OK, now dont flame me because i searched for quite awhile and if you have a link, you can just post that instead of answer my question if youde like. But anyway. If i have the hahn kit and i want a diff. BOV like greddy, blitz, turboxs, etc. Will it just bolt right up to the hahn kit? like can i buy a universal one? or if i need to buy something, what and where do i need to buy it? thanks a lot

just google whatever bov you want with "flange." i.e. "hks bov flange." that flange will need to be welded to your intercooler piping. then the bov bolts onto the flange.

flange is a really fucking weird word when said many times.

Most TurboXS BOV's will be a direct fit for the HRC piping. You also can get adapters for many other BOV's, and there is also an option of having the proper flange welded to your piping..

Also most companies make a adaptor plate. the HRC piping uses a 1" round beaded pipe to connect the bov to. Any BOV you get you can bolt on a flange to 1" pipe adaptor and use the standard silicone connector. if you are custom making your IC piping then just have the flange welded directly to the pipe.

I had the Turbo XS one and it does fit over the HRC location, and like the ^^ posts, just have a bov flange welded on.

if you have the hahn kit you can just order a bov for the gst or gsx b/c thats what i did and it slips right on... i mean... come on thats what bov you get in the kit.
