    My new 2006 STi

    Listen I am new to the Subaru World, I know the basics, that almost every tuner know, maybe a little bit more, but I need some opinons from people who have already gone threw the test phase(product wise).I need to know the do's and the donts of mods on the sti. Keep in mind I have a 2006. I just purchased my greddy turbo timer, I am currently looking at a HKS Spec II B.O.V. and a F.O.R.G.E. Bov. I heard greddy bovs leak like crazy! I really need to know what kind of turbo back exhaust to apply. Any thoughts? i would really like to keep all one brand exhaust system! So i really want a turbo back not a cat back with out spep. down pipe etc..!

    Please list begining mods by brand...thanks...Feel free to email me personally at DjLetDown@gmail.com!

    Thanks Mike!

    well, with oil and water cooled turbos, the turbo timer really isnt necessary. the bov really isnt the best thing for your car either. in terms of exhausts, just anything catless. engine management is a must, a proper break-in period is also a must. welcome to the boards and good luck with the car. just whenever you think of doing something youre not sure about, hit up the forums man.

    Welcome Mike and I see that your from CO. A lot of people on this forum disagree with BOV's and believe that turbo timers are not necessary. As for the exhaust question, you should look into companies such as APS, Helix, HKS, Invidia, Daddy's, etc. The list goes on and on, they are basically all the same except for advantages and disadvantages here and there. You should go with an ECU upgrade before any exhaust parts. That's just what I would do. I hope I was of some help to you. For colorado awd owners, www.awdpirates.net is the place to go.

    Welcome!

    Turbo timer = not needed, but not gonna hurt anything.
    BOV = bad for the car, not needed, annoying, save your money.
    Exhaust: TurboXS, Daddy's, others mentioned, etc etc, all good. (ERZ is kinda ghetto).

    Check out TurboXS UTEC, Cobb Accessport, or ECUTEK for engine management. The stock ECU is restrictive and will fight any mods you get w/o one of those EM's to help. Only issue is that the '06 ECU is different, im sure, so you gotta wait for them to figure it out.

    Oh and have fun w/ your car!

    Congrats man...I just got an STi as well. Advice..if you want the most power out of whichever exhaust you get, go catless. I just ordered an Invidia Race exhaust, just straight pipes with no resonators or cats. Thats the way to go! Here are a few websites that may come in handy with your modding...enjoy!

    www.gruppe-s.com

    www.rallysportdirect.com

    www.jscspeed.com

    Most subaru owners are very pleased with those 3 websites. I myself use rallysportdirect becuase of the excellent customer service.

    Welcome and congrats on your purchase. As others have noted, a turbo timer is really not needed, and a BOV, well...to me that is a more a choice in noise as it is not a performance adder and has been demonstrated to invoke rough idle/slight fuel issues on STi's. Nothing to be afraid of, but if you get one, at least consider a fully adjustable unit that can be recirculated like the stock BOV. Then you can have your noise when you want it, and all available power when you need it.

    Before any performance mods, you should prep for them with the proper gauges and brake setup. Minimum, EGT and Oil Press., and if possible a wideband A/F is excellent and will serve you well if you go the tuning route later.

    After gauges and brake pads/lines, Engine Management should be first on the list, followed by a TBE. Be aware that a full catless system may cause your car to boost creep into fuel cut, and this is not something you want. This does not happen on all STi's, but it appears the closer you are to sea level, the easier it is to occur on a catless system. To stop it (if it does occur), you'll need either a DP with high flow cat or a porting of your wastegate.

    Read the stickies and use the search tool and you should be able to answer any questions this posts bring up. Good luck!!
