i have an hks bov from my sr20 swap.. its already on a pipe but where should i put it on the intercooler pipes.??
suggestions on where to put ssqv
- Thread starter jza240sx
- Start date
I'd buy a flange from titanmotorsports and have it welded between the turbo and intercooler piping. Thats were we put my buddys.
You should put it somewhere along the intercooler piping. If you want a loud open sound, somewhere close to the intercooler where it isn't as covered will be a good spot.

i hear its better to run it close to the intake manifold but what ever works lol after i install my ssqv..should i just unplug the vacuum lines from the stock bov and block it off with a screw or something or can i use that vacuum line to plug to the ssqv
Have you also considered that you no longer will be recirculating the purge and the potential issues that will bring?
Unless of course you a recirculating your HKS unit. If so, then carry on, nothing to see here, LOL.

yea i hear problems start coming up once you release the air into the atmosphere but that problem is solved by placing it near the TB. dont qoute me there im just saying what ive heard
out of curiousity..ive never heard a stock bov on a JZ. DOES ANYONE HAVE A SOUND CLIP OF WHAT IT SOUNDS LIKE WITH THE STOCK BLOW OFF VALVE???
I don't have a sound clip, but it sounded pretty nice on the RHD one I was driving around before I sold it. Function is the main purpose, the sound is a fringe benefit for some.

i really can care less about sound but i was just curious since i never hurd one with the stock blow off valve lol the recirculating blow off valve on my sr20 sounded nice as hell tho:biglaugh:

Closer to the TB allows more time for the air to respond to the opening of it because its the futhest from the turbo to help avoid surge, Also if it is higher and it malfunctions (stuck open) if its mounted lower it can possibly suck water at vacume points (hydro lock bad) also its exposed to more elements lower on the car especialy when missing lower dust covers.
As far as Recirc on a 1JZ thats BS you could drive your 200hp 1JZ-GTE with all the turbo air plumbing disconnected and it will still run fine.
However when driving a 1JZ-GTE you would expect to get at least 280hp so I would leave the plumbing connected.
So for bov either config could be used as far as recirc and it wouldnt matter so use the most efficient & one you see fit.
Although it has already been stated, I want to also say that it should be placed close to the TB.
As for the old set up, you can just have plates made and welded/bolted on the two spots. Thats what I did.

i seen people run both blow off valves at the same time. Is that any good?? i think that may be a good idea just to make sure the turbos dont surge
Mine is on the hotside of the intercooler.
It makes little* difference IMO where you put it. Venting hot pre-chilled air makes more sense to me than venting chilled air. The air stops at the TB very quickly so venting near the source of pressure (at the turbo) makes more sense than trying to keep forcing air through an intercooler before you force it through the BOV, overcoming a barrier (the intercooler) just to blow out of the pipe. Not exactly the ideal path.
Your throttle body will not break because you aren't running a BOV, the turbo could be a different story and should be the focus to relieve pressure there. People get really scared of surge when they pay $2000 for a turbo, others don't care. If it works for you the way you want it, great.
The hot side of the intercooler usually has more pressure than closer to the TB anyway, as all intercoolers have pressure drop meaning more PSI on the hotside than the cold side.
Those are the points of my argument for the BOV to be on the hot side of the intercooler because anyway you slice it there's always more pressure there, and it might even help with flutter.
