While I am at it, what compressor housings are compatible with the VF37? I am trying to find a compressor housing to have a 34mm restrictor installed on and just swap onto my existing turbo. And are any of thevf models a small upgrade while I am at it?
All RHF55 and newer RHF5HB (VF34, VF36, VF49) compressor housings are the same as far as the inlet and fitment. You can do a restrictor setup on any of them. You can pick up a VF39 housing put the restrictor on and use it on your 37. Just make sure you remove all of the RTV each time you swap housings. A scraper, and small SS wire brush work well for that.
