I guess ill give it a try..what would you guys reccomend for a atmospheric bov or a recirculating bov? because I have a hks type 4 but I don't what would be better. People told me that if I make it atmospheric I got to tune up my sti because its not going to be getting all the air it normaly would ?

But I mean what better atmospheric oor recirculting?. But if I make it atmospheric do I have to tune up the car afterwards
Recirculating. Like the stock unit.

Recirculating. Atmospheric has potential to lead to problems because you will now be running rich in between shifts. You can't technically do anything to tune for this either.
So, stick to recirc.

Dam so for how long could I run atmospheric till it starts to leak so I could could order the recircutating kit
See The Big BOV thread.

Thanks..what size do I have to get the recirculating outlet 1" or 1.25"?..what if I use a fake hks bov would it mess up anything? Cause I bought my bov but idk if its a fake or the authentic one
Dude, you sound like me when I'm drunk/high.
Boost gauge question: If you are uncomfortable with electronics. By all means, pay someone else to do it.
Don't run the HKS(atmospheric) unit at all. EJ257 said to run the STOCK(recirculating) unit until it leaks, which isn't a problem for most people. Just buy a used stock unit and swap it.
I have no idea what size the stock BPV hose is, frankly I don't care since unless its the stock hose or a replica silicone it will be a MAJOR pain in the ass to route a straight hose. Either buy a stock BPV unit with the stock hose or a silicone replacement hose.
Defi boost gauge was easier to install vs. SPT boost gauge.
As stated, use fuse taps.

Hey guys, great info on this thread, this is my first post on this forum and I was wondering nif I could get some help.
I have bought a prosport boost gauge for my wrx my09, and I have no idea where the boost line is!?!?
I've located what seems to be the boost line, but its so short and hidden away that it looks like a massive jobe just trying to connect the T fitting of the boost gauge to it. Any ideas?
Thanks![]()
Wait, you mean there's actually useful info here and not just BS?!
Hahaha just kidding.
Usually for the 02-07's we'd splice into the smaller vacuum tube of the by-pass-valve and add a T fitting there.

Ahhh OK cool. I'm a bit slow in learning this stuff. The amount of research I did just to find out about a TBE was ridiculous.
Below I circle what I think is the BPV in red, the tubing to it is massive compared to what I was given for my boost gauge, is that the spot? I also put a red box around the area where I think the boost line is. I was originally thinking of joining the tube in that spot.
Sorry, I just like to know about this stuff before I cut a brake line or something haha.

The little tube where the red circle is where you want to splice in to.
Here's a writeup. You can see where the line was spliced and a T-fitting was added to.
And that tube in the yellow box looks like a breather tube for the heads. Someone correct me if I'm wrong.
