Its a great turbo to upgrade too. Awesome torque and almost no extra lag over stock if any.

I would prob good with the SZ49 if your goals are 400whp. You could make that on the 20g but you will prob need meth injection. Better off to just get the sz49. it has a 49lb/min wheel compared to the 20gs 44.5lb/min. 20gs usually make 330-360whp.

20G is not what you want for +400 Whp, its a great turbo but not the best for that power range...

20G won't be a 400whp daily driver, it's ideal for 350 -375 with barely any lag depending on supporting mods.
400whp on a 20g would require race gas and/or alcohol (or methanol) injection.

If you want 400whp on 93 octane then you're going to have to go very big and plan on all the necessary supporting mods.

i loved my 20g, hated my sz49. the 20g wont make 400whp on 93, but it'll hang door to door with a 400whp sti (sz49/green), not much difference until 5th gear. for me, the only turbos to really consider is the 20g or a gt35r, although the t3/t04s UR kit looks good for the price ($2600 kit).

Here is what I am going with:

TD06H-20G
PE850s
Walbro
APS Inlet
TGV Deletes
Big TMIC (installed)
Meth Injection (installed)
AP (installed and protuned)
APS 65mm CAI (installed)
APS Catless 3.5" (installed)

What do you think I will get with this?

well that all depends on if you get a mapped tunned for the meth. You could be hitting 400whp at around 24-25pis on meth injection and prob around 350-375 wheel on 93 at around 21-22psi. There was an 06 wrx wagon in PR that was running like 385whp and over 400ftlb to the wheels on a 20g and jdm sti tmic.

Inlet is recommended for any aftermarket turbo, as the stock inlet is restrictive and prone to break.

TGV deletes are not required, but are required if you plan on running a 3" turbo.

A 20G turbo Requires at minimum:

Stage 2 Setup +

Injectors
Fuel Pump
Large TMIC/FMIC
Tune

Inlet, Headers, Meth, CAI, TGV's, FMIC (If you choose a TMIC above) will lead to further power.

Make sure you have a good intake to support the MAF. Be aware of the Perrin Bigmaf. Your list looks good. Maybe some nice headers and good tuning makes the difference.

yes, Ultimate Racing makes an upipe for 38mm Tial wastegate. They can make it to fit for most downpipes. Better to call them before hand. If you have the money for ewg you should deff get it, helps control the boost much better. Not worth it to port the wastegate espically on the td06h because its not going to do much.
