Don't know if anyone already posted this or if anyone knew about it, but Turbosmart now offers a BOV kit for the Stinger and Genesis 3.3TT

I worked for Turbosmart USA years back and I can attest to their high quality standards. From what I remember of these BOV's, they can be configured in recirculating, blow off, or combo with the included blanking plug. These would be the ones I would get if I had the money
