HKS BOV Installation

The group that purchased the HKS BOV's are going to be receiving them within the next two days or so. I will be receiving mine on friday so i want to be ready. What will i/we need to install this? Where do we get hose to go from the turbo to the ic? What else am i missing here?

gezz blow off valve isnt hard to install. i dont speak japanese and it was about as easy as using a microwave.

weld flange onto pipe. put in the o ring in the flange, put the bov in there, then put on the clamp, and then hook up a boost/vacuum line to it. put on in between the ic/turbo and clamp it down. and there.

i guess you could also attach it to the manifold...

the bov itself (not vac) needs to be between the throttle body blades and the turbo to work properly.

Its an easy install, the hardest stuff isnt complexity, its just difficulties. maybe 20 minutes to install once you have the flange welded to a pipe.

You will need to have a metal turbo to IC pipe to weld the flange that the BOV mounts to. I bought the stainless steel one that Bob Galla sells for $50. You can reach him at rjgalla@worldnet.att.net Responses from him can be slow so, be patient.

I'm in the process of doing mine.
Here is the start of it with a couple of pic's.

You'll need to cut a 1.25" hole for the flange. I used a 1.25 hole saw once I found & marked the location that would give me enough clearance for the BOV.

Here is the flange resting on top of the IC pipe.

I'm going to braze my flange on tonight and will take some more pic's tomorrow, hopefully.

By the way, I could make some stainless IC pipes (un-polished, I don't have the time) if anyone is interested.
I don't know if Bob Galla is still making them, so I thought I'd offer. LMK

Hey Rick, are you mounting your BOV on the bottom of you turbo to IC pipe? I would worry about the radiant heat of the turbo baking the rubber o-ring that goes in between the flange and BOV causing it to leak boost...

It also won't fit (will hit exhaust housing). Even if it did, it would make it even harder to get IC bolts out if needed.

I can't believe there are this many posts on the install. :wink:

I don't have much of a choice due to the turbo & IC configuration I'm using.

The turbo to IC piping is a little convoluted, but it should work OK. (I'll have pic's soon)
I guess if I need to, I can add a heat shield around it. I'm already planning on cover the IC piping with ThermoTec stuff, so this should help. I'll just have to wait and see when I get it running.

Ah yes JEDI...you are wise. Yes....
If it were a stock truck. :wink:

Re: HKS BOV Installation

I just installed one on mine today. How do the vac lines hook up to it? I have a T in between the vac port from turbo & factory boost controller then to the BOV. What is the adjustment on the BOV? Turning the screw inward= less boost?

Re: HKS BOV Installation

Wow, old post.

The vacuum source needs to come from vacuum in the intake manifold, ie. between the throttle body and the pistons. I don't think It will work correctly between the turbo and the throttle body, in fact I just read my post above and it looks like I may have been a little vague in my description. Hook it up to the vacuum source at the front of the manifold under the throttle body, the rear of the intake manifold, or where it feeds the brake booster.

The spring on the back determines how easily it will open by increasing or decreasing the spring pressure keeping it closed.

Re: HKS BOV Installation

Its VERY straight forward guys.... the vacuum hose connects to the vac. port on the back of the BOV valve body and goes over or under the Intake manifold to whichever port point you choose....for example..
