anyone has any idea?

Any more pictures? You show a compressor not a turbine.

there is normally a tag on the garret (like a vin tag) that tells you what it is on the center body of the turbo

Scuderia - I've added some pics of the turbine.

Bernie - the tag is not attached to the turbine or the compressor anymore.

Thanks all

Really you need to remove the compressor cover and measure the inducer and Exducer of the wheel - and also take some full pictures of the compressor wheel

It is very hard to tell from the picture just looking it.

If you decide to just be careful that everything comes apart square (the six bolts around the compressor housing) and you mark where to put it back.

From this you will be able to calculate trim

Trim = (minor diameter / major diameter) ^2 * 100

and the size should help to tell which wheel it is.

Below - taken from the SRT forums so can't vouch for it 100% but gives an idea - inducer sizes

Some quick facts
GT28 ~ 2.10”
GT28 ~ 2.20”
GT30 ~ 2.36”
GT35 ~ 2.68”
GT40 ~ 3.03”
GT42 ~ 3.23”

Just for the record, Turbonetics likes to confuse the matters a bit. they alter their numbering a hair.

T3 ~ 2.32"
T4 ~ 2.92"

Thanks Saint, Will check it out if i really decided to open up my turbine.

It sure looks alot like my turbine housing.. I seem to have an integrale group a housing. (turbine is stage 3 tho)
