BOV how-to question

Mark- Well I think I am going to go with a Greddy Type RS BOV with the recirc. fitting. I know the sound really isnt going to be as loud as I would like but really dont want to chance anything just yet.

I really would like to lean out the car a little bit. So please keep us posted to your findings.
 
I'm going with the CPE kit "The RPM Store" sells for the mazdaspeed 6 same motor and the flange is built to fit. Also it comes with the HKS Super Sequential BOV which can be adjusted from 100% recirculate to 100% vent to atmosphere. Seems like the best choice for anyone IMO. 289 might be pricey but it beats buying another one down the road if you would want to switch to VTA.

Really I didnt know that the HKS Super can be adjusted. I might have to look into that. Even though it is for the 6 it should work for the 3 right?

Disregard that, I talked to them today about it, apparently the flange for the 6 is a little different then for the 3 but the one for the 3 should be out they said in a couple weeks. I can't wait. Too bad though I wanted to get it on before I drove up to Philly for Christmas.

Well i called up a performance shop here in town. I have an appointment with them on Monday to talk about some potential HP increase. I would like a boost gauge, BOV, ECU upgrade of some sort, Wastegate ?. So we will see what they recommend for this car. I really do not want my brand new car to be test pig cause i need this thing to run everyday and not void my warranty. I will post my findings out on Monday night.


I'm sure they will be able to help you get a boost gauge/install it for yas, any you might even get them to help you with the BOV situation, most likely though they will just give options as to what you can pursue, as it's such a new car and they might not know jack about it.

ECU, what are you looking to get out of the ECU, or do you just want to adjust air/fuel, as an ECU mod will cost you a bundle especially this early on in the car's run, you might be better off with going with the DTEC-FC from Turbo XS, although I've never used the product myself, TurboXS has a way of taking care of business. If you are thinking along the lines of a chip for it, I'm pretty sure nothing is available just yet, however they are mostly just static versions of a fuel controller, making the car more efficient and tuned towards modding, which is the point of the DTEC-FC, but it's customizable.

Lastly as far as wastegate, your turbo, I believe, is equipped with an internal wastegate, and if you want to get an external one that you can properly adjust boost with, you will need to replace the turbo entirely, which in most cases involves replacing of the manifold and intake piping as well. Your best bet is to just go with a manual boost controller, which is more or less a controller boost leak to the wastegate, lying to the wastegate as to how much boost the turbo is putting out, making to turbo put out more, ie, more boost, or less, if that's your bag. I know TurboXS can easily set you up with a MBC for sure.

The wastegate on the MS3 is internal.

LOL. That reminds of the scene from Spaceballs where Dark Helmet says "I am your father's brother's uncle's former college roommate." or something like that.

My name is Mark and I am one of the two owners of TurboXS. The other owner lives in Australia. My only niece is about 7 years right now and last I checked she was no one's mother in law so you might have the wrong company, but thanks for the compliment!

In any case, as Jermaine said, the BOV adapter kit for the MS3 and MS6 is ready to go! More cool stuff is on the way. We will posting more info next week after the Thanksgiving holiday.

And to actually add something useful to this discussion, a vent to atmosphere BOV like our RFL will cause the car to run slightly rich for a brief second after the valve vents to atmosphere for the exact reasons Equinox posted. You will even get a little backfire now and again with a vent to atmo BOV installed on the MS3. Of course, you also get a cool "Ka-Chhhhhh" when you shift. Ah, life if full of tradeoffs...

BTW, we are loving the MS3. I haven't driven the EVO, WRX, or STi home since we got the MS3! I look forward to making a great car even better.

Off thread topic, but Where can we find your products? I went on turboxs.com and I couldnt find anything......

The mushroom looking item I believe is the acutator for the internal wastegate. If you could take the same picture but zoom out a bit to get a better idea of the layout that would help.

Look at post #4.

its called an internal wastegate cuz that mushroom thing with the rod going down the middle goes to the turbo. inside of the turbo exhaust side there is a flapper that is sealed shut until you hit the boost application limit and opens up the flapper to stop it from overboosting. An external wg is like what you find on the aftermarket deals for the n/a apps. it does not what so ever have a rod coming out of the middle for the external wg. also it looks like a mushroom that sits directly on the exhaust mani.

Hi!
I would like infos on how to connect engine hoses on my old HKS BOV.
Seems to be a very stupid question, I know, but I need to learn! :)
p.s: I have the flange that fit my engine (not pictured)

Here is my BOV (ignore the T pipe):
hks1.jpg


and my engine bay:
HKS2.jpg


question 1: Is that possible that my BOV is only VTA? cause I can't connect my hose #1 on that valve...

question 2: If my BOV is a VTA, can I use it on my car?? If I can, what do I do with hose #1?

Any help is appreciated!! I'm very new in the turbo's world....
(ugh)
THANKS!

Don't understand why the flange would be different from the ms6 to the ms3 they are both the same exact engine. I have the HKS SS on my ms3 and my friend the same flange and BOV on his ms6. Don't know where your getting your info from.

I can also say it would be better to recirc. As mentioned we already burn to rich from the factory. No need to burn any richer. With that said, my HKS is very loud. It is awesome. It is so loud sometimes i think i might have come loose....lmao.
 
Awesome you guys at TurboXS are making things for the MS3 and MS6. I am in Maryland, not that far from you. I think a friend of mine John knows you guys well. He is the owner of Speedesign. I havent seen him in awhile though. You gyus should look into making parts for the Mazdaspeed Protege too ;)....ehhh just wishful thinking, haha
 
Damn!
I think this was my first thread here...(old one!!)
everything is fixed as I bought a new HKS. This old one (pictured) was not designed to be in recirc.
everything works well now! (first)
 
argh... what do i do about a turboxs BOV to a MSP without having to weld and being able to return it to stock later on?
 
this may sound like a dumb Q, but i know nothing about turbo's and BOV's... I wanna buy one for my MS6, does any BOV work, or does it have to be a specific one for my car? and is ita long install?

thanks
 
NO intall is very easy and any BOV will do as lond as you have the correct flange to hook up the BOV to the intercooler. I have an HKS at the moment is pretty decent and love it. I can go vent to atmosphere or recirc. For these specific engines we must recirculate due to the ECU calibrating for the extra air coming back into the engine.

thanks, one more thing does it add any HP? and would i have to costum make the flange or can i buy it too?
 
Negative, flanges are available. Just depends on which BOV you decided to get. But I am sure which ever you get there will be a flange available.

what flange should i get for my ms6 if i get the same bov as u?

and when i install it is it a basic bolt on, like replace the existing one?

thanks again
 
BOV will not give you any horse power, and some people have experienced problems with them and actually lost power.
