I'm looking to get aftermarket blow off valves for my stock twins and am having a bit of trouble coming up with the ones i want that have bolt on adapters that will accomodate the ~20mm hose size that our stock valves use. The smallest i can seem to find (for the Turbo xs bovs, which are the ones i want...nevermind why) is a 25mm bov that is used to fit Jettas. They have kits to adapt to Dodge Stealth, 3000GT, 87-98 Supra, 99-01 WRX, Dodge SRT-4, Eclipse 1st gen, Eclipse 2nd gen, 91-95 MR2 Turbo, Nissan 200SX, Nissan 300ZX, pre-'98 WRX, Skyline GT-R, Skyline R32, Skyline R33, and even a Toyota Starlet Turbo (whatever the hell that is). I can't for the life of me find out if any of these equates to a simple ~20mm hose adapter. Does anyone have any clue about this? I'm going to be making some calls to find out, but i find it hard to believe than anyone i talk to will really be able to help me...or willing to. So if anyone is familiar with these cars and their bov fitments, it would be of great assistance if you could help me out here.

(And yes, i know i can get a kit for a Greddy Type S or Apex twin chamber. I just don't want either of them.)

If you can't help with the above, any other suggestions for fitment or adapters would be welcome. Thanks.

Have you tried picking up a phone and calling TurboXS? It would be VERY easy for their tech help to just measure their BOV adapters for you. If you can't find that, you can go to a plumbing supply store ("Hose Man" is local to me) and they should be able to find or build an adapter for you.

Actually i think i may have the answer. I was pretty frustrated last night and was having a hard time thinking. Heh. Anyways, the I.D. of the hose for the bov is 22.5mm. Turbo XS makes a bov specifically for Audi and VWs that has a 25mm inlet to replace their stock bosche unit. I have a friend who has a Jetta with a Forge bov, removed his and found that the 25mm inlet can be fitted to the 22.5mm hose without too much problem. (The hose is bascially coolant hose and is pretty flexible.) I just ordered two of those today. I really think this will work...and i don't even have to buy an adapter kit. If, for some reason it doesn't, i'll merely return them and call TurboXS and see if i can get some more info. They might be very helpful as you say, but i've dealt with enough companies to know that if you're looking to 'custom fit' one of their products to your car they're usually not much help at all. Thanks for the suggestion.
