I´m planning on using a bov from a friend. He has a 97 Eclipse, but its a BOV from a previous gen eclipse/talon.

question:
Is there anything special I should know about using a BOV? It would appear they all work the same, except for being an open atmosphere BOV or not.

Can someone enlighten me to differences and what to look for ?

The 1st gen eclipse "BOV" is really a by-pass valve. They are metal and considered an upgrade for the 2nd gens. Has it been "crushed"? Normally they bypass the air back into the intake just before the turbo, when the throttle plates are shut to prevent compressor surge. This is good for a car using metered air, since you don´t loose any air. If the valve has been crushed (you DSM buddy should know) then it is setup to vent the air into the atmosphere and make the cool pssshhh noise we all love. With a metered air car like the escort, this will cause you to run rich for a split second after the shift since the computer thinks there is a certain amount of air going into the engine when in reality it is blown out into the atmosphere. On my mazda I use a Apexi BOV vented into the atmosphere. It is a metered air car as well but I don´t have any driveability trouble at all. If the DSM valve isn´t crushed, then you need to vent it back into the intake. Otherwise your car will not idle. I could probably write a book on this stuff so if you need any other info, just ask. The 1st gen valve is a good valve for the money since it is so cheap. An aftermarket valve will run you $200 or so plus the welding to get the flange. Making the DSM valve work with your aplication should be relatively easy since they are really a universal item.

Well the main reason why I´m using his BOV is he bought a new Greddy TypeS so he said 50 bucks for the BOV, flange and upper IC pipe, and I know an Eclipse doesn´t run well with open atmosphere BOV´s, like the Escort. But for all this work of turbo´ing an escort I have to have the blow-off sound....besides its the only way a mustang will take me seriously when I rev up next to him


The BOV I´m buying isn´t crushed, but I can modify it.

The pre 95 BOV´s on the eclipse´s are better. Or you could get an XS BOV for around $120 I think. I would get something better then a factory eclipse one, but thats just me.
