I think you need to answer that question yourself. 
You could even install one on a 7MGE if you really wanted to.

as 7m has an AFM not MAP sensor. the consequences are that it will go pssshhhhtt and blow a cloud of smoke when you back off and your rear bar will be permanently black 
AND 'NO YOU ARE NOT ALLOWED!'

3 ways
1. use a plumb back BOV
2. dont replace your standard BOV
3. plug up your 'zorst

I've found that a good way to avoid 'Black Rear Bar' syndrome, is to stuff a nice, ripe bunch o' bananas in your tailpipe.
Now, here's the cool bit - it acts as a sort of silencer too, so no more attention from da 5-0, my man....
As it is an AFM set up, just don't replace it coz you WILL get the black cloud, black bar and it will run fucked sometimes, like after you change gears and may idle like a pos on occasion.
In any case, as I stated before, you're not allowed anyway, so just forget it and go to your room.
NO TV FOR A MONTH!

or u can get an safc type 2 which will compensate for the air released by the bov into the atmo
u can run a bov to atmo on afm equipped cars , but it will run rich in gear changes and when u back off the throttle
also car might stall when braking hard and might idle rough
if u still wanna do the bov thing ,get an apexi safc type 2 and fit it on ur car its a piggyback ecu for the fuel and u can adjust the rate of fuel and do heaps of other stuff it costs about 500 ish new plus tuning

no joking around. you have obviously had this problem. thats cool. why wouldnt you replace the AFM so the correct amount of air will flow through and be mixed with the correct fuel amount?
why are you not allowed? not making sence.
its obviously blowing smoke for a reason? what reason?

No I ahyvent had the prolem yet have an 1g-gte soarer , but will be doin the asame soon I got a blitz bov to go on
An afm measure the amount of air entering ur cars engine and send a signal to the ecu to say how much fuel it need s for the amount of air that has passed through , but with ur bov it vents the air that has been measured by the afm , so the ecu alredy knows how much fuel to squirt through the injectors
But if u vent a little bit of the air throught the bov , then the ecu doesn’t know that the air has been vented and will supply the fuel for the air still
the fuel tha s suplied will now have no air to burn with and will be burned by itself resulting in the black smoke that comes out the exhaust , the black smoke is actually the extra fuel that was supposed to be mixed with the air that was vented out by the bov
so there no way in hell a change in afm is going to help if the bov still vens to the atmosphere , thats why its recirculated back into the intake piping so the correct amount of fuel is stil there for the air
hope that helps

1. Buy the BOV
2. Buy the SAFC
3. Get the BOV fitted
4. Get the SAFC set up
Now ppl will hear you coming from miles away with a fooly sick PPPPSSSSHHHHHHHHTTTTTTFFOOOOOOOOWWWWWWAHHHHHH noise.
Simple.
And no, I'm not joking this time.
P.S. Please don't put bananas in your tailpipe..... Unless that's what you're into

answer to all ur questions is just one little gadget
APEXI SAFC TYPE 2
it will adjut amount of fuel so u dun run rich
can run higher boost
will compensate for the bov venting to atmo by tricking the ecu of the car ( dun ask me how that works , but i know it does )
remember the type 2 only does this type 1 cant do the tricking bit
some one correct me if im wrong
u dun need an ecu upgrade
if u want the whissh noise u need the bov enting to atmo for that to happen u need the safc or ur car will run very rich and stall and idle like crap
but some people have actualy fitted an atmo venting bov andhad no probs at al
so my best bet is fit the bov see how the car runs
if it idles and runs rich too badly ten u need the safc
or u can just plumb it back and have no noise and no hassels
plum back will give u a loud enuf noise to hear in the car , if u fit a pod filter

On second thought, I just realised something. On my R32 I had a BOV venting to atmosphere and it didn't run that bad. Just almost stalled when snapping the throttle closed after having it under a fair bit of load e.g. driving up a steep driveway.
I reckon you should just get the BOV fitted and see how it runs first before shelling out $500 or so big ones for the SAFC.

