Stock location turbos? Recommendations?
Hey fellow i-clubbers -
I am contemplating upgrading the turbo and a few other things on my 07 STi and am looking for a bit of feedback/advice from anyone here.
I want to keep the stock location for the turbo, and keep everything as stealth as possible. I've been reading around, and from what it sounds like, Tomei's ARMS M7760 might be what I am looking for.
Does anyone have any experience with their turbos? Any other recommendations for a stock location upgrade?
The other items I would be looking to upgrade at the same time would be:
Injectors
Top Mount
Turbo Inlet
E85 tune (possibly, there are hardly any pumps in the area which is whats holding me back)
I currently have the following:
SPT Intake
Titek Catted downpipe
Greddy Evo 2 catback
Walbro fuel pump
Tune from Mike @GST via Accessport
Thanks for the input!

just get 1000cc injectors and an e85 tune if you can swing it. Most hp/dollar no contest.
Tomei is overpriced jdm IMHO. Not a fan of 3" inlets either, as they fit like *** and have an absurd offset that is way worse that the 2.4".
Get a bigger topmount and go blouch dominator (2.4") with 1000cc injectors for a 91 tune.
And if you are nice to the oem inlet, it should be fine. I actually got mine out and in without pulling the intake mani by removing the power steering pump and being careful; I don't see any reason to replace it unless you rip the rubber sleeve. The hard inlets are super *** to fit, doo-doo butter status.
just my opinionz

I am really considering the E85 tune too, it just sucks that the closest station is in Hayward and I am in the Oakland Hills.

Ideally I would like to get to the 350whp range or so on 91 if possible. For spool I would like something relatively quick, not terribly laggy, and smooth.

I had a Dom 3 on my car as well but I don't think you will like the lag, its nothing TERRIBLE, but it isnt reaaaaallly relatively quick either.
Slap on an EWG and the right supporting mods, and you are good to go.
Although I am not sure about hitting 350 to the wheel on Cali 91, I am used to Texas 93 where those numbers are possible.

I have the Tomei Arms turbo and I love it. I'm not sure if there's better options for cheaper, but I like the reputation that Tomei has. A lot of turbo manufacturers have a lot of good and bad reviews, or a lot of fan boys and haters. Tomei seems to just have fan boys 
. I've seen it be compared to a 20g as well as smaller versions of the RX6 turbos.
You have plenty of options since you have the 2.5L motor, and lag shouldn't be too much of an issue because of it. I was making almost 300whp on my old 2.0L with a quick spooling turbo (VF-35), so 350 with the 2.5 should be pretty easy.
If you're doing the turbo inlet, you may as well do the TGV deletes. It'll help the fitment of the inlet a little bit, and give you some extra power.
I was looking at the Killer B manifold, since it's 321 stainless, it won't ever crack like most other 304 stainless, but for me it's too much $$$. It comes with the UP too if you want one, I forget if the '07 STi is catless UP.
For the injectors, you should talk to Mike. A lot of tuners prefer specific brands, since each one has their own nuances. I know my tuner hates Power Enterprise injectors because they're 2 stage or something like that, and loves RC injectors.
