I did a search and was surpised not to find anything. Has anybody tried a forge or similiar recirculating diverter valve on our stock intakes? If not any thoughts on this would be helpful...

Your search wasn't very good.  Forge made a special DV for our cars that fits in the place of the stock unit.  The problem is that the stock TBP is likely to break eventually since it's rubber.  So you would need to replace it.  BEGi makes a metal one to work with a stock style valve.  The FM unit is arranged differently and you would need to plumb things differently to use a stock style valve.  To get the Forge unit you have to call Forge (407 447 5363) and ask for Mike and order it through them since they don't seem to be able to list it on their website for some reason.

I have a Forge valve but I have an AEM intake. I'm happy with the valve. The car immediately achieved higher boost and was able to maintain it. Being that the stock valve is known to leak, I would assume it is beneficial even with the factory intake.

I know ALOT of you helped me figure out what to do with my car, and a few helped with my girl friends, I am going to be getting her a magnaflow exhaust and fm down pipe for x-mas, she wants more power without any of the bs that comes with it. thought this would be a good way to achieve that, (plus lets me try it before I get it for my car) and I was thinking while i was at it I would go ahead and pickup a begi tb pipe in one inch and fit it with the forge valve they offer.... and I guess my question is, would this work? And would it make any diff at all, sound, or otherwise?

I have the FM downpipe and Magnaflow exhaust. On the highway, at cruising speeds, you know it's there but I don't find the sound intrusive. My girlfriend doesn't mind it at all. At WOT, the exhaust is loud, to me anyway, but in a nice way. Like a little V8. Very powerful sounding, unlike the fart cans on many modded Hondas. My girlfriend actually likes when I go WOT, but that might just be to make me happy.  Smiley I would definitely get the Begi TBI and Forge valve. That is the setup I have and I love it. I also have the AEM intake. While the intake sound is noticeable, which I love, at WOT the exhaust dominates. At partial throttle, I hear more intake. It's a motley crew of sounds I love tremendously. I installed my parts in stages; intake first, then exhaust and downpipe a while later. The intake by itself made a noticeable bump in power, but combined with the full exhaust, the difference was tremendous. I'm sure it would be the same if the exhaust was done first and then the intake later. In my opinion, they are meant to be done together as they seem to compliment each other (intake and exhaust). I hope this helps.

I have a black Forge BPV with all its springs and inserts I could let go. I recently changed the o-ring and relubed the unit. It has about 15k miles on it, works like new.

I doubt it. I thought it sounded the same when I swapped mine. The stock intake should block any sound from the valve.

The forge with stock intake works great.  No sound difference.  I have run my forge with both the stock intake and AEM.  Great valve overall....

BEGi also sells the Forge Valves for the MSM. We have both the 3/4" and 1".

Received.

Now that I think on it clearly it's an FM style one with the BOV on the left so you can use large valves like the GFB. Since I was using the GFB I got with my FM intake kit.

I picked up a second hand Forge valve here.  It is installed in the passenger side of the OEM throttle elbow, oulet pointed down.  My temp sensor is diff from the MSM, but I believe you could easily adapt the MSM sensor to fit the smaller BOV nipple on the OEM elbow, then deal with an aftermarket elbow whenever you need/want it.
