  • you guys are pretty good maybe a little more indepth for the not so car saavy. My question is ive heard that taking a factory blow off valve off and replacing it with a aftermarket blow off valve increases power but harms your turbo. Also someone told me you mus tchange turbos every 3-4 years! this sounds ridculous to me and frankly id rather a naturally aspirated engine if this is the case. If that is true then if you run on really low boost can you have sort of lifetime warranty on ur turbo?

  • @angrygunsmith Everything you've heard is rubbish. BOV does not harm your turbo. BOV does not give you more power (unless your old one is broken), you do not have to change your turbo every three years. Start getting your advice from somewhere else because who ever has been telling you this stuff clearly is not of this planet.

  • no, the BOV goes off when releasing TURBO pressure.. with no pressure their will be no noise.. so in short, no.

  • *quality cable ties* lol

  • @EarvinMendoza that's not a vacuum line if it's connected to your engine coolant. You can usually find good vacuum sources coming off of the intake manifold.

  • Hi guys at mighty car mods.iv got a 90 GTi-R.with an external waist gate an boost controler.wundering if can connect quod throttle bodys bov vac that goes to the bov an run my external waist gate line that connects to the boost controler an run that to the same line to the quod throttle body vac line to the bov?.a genuine reply would be much help cheers Bullet2380

  • @nathan270386 .From Bullet yous a srewable tye down thatal work im doing the same with my fully forged gti-r.

  • @mightycarmods lol trust me mate i knew it was bullshit just the guy who told me act like he completely knows everything. Thanks for clearing all that up for me, thanks for vids

  • what about rotarys? 

  • What happens if you dont block the factory bov vacuum line? Because i am new to installing a bov. I recently bought a 91 mr2 turbo and the guy installed the greddy bov himself and one of the vacuum lines is connected to the engine coolant and the other is connected to nothing and drips water. Im afraid to block it because i dont wanna fuck up anything because i love my mr2.

  • BrrrrrRRRRR .... PSSSHHHH :D
