do any of you have a b.o.v on your turbo 280zx whats the best place to mount it also does the stock turbo motor have a b.o.v cause i didnt see one i was wanting to put an aftermarket blow off valve on my turbo motor when i get it in also whats the best one to use any pics of it mounted on a 280zx would be great thanks

 

There is a stock pressure relief system on the piping from the turbo to the throttle body. It's a rubber hose that connects to other stuff on the intake manifold (I believe that's the manifold pressure release system too).

 

that is a system to prevent the engine from killing itself when you let off the throttly abrubptly.. so it channels intake air into the intake to keep the engine breathing.. the turbo motor does have a pressure relief valve (Pop-Off-Valve(POV)) and it is located right to the left of the EGR on the drivers side of the intake.. you can adjust this by grinding off the top of the cap and taking the cap off and and turning the retaining clip and pulling out the spring and inserting 1 1/4" * 5/16" auto body 'Fender washers' then replacing the spring n clip and when that is adjusted to your liking you can weld the cap back on...
A BOV (Blo-Off Valve) regulates pressure before the air goes in the intake and recycles.... a BOV is much better than a POV.. a BOV prevents the pressure from building to the limit.. a POV relives it once its already surpassed the limit...

 

This is where I put mine. But notice I don't have a stock coil...otherwise that would be in the way.

 

Bit off the topic but i have a turbo smart sequential bov for sale if you are interested pm me....

 

tickwon has his in the perfect spot.
