I dont mean to sound stupid but whats the maximum safe boost for the stock turbo on the wrx im planning on buying one very soon and trying to research and where to begin with my mods and stuff. First is the turbo timer and down pipe so far any help would be great thanx

 

all stock its roughly 16psi

tell us your plans for the car and we will be able to better help you with what you want out of it, there are so many basic things you could do

 

Well basically i want to do turback exhaust probably apexi (down pipe up pipe) cold air intake sti intake manifold sti headlamps with HID, center gauge console with SAFC, deff turbo timer, further down upgraded turbo, 650 cc injectors fuel pump, rota tarmac gold wheels tein full suspension with possibly EDFC (prob not though) My goal is be track ready and off road ready...

 

sti intake manifold is worthless, unless you like paying $300 for red pipes.

with all that I would go with something like the TXS utec or an ECU reflash instead of a boost controller and SAFC.

 

the safc is a boost controller

 

no its not

I would say 15.5 is safe for the stock turbo with a stock uppipe i wouldnt run over 15.5 on stock upp because you will melt the cat in the turbo, then you wont be about to shift pass 3k
Safc is the fuel controller, Avcr is the boost controller
And sorry apexi doesnt make a downpipe or a uppipe for a wrx
Goodluck if you get one

 

as far as power is concerned the wrx has an extremely easy upgrade path. This is the path i've been following and will continue to follow ... tossing money into my car for the rest of my life. haha I'm 400 bones from step 5.

1) catless turboback exhaust
2) catless up-pipe
3) IC hoses or a new IC
4) gutted intake w/ high flow air filter (no CAI's)
5) engine management
The above combo will make your subie an Sti equiv.
6) upgraded turbo
7) upgraded injectors
8 ) upgraded fuel pump
9) upgraded fuel rail (protection from cylinder #3 issues)
** upgraded IC if not already purchased
10) retuned engine management
11) upgraded tranny/gearset
With all the above you'd be sittin at ~300awhp
12) upgraded exhaust manifold
13)upgraded bottom-end
14) blah blah blah
