I'm brand new to the site as well, although I've been looking on here for events to try and meet some of the community and maybe have someone activate my account for me. I actually went to andretti's last night but only got to meet a few of you, before i was sadly kicked out at 10 for not being 21. I'm 18, I drive an 02 obsidian midnight blue or whatever its called WRX. Located in marietta near Wheeler High School and the Big Chicken. So far all I have done to my car is lower it with eibach springs, tint the windows to 15%, and i was going to order a cai but read they need to be custom made, so instead i ordered a turbo XS RFL bov, and saving up for full exhaust. Can't wait to meet all of you.
Welcome to the site! A few words of advice: An intake does not need to be custom made, but it is also a waste of time. The stock intake is good for over 300whp, and an aftermarket intake will actually hurt performance in some cases. A BOV is an absolute waste. It will make your car run like crap (sputtering, and running rich), and you WILL lose performance with it on there. Basically, it is a noise maker that robs you of horsepower. Get the exhaust first, that is your best bet...
most of them are in black and white seeing as i didn't have any film but that. But my friends and i got bored and he wanted to take pictures of our cars so i let him use the camera. I have more pictures but since I didn't take them, i don't really like them. http://img376.imageshack.us/my.php?image=subyus6.jpg http://img385.imageshack.us/my.php?image=lol2bh0.jpg http://img137.imageshack.us/my.php?image=lol3iw7.jpg
Thanks for the advice, I don't know much about exhausts so when the time comes i will probably post some questions. Only thing i know is i like how the greddy evo 2 sounds. and some of the invidias. But thats all just sound.
Any way i can get a WRXAtlanta.com sticker, the semi-small white ones, my back window is looking pretty plain.
Welcome to the site! Truth about the exhaust. However, a properly adjusted BOV does not affect how the car runs much at all. On the throttle there should be no difference. The rich condition between shifts isn't a huge deal if you don't have cats. I've ridden in relatively mild cars with full atmospheric BOVs that ran great. Specifically, I have a friend with a wagon that is sporting a Turboxs RFL. It sounds AMAZING. It absolutely roars. I really want one, and will probably get one sometime soon. Hes also running a vf39, and his car is retardedly fast, and I didn't notice any hesitation between shifts when we were hauling ass down the freeway. The main problem with aftermarket bovs is that they're shitty and they leak. The turboxs one is known to be a great part from what I understand, so IF YOU ADJUST IT PROPERLY you shouldn't have any problems. Enjoy, cheers!
Umm....no. A BOV, no matter the "adjustment" is will effect the car negatively. The reason for this is because our MAF sensor is preturbo, and the BOV is post turbo. Therefore, our ECU is expecting to see the air that is being blown off, but is instead running way rich because of the massive loss of air. Now, a 50% recirculating/50% atmospheric bypass valve, can be used without as much negative effects, but the ONLY way with a STOCKish WRX/STi is to use a stock ByPass Valve, or an aftermarket 100% recirculating BPV. Please know your facts before you start trying to tell people what to do Bwaaaaaahhhhh PWSSSSH RICE!
oh snap! good kill. welcome to the site! I live in your area and went to Wheeler....many years ago. there is a wealth of information here...live it, learn it, love it!
Welcome to the site! My Invidia V1 Catless downpipe is for sale, as well as my Invidia N1 3" Catback. The exhaust is used and has a few battle brusies. The DP is in excellent condition, with one scrap on the bottom. Check the thread below. Pics may be up soon. KILLER PRICING for ASAP purchase. http://www.wrxatlanta.com/forums/showthread.php?t=21797
Excuse the threadjack, but I do know my facts. The MAF is only expecting that air between shifts. Between shifts, the blown off air is absent, yes, but the richest you'll normally go is about 9.1 (from what I've seen on other WRXs), which is indeed rich but not enough to be a HUGE problem. When you're cruising on the throttle and the BOV is closed, the car doesn't know the difference between a full atmosphere and a BPV. What I mean by adjustment is making sure the valve opens at the right point and is fully closed under acceleration. The main issue with running a BOV on these cars is that the air is vented into the intake AFTER the maf. Many cars vent it before the sensor, so the ecu is able to meter for the lack of air easily. Also this lack isn't massive compared to huge volume of air already going through your intake. I was simply saying that BOVs aren't the pure concentrated evil everyone makes them out to be. I don't think having one is particularly ricey, either. Sure its not the best performance investment, but they're fun and the right one sounds bitchin. Lets not become NASIOC, friends. If this guy wants a RFL, go for it! Welcome again! And for the record, I would advise getting a TBE and a tune as well. You won't BELIEVE the difference!