yeah my old nissan exa had an afm and i had a bov venting to atmo o it , it still worked well , but car was running rich it happens with the afm equipped cars
try it out first buy the bo and fit it and see wha happens if its not running like norml , ad u dun like it then get the safc
but id recommend the safc as it help u get more out of the car
like u can run more boost and still use less fuel than u were using when the car was stock
its a good upgrade in the long run
u can get it from the for sale threads just have a look around , shps like autobarn sell them around 500-600 dollars
or u can contact
supraman
he has got some for sale and can do them cheap
cheers

The best solution for you is to replace your 7MGTE with a 7MGE and fit the blow off valve, that way you will have no AFM/mixture problems. The only catch to doing this is you will have to have your windows down at all times so YOU can make the full sik PPPPSSSSSHHHHH noise so everyone can here you coming, or you could just keep honking your horn, that way people will hear you coming too.

on a totally serious note (for once)
if you REALLY want the full sik noise, then you can get a kit which uses a speaker in the engine bay to simulate the fooly sik BOV noise on gear changes.. or you could have a bottle of compressed air in the boot  .. or you could rig up an air-con compressor to fill a pressure vesel and vent that
venting to atmosphere on an AFM car is just stupid.
if you need a bigger one, get a second plumb back one
if you need the noise, get the speaker kit
if you MUST have the noise AND you don't want the car to do bad things, get aftermarket ECU and MAP sensor.
or just vent to atmosphere, have the car run like shit on gear changes and just tell everyone it's because you have DA FULLEST SICKEST BLOW OFF VALVE MAAAAAAAAAATE....
sigh...

heres what to do
(damn i'm bored)
put a spark plug in your 9 inch exhaust tip and hook it up so it sparks like buggery when the BOV opens, id suggest using a microphone triggered switch with the microphone listening to the bov,
this way, on each gearchange you will get two noises,
PSHHHHHHHHH
and BANG and flames and shit out the back!
double cool!

AND IF IT F*@KS UP UUL GET
PSHHHTTTTTTT
BANGGG
KAAAABOOOOMMMMMMMMMMMMMMM
dude if u got the money to spend go aftermarket ecu
will get rid of the afm and all
if u only got little money get the safc and tune it
no money --- run the bov and suffer ( might get away probably )

i guess what it comes down to is
"FOOLY SIK COSTS MONEY" (isn't that the point? cos only the wealthy fooly sik duudes can be foolest sikest maate?)
if he only wants the fully sik sound, then why not simulate it with a speaker??
whats wrong with plumb back BOV's??

You don't need an ecu upgrade, you need an engine upgrade. 1jz and 2jz is MAP sensored, so you can vent the BOV to atmosphere with no worries.
Mine used to go Pssssht all the time ..... not that I gave a shit but it really pissed off v8 drivers when I went past It was wank value, but who cares?

What do you have anyway, Supra or Soarer? You might have to get used to pushing a 7mgte over the line anyway.
Wheres Allan to defend the 7MGTE honour?
Meh what am i talking about my 1J aint running at the moment anyway

Thats coz the soarer autobox retards the ignition on gearshifts to reduce wear on the auto, not because of the BOV venting.
My manual 1jz never used to blow black smoke on gearchange. And it had the Psssht noise in spades.
Use a bloody recirculated BOV - at least it will actually work with your engine setup. Who cares if it doesn't go psssht. After 2 weeks you're sick of it anyway.

There should be a bounty on the head of the guy who came up with the term BOV. How can a vacuum operated valve create such fascination...and stupidity.

Oh, Christ what is happening to Rex's tech section
Now listen up...
Why the hell would changing the AFM make a difference to the Atmospheric venting black smoke problem?
It wont make a bloody difference because once air is metered through it, the ECU assumes the engine is going to use it and a corresponding amount of fuel is injected.
If you 'blow off' a chunk of that air through your polished irritating little wank device, it makes square bugger all difference to fuelling because the ECU still thinks the engine is about to use it, so for you boneheads that means the engine runs extremely rich for that second.
Rex cares not if you replace it with Gods own AFM, it wont make a bloody difference.
If you do 'have' to fit a big polished 'BOV' (christ Rex hates that term) plum it back to (a)Do it properly, (b)Fix the smoke problem and (c)So Rex doesn't hear it and put you on His short list.
Nor does Rex think an S-AFC will make a difference...
