Here's my quote from Jotech. As I am sure all of you know it is owned by Kenny Tran and they do great work. Let me know what you guys think.

No offense, but you really need to sit back and research some more. That's an incredibly outdated poor performing turbo kit and an outdated FMIC. That turbo is fairly small for an STi and I can't imagine paying that much for a turbo kit that won't perform. You should check out the Ultimate Racing Stage 3 kit or Greddy T67 kit instead. An uppipe will be practically useless as well as the STi has no catalytic converter in the uppipe like a WRX does. Moreover, the price on that HKS Carbon Ti($899) is fairly high.

No offense taken. I thought the prices seemed a little high that's why I put it out for everyone to look at. I just go on the TurboXS site and realized what a better deal their stage 2 kit would be. The UTEC seems unreal. I can't imagine a computer adding 30hp but I hear so much about it it must be true. I'm definetly going to get the XS UTEC but I am so torn on exhausts it's unreal. The XS TBE seems good but I'm also thinking a Perrin downpipe and the HKS titanium. I will also be getting front and rear Cusco tie bars.

Check your PM's. Personally, I wouldn't do the UTEC either unless you plan on tuning your car yourself or having TurboXS tune it. The UTEC is a very capable engine management system but its not very practical for every day driving. The UTEC doesn't adapt too well to changing weather conditions(whether this is the fault of the tuner or of the UTEC itself is unknown...probably a little of both). A close friend of mine tuned had his car tuned on a dyno...next day its knocking. He takes it back..the tuner fixes the tune...it knocks the next day again. Finally he just got fed up and switched to an Ecutek reflash(what Prodrive uses in their Subaru WRC car). From there on in, no problems. A reflash on a stock ECU(what the Ecutek is) can adapt much better than the UTEC to changing weather conditions and is actually much cheaper. Personally I think the UTEC would be a bit overkill for just a TBE. However, if you get your car tuned at TurboXS I doubt you'll have any issues. They know the ins and outs of the UTEC better than anyone and, as you can guess, can do a better job tuning it than anyone else.

By the way, All 3" TBE's should perform nearly the exact same. To make your decision I would do it based on sound or price. There are a lot of sound clips of different TBEs floating on NASIOC. My personal recommendation is the B&B TBE.

Thanks sacchin,
What do you think about a Vishnu downpipe and an HKS exhaust. To me it sounds like a wicked combo. About the Prodrive Ecutek. It sounds to me like your definetly right concerning the issues with the TurboXS kit. The only problem is that I don't know how I could get them to reflash my stock one without having to take mine out (obviously) and not have transportation for at least a week. The Cobb Rally Car is right down the street from me as well as the guy who built it. I think I'm going to go get his opinion on install and such just to build some relationship with my dealer. If there is anything else I need to know as far as upgrades let me know. I just got my STi and I am new to the whole Subaru thing. I've been doing imports for a while but never a Subaru. I'm a blank canvas as far as Subi upgrades go.

i see your pretty new at this, how about you tell us exactly what your looking for and we can recomend some brands. or if your interested in reviews, we have reveiw sections, and also the search bar is very helpful. u can get many answers from there.

as far as my opinion for easy power... turboxs makes good prodcuts but if you dont want to deal with tuning yourrself, cobb tunning accessport, you really cant get any easier then that. as far as exhaust options...... if you want loud go with turboxs..... i have a prodrive axleback (oval tip) with the helix uppipe and turboxs stealthback. now the turboxs still has the 4inch bellmouth downpipe to the 3inch pipping. awesome gains and sound. as far as other tuning companies, Ecutek is good. also you cant go wrong with titanium exhaust such as JIC or magnaflow and other companies. now if you really have other questions please use the search, you will probably find more answers, and quicker. the nits and bits you can post

Thanks for the help to everyone. I know I am new at the STi stuff because I've had it for less than a month. I have decided on the Vishnu TBE, Cobb Accessport, Blitz BOV, Cusco front and rear tie bars, STi pink springs and probably whatever intake Cobb recommends. I'll also be getting a turbo timer just for the turbo sake to reduce coking. I should have this stuff all on by February. I'll let you guys know how it goes and I'll be reading up on my Subaru lingo. Thanks to everyone.

The Blitz BOV is a bad idea. You'll run rich inbetween shifts and most likely have problems idling. Not to mention the fact that the Cobb accessport isn't made to handle an atmospheric venting BOV. The Vishnu TBE is nice, but a good $500 more expensive than its competitors and IMHO isn't worth it.

Thank you. I did not know that about the BOV. Is there any I can run and not run rich and have it Accessport compatible. I am getting the Vishnu simply because it's something a little different from the norm. As a fellow car enthusiast I am sure you can understand that. I don't want to model EVERYTHING after something everyone else has done before. Thanks man, I really do appreciate your help.

Sure thing. The accessport is convenient but for the most part if you want the most out of your engine management you should probably get a tunable engine management system--and once again I shamelessly plug the Ecutek. In your neck of the woods, I would recommend Al@Dynoflash(he's tuning my car in two weeks). For $750 you can get an ecutek reflash with a full road/dyno tune by him and you'll probably see 20hp more than an accessport. Plus you can also run an intake if you want to. In reference to your other thread--intakes usually work by leaning out your air/fuel ratio so Cobb doesn't recommend their use with the accessport. However, I would talk to Cobb about using a K&N Typhoon intake if you really want an intake as it does not change your AFR at all. Personally, I wouldn't do an intake as it won't show any real gains and for the $$$ it isn't worth it. I'd definitely toss the $80 in there for a Walbro fuel pump. The stock fuel pump will be pretty much taxed and its a good mod to have even though you can't see its effects.

In terms of suspension--buy a whiteline 24-26mm adjustable front sway bar and set it at 26mm in addition to the pink springs. You won't regret it for a second. It will reduce understeer significantly.

I like the convience that the Accessport offers as well as its variable functions. Not to mention I can start with it and always upgrade to the Tunable version that is coming out (both work in cohesion). Who is this "Al@dynoflash" and where is he located. On reason I am seriously looking into the Accessport is because of drivablity reasons. Weather is completely uppredictable in New Orleans. It goes from clear skies to typhoon status rain in 5 minutes. I hear so of these reflashes give you serious hell in inclement weather. I guess the real reason I'm stuck on Accessport so far is that there is no down time, it has many functions, it's user friendly in the sense that anyone can use it and it's good on the car (can return to stock anytime). Let me know what you think about this.

Hi there. Welcome to the club! Glad to see you already caught the mod bug. First, read this thread. Then, read the rest of the Threads of Note in the sticky in this forum. Then, read the stickies/threads of note in the other Impreza and Joint Technical forums. these will answer most of your basic questions, promise. Then, when you have more specific questions, post 'em up.

I used to live in the DFW area now I'm in New Orleans but I would drive my car out for a week. Thanks for a good link in Austin. It's closer and they specialize in STi's (at least more than Jotech). I had a 98 Honda Prelude before and they did a great job with a turbo install. I am calling Cobb and Vishnu as well as that shop in Austin today about installs. My big concern now is the WG issue. I don't see much info on the 05 STi so I'm kinda worried about getting into something that will make me miserable. I really would like to use a Vishnu exhaust with the Accessport as well as several suspension mods (i.e. Pink Springs, Whiteline or Cusco sway bars, etc...) I will definetly call them and see what the low down is. I'll be glad to see the 05 year progress so we can start getting some solid theories on modding the 05 STi. BTW, I've got to say that this has got to be the most professional, knowledgable site I have seen the entire time I have been into cars. PERIOD.
