Tiny Update:
As many of you know I love ebay parts and am willing to try them out. Well I have been running the eBay HKS SSQV for a while now and it seemed to work well. The only issue I was having was part throttle boost. If I would get into boost a little and let off a bit "such as merging onto the highway" it would flutter and open and the car would not like it. It was not smooth at all and annoying to drive around. This made me sad as I LOVED the bird call noises it makes otherwise. I talked to @alexwlwsn about it as he had previously had a real HKS valve and it did the same thing. It must just be the design of the valve. SO like many before me I decided to get a tried and true tial 50mm. WELL.... the ebay version.
Before I bought the valve I checked my idle vac. It was between 21 and 23 so I ordered a -12 Psi spring "yellow" from ebay and I ordered an adapter. I could have probably gone with brown as well but the rating is the same.
I went with this vendor as the this was the newest knock off version and based on the Q series valve. I ordered a red one but they were out so purple it is.



I took it apart and it was already lubed with silicone but I still cleaned it all up as it had some shavings and stuff that was not cleaned. I then re-lubed it and put the new spring in.
It fits but my FPR was in the way as it is YUGE. I will need to re-think the placement of that. Not a huge deal right now as I am not running PI but that will be soon so I need to thing about that. For now I just hooked up the silicone line but I will be running a bigger line to the BOV as I have read it is important to use a larger line for the TIAL.
SO... the difference is night and day. The car idles smoother and pulls smoother. It does not have any hesitation or strange feelings at half throttle. I can barely hear the BOV on low boost which is sad but makes sense as it is a YUGE diaphragm. I am happy with the switch and feel like the spring I picked is the right one. I will update it more when have put some miles on it. The quality of the ebay valve seems to be solid as far as function goes but it is def not as nice as a genuine one in terms of feel and looks. The edges are rough and sharp and the coating already had a few scratches in it.
