I am a little confused how to do this as I think the stock BOV is plastic and not metel, anyone done a change and has pics I would be very appreciative!

thanks in advance!!

 

There are a few BOV kits that come with an adapter to connect it to the stock piping.

 

dont mean to be noobish but I been having trouble finding one, could you direct me to one kindly!

 

Greddy type RS http://www.customcarscentral.com/gdy...mazda-rx7.html

 

thankyou! <3

 

Just a heads up - the Greddy RS is discontinued but the RZ (the replacement) uses the same flange. I don't know what the difference is between the two but they're used in the same applications.

 

BOV is more about personal preferences on the sound. I prefer the RS over the RZ.

But anywho, you really don't need a custom intake piping and flange and blabla. The stock hose form the intake to the original BOV is possible to get over a 25mm BOV nipple with some oil, heat and swearing.

The other end, if you are running recirc, is harder. I got a 25mm pipe and got it shrinked in a tube shrinker down to 20mm, so it fits into the pre-turbo intake bolt on. Haven't tried it yet.
