I recently replaced my FM valve with one of these:

And I'm actually very happy with it! I took it apart and removed one of the springs to loosen it up. Now it leaks like a sieve at idle, which is fine since I'm running sans-AFM. (others could recirc.) I just lathed an adaptor to stick a filter on the exhaust so it can suck in all the air it wants. A lot of 'em include the recirc pipe at no cost.
No problems at all so far.

I have a brand new Turbosmart V-port that is too stiff for my TT's but should be good for anything else out there. PM me if you are interested.
I'm running a remachined FM part now with just about no preload.

If you are venting then a Tial is the only way to go. Let me know if I can help you out at all.
The HKS is so ******* annoying. I think every 18 year old kid in my area has one on their STI.

I VTA'd my Bosch with a Lowes check valve for about 3 months. With the .48/.49 DSM T25, even at high boost, there wasn't enough air to make it flutter or sound cool. Just a really loud "pssstttt" like when you disconnect an air hose from a compressor. When I "upgraded" to the .80/.64 Nissan T25, it fluttered like crazy even at moderate boost, sounded good, and wasn't too loud. But after a month or so, the noise got old and I got tired of every dork in a big-winged Sunfire giving me "the eye". So I recirced and found new joy in life. All of my driveability problems went away, no more bucking... and my mileage went up from about 18 to 22-23. My **** feels a little smaller though.

I've used Greddy Type S, knock off Type S, RFL, knock-off RFL and a DSM.
DSM was by far the best mechanically. Held boost great, sounds good dumped to atmosphere and is super responsive, plus it was the cheapest of all.
Tial and **** is good quality too but you cant beat the DSM as far as bang for your buck.

I can't handle the "flutter" noise. I can handle the poosh noise...I think.

I can give you a deal on any of our valves.

What kind of deals can you get? I really like the looks of this valve.

Since you're here Pat.......do you have a spring recommendation for me? The Vr6 pulls about 20" of vacuum at idle. I will be running 10-22 psi. I have a green spring and a red spring sitting here I can choose from.
