MR2 BOV setup

Postby 2fas4u » Sun Nov 19, 2006 10:17 pm

say does anyone here with SW20 MR2 Turbo's running BOVs on Venting rather than plumbback? will venting really cause it to idle rough cos i have a Skyline turbo as well which runs with airflow meter n read somewhere n heard that full venting causes rough idle but when i bought it, it was already set up as full vent with no idle probs. so if someone could shed me some light would be great cheers. also what BOVs you running n how well does it perform over factory plastic ones. did u have a custom pipe made or did u just get a MR2 adapter.

Running an aftermarket BOV to atmosphere won't cause too many problems in a Gen II 3S-GTE, apart from slightly rich upshifts, and a slightly slower transition from off boost to on boost. However venting the stock BOV to atmosphere is likely to cause all sorts of problems because it's not just a BOV it's also a bypass valve. See viewtopic.php?t=47177 for an explanation ;)

Firstly the stock BOV is NOT plastic, it's metal though IIRC it may have a plastic top. Also it's the best performing BOV for the 3S-GTE by far. Any other BOV, with the possible exception of a genuine HKS SSQV, doesn't even come close. That said two of my cars have other BOV's on them, one has a Blitz, the other is of unknown origin which is plumbed back, both use adaptor plates to fit the 3S-GTE, but I'd rather have the stock one as I have no desire for the psssst noise.

If you wanna sell your stock BOV I'll buy it.
