RastaMc Posted October 3, 2012 Share Posted October 3, 2012 Hi guys. I was wondering if someone could tell me in details where to place a HKS BOV on a VVT-i Twin motor. With pics if it's possible I was trying to find some info on the web but I only got something at the AU Supra site. Not much off course, otherwise I didn't call for help here:d I read about placing after the MAF. But how? drilling the IC-pipe? Solder it? And they talk about a recirculation valve that it's needed because of a VVT-i.... What do you do with the original BOV? Does someone has experience with this? Thanks Link to comment Share on other sites More sharing options...
Westy Posted October 3, 2012 Share Posted October 3, 2012 Just keep the stock BOV on a VVTi! Seriously! Link to comment Share on other sites More sharing options...
Swampy442 Posted October 3, 2012 Share Posted October 3, 2012 Why do you want a BOV anyway? On VVTI engines an external BOV can cause stalling, the ECU accounts for a certain amount of air going through the flowmeter, and fuels accordingly. When that air has been dumped the same amount of fuel is still injected. Link to comment Share on other sites More sharing options...
spikedjack Posted October 3, 2012 Share Posted October 3, 2012 Keep it recirc, using the stock. The AFM will shat its pants and over fuel the engine to buggery if you use a VTA BOV without a proper map. Link to comment Share on other sites More sharing options...
Geo Posted October 3, 2012 Share Posted October 3, 2012 VVTI = pain to mod, NON VVTI = Oh baby lets do it. Link to comment Share on other sites More sharing options...

keener Posted October 3, 2012 Share Posted October 3, 2012 I got an HKS SSQV BOV from Nik on here - came with pretty comprehensive fitting instructions and was v easy to do. Don't think I've got a VVTi though! Link to comment Share on other sites More sharing options...

RastaMc Posted October 3, 2012 Author Share Posted October 3, 2012 Nice pics guys. But do you have some from aside? So I can look at the connections. Thanks. Link to comment Share on other sites More sharing options...
Alex Posted October 3, 2012 Share Posted October 3, 2012 AFM based engines require the air that's taken in passed the sensor (at the air filter), to make it to the engine. This means you can't dump it to atmosphere. The VVTi uses an AFM (MAF) so you need a SSQV with a Recirculation kit. No reason not to have one just don't vent it to atmos unless you like your engine to run badly. VVTi's aren't hard to tune and in fact they have more range with the stock components. They just need different parts at times from the non-vvti. Link to comment Share on other sites More sharing options...
