Block-off plate. . . Necessary to go VTA??

Okay, so I have heard two different things from countless number of people. Here is the question:

In order to go VTA on a BOV, do I need a Block-off Plate? If so, where does it go, and do they make one for the KO4?
 
What a ricer. Your car will run like crap if you go vta w/o a tune.

Why do you think that I am trying to find myself a CPE Standback now. The Cobb was great and all, but I don't want to have to keep running back to Cobb in order to retune my car when I do something new to it. That, and I don't want to go to MDR to have them try to tune the Cobb and charge $1k an hour for him smoking the whole time.

So back to the initial question at hand. . . Do they make a block-off plate for the KO4 and if so, where does it go??
 
what the hell are you talking about? a blow off valve has nothing to do with a block off plate for the k04. all you do is cap off the recirc line back to the turbo inlet, but you need a blow off valve that is capable of running vta, don't think you can just do this to the stock valve and it will run right.

and if you get a standback you think you don't have to run back to someone to tune it? if you can learn to tune the standback you can learn to tune the ap.

Easy Bova. I know that you have to keep retuning the Standback, but _MSProtegy has some experience with it, so he can help me out a bit.

I have a BOV already, and have long been rid of the stock BPV. I was under the impression that I needed to have a block off valve for a BOV to run VTA, that's all. Since you have cleared up that misconception, I think that I will block off the return line to the TIP this weekend and see how I like it.

Hey Dom, have you heard from Reha lately??

By the way, does anybody know what size the vacuum tubing is?? I am trying to change out the nasty black ones that our car has to some nice looking blue ones from SU.

im sure you realize this, but just be prepared for lots of backfires, and overall running kinda bad when you test out the BOV setup without a tune. not the best setup to see "if you like it", only difference ofc will be sound at that point. (can always get a hybrid to run 50/50 if all u want is sound, will run better than pure VTA without a tune).

and yes, no block plate needed. just plug the recirc lines.

i cant recall the vac tub size offhand, but any mazda parts site will sell you the correct size if you buy the speed3/speed6 vac tubing.

I plugged my recirculation tube with a jack daniels cap. Works just fine. And the last time I talked to rehan was before Christmas.

I am only researching right now so I can prevent screwing up the 6. That's all.
 
lol ok all joking aside...if you get the turbo xs hybrid bov or a turbosmart 3 in 1 ... it bolts up to where the stock bpv came from ( no flange needed )...idk what your talking about in regards to what "flange you would have to use" unless you have a front mount intercooler...so if your looking for some help maybe you could go into a little more details on what aftermarket parts you have

Well from the looks of the Turbo XS, I would have to have some sort of mounting flange to be able to use it with my CX Racing FMIC. Or so I thought.

Yes. you will need a special flange for your CX racing FMIC. Any valve you buy for the mazdaspeed vehicles will have the stock flange. I would suggest setting up your Fmic to accept anything that fits the stock flange. That way your good to go with what ever fits the stock flange.

Well it has a "GReddy Style" Adapter already welded on from CX Racing, but I thought that I would need something for the BOV to mate up with it.
 
You would need a factory flange that could attach to a greddy flange. Just attach it face down, and use the backside to attach the valve of your choice.

Okay, it seems that you have caught me in one of my Duh moments and you have managed to confuse me. What factory flange are you talking about?? Would you happen to have a pic??
