It's pretty hard to read in the technical forums and the vendor classfieds right? Though, this question has probably never been asked before. 2005 sti? BPU? IDK!

I highly suggest you start reading:

http://forums.nasioc.com/forums/showthread.php?t=533787

Form your own opinions first. It's really hard to help you without know if you don't specify what type of performance you want (power, handling, etc). What kind of car did you drive before?

The AP is the best choice if you just want to plug it in and forget it. But if you like doing your own tuning then you can either also purchase Street Tuner, or you might want to check out the TXS UTEC.

it depends. if you plan on giong for a bigger turbo i'd buy the bigger turbo now, unless you're looking at a rotated turbo kit. In that case, I'd save up until I could afford the entire upgrade. if you're looking at just a bolt-on turbo, then you could probably install the turbo as well as a turbo back exhaust.

If you buy parts now and upgrade to a rotated kit later, you will most likely have to sell your downpipe that you bought and uppipe if you bought that as well.

if you still want to upgrade the car and you decide to get a rotated turbo kit (and thus save up for it), then I'd get STi Pink springs and some front and rear sway bars installed.

if you are just going for the bolt-on upgrades and stay with the stock turbo, I would get a complete exhaust and a tune from I-Speed USA (www.i-speed.us). If you have any money left over buy an intake to finish it off. If you do a complete bolt-on upgrade, you should see about 375hp with a good tune.

i personally think a tune from I-Speed is more valuable than an cobb accessport.

I'd get a turbo-back exhaust ~$1000, engine management ~$600-$800 (Cobb Accessport or TurboXS UTEC), Dyno tune ~$500, and some F & R Sway bars ~$300. You'll love the power and be surprised at how much better the handling is with just some sway bars.

If you get an intake, get tuned AFTER the intake, not before.

You will not see 375whp with *just* exhaust and a tune, sorry.. that's just not even close.

Save your money and buy used parts. Used TBE will perform exactly the same as new ones for all intensive purposes, and will save you almost 50%. Used AP is also cheaper. Check the user classifieds, ebay, and craigslist once you find what brand you want.

I would first look to buy a new turbo and TMIC, or possibly a FMIC. You can sell your vf-39 for around $300-400 and your TMIC for the same. Then I would recommend the SSAC TMIC and save even more.

This will free up some money for your upgrades.

So, now that you have a new turbo, IC, TBE, and an AP you should be running around $2000 net. A protune and some sway bars or springs would be next in line.

Thanks for all the advice... These Subi's are alot diff from what im used to.. On my Fox mustang, I could fab everything myself, from turbo manifolds, to intake (not airfilter intake) and even fab my own downpipes with just a mig welder.. From the looks of most aftermarket turbo's and downpipes, it looks like a lil more than what i want to take on in my garage starting to fabricate my own. I think for now, ill fab a FMIC and piping, buy a used downpipe, and fab my own catback w/ testpipe and catco highflow converter. probably use a UTEC for tuning, unless AEM has an EMS unit for the 05 sti (which i havent found anywhere online yet)

Consider driving the car a while and the answer(s) to your question will surface when you start saying, "I wish the car had.......". It will happen!

Consider a deadbolt turbo upgrade at some point, They behave like stock but flow higher CFM and are cheaper than swapping in a new aftermarket turbo.

But I agree with these guys, for starting mods:

Accessport
Turbo back exhaust
F&R swaybars are worth every cent
Leave your intake alone until you are ready to protune.
Don't get a blow off valve!!

Dont get a blowoff valve? Interesting concept.. I know they have bypass valves stock, thats all well and good.. But its been my experience between Vdub, and Mistsu's that oem bypass valves arent exactly the greatest.. I dont want it because of the sound.. I want it more for accuracy and reliability over the stock unit. Not to mention if i do go external, ill get one i can plumb a discharge off of, so its not venting right onto the top of the engine and intercooler. as far as sway bars and handling... They handle fine the way they came from the factory... and since its a daily driver/ weekend drag car, sway bars are last of my concerns...


Looking for power first.. handling and breaking later

"Are aftermarket BOVs necessary with Subaru turbos? No. The OEM BPV is perfectly fine up to 20psi of boost. For applications using higher boost levels, an aftermarket BOV/BPV should be considered."
