Forge 004 will work on your car. You can most def run a BOV on your vehicle, but people on this forum board seem to frown down upon BOVs. Guess it is too "ricer" for them, even though it technically is not the correct valve to use. Anyways, you would need a dual piston unit which will keep the port closed at idle. And you will run slightly rich until the A/F is correct due to the metered air that is being vented.

ok thank you bro, what do you mean daul piston unit?

The design of the BOV will have one piston that keeps the port on the charge pipe closed at idle, since the vacuum on the nipple of the bov will open the side vents by lifting the main piston. On the Forge 004, there is a really weak spring that is in between the smaller piston covering the charge piping hole and the larger piston covering the atmosphere side vent. The purpose of the smaller piston is to simply keep the port closed during idle. Once positive pressure on the vacuum line is applied to the bov, the side vents are closed and the smaller piston already has done it's job.

get a forge splitter if you want best of both worlds

Im shocked that no haters cut u up for this. I have been leaning to a 60/40 dual port 60% recirulated 40% vented to atmosphere.
