newbie with blow off valve question
My stock bow off valves have gone bad, is it possible to convert to one blow off valve. My mechanic has done it before but not on an Rx7. If not what is the best set up to go with? Any help is appreciated.

Check out this link for info on the CRV

Also, I believe the BOV is the one on top, and the CRV is the one further down...and if your mechanic doesn't know the difference, then your car is about to get f'd up.

As such, you can buy used stock bov's for very cheap - like a total of $30 for two. If your goal is to fix the boost, then do that first and install the aftermarket part after you've gotten it back up and running.
How do you know your stock BOV's are bad?

You can hear the air pressure escaping unless I am at almost full throttle, boost gauge gets to 5 psi and creaps higher, but you can hear the air leaking almost all the time

The charge relief valve is the one closer to the firewall, it is not a blowoff/bypass valve. The stock bypass valve is the one closer to the front of the car on the Y-pipe. The bypass valve releases excess boost pressure when you let off the throttle. The charge relief valve remains open while the secondary turbo is prespooling until 4500 rpm at which point the CRV shuts. So, you can see that those two valves, although they look very similar, have a VERY different function. Check both valves with a mityvac to make sure they work OK. Also check the 1" diameter hoses that those valves connect to. If they are hard and feel more like plastic than rubber, and you can rotate them even though the clamp is still on, replace them.

This seems like familiar territory......
Mine does the same thing. Can`t hear it when it is hooked into the airbox but vent it to atmosphere...Phissssssshhhhh! I am assuming that they are quiet from the factory but don`t know as I didn`t buy my car new. The valve checks out fine just no Phisssssshhhhh unless you vent it outside of the airbox.