You can't go wrong with an exhaust either way. :naughty: The fact of the matter is that a BOV is not a performance mod. Unless you're pushing ridiculous boost, you really don't have any need to vent to atmosphere. I do admit, that if I had excess money (and had finished buying just about every other performance mod I wanted), I would likely pick up a 50/50 BOV. I don't care that it does nothing for performance, it just sounds freakin mean. I personally wouldn't ever go for a 100% atmospheric BOV just due to the fact that it might shave a pony or two off of your power.
get the exhaust first....get the BOV when you get the necessary modifications done to the car to necessitate NEEDING the BOV. boxer rumble > silly RFL BOV. fact of the matter remains that a STOCK WRX does not take well to a BOV like a different turbo'd car.
No shit sherlock... He is putting a BOV on a stock bugeye WRX. That means he still has the stock Up-pipe catalytic converter. When the car runs really rich between shifts, not only does it cause a stumble, but it also tears up the pre-turbo catalytic converter. When that happens, the cat basically chunks off and destroys the turbo, and possibly the motor (depending on your luck). Its not a performance investment at all. Not putting it on your car will prolong the life of your motor and turbo. Its that simple. Yeah, this isn't NASIOC, otherwise I would have just called you a moron and told you to search...
well if i buy Invidia N1 3" Catless turboback exhaust does that fix the stock up-pipe problem? sorry for being such a noob haha.
No, the up-pipe is completely different. You can find one for $75-$200 used. GrimmSpeed makes a nice one that you can coat. Read up on their product listing here: http://www.grimmspeed.com/catalog/p...ducts_id=79&osCsid=2p9kcr314oesf73u28fq6bn261 Oh, and if you are referring to mines, you will only get the catback. I sold the downpipe yesterday. Downpipe + Catback = Turboback
That cat will grenade itself eventually anyway. Don't forget this will also be made much more likely by a TBE and a tune. A catless UP should probably be this guy's first mod, regardless of any plans he has for the car. We know that already. I also never said a BOV was a performance investment. Its just that people run them all the time with little to no problems. I maintain that a quality bov when used properly is not the death knell of your car. And with reference to the pre-turbo cat, its probably not a whole lot more dangerous than the increased boost of a turboback and a reflash.
A catalytic converter should last over 100k miles. While using a BOV, it will probably last 20k miles before you have issues. The issues mean a new turbo. A BOV (it doesnt matter if it is a "quality" BOV or not, that has no bearing on this situation here), will destroy the uppipe cat. Not to mention, the whole point of my posts have been that this is not a good first mod for the car. Also, it is more dangerous than a turboback and reflash, because with a turboback and reflash you are NOT running extremely rich, and throwing fuel through the cat. Thankyoucomeagain
I will agree that the BOV should definitely not be the first mod, however, on my 02 WRX, a BOV was my first mod, and actually the only performance mod or better yet, Lack of performance mod done to that car. At the time I had my 02, there were very few on the road. In the city I lived, there was 1 other WRX. At that time, I was experiencing several issues with the Brand New Car. Issue #1 was a rough idle. When at a stop, my car would shake violently. I want to emphasize that it was violent. Issue #2 was with lift throttle. When I would lift off the throttle, the RPM would continue to climb anywhere between 500 RPM to about 750 RPM. At the time I was experiencing these issues, I was looking around on the internet for things to do with my car, and I came across a very good website that unfortunately no longer exists. The website was rallyperformance.com. The reason I claim this to be a very good website was because of the detail they provided on their website about what to expect from X mod. Unlike other websites, when they discussed their Scoobysport exhaust, they did not end their description about the exhaust like others did and just talk about the sound. They mentioned the "legendary" sound but went into much detail about what to expect in the low RPM range, High RPM range, provided dyno plots to show power band, etc... More detail than I could find on any other site, and still to this day more detail. On their engine modification page, they mentioned that an Intake provides no benefit, as is common knowledge in the WRX world today. However, in their description of their Forge BOV, they mentioned specifically the two issues that I was experiencing. They