Okay, I realize I may sound like a complete moron asking this, but here it goes. Lets say you have a TBE (which I do), does that include the o2 housing, or is that separate? My TBE was already on my car when I bought it, so I'm not exactly sure about it, but I am pretty sure that they come separate. This is my first turboed car, so bear with me. If they are separate, ebay here I come!

Another quick question, and yes I did an "advanced" search on this, came up with a lot of good information, but not exactly the answers I was looking for. Lets say you had a completely stock car, except for a mail in flash. Bored with that you decide to get an intake manifold, and then get it flashed again for that. What exactly would be the whp increase on that? Also same question, except with a turbo manifold this time.

I'm sure some of you will probably say, "why get an intake or exhaust maifold as your first mod?" I'm just trying to see how much these parts will make over stock, because when everyone quotes numbers for these mods, it's usually on top of a larger turbo kit, which I'm not planning on getting for some time, so that doesn't really help me at all.

Thanks for your time.

 

Pop your hood and look down the side oppisite the battery and intake. The factory O2 housing should be a rusty hulk....and an aftermarket O2 housing will be (hopefully) stainless steel. (AVOID THE E-BAY CRAP!)

Also most (not all) aftermarket O2 housings eliminate a bracket which helps support some of the exhaust manifold and turbo weight.

If you get an intake ( I assume you mean an intake, not an intake manifold), it would be wise to get reflashed. More air needs more fuel to burn and a flashed ECU leans the factory settings a bit. But if you add more air like adding an intake, you need to supply more fuel as well, hence a re-flash.

Is is an absolute necessity, NO, but if you want to be completely safe, YES.

 

i dont think the ebay one is crap. not one person or thread complained that his has been crap or has cracked on him. buschur got 15whp from one of them.

second, if your adding an intake or fuel pump, it is necessary to flash the ecu. not an immediate thing though.

btw, are on the mievo.net forums?

 

Thanks guys! By the way, I already knew that for any of these "induction" type mods I would need a flash. That's why I included it in my question, and was wondering what the before and after would be from adding these parts. Also, I was referring to an intake manifold. If I get one it will be along side of an intake, all intercooler piping, and a reflash. But I was wondering how much whp the intake manifold would add. I was also a little curious about the turbo manifold as well, but I think I have seen it stated that it would give an average of 10whp.

As soon as I can I will check to see if I do have an aftermarket o2, but I'm currently away from home and my car, so it will be a while. I was just wondering if a tbe came with it or not, sounds like no. Just like elhalisf said, many people have gotten the ebay o2 housing, and I have heard it recommended left and right because of the $ vs. hp value. That's why I was going to go there.

Thanks again.

 

Oh yeah, I am not on the mievo.net forums. I actually haven't heard of them. I will be sure and check it out. Thanks.

 

I personally avoid the ebay stuff....some of the knock-off companies may use thin, cheap steel, crummy welds, poor fitment.


If youre gonna ebay, buy from a reputable shop or seller, remember, "buyer beware"

As for the intake manifold question, use the $$$ for some supporting mods like a fuel pump, boost controller, etc...

elhalisf <--------- I am on miEVO.net too

 

You would never do an intake manifold at this point. I don't know why you keep bringing it up. We can't give you HP estimates, because no one would ever bother spending that much money for such an unnecessary part with the stock turbo. You don't need a UICP either. A manifold is ok, but it won't make anymore power than a stock ported/coated manifold unless you pay big money for the Full Race manifold, which Buschur showed to gain about 4whp over the stocker...

 

Oh no, I completely agree. For just about anything I avoid ebay alltogether. It's just that I've seen many many people on these forums happy with their ebay o2 housing, and I haven't seen any complaints about them.

Oh yeah, and I also forgot to say that a boost controller, and probably fuel pump are going to be my first mods. I was just wondering what the intake manifold would do for me.

In case you're interested, my "to do" list includes: Boost controller, fuel pump, injen intake and uicp, buschur licp, o2 housing, turbo manifold, intake manifold, aps bov, maybe some 272s later on down the line, and last but not least a flash. Also some non power-adders, but I don't think that really matters. Actually I may go with an safc2 and learn to tune it myself, I haven' quite decided yet.

At any rate, I'm hoping for at least 320whp. I think that's not asking too much.

 

Werd warr, I knew you would chime in at some point. Thanks for the advice, I'll stay away from the manifolds for now then. Heck, I'm all for not spending unnecessary amounts of money.

Oh yeah, I kept bringing up the IM because every damn store I run into says they gain at least 20whp or some crap, and when I looked around the forums I really couldn't find anything.

Thanks man. Maybe I'll just stick with the "warr packages" until I can afford a larger turbo kit or something. I dunno.

 

Go with the Forge MBC, drop the intake, drop the uicp, keep the Buschur LICP, go with the BR coated tubular o2 housing, drop the turbo manifold, ported/coat your stock manifold, DROP THE INTAKE MANIFOLD (WTF????), purchase a BR ported/coated 10.5 hotside for your 03 turbo, drop the APS unless you just like to spend the money, get a Forge RS DV or JDM MR DV, go with the 272s, but forget the SAFC. If you want to learn to tune on your own, then get a real piggyback that can control timing. Or, get a flash and use the SAFC on top of the flash for minimal fine-tuning and the ability to tune for race gas at the track if you so desire.

 

You can't go wrong with my VIII package, but it doesn't mean it's the only good route. You could do my VIII package, then slap on some extra stuff from BR at the same time (LICP, o2, etc).

 

What aftermarket O2 housing has that bracket you're speaking of?

 

Cool, good info. Thanks man.

 

I'm pretty sure the Works cast o2 has the bracket, but it also costs $425. There may be others...maybe the Tomei o2, also.

 

Wow!! how many times have you quoted a product of your sponsors? i believe it was 5?? btw do you get money saying their name each time, because thats what it seems like
