Whats up Fellas!
Bought a New 2006 WRX about 2 months ago, looking to speed somethings up, was looking at either buying a BOV, but have heard how much a pain in the ass they can be and if you dont properly tune them, they are crap. But also was considering putting in the intake which i know would be a imporovement.....any suggestions?
Also does anyone know any real good, decent priced, intercoolers, cause the stock one looks like garbage...compared to the STI model, and the aftermarket ones available.
save you're money for a Turbo back exhaust and some good engine management like Cobb AP or Utec....as anyone here will tell you, intakes don't do crap for our cars till you are putting down ~ 300 whp, and the stock BOV is great until you are hitting above 18lbs of boost wich most of us will never see, and even then there are no real perfomance gains...just a psshhhhhh

I've experienced both of them...Save your $$$ and buy.....
Stock exaust system
Now you know where I stand
Stage II and loving it!
You might want to read the Engine Modification sticky. Generally, those two mods (with no other mods) will net no gains and possibly hurt your car. To each their own though, its your car. I opted to upgrade my suspension first, when I decide to do power mods, Im going straight to stage 2 (AccessPort and TBE) Which should get me a nice gain in speed.

Thanks your responses have been a great help because when it comes to this, i have no clue, but just love to drive and have the greatest respect for my car. The Cobb AP, i checked there sight, it handles engine management, but i really dont understand fully, could you possibly explain it uses and benefits, for this dumb newby.
Also since i have a 06 i dont need the Uppipe, but supposedly i would need a HF cat (downpipe)...? Also any ideas on the intercooler, is that a good buy, or idea, or am i still barking up the wrong tree.....?
First of all, I'd wait on an intercooler and work on getting a turbo-back exhaust and some form of Engine Management (i.e. the Cobb AP).Originally Posted by INFARED
The Cobb AP is basically a mail-in tune. It's results are proven and it's a very popular mod. Most people buy a Cobb Stage 2 AP for around $600 and then find an aftermarket turbo-back exhaust.
Hmmm, I hope I answered what you were asking.
The Cobb AP basically takes over your stock ECU and re-maps the fuel, timing and boost curves for higher performance. Or a simpler explanation would be, it increases the boost for more power, but also increases fuel delivery and changes the timing so that the power is increased saftely.
To see any power gains from the AP though, you'd need to load the Stage 2 map from it (the stage 1 map doesn't give you much power, but does increase the driveability). To load the Stage 2 map, you NEED to have at least an aftermarket downpipe installed, but a turbo-back would be even better.
If you go to www.CobbTuning.com, there's tons of info on it - they even sell "power packages" with a full Turbo back exhaust and AP, but you might be able to save money buying the AP and another TBE seperately.
Intercooler you don't need until you upgrade your turbo, as far as I know.
EDIT: sorry for being redundant, I was posting at the same time as Heather

Everyone has said what you need to hear, dude. I also have an '06, and I really suggest you get an AP first, and spend a lot of time behind the wheel before you go for the TBE. The powerband actually changes quite a bit, when you flash the Stage 1 map. Despite the fact that you don't see very big HP gains, you do see a much smoother powerband, which makes driving much more fun, and you see more power earlier, which makes your car seem quicker.
Heather described the AP as kind of a mail-in tune. This is an apt description, except you don't have to mail it anywhere. You buy the AP for your model-year. It comes loaded with a few "maps" from Cobb, and you can download more from Cobb or from other places. Also, once you have a few more mods, you can take your AP to a tuner, and they'll write maps specifically for your mods.
It gets a little wacky regarding basemaps v. real-time maps, but if you read the AccessPORT manual, you'll get the idea. It's really simple to use. It's definitely the way to go, though.
You can get the BOV sound by taking out the air silencer. Your wrx allredy has a BPV(by pass valve) and i dose the samething that a BOV dose just for a car running lower than 20 LBS of boost. It creates the desired sound that you are looking for it is not al loud as a BOV is. My friend did it to his 04 wrx and it has created no problems to any part of his car. So you might want to look into doing this instead of buying a BOV and running the risk of damaging your car.
ya how do i do it??
any instructions in this forum? didnt see any
