where is the BOV at on an 87 TII i cant seem to locate it. i know that there isnt ne real gain for having it scream but what the hell i think every one around me should know that i have a turbo. also how would one make the stock BOV make that noise? or do i need to purchase a new one which i erally dont wana do cause im not gonna mess with the turbo for a long time.

 

Bump

 

It is located underneath the front of the intercooler on the passenger side. You will see a big black hose coming off the intercooler....on the end of that hose is the stock bov.

 

you can vent it to the air but it requires a check valve. I don't know which one. I haven't done it. the BOV is in between the pipe going from the turbo up to the intercooler on the pass side. and it goes to the turbo inlet duct. it also has a vac line going into it. it's only about 1.5" round with a hose on either side

 

The stock BOV is actually a BPV (bypass valve) it is located on the passenger side of the intercooler and has a large hose going to the TID (Hose coming from airbox, and going to turbo), where it bypasses the air to. In order to make it atrmospheric, you must disconnect it from the TID, and plug the hole up in the TID to prevent any vacuum leaks (cork works fine). then so the bypass valve dosent suck any air in where it should only be releasing it you need a check valve which you can get at the hardware store. attach this on the end of the valve that went into the TID with a hose and some clamps--whatever is needed as long as you get it sealed from any vacuum leaks. If i can ever get a hold of a digital camera then i will take a pic of my setup. Hope this helps.

 

Yup it is pretty easy to do.

This thread might help, plus I posted a pick of the brass check valve that seems to work the http://www.rx7club.com/vforums/showt...threadid=29443
