not a very practical upgrade hp/$$ wise....the 16g's will make more power and are almost half the price....

I do think it's expensive for the power, but I also think it's interesting that they're coming out with turbos specifically directed at the WRX.

Why go 16G when you can get the same power out of a VF series?

the 10cm turbine housing is what interests me. it would be a worthy upgrade on a 2.0 WRX, not sure about a 2.5 WRX or STi though.

I DO agree that the bigger hotside would seem to be better paired for scoobs then these tiny turbine housings we've always had...

I think the 10cm hot side is oversized for that flow rate. Subarus have a lot of volume between the heads and the turbo and I believe this is why they tend to do ok with relatively smaller hot sides.

You want to see a 10cm hotside on a Dom 0.5R (GT28RS)? I really don't think there's enough compressor size to take any real advantage of the 10cm hotside, but you'd lose the spool... I think based on what I've seen an 18G would give a better overall curve.

However, there's not a whole lot of GT28RS data for WRX, as there's not many people willing to pay $1400 for a 16G / vf39 sized turbo.

What I really meant is that I'm excited about the 10cm housing, but not necessarily on this tiny turbo. The 2.5XT-R with the 10cm housing should be the real performer. Agreed that the little compressor on this turbo isn't well-matched to utilize the 10cm housing.

Concillian - the 0.5R comes with the 10cm housing. All of the "XT-R" turbos do.

There is no consistency in the R naming. the 2.5 and 3.0 R= 8cm and XT-R = 10cm, but the 0.5R is 10cm... no consistency.

0.5R with 10cm housing isn't going to be a good match IMO. It's too big for a turbo of that size, which can only be intended for the 2.0L engine, which responds much better to 8cm or even 7cm housings. By the time the ej205 is flowing enough to take real advantage of the 10cm housing, it's out of RPM.

And IMO the 2.5XT-R is a turbo without a market. 2.5R is for the people who want 20Gish power (yes, slightly more) with ball bearing response benefits. The 10 cm housing in the XT-R takes away spool & response and adds top end, the end result is a turbo that acts a tiny bit smaller than a Dom3.0R, but the same price. Most willing to trade off spool for top end and go bigger than a 2.5R will choose to buy the the Dom3 instead for the same money.

Just my opinions though. However, clearly the Dom 0.5R hasn't sold well, or there would be a dyno of it somewhere.

Yeah since the 2.5XT-R only flows 49 lb/min, its on par with the non-HTA Green which is nothing to write home about, but a nice upgrade for people not wanting to go 30R/35R territory. I guess the 3.0XT-R will be the next popular turbo. I just think the Subaru market has needed a larger turbine housing (stock location) for a long time. The Evo comes with a 10.5 housing stock, and I know they're different motors but maybe they can design it to have good top end via the 10cm housing yet still retain spool.

Is the .5r a bolt on turbo, its the only one on the subaru subsection that says no?

I was told about it and it sounded much more promising then it actually looks on paper. I would love to see some charts on it but for the money i would rather purchase an 18g or 20g.
