i just bought a TBE for my evo ix and i wanted to know if i can put the complete TB on or should i just put the cat-back on until i get a tune?

 

yes it is fine.

I hope you have a boost gauge to monitor the boost and I hope you have purchased a MBC to control the boost.

Without those two things I would not recommend a TBE.

Lastly, I would suggest that you search before you ask a question that has been discussed over 1,000,000 times.

Oh yes put your flame suit on after this.

EDIT: I suggest that you search before you make another post as this was your first one. I also suggest that you read the site rules as they speak directly to this type of posting.

 

The guy above is being a bit harsh, I'm sorry. It's people like him that make this forum an insultment foundation and not a helpful forum. When you install the TBE, make sure you put the O2 Sensor fix on the O2 bung in order to prevent a Check Engine Light. Nothing bad will happen from this, it's just annoying to have the CEL. I had my exhaust on without a boost controller or boost guage. Just get it tuned for the best results.

 

What was harsh about what I said?

With a TBE you will increase flow/ decrease back pressure and thus increase boost.

I simply suggested that he purchase a MBC and boost gauge which will gaurd against anything wrong happening.

Also this was his first post, and it is obvious that he did not read the site rules nor did he search as this question has been asked more times then I would like to read.

To the op:

TBE without tune ok.
Boost gauge and MBC not required but are highly recommended.

 

Why do you say to get a boost controller??? Will a TBE increase boost to the point you have to turn it down or something?

I've heard of many people running a TBE without a boost controller... that's why I ask.

 

Ok... "highly recommended". Disregard my previous question.

 

I have NEVER heard of the boost creeping on a stock ECU. If anything, it will pull timing and lower the boost because it detects something awkward.

Btw, are you a cop? You seem like a cop with your "rule" analyzations. Does he deserve the electric chair for posting on a forum to inquire something?

 

...varrius good point

...the CEL fix is definitely recommended...I got one from eBay...do a search on the forum and they have a link for it...

...dont worry we are all new at some point and we all have a million questions...some people just are more grumpy about questions being asked...he was not being too harsh just suggesting that you do a search in the future...

...have fun with your new TBE...

be more helpful!

its fine to just instal the tbe dont worry go ahead!

 

With an 03 Evo with a 3" downpipe, cat, and 3" catback will maintain about 1.4 bar pulling in 4th gear with 100 octane gas. Not boost controller or electronic mods. I've been running this way just fine for the last 3years.

 

I would also recommend you get a boost gauge and a mbc when installing the tbe. When I installed my tbe I had to also add a boost controler because the boost was spiking to 25psi.

 

I used my TBE and did not have a boost controller.....but i did have a boost gauge...nothing bad ever happened

 

you'll be fine. but with the tune you'll get the most power.

 

Newbie03 is correct on everything; Varrius is terribly wrong and does not know what he's talking about. Racerx's info was not relevant when mentioning 100oct.

1) Yes, TBE without a tune is fine - I'm not sure why you'd ask about doing just the cat-back vs the TBE - not sure where that came from.

2) The TBE costs twice as much for half the power as a flash - it won't be useful without a tune on your IX.

3) Yes, doing a TBE reduces backpressure which can fool the ECU into causing a much higher boost spike and higher sustained boost. This can lead to dangerous conditions and/or cause fuel cut, which is highly annoying and leads to an overboost CEL. It is not recommended to install a TBE without first installing a boost gauge. Anyone doing so is very foolish.

4) Likewise, to get the true gains of the TBE while ensuring your boost is properly in check, you should install an MBC along with it and the boost gauge.

5) Yes, the rules clearly state that you MUST search before posting a thread.

 

MRevolutionRed,

Not to trump anyone thats already posted, but you have a MR. Before you install the turboback, pay careful attention to your boost gauge (it most likely will be spiking around 1.3-1.4 bar) Make sure you note this and check it again after the TB install to monitor if their are any changes.

I just recently installed a TB on my MR and did the same thing. The MR gauge is not the end-all-be-all gauge but it should suffice for now. I notice more pull through the top end and harder pulls in general compared to stock, but the boost is still not spiking past 1.4 bar so this is most likely due to the taper. That being said, a MBC and tune are the next mods you should do if you plan on keeping the car at a Stage 1 build.

I'm local (Warren), so let me know if you have any questions and I'll do my best to help.
