Replacing BOV

What do most of you guys do when replacing the BOV? Do you make a blockoff plate for the stock? Or do you just run the stock one plus an aftermarket?

I know when I got my turbo smart BOV it came with a "cork" for the accordian hose side. I don't know of many people running two bov's, but if you had hardpipes w/ bov on them then it wouldn't be impossible.

I run both stock (well, bosch) and an aftermarket venting to atmosphere.

Runing either toyota or lexus AFM setups (AKA draw-thru) without recirculating air causes pig rich conditions when blowing off.

Has anyone realized that this is a JZ thread? There is no AFM, there is no place in the intake pipe to cork it.
Its a flanged Stock BOV on the piping to the turbos.

I would take it off and fab a block plate. Shouldnt be hard.
I guess you could run both though. I have done that before also.

im running an aftermarket one right now with the stock because i havent gotten a block off plate for it yet. it seems that the aftermarket one is doing alot less work than the stock (i still hear it predominantly). so i guess im just gonna take it back off until i get a block off plate, or just plug up the stock one :dunno:

Thanks! I was getting a little nervous with all the AFM comments. lol

The only thing I'm worried about is there's only 1 bolt that holds the BOV on. And I'm afraid a blockoff plate is going to leak. We were thinking about welding it shut, but then I thought maybe just run both, so I wouldn't have to mess with it. Then I started to think if the stock BOV can even hold that much boost. (17 psi) Anyways, I do appreciate the help.

Yea I looked at it a little while my twins were off.
I just decided to wait to put my HKS and hard pipes and IC and shit on when i did my single install

If you make the plate right it shouldnt leak, but I would think just a flat piece of metal would though.
Maybe seal it with silicone or something similar.
Welding a plate onto it seems a better option though to garuntee it wont leak.

All right, that's probably what I'm going to do then. I don't know how long I'm going to keep the stock twins on for. Probably until they let loose. Thanks for the reply.

not realy a good pic,but it is mounted in the stock location(turbo x)as a recirculator.i also have a blitz hardpipe one for the jza70,but no pics of it.i don't really like the stock location because the air probably will still stall the front turbo with the bov mounted on the rear inytake pipe
