Turbo XS BOV install

[Bud92gsx]

I have an blue TURBO XS BOV. Now I need to know what I need for install in a 92 GSX, and how i go about doing that. Thanks guys!!!

Was taken is my bathroom, pics pretty much suck but you get the point.

well, since you can't recirculate that BOV, you're going to have a bunch of headaches using a MAF system with an external dump BOV. That's not to say it can't work or be used, but it can and will cause the car to at least stall quite often. As for installing it, you're just going to have to find a way to mount it's flange or whatever you got with it to the stock BOV location. Just look at it and figure out the best wayt o adapt it. Then you're going to have to plug off the BOV return line on your intake pipe.

You're probably going to get flamed for not running it in recirculation, but hell if you want to do that it's your car, I did mine when i first got it just to have that loud BOV sound 10 years ago, now i wish i had a recirc type to aid in performance between shifts, good luck!

So if i use it i can't recerculate it? and will make my car shoot flames huh! cool, but then the boostdrop between gears is going to suffer. Now can i just take it and tig it to my 1G and hopefully work great. Ill even go out an undo the stock BOV and post pics so you can give me some more understanding on the subject. Thank you for the reply!!

The BOV not being recirculated will just cause the ECu to not give enough fuel when it's open under vacuum because some of the air going in isn't getting meterd by the MAF sensor. Alternately i've also seen them over fuel because the turbo spinning (even at idle) was sucking air that was blowing out of the BOV while it was opening and not making it to the combustion chamber, but the ECU/MAF meter saw the air coming in so it added fuel for it, and the fuel is injected right at the port, so even though not all the air made it in, all of the fuel DID!

I didn't have too many issues with mine for the short time i ran a MAF meter and used a SAFC to control the fueling needs. I just tuned it the best i could to run on the open blow off valve. But now that i'm running in speed density, i don't HAVE to have it ricirculate, but it would be nice to have that air blow back through the turbo to keep the shaft speed a tad higher between shifts

See if you can find an adapter for it so if you wanted to go back to stock, you could in a matter of minutes. My car was venting when I first got it and I would stall almost every time I pushed the clutch pedal down. One time, I stalled at over 50 mph.

Here's the info I have for you now. Apparently my BOV is already crushed!!! Inever knew it cause I never took it out. That I just did.. The 1G BOV is freakin stiff, Or is it cause the BOV is crushed It's sooo freakin stiff?

 

[Bud92gsx]

Is it crushed?

 

[Bud92gsx]

Crap I forgot too take a pic from side. Ohh well I already reinstalled the BOV.

Yea, that's crushed for sure. I've been told a properly crushed one will hold 30+ psi, but i've never pushed one that far. Myself and most of my customers have already bought an aftermarket before pushing that much boost.

I did have a crushed 1g on my car when i did a pull at 26psi once, and although i couldn't tell if it leaked, it was one fun ride! I've barely ever driven my car above 24psi just because i would get too much wheel-spin with any more 19-20psi. I have done a few highway pulls at higher boost levels though and man, this turbo really comes alive over 24lbs, i thought 20 was fun, but the few pulls i've made through the years with 24+ were borderline of scary and fun, to have one wheel spinning and torque steering you from one lane to another at 100+ mph is a little spooky! I've only ever been to 28psi on the dyno with my car, it made a best of 468hp/429tq on those few pulls. I've yet to make numbers that good since either

Yeah I knew the 1G BOV will hold 30 psi. I wanted to know if crushing it is gonna make It alot stiffer than usual, cause the Turbo XS one I have is really not stiff at all. That would probly go off before i even reached 10psi. My buddy had a 97GST and thats where It came Off of. He was only running stock boost..
