    Ok here's my deal shortly i should have around $1000 dollars to throw at my car. Now here are things i'm concidering:

    1. TBE probably Invidia, the V2 DP and G200 Cat back like what Dream has. I really like the sound and right now my STi is bone stock and I want something to start setting myself apart from teh bone stock crowd. My only concerns here are if i go with no cats at all will boost creap be a real issue?
    (estimated cost $1000)

    2. AP with Stage 1 flash. (estimated cost $650)

    3. Spend a few extra bills and get Tein coilovers, sand blast my rims here at school myself and paint them flat black on the cheap or maybe have them powdercoated. And tint my tail lights. (Estimated cost $1700)

    What do you guys think?

    AccessPort used = 500 - 600, just make sure they un married the thing.

    TBE = 800 - 1200 depending on brand. If you like Invidia, go for it.

    I would do the AP before anything else really. You don't want boost creep.

    I like option 3, but with a different brand of coil-over.
    JIC, Cusco, Whiteline, ETC... JIC offers some nice coil overs that don't cost much more than the Teins.

    I was under the impression that boost creap was caused by the turbo flowing more than normal because of the lack of back pressure from the exhaust. Does the AP account for that?

    And about the coil overs anyone else wanna wade in on the subject I was under the impression that Cusco was significantly more expensive. I just looked at the JIC coil overs they look pretty nice. What about them makes them better? Readymix i know you have Teins what are your thoughts on them.

    I like the Teins. They were great canyon coilovers. And with you being in San Diego from time to time, they may serve you well on Palomar MTN. For a California car, they definately make for a decent on-road coilover. Minnesota, not so much.

    IIRC, the AP can't compensate for boost creep. You'll need to get your wastegate ported or run the stock muffler. There's a big thread on Nasioc about boost creep, I think it's a sticky in the 2.5l forum.

    The biggest problem with the teins is that they rust. big. instead of using a material that is anti-corosive to begin with, they go a cheaper route and use a mild steel with a powdercoat.

    While that may seem reasonable, it has two problems.
    1. The powder coat chips away.
    2. Their not powder coated on the in side. This is the big problem. moisture gets in around the seals, and begins to eat away at the strut from the inside. most people don't even know it's happening until it's too late.

    This is a pretty standard thing. moisture gets into most coil over systems, with the exception of rally built and high end models (Whiteline G4s), but most other companies use materials that don't have such strong tendencies to rust.

    JIC uses either aluminum or stainless steel, Cusco is exclusively AL(Hence $$$), even Tein uses AL on their higher end systems, and those models are ok.

    When you go cheap, you loose somewhere. Be it fitment, reliability, longevity, etc.. somewhere your going to loose. if your just trying to lower the car aesthetically, get some springs and be done. if your out for serious hanling upgrades, don't cheap out.

    If you get the Maddad V2 downpipe you won't get boost creep due to the divorced wastegate design. I went with option 1 myself as my first mod and didn't have any problems because of the downpipe. Then I followed it up with Cobb Stage 2.

    I got boost creep with Cobb Stg1(AP+CBE) at WOT in 5th and 6th. Boost creep went away after I added an Invidia Divorced Wastegate DP and bumped the cobb up to stg 2 LWG. Something similar to Krees23's or my setup should take care of that problem.

    Ide save alittle more cash and get the TBE and the Accessport all at the same time. As for the creep, some people get it, some dont. I had that problem with my VF39 and had the wastegate ported.

    Yeah i was thinking about doing that ^ because i'll get a little bit different sound it'll bolt right up to my stock catback i don't have to worry about creep and i will still be able to paint/powdercoat my rims AND i'll have more power due to the AP and the DP.

    As for the Teins i know i must seem like a cheap bastard doing this but do you think it'd make a difference that i'm oging ot be living in San Diego since it doesn't rain much there. Or will i still have to worry about corrosion. Cus right now from what your saying i'm kinda leaning towards the JIC coil overs cuz I am looking for the drop because of look but i'm also interested in handling ultimately, and if it's gonna save me money in the long run i'll go with the more durrable coil over.

    Thanks for all the replies guys this is great!

    Oh one last thing, how does the divorced dp keep you from getting boost creap? Thanks guys!

    the gasflow out of the w/g is kept from joining the main flow untill later down in the pipe.
    makes it less likely to getinto that path of less resistance feedback loop.

    Discopope i'm not sure i quite understand, if i understand what you're saying correctly then wouldn't keeping the two flows seperately woudn't it cause the turbo to flow more thereby causing boost creap. OR are you saying that the waste gate will flow better because of this thereby eliminating boost creap.

    and wrxboy2003 touche! haha

    It doesn't. I have yet to see any conclusive (read: properly documented and containing a significant sample) evidence that says a divorced gate will eliminate creep. Just because it helped someone (or 2) does not mean it will help you, just too many unknowns. As for me, I ported my wastegate at the same time I did the Stealthback.... A little intimidating, but I didn't have any problems and worked like a charm (although I didn't know that I would get it anyway). Note that it is definitely related to temperature and loading. I think the biggest variable is where people live, and we are in a bad place to try to cross your fingers it will not happen...

    "Temperature related" ...I should have said that it occurs at cold temperatures; watch your boost gauge when it is 0F and again when it is 90F...

    Check out Sogonergs thread in the Vendor forums...He's got some decent deals on the AP and some TurboXS stuff...
