Alright, I have stock TMIC. From what I've read the stock setup of the 7, there isn't a BOV but a Air bypass valve. Is this correct? If so, where is the air bypass valve located? UIM? I haven't read about BOVs in any FSM. If I'm completely wrong then I need to get a BOV. Anyone have pics of a aftermarket BOV on a TMIC setup? I just read that you have to put the BOV on the COLD side of the IC. But there is like 6" of piping on the cold side of the TMIC, so there really isn't anywhere to mount an aftermarket BOV because the stock piping is rubber. Somebody set me straight.

 

you need to buy either an adapter pipe which replaces the hotpipe right where it rises up from the turbo, or you can attache a rubber hose to the stock outlet location and attach it to the bov.
ill try to find a pic somehwere
nvm i cant find it. try searching for engine bay pics from 2nd gens.

 

Well, if I don't need a BOV, I'd rather not have one right now. I'm trying to stay stock as possible (trying to keep rice factor low). It's just with the piping I have, I don't see a place where a BOV would go, nor do I know how to connect the Air Bypass Valve up. Any pics of stock turbo setup that shows where vacuum lines are being ran?

 

They're basically different names for the same thing.

You won't, because Mazda calls it an air bypass valve. You can see it on FSM page 4B-5 plugged into the TID. The other side connects to the cast aluminium compressor outlet pipe.

If you want a noisy BOV, or you're running high boost, you need an aftermarket BOV. If not, the stock BOV (ABV) works fine.

There is no need to relocate it, the stock location works fine. If you're making FMIC piping, then you can worry about which side (supposedly) works best.

 

Sorry to disappoint you, but you need to keep something that does what the stock unit was designed to do.
It actually has a very useful purpose (search for "compressor surge").
Without it, you'll end up killing your turbo in a very short while.

Also, beleive or not but Mazda knows what they are doing when they put together your car. They also know turbos well (they've been around for a 100 years). If its on the car right now, its probably doing something good. Unlike air pumps .

 

Actually their first turbo with a BOV was in the FC...

 

I meant with Turbo's in general yo. Sorry for any misunderstanding .
