You can, but it'd be amazingly pointless. The blow valve is needed on turbo engines to release the pressure that can build up if the driver goes off the throttle quickly and the engine revs drops fast. W/o a turbo you won't get any pressure build-up so there's no use for a blow valve.
It already has a blow off valve on it, and a rather good one.
Install a blow off valve, it releases excess pressure from the intake side of the turbo
Technically you can, but unless you have a turbo a blow valve won't do you any good. It's be like hanging sidepipes on a car and not hook them up.
not nesscearily but i suggest when you do that your car will be fast n better of quality
Nope, unless it's a fake electronic one.
how do install a blow valve on passa 1.8t 99
Stop being a ricer and give your grandma her car back. If you want a blow off valve. Have a shop professionally install a complete turbo set up.
yes
No
No, without a turbo, there is no blow off valve. However, if you really wanted to, they have fake blow off valves for sale. These mimic the sound of a blow off valve. It would be an absolute waste of money, but hey, it's your money.
NO
Amazingly pointless. The blow off valve is there to release intake pressure if you have the turbo spinning and then go off the throttle suddenly. If you haven't got a turbo there's no intake pressure to release if you go off the throttle.
