Can any one point me the right direction of where I can find fitting instructions for a pair of bov's? just bought some HKS ones but with no instructions.

 

Thanks,

me I've use this :

 

BOV installation

thanks for that but anyone know how to fit the ones which fit to the large hard pipes on intake on top of engine, so you can see them?

I was at JAE on sunday and saw a Z with the hard pipe BOV installation is it a good way to be installed or can it cause problems?

Replacing your top intake hose with the Hard one's from Smithy and then modifying them to take BOV'S is the best place to put them as they are closest to the throttle boddies. Other guys fit them to the bottom 2 hoses which is crap because when your throttle bodies close all that air then get's forced back through the intercoolers into the outlet pipe from the turbo before it's dumped! Makes a good noise but you may as well not have dump valves for all the good it does. When your back on the throttle all that air has to then be re-accelerated again causing Major Lag!
