducer and it was roughly 58mm


2)The exducer was 74mm


3) The inlet for the turbo was roughly 75mm was well


4)The inducer on the exhaust turbine was about 57mm (I didnt take off the exhaust housing, so I cant measure the exducer)


So now, looking at the exhaust housing, it is just a 5 bolt housing, but then there is this:

That is a turbonetics logo correct?

So does anyone know what turbo this is? Is it botched together, or was it a popular combination or some sorts back in the day lol?

If its any use, I purchased this in a inlinepro turbo kit-

I guess what I have is t3/t4oe with 60 trim on the cold side, and uknown (for now) trim on the hot side?

Any input thanks guys!

Trim is measured distance b/w inducer and exducer. You found the trim basically on the compressor side. More than likely the way turbonetics used to make these, they were stage III exhaust wheels, so those make about 440whp at its maximum efficiency. It was probably a turbonetics that had its compressor housing changed. Remember, there was a time that Turbonetics was the only outlet that Garrett gave to the public before they marketed directly themselves.

Good information- you know too much!

So for the exhaust turbine trim, measure the exducer and the inducer, and then apply this:
Turbine Trim - The trim of the turbine refers to the squared ratio of the smaller diameter divided by the larger diameter multiplied by 100 of the compressor wheel. The smaller diameter of the wheel is known as the inducer, and the larger diameter of the wheel is known as the exducer.

Correct? If so, Ill try and do that tomorrow if I can get the housing off-