stated that they have noticed with the Forge BOV that both of these issues virtually disappeared. Occasionally the RPM may climb 100 RPM or so on lift, and the car may still shake at idle, though not violently by any means. The issues I was experiencing were starting to get on my nerves, so I decided to purchase the Forge BOV and install on my completely stock car. I planned to upgrade the Uppipe and rest of the exhaust in a few months after saving up the $1300 or so for the full catless system. As soon as I installed the BOV, just as the website stated, both issues were fixed. I never had any other issues with that car, for the short period of time I was able to keep it until it was totaled in an accident that was my fault and stupid, but I won't get into that here. Point of the story is, contrary to popular opinion, a BOV may be a valuable addition. You will not gain performance. Your car will not be faster 0-60, 1/4 mile, or anything really performance related, but it may fix small bugs like what I was experiencing. However, I never replaced the Stock BPV with another Stock BPV to see if it was a defective unit, which very well may have been the case. I also did not have the car long enough to know if having a BOV with stock uppipe would cause an issue as wrxin8or states in his most recent post, which I agree with 90%. I have seen a real life benefit from a BOV, so I also agree with callitarex that it is not the Evil device everyone makes it out to be. I have now had another Forge BOV on my 05 WRX, pretty much since month 1 of having the car, however I have also had my Scoobysport Catless exhaust for about the same time. I have never had an issue that can be tied to the use of the BOV, and it has been on the car now for about 3 years, and 50k miles. I do not intend to remove it from my car at any point, even though every time SS touches my car he asks when I am going to take it off.
welcome... stickers, meet somebody from the forum (likely a moderator) or go to a meet. here's your car in a nutshell... Swaybars (particularly the front) are a better investment than BOV. get them. TBE - get that too Uppipe - the stocker sucks. upgrade. Tune - get shortly after the above (or get AP now and use "off the shelf maps" until you have the cash for a protune-which is worth the money x10) cai - don't bother, just get a K&N drop in for now. when you go over 300whp worry about cai and do NOT run it without a tune. wheels - get 'em, 17x8 or 18x8, then put good rubber on them. steering rack bushings - get em also, will improve the steering feel and clean up the early wrx slop. whiteline makes them (and they cost less than BOV) shortshifter and bushings - kartboy is good and is also about the same as BOV... the stock shifter setup sucks. compression test and leakdown test - might as well if you bought it used. do these BEFORE tuning or buying anything else... you might need the money for unforseen gremlins. tranny - if it's stock 2002, keep some "rainy day" cash on hand because once you make decent power things will wear out (read: shaved gears). driving school - the best "speed" and control mod your money will ever buy.... www.siegelracing.com if you do this before any of the above (well, not the leakdown/compression) you will KNOW what you need to do to your car. and get to talk to some people who push these cars harder than most of the people on this board a couple of guidelines: do NOT hard launch your car (read: shaved gears) do NOT think awd will save you from your own limitations stuff WILL break you MIGHT cry DO have a nice day
ok well i just bought the invidia n1 3" from AirMax95, and i was looking for some people to help me hook it up. I fail when it comes to doing this kinda stuff myself. I live in marietta near wheeler high school but can travel a little bit. Ill pay you if need be . Thanks a ton
i have a garage, and 2 big ass tool chests. Let me know what you need, i'd prefer we do it at my friends house located near sprayberry. he has lifts etc.
Well, i'm trying to get it installed tomorrow, i was told i need gaskets but, not sure how big or where to get them. If i go to a store and say i need gaskets, they'll end up charging me for oil gaskets or something lol.
what you can do is take in the parts that you need the gasket for to autozone or advanced or where ever and they can match them up. Subaru of Kennesaw might have them as well.
^^^what he said! I would help, but I pm'd you why I cant. Seeing that you have a lift, it SHOULD take you 20 minutes, lol.
well its not quite a lift, its like, a roll your back wheels on 2 ramps and get 2 feet off the air then lay on thingy with wheels and slide under.
advanced auto parts had each of those for 4.99 and SOK wanted me to order them each for 15. interesting difference.
