Thats possible, when I got it, it was supposed to be a gt28/gt28rs or something turbine housing. It doesn't fit on my gt28rs though. So we figured it was actually a gt25 turbine housing. Come test fit it, seriously.

I will when the turbo comes! Thank you. Is there a model/serial number we could get off of the housing?

Well if it fits, maybe I can order something from that number. At least we have a start.

Tim can you reference the turbine housing you have access to?

The turbine housing option I have access to is the standard "option" for the larger T2 series turbine wheels of 53.8mm (as opposed to 53.0mm). The garrett P/N is 430609-230 for the 0.64 A/R housing, 430609-231 for the 0.86 housing. I called my garrett supplier and asked if the gt2554 or gt2560 turbine housing (same item) was available seperate and they said no. Booo.

I don't have a 2554 or 2560 available off a car currently so I can't verify the casting number. Maybe Paul can take a look? the one on my subaru is well hidden :(

The belive 430609-230 .64 housing would techinally bolt on (I believe they are the same casting as the 2560's 0.64 housing) but the outlet hole around the turbine wheel is machined noticeably larger...much more than 0.8mm. So you'd probably get very little or slow boost, like clipping your turbine wheel.

No you are correct; GT28R is the old name for the GT2560R. That was confusing so ignore it; the new naming structure is much easier to understand. the first 2 digits refer to the frame size of the turbine wheel inducer. All GT25 units use a turbine wheel with 53.0mm inducer dia, all GT28 units use a 53.85mm dia.

My housing is the .64 AR one. So that won't match up with the stampings for that turbine casting.

2554 has a 0.64 A/R exhaust housing and a 0.80A/R intake housing. Yours is not a 2554 buddy.

hmmm. identify it then.

what exactly are these A/R numbers then because my 2560 has a smaller A/R than the specs you just listed for the 54, my 60 says A/R of 60 as you can see in the above pic

urbansoot, are you reading this?

Right. A/R isn't the only spec.

2554 & 2560 have the same turbine. 53.0mm wheel diameter (inducer, largest diameter), 62 trim, .64 A/R

2554 compressor: 42.0mm inducer, 54.3mm exducer, 60trim, 0.80 A/R
2560 compressor: 46.5mm inducer, 60.0mm exducer, 60trim, 0.60 A/R

I can't identify your turbo. It's not in my '07 or '08 garrett catalog.

I have a shitty T25, but the flapper assembly is taken out of the turbine housing. Not sure how you would use it but it's for sale.. cheap.
