Apexi Avcr Solenoid
just bought avcr, the car that its off was recently in accident so the one of the solenoid is missing.so now i am wondering where can i get solenoid from

You can probably order one from A'PEXi, but I understand your aversion to pursuing that path since it can be like pulling teeth to get parts for this kind of product. I would at least call A'PEXi before going too far down another path. Contacting a shop that sells A'PEXi parts might be worth a try as well.
Based on it's appearance, I believe the solenoid is a standard industrial pneumatic solenoid valve. You might be able to get it from a pneumatic/industrial supply shop. I just looked at mine (installed in car, didn't get to inspect it that carefully) and I didn't see any part numbers or manufacturer identification (besides the A'PEXi sticker), unfortunately.
You want a 3-way, 2-position, single 12v solenoid-operated valve. I think it is 12v anyway -- I suppose the AVC-R could be feeding it 6v or something, but that seems unlikely. You could test it to be sure. I poked around http://mcmaster.com and didn't see anything that looked exactly like the A'PEXi valve. However, something like part #6124K511 might work. Or maybe #61975K55 with the #61975K8 base -- this combo is my best guess at what might work from mcmaster.com. However, it could also be a disaster if it doesn't flow enough or has some other major difference. I noticed that some of the valves have a minimum value of like 29psi, which might mean they don't work at lower pressures. Some are not vacuum rated, either -- the pressure port will see vacuum when you are off boost, but I can't think of why a valve that isn't vacuum rated would lead to a problem. At worst, it could cause the valve to stick which would be very bad, or it might just be a vacuum leak, though that seems unlikely. There is some description on page 948 that says "respond much faster to electrical signals than other solenoid valves", which also gives me some concern about valves that might be slow to respond. Operating temps might be an issue as well. Page 942 describes the terms and how the valves work (simple internal flow diagrams). Valves of this description appear to be about $50 or $60.
I would tread carefully when trying a different valve, since minor differences could cause the boost control to fail and blow your engine. It would be a good idea to have a pop-off valve if you decide to try a different valve. If you are uncomfortable researching this and making a purchase decision, I suggest skipping the option of finding a different valve and just focusing on how to get a new valve from A'PEXi.
