I hope I'm posting this in the correct place. My car has a GReddy intercooler and piping. I believe the piping originally had a GReddy flange, however it looks like the HKS flange was welded on. My question is, does anyone make a adapter to put a GReddy bov on a hks flange? I would like to switch to a GReddy or my dodge garage 1g bov. Thanks.

Yes. I had the same problem, hks flange with ssqv bov. Found the adaptor on eBay. Make sure you look at the bolt spacing though.

I had to make mine, leaving the stock greddy flange on the UICP, then chopping a knock-off Greddy BOV to keep the aluminum flange, followed by a HKS Flange, and a small chunk of aluminum pipe. Welded together and finished much cheaper than buying it, believe it or not.

I believe my post is being misread. I was asking if anyone knows or makes a flange to go from the hks bov back to a greddy or 1g bov. I know they make a adapter to put a hks bov on the greddy flange. I want the opposite, and basically want to get rid of the hks.

Just cut the HKS flange off the greddy flange and sand it smooth again.

Well you see I have greddy piping, and originally it came with a greddy flange. The po of my car I guess had the greddy flange cut off, and a hks flange welded on. Since the piping and flanges are aluminum, I don't have the equimpment to have a greddy flange tig welded on. I had an idea of taking a 1g bov flange and having a appropriate sized washer drilled out, and mig welded to it. I just wanted to see if, anyone had ever heard of such an adapter. I wanted to try an avoid having to fab something up. In case anyone asks why not keep the hks? I think the hks is mad old, plus I think it's a knock off. I'd much rather just use my dodge garage 1g bov.
