I had a Greddy flange welded to the SC charge pipe. The Greddy BOV is broken, so I need to replace it. I have a Blitz supersound (older version with the big horn). It's going to be a lot of work to swap the BOVs, so I'd like to know if anyone has tried both BOVs and knows whether or not they can use the same flange?

 

Just from the look of it, I'd say no, but I did a rough measurement and it looks like it could fit. I know some people on the forums have swapped Blitzs for Greddys or other BOVs, so I hope they see this and let me know.

Thanks,

 

No it will not fit.

Definitely not. If it fit, I would have bought the Blitz BOV from a friend instead of having to help him sell it.

 

Well, hopefully I can repair the Greddy because otherwise it's ruined. I don't want to have to weld a new flange to use the Blitz BOV, but I also don't want to have to buy another Greddy BOV. What a mess .

 

I got a suggestion from members of the local import car club:

Tap new grooves and use a bigger screw. As far as I can tell, the pressure release adjustment for the BOV is completely controlled by moving that screw up or down the 1/2" tall hole. Is that correct, or does the screw press down on something further inside the BOV to adjust the pressure release point?
