I have a SSqV FLANGE and recirculation valve - waiting to buy the valve. I have a Blitz DD on a hardpipe for a MkIV, but I don't think I will use it. In fact, I might just sell it ad put the cash towards a SSqV.
I am seriously thinking about using the SSqV and replacing the fin insert with either a purple insert or just the recirculation valve fitting without hooking it back to the intake stream. This will be done after I do the 2JZ swap. It should give excellent holding and response without the annoying high-pitched sound indicative of the SSqV.
I hate to say it, but over time, I've seen that the SSqV is the BOV choice of ricers due to the noise. Now, most Honda kids are doing well if they at least turbo their car, but when they choose the BOV for noise over function, it's stupid. They want - no, NEED people to know that their car is turbocharged. This is unfortunate, because it IS a great BOV.
..then again, it's hilarious when I heard the SSqV described as " 'Scares old people' loud".
