ok, so i'm thinking about purchasing a universal blow off valve to instal on my1995 eagle talon tsi turbo (with gen 1 turbo swapped).
I have ZERO mechanic skills, but have been reading up online on how to install a BOV myself. looks pretty simple, just weld it onto the hot pipe:
My question is this, does it matter that my car already has a waste gauge? it refilters air back into the engine, will a BOV mess this up? or does it just replace it?
I think you're a bit confused. All modern turbo engines have a wastegate which diverts excess boost and if you didn't have one, you wouldn't need a DV/BOV. A BOV would be a mistake on your car as the 4G63 engine has a MAF air sensor and the loss of air from the valve would cause you to run rich. The car would run and make the pshhht sound but it wouldn't run well. If you want that sound I suggest going with an open element air filter which will let you hear the DV whoosh sound.
