TD04 Manifold options?
 

So I wrangled myself a free turbo (TD04L-13T) and TMIC off a Forester XT.
I was originally set on buying a BEGI kit and making things easy, but my lizard brain wants me to horde turbo parts in my garage for years in order to save $200.

I did some searching and my options for TD04 manifolds on a 1.8L seem to be:

ETD (used)
HKS
ARTech custom
Treadstone DIY

My goal is for this to be a low boost, really cheap, really responsive street setup. ETD appears to be out of business, and the HKS site is an engrish clusterfuck. Am I missing any other manifold options?

I just have to say that getting a free turbo that doesn't have a T2 / T3 flange, and then trying to build your turbo system around it is a big mistake. I'd highly suggest getting a turbo that uses a flange that can be used with commonly available turbo manifolds.

HKS turbo parts are also very hard to come by. Ever since they left North America it's near impossible.

I can agree with this especially If you want to upgrade soon, Which I can say as a guy who also has a 13t turbo on a miata.
The subaru upgrade turbos are either really big journal bearing turbos or super expensive (and still too big) ball bearing turbos.

I did find one. Midwest turbo will rebuild a td04 with the HL turbine wheel and the 19t, that turbo "should" be able to hit 300 but I've never heard of anyone running them subie or otherwise. Its a bit spendy for "just a td04" but cheaper than any other non-stock and non-crap upgraded subie turbo.

subaru diy setups are only worth it if you can weld/fabricate yourself.
if you cant, its a pain and you still end up with a mediocre-at-best setup.
with the prices of t25's the way they are, you're not saving any money going td04. just limiting yourself on off the shelf parts availability

Don't build a setup around a turbo. If you want to use that, stick around a bit and see if someone sells a used TD-04 setup. Otherwise sell the turbo and get a used T2 setup, which are much more plentiful. It will probably be cheaper than your free turbo (which will not be cheap unless you can weld).
