HKS BOV
 

well i just got my mazdaspeed 3 last week and so far ive been loving it. i just joined this forum and have been researching alot over this past week.

so i picked up the car last week and the only mods done to it were a FMIC and a HKS BOV. After doing some reading on this site i read that having an atmospheric vent BOV can mess with your fuel trims. so im just wondering if its worth it to spend the money to get a BPV or if the effects of keeping it on are minimal and i shouldnt be worried about it. Because if i dont have too i could spend that couple hundred bucks towards a new downpipe/catback exhaust.

I do plan on doing some more upgrades in the near future such as downpipe, SRI, catback exhaust, turbo inlet pipe, and a cobb accessport and getting a tune. so im just wondering if ditching the HKS BOV would be beneficial in a significant way.

first things first, just get the bypass valve kit for the HKS, second, the ONLY thing you need to be buying next is new internals for your fuel pump, dont make another upgrade to your car without doing that or you will lose fuel pressure and bad things will happen, really for doing a week of research you didnt read the "new owner" sticky threads?
edgeautosport.com will hook you up, now GO!

sorry I thought u said '' have been researching alot over this past week'' ? So the only thing you have at the moment is a front mount and a bov and u plan on going dp. Id read up on those HPFP if I were you. There is a thread on here that clearly states the steps you should be taking if you dont want to kiss your engine goodbye. But on the question of the BOV ,running it VTA will make the car run like shit, throw cels and backfires. Sorry if what im saying is sounding harsh but you should read this to start off. http://www.mazdaspeedforums.org/foru...daspeed-92852/

okay thanks.

i didnt know the fuel pump internals were completely necessary right away. i did plan on doing it but i forgot to put it in the list of mods i planned on doing. guess ill be buying that next.

and also didnt know they made a bypass kit for the hks. thanks

RMM -> Internals -> AP -> Intake w/TIH -> DP/RP -> BPV (If you run a tune higher than 18PSI) -> Short Shift Plate -> Shifter Bushings -> Oil Catch Can

Call Edgeautosport.com and talk to Erick or JP

ermmm so a FMIC and a BOV over a AP first? :O


HPFP and AP should be next mods. Just buy the recir kit for the HKS BOV you already spent the money on it so no point in buying another unless you don't like it.


The real question is what is the future plans for the car. Not trying to be bash but first mods being a FMIC and a BOV just says look like meeeeee I'm boosted!!!

Reading comprehension fail. He said he bought the car with those mods on it. Give the kid a break.

This thread is full of fail advice.

Internals are heavily suggested prior to installing a downpipe. I would suggest a monitoring device before the FP and DP. You don't however NEED internals immediately as these fags suggest. Get an AP or the like and monitor that pressure.

Lol @ the tool above recommendong an SSP and bushings before a catch can..logicwut?

Meh, you could just pull your IM and clean your intake valves with every oil change.

Sounds like a blast....

And it isn't about needing an OCC, I never said that. Its about even having an SSP and OCC in the same list..

If I was to do it all over again I would do the following mod list:

Internals
FMIC
Mounts all around
AP
Exhaust like mine
Big Turbo with whale penis, top-mount mani, and correct downpipe.

After the recirc kit, get AP and custom tune. Monitor fuel pressure and if drops below 1600 when WOT, then get internals/hpfp. Add race pipe (cheap mod) then retune.

Nothing wrong with a little vta :)

no real problems with vta if you adjust your tune. running recirc is just easier...

Yeah I get some part throttle quirks running vta but nothing that cant be avoided :yup:

Same here, I'm actually running about 80/20 with a GFB BOV..best there is..

They make some really nice pieces

Oh man, @atvfreek actually turned me on to it....I had not heard of it until then.

Unfortunately, there is a little rice..way down inside me..I had tried the Forge V1, which got annoying in about a week...PING! I also had an HKS. But this GFB is just monstrous! Great sound, great built..great boost!

I'll likely get their MBC as well.

You can run the HKS as long as you get an AP and have it tuned for a BOV. Our cars are designed for recirculation and will run like ass in VTA unless you have one of the guys on the forums tune it for VTA. Anyway ... Grats on the car and your first mods but really read up on what to do first before you VTA your block!!! HPFP first and foremost!

wow. why would you rez a dead thread just to post something that is in stickies?

Didn't look at the date when i read it....

Do you have something against old threads? Do they haunt you and make you feel insignificant? Troubled childhood memories? What is it about old threads that get you tore up?!

they're dead for a reason. when someone revives one it usually means that person is one of two things. 1. a brownie who doesn't feel like doing some searching on a topic and posts in teh first thread they find about said topic or 2. someone who read the thread and thought they could add something useful even though the thread has been dead for a while, which usually means the OP found the answer they were looking for elsewhere and has all but forgotten about the original post. either way, it's just a stupid thing to do.



dead threads raped my dog also.

Then i apologize for your dogs loss of innocence... I think i would fall under the category of ... read it and didn't look at the date.... I didn't see that in your list. You must have failed to put it in there.

hmmm... im in the same situation
 

I getting a 2009 MS3 and it hesitates sometimes when it spools up quick it has a HKS BOV but i dont think its recirculating how do i check ?, and im getting the cel p2177, what should i do get an AP first or fuel pump internals or the recirculate kit, also have a cold air intake

@sbchedder;
I suggest if you can afford it AP and the recirc kit. With the AP you can log and see where the engine stands. Internals after that but you will need a device to monitor fuel pressure.
