I finally got a evo 8!
but afraid to take it to the dealer way it is right now!
I have located the stock BCS tied up with some wiring by the driver side headlight.
currently the evo is running on the turboX boost controller! with two hose.
one looks like its coming out from wastegate and other from the turbo area(boost source)
I'm not sure where these hose will go on the stock BCS?
if its that easy! is there some other hose that needs to be hooked up?
I already looked at the boost controller install but nothing on how to put it back together.
again! i am new to turbo and the evo only has 6000miles on it!
I am taking it in because of the engine service soon light!
other than this mod, the evo only has Injen intake and greddy turbo timer!
thanks in advance!

It should be alright. I took my car to the dealer with a MBC and a teast pipe and the did not say anything.
Anyways, if you really need to go back to stock, the hoses are like this;
Remove your MBC and all it's hoses.
Get some 4mm vacuum hose.
Tee a line from the compressor housing to the wastegate.
That will feed the bottom nipple of the BCS.
The top nipple will feed back to the intake.
Did you keep you stock hoses?
You should be able to go to a Kragen, Auto Zone, or Pep Boys and have the code read for you too.

Well, i took the MBC out and plug the two hose (one from wastegate and other little above by the turbo) into BCS.
I was told that as long as outlet on the BCS is hooked up to compress pressure, it should be ok.
just have to make sure the one from the wastegate is hook up right! to the inlet!
so which fitting on the BCS is the outlet and which one is inlet?

There should be a vacuum digram under the hood of you car too.
PM me your email address and I can send you that section of the manual.

the factory vacuum line should be hooked like this. you'll have a short piece of vacuum line from the compressor houseing to a t-fitting. in there you should have a restrictor pill. then another short section of vacuum line should be ran from the wasegate acuator to the top of the t-fitting. then you'll need a section of vacuum line to run from the other end of the t-fitting to the bcs. connect that to the fitting on the bcs closest to the front of the car or closest to the electrical connection. now take another section of vacuum line and run it from the intake tube to the other fitting on the bcs. I can post a diagram of this if you need.

i think you're being anal. what are you taking it to the dealer for?

example... i just went to the dealer with my extended warranty on my gsx to have my tranny replaced. i had an act 2100 on there and a turbo back exhaust, intake, bov, etc etc. they were like "you know, you really should have a stock clutch." and i was like "look at the insane things people are doing to evos and you still service them." and they said "yeah, its ok. don't worry about it."

besides, if you just tuck it away, then who cares? as long as it didnt cause the problem then they cant say anything.

You have a lot to learn in a very short time Jive! Mitsu has become notorious for warranty denials on the Evo for almost any mod, but ESPECIALLY an MBC. I take my mbc, bov, and s-afc off every time I get near the dealer...

it was my understanding from a mitsu USA rep not too long ago that the modified part in question actually has to have been the cause of the other damage in question. the owner of a local dealership wanted to put modifications on some of their evos to jack up the price a little bit. basically, if you put on a manual boost controller and a strut blows up on you they cant deny the warranty work. but if you have a mbc or other tuning mods and your turbo blows up or your engine goes, then they will trace it back to find the most likely cause. they know the evos are a modders car and as such, they cant go arbitrarily denying the warranty. you can however have a specific part of the car blacklisted in their system if they see a modification that could potentially cause damage. that was about 6 months ago, so i dont know whats changed since then, neither do i know the particular level of anal behavior your dealer exhibits.

maybe i just have cool dealers in my area or something but none of my friends have ever had a problem, and neither have i. actually, come to think of it, a local dealer installed my friend's s-afc and his big 16g on his GS-T.

Not only is that not normal, but that dealership is possibly in the lowest 1 percentile. ONe dealership in the DC area is so bad that the entire DC Evo Club put up a boycott. There's a permanently stickied thread just to warn everyone in the area. OF the 5-6 Mitsu dealers in the entire surrounding area, only one is worth going to for service if you have ANY mods.

What that Mitsu rep told you is true per the LAW, but very rarely is it followed, because we as consumers have no recourse if the dealer violates the Magnusson-Moss Warranty Act. To pursue it, you have to get a lawyer and take legal action, which is time-consuming and expensive. Somehow, Mitsu is getting away with shafting 90% of its Evo owners...

that is unacceptable. if a dealer denies your right to have something fixed, then you need to call up mitsu of america and inform them that not only are you going to sue them if they dont make the dealer do the work, but you are going to file a class action lawsuit against them for denying warranty work arbitrarily. what they are doing is illegal. you have legal rights to have the work performed otherwise they should knock a few grand off the cost of the car to make up for not having a warranty in the first place. i know that mitsu is in financial trouble, but they need to learn that screwing their evo customers is not a good way to make up for it. mitsu's business ethics are the only thing holding me back mentally from getting an evo...

edit...
i just looked over my warranty sheet for my car and apparently i have extra rights because i live in NY. not sure how many of them would apply to this type of situation and im too tired to re-read it and cliff note it here. maybe that is the difference between the dealers... legally, in ny, they gotta do the work.

You're preachin' to the choir, man. People _HAVE_ complained to Mitsu of American and filed class action lawsuits, but it's not paying off. The dealers ARE required to do warranty work, and they can only deny it based on an aftermarket part if they can PROVE that part caused the damage. The problem is that they don't ever really have to prove it as long as there is a reasonable doubt that the part in question COULD have caused the problem. Maybe you'll be luckyin NY, but it's atrocious everywhere else in the country...

well, i guess the nice thing about the evos is that you dont have to do much to get them into higher horsepower areas... not like the dealer would notice if you had the ecu reflashed and then you could always take off the intake and the exhaust and mbc and be all set... bring it back home and be at like 350 horses again.

Actually, they can detect a flash on 05s, which is why I haven't gotten one. I also take off my mbc/bov/safc, but not my cat-back, because my dealer said anything after the cat was fine. I don't believe in replacing the stock airbox on the Evo, so I just have a drop-in filter, which doesn't require any extra time, but what you said is about how I do things.
