Can I change the stock BOV to VTA
Why is everyone so quick to jump in and say "It'll make the car run like crap" and "It's a terrible idea"? Have you tried it? I have, and the car runs exactly like it did before, absolutely nothing different about it.
Yes, the 4B11T has a MAF sensor to meter the amount of air coming in, but it also has a MAP sensor in the intake manifold to measure the pressure. A VTA BOV doesn't have the same effect as it would on a strictly MAF metered engine.

Like somebody else stated, just buy and intake. I have an ARC intake and it's pretty damn loud, I can't imagine how much louder it would be with an cone filter intake like AMS. This way you're actually making a tad bit of power and still have the sound.
The AMS is loud. Loud enough that I can hear it with the windows up and the stereo at a reasonable volume. I can't imagine any situation where someone would want it louder than it is with a cone filter.
I'm sorry guys, I didn't expect my topic will turn the thread to a battlefield between JordanS4 and shyong.
I metioned,it's just for fun,I'm still a nooby of tunning cars,so still learning.I know some basic theory of how BOV works, but have no experience of what it's gonna do to my car after I mod it.

If you switch to full VTA, the air that is discharged from the BOV has already been read by the car's MAF sensor and the ECU still thinks that air is going into the engine. Since it isn't, you will temporarily run rich in between shifts when that air is discharged and could cause stalling. That's the only problem I think that could happen. There's no point in converting the VTA with a MAF monitored car. You could do it later if you change to a MAP sensor for fuel management.
