I'm really wanting a bov but don't wanna throw any codes. I know it has an internal bov so to not throw codes do I need to buy a block plate then install the external bov?

 

You'll also need the upper charge piping to put the bov on. Yes on the block off plate and you might need to relocate the boost solenoid (has 3 vac lines and a electrical connector mounted to the turbo). I have the old k4 lying on the garage floor if you'd like pics. I have full zzp bolt ons. I know there is also the Forge BOV that will give you some WOOOSH. Shouldn't have any codes to worry about.

Mine WOOSHes like crazy now! Just fished a GEN 3/ Bullseye 256et swap. Got 200 miles on it as of today. I get to take out the break in oil and really start playing!

If you haven't seen it check out my "project overboard" thread in the SS section.

Good luck!
