datsunscom Posted June 17, 2004 Share Posted June 17, 2004 Guys, I'm running a VG30DETT in my car and I currently have Bosch recirc valves set up as BOV's. I did this because I was unaware the Bosch valves CANNOT be used as a BOV because at idle / cruise these things DRAW air, so they need to be plumbed as recircs so the air they draw in is metered. In my case it'd be far easier to replace these with regular BOV's than to plum them as recircs. Does anyone have any recommendations on a BOV that would easily replace this? The Bosch has no flange so a BOV that connects the same way would be desireable. A picture of the Bosch valve is here: http://www.datsuns.com/Tech/BoschBOV.gif Quote Link to comment Share on other sites More sharing options...
Sean73 Posted June 17, 2004 Share Posted June 17, 2004 Audis, Porsches and Saabs use the same OEM Bosch valve. So there are a ton of aftermarket valves that can replace that one without mods. Perhaps some of the aftermarket valves can be run open to atmosphere like you want. Also, try reversing the valve, plumbing it backwards and see what happens. Try searching on http://www.saabnet.com, also http://www.s4biturbo.com/art-dvtests.shtml has useful info on the bosch valve.[/url] Quote Link to comment Share on other sites More sharing options...
