Feedback On GSX Setup

First off, I have done plenty of research on the different aspects of my setup as well as different profiles of people with similar times as my goals. I'm hoping the mods below will get me to my goals, and from the research I've done I think they will. However, this is just a rough draft (for lack of better term) of my planned setup.

actually thats not a bad idea. if anyone in CT wants to buy my megan exhaust for what i payed with the shipping ill install it for them. its a turboback. the only thing we will need is a test pipe from megan or a hi flow cat. i can call them up and get it.

 

[glenneclipsegsx]

to the best of my knowledge when i talked to megan tuesday they were selling the 2g awd turbo backs. as for the rnr i dont even remember what they look like. you need to run the o2s for the car to run right if that helps. i payed a little on the high side for my cat back 450$ shipped which is cheap but high for what i think they are going to sell them for. plus the downpipe was 170$ shipped. but i bought it from www.thespeedfactor.com. im a little upset cuz they told me it was 450$ for the turboback then i got the catback and was like wheres the downpipe. they then told me that ooo there was a bidding war on who got the prototype and what not so that was the price on the catback or something. it sounded kind of shady when i called Megan. Megan told me they had the 2g awds done and where already in production and speedfactor told me that they had the prototype and Megan was waiting on me for feedback. but at any rate i got it. its all computer TIG welded; perfect welds. all polished piping, even the flanges are polished. not to mention you get all the gaskets and bolts you need. there is also two adapter pieces one to bolt up a stock downpipe and one for the 3in downpipe. im very impressed!!

A more common solution for wideband sensors is to mount the wideband O2 in the rear O2 bung.

 

[Shane2GSX]

Okay, so the wideband O2 needs to take measurements from the rear 02 instead of the front? It only needs to measure one and not both? If I get a turbo back with an O2 eliminator I can just plug in the wideband O2 where the bung is? I appologize for the newbiness, again.

 

[glenneclipsegsx]

Shane buddy let me break this down for you in easy to understand terms

-02 eliminator means the o2 housing is part of the downpipe(you probably dont want that if you in the future want to switch to a full garrett turbo setup)you will then need to purchase a new downpipe and 02 housing

-with the stock computer inline you always want both o2 sensors plugged in. They are critical to making the car run good. THE REAR O2 AS WELL!!!! It does check to see if your cat is working but it also uses the values to help the computer make its air fuel adjustments against popular belief

-you have two choices with the widebands
1)a narrow band /wideband sensor can be used in place of the stock leading sensor. this will allow the computer to read the narrowband for engine paramaters and you will be able to view wide band o2s on your gauge/device
2)simplier and cheaper option when u get your turboback exhaust have a bung(where the o2 sensor is probed into the exhaust) welded on to it close to the beginning of the downpipe (better readings the closer to the engine you get ). This will allow you to keep your stock o2 sensors in place and take measurements from your wideband in a separate location

Good luck

glenneclipsegsx:

Since I dont' know what turbo I'm getting, I will not get an O2 eliminator.

I believe I'll get the PLX-250 or 300 (not sure what the differences are but the 250 is cheaper) to read both narrow and wb. I can just use it to replace the front O2 and it will read both. This is a bit more expensive than option 2, but I like the simplicity. Plus it has a digital readout which will save me from buying a gauge.

Thanks for the help.

 

[glenneclipsegsx]

what is the difference between the two PLX units? IM not familiar with the PLX units.

 

[Shane2GSX]

The only difference I can see is that the M-300 has the bosch digital display and the M-250 does not. Other than that they appear to be the exact same and have the same features.

I will probably opt for the M-300 so I can see what's going on.
