Are you sure you want to do this? as its not necessary at all to run one on any turbo charged car in my experience.

It almost certainly has a blow off valve fitted as standard. Down on the driver\'s side of the engine bay will be two little cylindrical brown metal widgets halfway along two of the 19mm pipes from the airbox. One is the charge relief valve, which you wanna leave as it is. The other is the blow off valve (make sure you get the right one, the former will have "CRV" written on it!). You can have it just vent to atmosphere, though it won\'t be deafeningly loud. Just remove the bit of pipe between the BOV and the airbox, and plug the hole it leaves in the airbox. The valve will now "dump" to atmosphere, it\'s only plumbed into the airbox to silence it.

Of course, if your car is already not stock, some of the above might not be exactly as described! If you want to do it expensively, the easiest way is to just replace the stock BOV with a nice aftermarket shiny one that makes a better noise..... or in the case of HKS SSQVs, sounds like a budgie in a blender
